FINAL DESIGN (FRONT)

MARK II PROTOTYPE (TOP) FINAL DESIGN (TOP)

IDEATION & DESIGN. REVIEW Phyllotaxis is best appreciated from above. Module 1 introduced the natural process of leaf arrangement around the structure of a plant in order to maximize sunlight absorption and rainwater channeling. My idea was to mimic this process but in reverse in order to explore the effects of light and projection from the leaf arrangement.

I then attempted to design this intangible concept using tangible materials and tools in Module 2. After digitizing the analogue clay model and modeling it using Rhino, I built the prototype using 150gsm white card and tested out various elements of the resulting prototype. The left series of images explore the effect of lighting and diffusion through the structure.

PRECEDENCE. REVISITED The 2D phyllotactic panel arrangement of the Eden Project educational building model has successfully mimicked the spiral formation that converges at the centre (tip in most cases). The orthographic view of my final design has attempted to mimic this as well. But instead of rectangular (or rhombic) panels I had to settle for tribasic because of the complexity of my shape and form. I had to be mindful of fabrication limitations!

The panels of the Mangal City skyscraper appear to be arranged phyllotactically around the main structure, which branches into three substructures. Their 3D shape was most appealing to me because it means they would diffuse light in an interesting way.

Close-up of individual panels shoes a bead-like translucent structure which would allow light in and out. I want to recreate this using 95gsm tracing paper.

These cup-shaped leaves resemble the panelling of the Mangal City skyscraper. I like how the light diffuses as a gradient through the semitranslucent tissue of the leaf. I want to mimic this by creating folds in my leaflets.

.DESIGN. HYBRIDIZATION Mark II Prototype Design obtained by tweaking control points from wireframe structure as well as removing panels from tips of main leaves to create opening for leaflets. Design obtained using 3D custom variable panelling along a spiral (Rhino Spiral function) curve attractor.

Design obtained by tweaking control points from wireframe structure of digitized clay model and lofting pairs if curves separately.

I also took my tutor's advice and did-away with the holes at the edges of the first (Mark I) prototype. I thought this was going to make assembling the structure very difficult since the holes would weaken the structure and it would not be structurally sound and collapse like jelly.

I was encouraged by my tutor to try and merge the two designs (on the left) as well as to stick with a single colour: white. I am very pleased with the result!

600mm

.FABLAB FILE. FOR MARK II PROTOTYPE

900mm I experimented with different 2D variable panels with holes resembling stomata around the base of the 2nd full-scale prototype. For simplicity, I manually created these perforations on my unfolded nets. I decided to use the FabLab laser cutter for precision work (since there were so many strips to cut and some were less than 5mm).

.CONSTRUCTION. MATERIALS Stainless-steel ruler used for straight cuts as well as going over weak score lines.

I decided to experiment with double-sided tape but it was not able to hold card-to-card that well. The glue was much stronger even though it took a minute to bond each paid of tabs! I Ended-up using it for attaching the battery pack to the inner wall of the base.

I used Scotch’s quickdrying Tacky Adhesive since it claimed to bond card-to-card in under a minute. It was also clear after drying which meant the overall finish would have a clean look.

Very sharp and effective ‘snap-off’ blade cutter for releasing strips from the cutting sheet.

This was overkill and didn’t turn out as well as I had planned. I should’ve gone with bulldog clips instead…but all in the spirit of experimentation! They were used to fasten tabs once I coated them with glue.

.CONSTRUCTION PROCESS. OF MARK II PROTOTYPE (1:1) I constructed a full scale prototype to test assembly, materials as well as the overall construction process.

My assembling strategy was to either assemble three separate sections and then put them all together (just like the super-block assembly technique mentioned in the lectures), or to start at the bottom and work my way up to the top, leaving an open seam that I could then 'zip-up'. I ended-up however taking the bottom-up approach but instead leaving a seam the entire length to zip-up; I zipped-up every 5 or so layers.

.DESIGN ADJUSTMENTS AND REMODELLING. OF MARK II PROTOTYPE Unrolled leaflet panel for nesting and fabrication

Tribasic 2D paneling from 3D custom panel Planar curve transformed to best-fit by 3D custom paneling tool

I made the point grid smaller (30 X 20) which subsequently increased the 2D tribasic panels larger. I closed the holes at the tips and replaced them with the custom 3D leaflet panel. 20 X 20

30 X 20 (Final model )

30 X 30

40 X 50 (Mark II prototype)

The tip (and a few joints in the midsection) got cinched & shredded by the laser cutter even though it has a very acute tolerance. The tabs were also far too small for me to glue them manually using my fingers. I also ended-up removing the holes and perforations because I thought they obstructed the overall look & feel.

.UNROLLING. FINAL MODEL GENERATING TABS WITH GRASSHOPPER I used grasshopper to create tabs and score lines. I used the Grasshopper plugin (GH08X_MakeTabs.gh) to add tabs, folds and cuts to each unrolled segment. After some experimentation with the parameters of the MakeTabs.gh plugin I settled for the parameters shown in the screen grab (RIGHT).

AUTOMATIC NESTING WITH RHINONEST

I spent some time researching auto-nesting scripts and plug-ins for Rhino to see if I could get the computer to automatically nest the pieces so as to minimise material (and time) wastage. RhinoNest optimizes position and rotation for cutting and is accessible as a plugin which can be downloaded from TDM solutions from within Grasshopper. RhinoNest can also automatically create labels for each unrolled surface! I nested segments within the recommended 900 X 600 (mm) rectangle(s). At first I used RhinoNest but this didnâ&#x20AC;&#x2122;t seem to work for me so I ended-up manually nesting to the best of my ability (and patience!).

EXPLODED AXONOMETRIC VIEW (BOTTOM HALF)

Step 1: I grouped the panels in each horizontal segment together and colour-coded them. Step 2: I used the panelling tools Unroll Faces command to unroll one segment at a time. Sometimes I would get overlapping panels which I then had to separate further into sub-strips. Step 3: I used the Grasshopper plugin (GH08X_MakeTabs.gh) to add tabs, folds and cuts to each unrolled segment. When unfolding the model I noticed that the tip had some errors. This might have been a result of non-planar faces created during the lofting phase of the contoured curves. I then got rid of the tip and decided to keep it open at the top because it looked better this way. I initially tried unrolling using a seam but this failed because Rhino refused to unroll regrouped segments.

.FABLAB FILE. FOR FINAL MODEL

Just like the prototype, I used the University of Melbourneâ&#x20AC;&#x2122;s FabLab to laser cut the unrolled and tabbed surfaces. I decided not to use the cardcutter because I overheard a few other students complaining about its accuracy as well as its poor reputation at keeping cut pieces on the card. I wanted to use mount board but ended-up using ivory card because it was thinner and more flexible which is what I wanted for my lantern. Ivory card was also more translucent and would therefore let more light through. It is a lantern after all! I used the same 95gsm tracing paper as before (for the Mark I prototype) and nested the panels and sent it off to the FabLab for laser cutting.

LEGEND

I marked end-tabs and narrow corners as score lines in order to minimize tearing by the laser cuter as well as to make sure all the pieces remained intact on the card for easier constructions.

.LIGHTING. MATERIALS & CONSTRUCTION 2 x AA (3V total) battery pack with ON/OFF switch to neatly house batteries.

Standard gain colourcoded copper electrical wire for the circuit.

I chose these batteries because I needed a longer-lasting powersource since I arranged the LED’s in parallel.

9 x 5mm clear 3V 120° LED’s. I chose clear and 120° because it light’s-up a larger volume of the inside of the lantern as opposed to a smaller angle which would focus a narrow beam which is undesirable.

LEFT I decided to arrange the LED’s in parallel in order to minimize the number of batteries required as well as to maximize the output performance. RIGHT The LED’s are spaced along the circuit based on the Fibonacci series. This ensures that light diffuses through the translucent leaflets optimally.

Masking tape for insulating naked connections as well as safety.

I was tempted to test the lanterns (Mark II prototype and final) side-by-side in my own living-room. They added an organic element to an otherwise contemporary setting. I was pleased with the results!

.MODEULE 3. REFLECTION Upon reflection, the fabrication process to me was a question:

How does an idea become realised using current tools & techniques? - Macfarlane, B The idea in my case was the ability of a phyllotactic formation to throw light in an interesting way, and the ability to turn 2D card material into a 3D lantern that realises this idea is the ultimate realisation. I initially had concerns about the limits of the laser cutter in terms of turning the smaller and more precision unrolled panels into shredded paper confetti as well as my own limitations when it came to putting it all together. But I learnt to have more faith and in technology and trust in my own abilities. I used a laser cutter for precision work (since there were so many strips to cut and some were less than 5mm). I also liked the score lines left behind as it adds a somewhat rustic effect to the overall appearance. I was considering using the stock 250gsm white mount-board for better structural support but then read another student's journal that claimed she struggled with this and that she had to do a lot of rework in going over score lines and cut lines. A more zoomed-in revisit of precedence revealed a key to my final panelling design, and the lectures really stitched together the fabric of the fabrication process. I really enjoyed the learning curve!

.CRITICAL. READINGS & ANALYSIS Lectures Power of Making lecture (10/9) introduced challenges in working with 1:1 scale. Showed how making things is a universal trait. Spoke about industrialization and factory (mass)made things. How robots have changed the process of fabrication & how we can all one day have our own fab-plant. Physical manifestation of virtual environments. Purpose of prototyping. Accumulating materials in assembly vs. integrated systems. Superblock. I liked the quote by Daniel Cahrny about serendipitous innovation through making without knowing exactly what it is one is making. Differentiated between certainty, uncertainty (risk) and free workmanship. The privilege of prototyping comes with indulgence in some extra money in the project. A prototype is a trial that the designer uses to test various things. Simulate the reality as close as possible even with a significantly scaled-down model. Showed a physical and digital prototype, which tests effects. The shadow effects that the table produced was similar to what I wanted to do with my lantern. Through the looking glass project was wonderful.

Digital & autonomous lecture (01/10) by Guest Lecturer Stanislav Roudavski talked about our co-habitation with other living things and how architects are working towards a sustainable environment. He showed preference to not use computers in an artistic discipline because it takes away too much of our creative freedom. The series of short videos were very interesting, in particular, the pre-fabricated brick facades built by autonomous flying robots ("Builders Of Tomorrow") as well as the standard 6-degrees of freedom robotic arm. The lecture also encouraged the new generation architect to learn how to program computers, therefore bridging the gap in limitations and flexibility of CAD authoring tools and software. My take-home message from this lecture was that form follows software and the limitations of our knowledge. Module 3 readings Making Ideas by Macfarlane, B. The article asks the question: how does an idea (form) become realized using current tools & techniques? One option suggests reverse engineering an idea in architecture could be the smarter way to go about the design process. For example, designing a building that smiles could be interpreted as "what if a smile could produce the architecture". Their Mason T project was interesting because statically represents growth of the occupants. The Georges restaurant project was interesting because its organic skins were only possible after transitioning over into the digital architecture realm. They kept referring to "volumes" of pockets within the development area where different compartments that make up the restaurant. Migrating their architectural skills into a digital space, they were able to virtually model the entire design process from conception to fabrication while physical models were built only to test out the physics in the physical world. Lastly, the bookstore was interesting because the idea of using an average-sized book for designing the small contents of the enclosure as an incremental space-maker was great! Gershenfeld, Neil (2005): Subtraction; Addition; Building Models. This article compared a variety of cutting and fabricating technologies â&#x20AC;&#x201C; the other end of the modeling program that we use to design and realize an idea. The technology behind the laser cutter was most innovative: invisible amplification of radio waves through invisible carbon dioxide gas emitted an invisible laser that was only visible when the material it was cutting started to burn. The ability to vary the power of the laser enabled the cutter to etch, mark or cut the material. Subtractive fabrication however wasted material unless special care was taken in arranging the cutting outlines in order to minimize waste. Additive fabrication included 3D printing where material used-up goes straight into the product. A third approach was equality fabrication where the â&#x20AC;&#x153;idea was to deform one part around another part, ending-up with the same amount of material in the new shape.â&#x20AC;?

REVISED PANELLING The initial panelling pattern caused problems with grid alignment. The ‘triangular’ pattern skipped every second grid point. This caused problems when creating 3D panelling as gaps would exist between the 3D panels and the 2D panels. One attempt to solve this problem was to group selected points together, however Rhino was not able to correspond these points with the offset grid. Another attempt involved custom drawing the 3D panels, which did work to a certain extent, however, this method did not utilise the more advance capabilities of Rhino and was extremely time consuming. A final solution was to re-panel the entire model using a different pattern. By using the ‘tri-basic’ pattern, a more uniform pattern utilising triangulation was achieved and Rhino was able to correctly create the 3D panels without gaps (as shown on the next page).

REVISED PANELLING I took a different approach with designing the 3D panelling for the model. I wanted to map the muscles of the arm by using a variable set of pyramids which are larger towards the biceps and triceps of the arm. I also left the remainder of the 2D panelling exposed to represent the fat of the arm. This approach of 3D panelling used a complex set of point attractors and calculations to vary the sizing of the 3D pyramids. Points in the 2D grid were selected individually at areas of the muscles, and offset using the point attractors. By doing this, 3D panelling was able to be executed through the base grid and the offset grid.

REVISED DESIGN The revised design made better use of the capabilities of Rhino than the previous design. In the previous design, 3D panels were manually created, which did not allow for a complex and interesting design. 3D panelling was too uniform and resulted in producing unaesthetic qualities to the model. I think the creation of an abstract model should be something that is interesting and stimulates curiosity. The 3D panelling failed to create this as each side of the model looked nearly identical. The variation of 3D panelling in the revised model created something that was more interesting as each side of the model was different.

Revised Design

UNFOLDED CUTTING TEMPLATE The initial unfolded cutting template involved taking horizontal strips from the model. This created complications in which strips would become very long, and would not fit onto the 600x900 mm card for fabrication. As a result, the model had to be cut into sections, which created confusion as to where components were to be connected. Colour references were use to resolve this issue, however due to the large number of strips throughout the model, all colours had been exhausted which would create further confusion. In addition, this method of unrolling was not economical as there was too much wasted space on the card.

Logical unrolling: colour correspondence and wasted space on card

3D model: colours used as reference

UNFOLDED CUTTING TEMPLATE Panelling was revised and set out logically and economically. The first strip represented the strip of panels at the bottom of the model, and each sequential strip was to be connected to the previous. The use of confusing colour correspondence and labels were eliminated. Unrolling the strips vertically rather than horizontally made efficient use of the card as each strip was uniform in shape, and able to be clustered together. Intersecting strips in spiral form were eliminated, making the layout of the panels quite simple.

UNFOLDED CUTTING TEMPLATE By using Rhino to calculate the area of the surfaces of the unfolded cutting template, the wastage was able to be calculated and compared to prior unfolded cutting templates. In the original cutting template, a wastage of 73.7% occurred. This was due to inefficient unfolding techniques, particularly from unfolding horizontally. Each strip of panels varied in size, and this made it difficult to compress the strips on the template. By revising the unfolding technique so that the panels were unfolded vertically resulted in a linear arrangement of strips that were easily compressed on the sheet of card. As a result, the wastage was much less at 56.1%. This is a saving of 17.6% of material. Additionally, only three sheets of card were required compared to five sheets in the original template. Left over bits could be used in the original unfolding for manual cutting of 3D panels, etc. This is perhaps not practical in the revised unfolding as there are no practical areas to make any further cuts or use of the waste.

In order for the strips not to disjoin from the card after being cut, etch lines were set on each side of the strip. To enhance precision of the cut, the etch lines were set on the tabs, which would later be hidden.

Black lines = Cut, Red lines = Etch

These tabs were removed as other tabs would connect to these sections. In addition, it would be difficult to add tabs in these sections as they would intersect with other tabs.

PROTOTYPE 1 I was initially concerned that the ivory card would create a structure that was too flimsy. After creating a partial prototype, I was Material: Ivory Card

able to confirm this. By applying light force onto the model, the model was able to severely damage. The greatest amount of

Weight: 250 gsm

stress was on the spine of the model (which contained the windows). I found that some of the larger windows were unable to

Machine: Card Cutter

withstand the stress placed on the structure. In addition, I found it very difficult to work around these areas. Connecting panels to the larger windows was very tedious as the windows were very prone to tearing. In modifying the design of the model, I would

have to reduce the size of these windows. Using the card cutter produced rough cuts, particularly on the score lines. I was concerned that this would impact the final aesthetics of the model as it contains a large number of score lines. The laser cutter may therefore be a feasible option in eliminating this problem (in the use of black card, as the laser cutter will produce burn marks on white card). The biggest problem with ivory card was when the model was illuminated. The tabs were able to be seen through the card, distracting the viewer. This eliminates the possibility of using ivory card in the final fabrication.

Larger windows caused structural problems

PROTOTYPE 2 This partial prototype explored a different system of connections. I found gluing pairs of tabs together created stress problems Material: Paper

on the panels. Tabs had to be bent at 90 degree angles, and gluing them together was therefore very difficult. I wanted to see

Weight: 80 gsm

how the model would connect by using an overlapping system of connections. This replaced TAB-TAB connections with TAB-

Machine: Inkjet Printer

PANEL connections. The results were much more effective in holding the structure together. It also allowed for neater joints where tiny gaps produced by TAB-TAB connections were eliminated.

Using super glue was very time consuming and created messy results. It also produced glue smudges on panels. I wanted to try a different method of adhesive: glue tape on a roller dispenser. This reduced fabrication time by an enormous amount. All tabs on a panel strip were able to be connected at once, compared to individually gluing each pair of tabs using super glue. In addition, it was much neater in which glue smudges were eliminated.

Gaps were eliminated from TAB-PANEL connections

Less stress was imposed on tabs

PROTOTYPE 3 A full prototype was constructed from black card using the laser cutter. I had opted for the cutting template to be cut on 300 Material: Black Card

gsm black card, however, the FabLab had stocked the card incorrectly, and as a result, cut it on 200 gsm card. Due to time

Weight: 200 gsm

and transport constraints, I was unable to wait for another cut on the correct card. This perhaps emulates what happens in the

Machine: Laser Cutter

fabrication industry where suppliers do not provide the correct materials. Fabricators have the option the wait for the correct materials to be provided (leading to project delays) or work with what has been provided.

Constructing this prototype was very time consuming, however, identified a number of issues. The card was far too thin to withhold the stress of the structure. It was not able to stand upright. This prototype also used TAB-TAB connections, which were unable to properly connect the structure given the stress caused by the 90 degree connections. It was essential to implement TAB-PANEL connections in the final model, as experimented in Prototype 2.

FINAL FABRICATION The final fabrication involved cutting the unfolded template on 300 gsm black card, using the laser cutter. In addition, 3D Material: Black Card

panelling was cut on 200 gsm black card, as it allowed for greater flexibility in bending the card. The 3D panelling does not

Weight: 300 gsm

provide any structural support to the model, and so the structure will not suffer from this.

Machine: Laser Cutter 300 gsm card provides the structural support to the model, while allowing the card to bend into place (thicker card such as mount board was found to be difficult to bend into place). Black card was also used as it would eliminate tabs to be seen through the card when the lantern was illuminated and would not suffer from burn marks (as was the case with ivory card). A combination of glue tape and super glue was used to connect the panels together, and a TAB-PANEL connection system was incorporated in the final model. The final fabrication involved four stages: 1. Constructing the 2D panelling

Glue tape was applied to tabs

Strip was curved to form shape of model

2. Attaching the spine The model at this stage was not rigid, and needed the support of the central spine. This spine also has windows to allow light to pass through.

FINAL FABRICATION 3. Attaching the 3D panelling

3D panelling was constructed out of 200 gsm card allowing for high stress bends. The glue tape was not strong enough to hold the tight bends of the 3D panelling. Super glue was therefore used to attach all 3D panelling. The panels were folded together and then attached onto the model. 4. Adding the light circuit

All three LEDs were linked together in a circuit. A switch was added to enable easy functioning of the LEDs. The circuit was attached to the interior wall of the model to allow the arm to fit inside the model. I had wanted to implement an addition six LEDs to the other sides of the interior walls, however, supply constraints restricted this.

FINAL MODEL

REFLECTION Module 3 has proved to be the most difficult, but rewarding module. It has tied in everything that has been developed to this point. When I first started Virtual Environments, I had no background or idea about design. I found it difficult to understand why I was being asked to draw ideas from nature to design a lantern. Prior to this, I would have picked up a pen and paper and drew a square - that would be my lantern. I am now amazed at what I have achieved and what could be made possible using advance software such as Rhino. This subject has completely changed the way I think about design. Fabricating my model was extremely time-intensive and tedious. Prototyping was such an important tool in achieving my final design rationale and developing my fabrication technique. Many lessons were learnt, and each sequential prototype was improved from the previous, ultimately resulting in my final model. I found Stanislav Roudavskiâ&#x20AC;&#x2122;s lecture on augmenting space to be very interesting as it opened my awareness of how computers and technology have aided in the creation of extraordinary designs and structures. The work produced by algorithm editors such as Grasshopper has inspired me to experiment with the software, and understand how the automated tab script works. Further experimentation into the software allowed me to create simple 3D designs, which could act as a innovative aid in future design and development. The Macfarlane reading focused on creating ideas and using technology to influence design. The case study on Restaurant Georges demonstrated particular constraints faced by architects, and how the aid of computer technology can overcome this by providing a much more advanced method of design and analysis that would perhaps not be able to be done manually. The capabilities of Rhino have allowed designers to create innovate and complex models, that can be easily communicated across to engineers and builders. Rhino has allowed me to produce something that I would not have been able to create without the use of technology. The complex calculations in creating my model (from lofting to panelling to unfolding) would have been impossible to do otherwise. Technology is further developing and I think it is important to develop skills in this area to achieve radical results and outcomes. In the Gershenfeld reading, different types of fabrication techniques were explored. This included subtractive and additive techniques. This method of fabrication for this project is a subtractive form of fabrication. This, as a result, produces waste and prompted me to think about how I can limit the amount of waste produced. It is important to achieve an optimal fabrication layout that will reduce waste and increase efficiency in the use of materials. One of the most promising additive fabrication techniques is 3D printing. This revolutionises the way designers and engineers can prototype their projects. These services are becoming more affordable and after investigating, I found that 3D models can be submitted online to be fabricated and delivered within a few short weeks. This would be highly productive in prototyping future projects (small models of buildings, furniture, etc).

natural process & abstraction derivation of design: the form represents seasonal variation in coral density

coral growth a highly complex and intricate process.emerging 542 million years ago, coral organisms are not single entities, but colonies of genetically identical polyps (microscopic spineless animals) structural variation is generated by the genetic characteristics of the particular polyp species inhabiting the form.

clay model of final design

coral is built by the accumulation of calcified polyp ‘skeletons’ and through reproduction, both asexual and sexual.. asexual reproduction budding (chipping a tiny portion off a whole polyp) or division (halving of a polyp).. missing parts regenerate and the process is repeated. sexual reproduction releasing gametes during a synchronous spawning event.. gametes fuse to form planulae, fertilised and micrscopic larva that eventually settle on a solid surface to begin a separate coral colony. coral have evolved to spawn during calm conditions, with reproductive periods varying according to regional wind and current patterns. the date of the spawning event is controlled by the lunar cycle and the time by the solar cycle, not by a ‘circadian rhythm’: coral spawn at sunset on the full moon on sunset. the growth rate and structural character of coral is influenced by: fluctuations in sea-levels light intensity (photosynthesis) water temperature carbon dioxide concentration pH + salinity, and ocean currents (delivering nutrients) coral growth is cyclical, varying according to the season: growth rates are higher and the coral structure less dense in summer than in winter (due to increased water temperature and light intensity)

response to readings/lectures on the theme of fabrication gershenfeld: equality fabrication while not strictly ‘equality fabrication’, material consumption can be optimised by arranging the 2D elements in such a way as to leave as little negative space on the cutting template as possible. sharing lines between the elements might be a way to achieve ‘equality’, but it would restrict the object geometry to a symmetrical or repetitive form. after my initial prototypes, i was able to reduce the spacing between the elements.. having some experience with the card/laser cutting process, i was better able to judge the limits of the fabrication tools in terms of the minimum spacing needed, and therefore reduce the wasted material. digital design and the division of labour digital modelling and fabrication challenges the division of labour by dissolving the boundaries between conceptualisation, representation and construction. in other words, digital design tools empower the designer and allow involvement in every step of the process of creation. macfarlane: making ideas parallels with macfarlane’s digital design philosophy: 1. inability to express the model in traditional 2D format.. a 3D digital model allows the designer to specify complexities of surface and geometry with far greater freedom.. 2. working “fluidly with conventional and digital media”, switching from hand sketching to computer modelling and back agin throughout the design process. my ideas were in a constant state of fluctuation, exploring variations on my original concept right up to the fabrication stage. event as generator of form in designing the interior of the Florence Loewy Bookshop, macfarlane based the form on an imaginary circulation route, modelling on a 3D grid, informing the location of the book “islands” virtual environments

Module 3

Hello people! I am Petals. Welcome to my life!

Standing with imperfectionsâ&#x20AC;Ś Module 2 Development

Prototype I 1. Scattered Lights The triangular holes allowed too much light to penetrate, scattering lights in all direction without highlighting the spiral trench.

When better is possible, good is not nearly enough. Design Optimisation

2. Four-sided Trench Faces The trench faces in their four-sided polygon form did not lie on the same plane, hence when unrolled in the same form and constructed physically the polygons did not fit into each other.

Trenches

Precedent : Stone Spray Project Architects : Petr Novikov Inder Shergill Anna Kulik Location : Institute for Advanced Architecture of Catalonia Stone Spray is an on-site robotic 3d printer that creates architecture out of soil. The technology uses sand as the major material in creating structures. A series of experiments were conducted on the proportion of materials that would achieve the best end results, one which is strong and yet a minimum amount of setting time. Very much like the project, the model made out of paper experimented with the different thickness of paper. A thicker paper provides a more rigid structure but is more difficult to create a clean bend especially with small triangles, and thin paper works the other way round. Using the 200gsm card has allowed a fairly rigid structure to be formed with a minimum amount of creases at bends. When working with materials, testings are often required to fully understand the properties as they vary with usage. Reading the technical diary, it was realised that one of their major concern was with the drying system. The wet sand when piled together requires a long period of time to dry and hence to improve the system, while building, the team started shaping holes-structures to let the material solidify faster. In building the trenches of the petal with paper, the paper due to itsâ&#x20AC;&#x2122; properties causes the structure to fail to close precisely. Not able to change the properties of paper or sand, the structure was changed. Gaps were inserted in between the trench to allow spaces for the paper to move around hence avoiding the failure at the connections.

b. Messy Trench Gaps The spiral trench do not exactly fit with the outer surface leaving gaps and squashed faces at the connections, although it was possible to close the surface.

a. Triangulate Trench Faces The four-sided trench faces are triangulated as triangles do not deform and remains on the same plane under pressure.

c. Redesigning the Trench The redesigned trench not only inserts gaps into the trench but gives a uniform direction of triangles resulting in a neat and clean trench surface. With the new design, the trench and the outer surface connections no longer leave gaps and squashed faces.

a. Triangles to Arrows The triangular holes were converted to arrows. The change reduces the surface areas of holes, reducing the amount of light penetrating the surfaces to allow more lights to focus on the spiral trench.

1. Triangular holes with varying density were populated on the surface using the ‘pt offset faces borders’, applying the ‘point attractor’ option.

2. Offset mesh to 2 different distances.

2. Drawing lines on the unrolled strips, the triangles were manually changed to arrows.

3. Join outer surface with trench faces in pattern shown. From petal 1 to 5 (left to right), the direction of the arrow varies, with the principle ‘hot matter rises while cold matter sinks’. Petal 1 and 2 at the higher temperature end has arrows pointing upward, vice versa. Petal 3 whereas has a mixture of upwards and downwards arrows. Arrows were attempted to be populated on the surface using the ‘Custom 2D’ and ‘Create 2D Pattern’ options, which turned out unsuccessful as the arrows did not fit and point in the correct direction on the diamond-gridded triangle faces properly.

1. Close trench gap with surfaces, mesh and join to form one mesh.

4. Delete mesh, close base with surfaces.

b. White to Black Even though with the reduced holes of the outer surface and the increase in gaps at the trench, the spiral effect of the petal was still not highlighted. To further to reduce the penetration of lights on the outer surface, black paper was used instead.

Overall Structure a. Handle In order to hold the structure in itâ&#x20AC;&#x2122;s angles, a bar is used to hang off the structures. The bar has a similar structure as the column.

Using the same amount of lights, the black and white model disperses less light but creates obvious spots of lights on the surface. The contrast between the trench and the outer surface is however clearly highlighted in the black and white model.

Supporting Columns b. Columns are added to the individual petals to allow the petals to be hung securely without tearing the material.

The columns allow lights to be attached hence creates a distance between the lights and the surface, creating an evenly distributed lighting without obvious spots of light on surfaces as seen in the previous image.

Part 2 : Cutting me out. Fabrication

The unrolled strips are nested and sent to the fab lab for fabrication. As no dash lines were needed and the â&#x20AC;&#x2DC;rustâ&#x20AC;&#x2122; effect of the laser cutter on white cards was undesirable, the card cutter was used instead.

My growth Chart. Module 1 to 3 Development Progression Module 1

Module 2 Module 1

Reflection Module 3 was basically making lots of prototype, it is a vicious cycle, you built then realise something is wrong, turn back to the digital file, change and built and then realise something else is wrong now… Having built prototype after prototype, I wonder if it was at all possible to see it all from the digital file or at least with the first prototype, the flaws and the improvements required without building one after another. The digital software are such sophisticated programs and yet they fail to help you realise that the model just would not work when constructed physically. As troublesome as the process was, I came to realise that it is this prototype-making process that has allow the development of ideas and if it wasn’t for the process, some ideas might never occur. It is the experience gained that has broadened our views helping us come up with tangible solutions. Then again, this process has revealed the limitations of the digital program and that it can only bring a design to a certain level and the real properties of the material can only be fully tested and understood by prototyping. And while immersing in the prototype-making process, changing and adjusting for the better, there can never be an end to it. At some point, you’ll have to pull yourself out from the cycle and start moving on to the next stage. There are other factors besides ‘perfection’ that needs to be considered such as time and cost. Although not in the business industry, and money does not exactly equal to time yet, we are still bounded by deadlines and the cost of making the prototypes. Thou there is no real way to tell when one should stop, mine was the submission date.

1st Prototype â&#x20AC;&#x201C; Unrolling & Nesting

When I was unrolling the first prototype, I selected each surface one by one without any other help to distinguish surfaces on different strips. This not only took me a large amount of time and energy, but also led to a big mistake which I didn't realize until I was building up the prototype.

1st Prototype - Construction

1st Prototype - Light Effect

Although only the 2D part is completed, the light effect is still tested. The shadow of the bottom part casted to the ground is similar to my expectation. But It seems that little light can go though the upper part of the model.

1st Prototype - Problems & Potentials

The most important problem with my first prototype is that one of the strips cannot fit with others. This is because I selected the surfaces of the adjacent strip when I was unfolding the model. So I think I need to change each separate component of the model to different colour before I select the surfaces and unroll them.

By observing the light effect of the 2D part of the first prototype, I find there is not much light going through the model when it comes to the two ends. Since the original design of the 3D part is fully closed, thus even less amount of light will go though the model, which is different from what I expect. I want more and more light going through the model from two ends towards the bottom of the model. Thus I decide to change my paneling design.

A large amount of space on paper the is empty and wasted. Thus The nesting of strips for the 2D part can be rearranged closer to each other so that waste of material can be minimised.

Precedents

Mangal City by Chimera The designer of this skyscraper get inspiration from mangroves. There are a number of individual office/residential "pods" sit on "branches" that actually twist towards the sun to maximize warmth, light and photovoltaic (solar energy) potential.Â These little spaces extruding from the hollows of the inner structure of the building tries to express â&#x20AC;&#x153;the emergent logics of adaptation and evolution that are constitutive of ecosystems in natureâ&#x20AC;?, both physically and functionally.

2nd Prototype â&#x20AC;&#x201C; Design Optimization The precedents mentioned above inspires me to recreate the 2D and 3D paneling of my model. I enlarge the hollows on the 2D paneling surface so that more light can go through it and cut off half of the original pyramid 3D pattern. In this way, the amount of light coming out from the lantern is no longer controlled by the the 2D paneling surface but the semi-closed 3D structure. In addition, the 3D structure also creates a sense of flow and movement, which makes the structure of my model stands out.

2nd Prototype â&#x20AC;&#x201C; Unfolding & Nesting

Fablab File - Ivory Card White

2nd Prototype - Construction

2nd Prototype - Light Effect The light effect of the second prototype is closer to my expectation, which has small pieces of light scattered at the top and a web-like shadow at the bottom. But I find the 3D structure still blocks too much light at the top. Also, the 3D structure is not emphasized enough so that it can be easily distinguished from the 2D part. My design aims to show how adaption happens from at individual level to the species level. Thus the 3D part of the model, which is made up by a number of small modules, should stands out and then fuses with the 2D part. So I think the 3D part needs to be further modified.

2nd Prototype â&#x20AC;&#x201C; Problems & Potentials

Since I build up the 3D modules on the fully completed 2D surface directly, sometimes I have to rotate the whole model so that I can get those modules stuck to the 2D surface. During this process, the 2D surface has to experience unnecessary pressure, which leads to cracks between some strips. Also, I cannot really make these modules get strongly stuck to the paper underneath so I have to use tapes to hold the 3D structure from falling off, which really damage the external beauty of my model. Thus I think in the final model, I'll separate the strips that have 3D structure on it from others, so that the damage to the 2D part can be minimized and the 3D part can be built more easily.

Precedents

Project of documenting the Philips Pavilion The project was initiated by documenting Le Corbusier's Philips Pavilion (1958) through Rhino as a mean to investigate the materiality and non-linear geometries. What really attracts me is how black and white interact with each other and then produce an quite expressive look of the material behaviour of water under sound wave. The use of different colour adds complexity and diversity to this building.

Final Model â&#x20AC;&#x201C; Design Optimization Inspired by the precedent mentioned before, I decide to use black card for the 3D part. Since black card can block more light than white card, I recreate the 3D paneling with a series of custom 3D patterns that have different sizes. The 3D custom structure gets smaller when it move downwards from the two ends. Thus more and more light can go through the model from the top to the bottom and a gradually changing shape of shadow is expected. This design also reflects my natural process, mutualism, by emphasising how adaption starts from individuals and spread to the whole species.

Final Model â&#x20AC;&#x201C; Unrolling For the 2D part, each strip can be identified in two ways, the colour and the label. Different colours help me to distinguish small surfaces belonging to different strips when I'm selecting surfaces to unroll them. The labels help me to assembly these strips together in the correct order. In addition, the starting and end triangles of each strip is tagged with their name so that it is easier for me to follow the model to fold each surface in the correct way. Grasshopper is used for generating tabs for each strip.

Final Model - Unrolling I also use grasshopper to generate tabs for each unfolded module. Although there are only two tabs needed for each module to connect with the 2D paneling surface underneath, I choose to keep all the four tabs in case I delete the wrong tab because the length of the sides of these modules are very similar.

For the 3D part, each unfolded module can also be identified by the colour and its label. Since there are only a limited number of strips in the 3D part, so the colour is used for indicating the sequence of modules in one strip rather than specifying strip the module belongs to.

Final Model - Nesting Ivory Card White â&#x20AC;&#x201C; 2D part

Black 200gsm â&#x20AC;&#x201C; 3D part

Each line is allocated to a specific layer with a corresponding color. Red lines are in "score layer" and green lines are in "cut layer". Also, these unfolded components are nested to be as close to each other as possible to minimise the cost and waste.

Final Model - Construction

Final Model - Light Effect

This is the final outcome of my design. Both of the physical structure and the light effect express the my natural process, mutualism. Particularly, I want to show how the interactive adaption of two species that rely on each other for survival and how the adaption starts from individual level and become important for the whole species.

From the top to the bottom, The black 3D modules get smaller and closer to the 2D surface and the light changes from patches to a web- like shape.

Critical Analysis & Reflection In the third module, we are required to transform our digital model into a physical paper model by going through the process of unfolding and fabricating each component of our design. The lectures and readings introduce a variety of computerised controlled cutting tools, some of which are used for cutting our template as well. I think these advanced technologies play an really important role in the fabrication process in modern world. They significantly improve the efficiency of the building process in terms of time and material use. Since we can arrange what needs to be cut on the computer, it minimizes the possibility of mistakes and thus the waste. These tools acts like the basis for a making successful model.

During Module 3, I also have an experience of learning from practice. Gershenfeld's paper (2005) discusses the distribution of labor in the process of making an object. It has been a fact for a long time that designers, engineers and builders are in charge of different stages of this process but with the advent of 3D modelling, the boundaries between them are blurred. I feel a strong sense of agreement with this statement when I'm working on the module 3 task. When I am building my model, I can feel which part is hard to connect to the others, which part is less stable than other ones or which material is better for constructing certain component. Building actually helps us to find out problems and encourages us to test different solutions. So I not only care about the external look of my model but also the internal structure and the viability of my design, just like an engineer or builder. Building something up can provide designers with different perspectives to judge his/her design and give them more inspirations to modify its design.

Module 1 + 2 recap

My natural process are the dance of spiders. The curvature nature of such dance is shown through my design form. The patterns developed are from the growing veins of mould slime. Through the teachings of Kandisky, the veins are broken down in simple rectangles to form the pattern above.

Change in pattern

I realised that using the first pattern would present many problems. Being â&#x20AC;&#x2DC;boxedâ&#x20AC;&#x2122; â&#x20AC;&#x201C; walls on every side, these walls would over lap with neighbouring walls. To overcome this issue, I simply removed the side walls, and planned on manually adding such walls when needed.

Final form

This form is much easier to make compared to the first one shown in module two. There are no overlaps, and the â&#x20AC;&#x2DC;cutsâ&#x20AC;&#x2122; are smaller, thus much more easier to handle.

Layering

Firstly I layered the model horizontally, with both and bottom segregated. It was done horizontally as it would be the most easiest to construct, as told by the teachers in the rhino tech section, I spited the top and bottom in half to present any possible overlaps,.

Tabbing

Before unrolling each sections, I wanted to know which tabbing system I needed to use. After experimenting with both the tabbing options in panelling tools and grasshopper, I found that both produced tabs within the area. I need tabs only on the outside,. After speaking with the teachers in the Rhino tech session, I found it was better if I manually drew all the tabs.

Unrolling

Image above shows the entire structure unrolled. The original unrolled section is kept next to the one prepared for print â&#x20AC;&#x201C; ones altered primarily due to overlaps within the panels. The original one is kept to act as reference

Unrolled sections

Unrolling back hand

Unrolling finger pieces

File prototype for Fab lab

Changed to A4 size

After some misunderstanding with Fab tech, I thought the only option for me to cut this is via hand, as my pieces were too small to cut on both laser and card. I only found out after that I could only use laser. This is why I fitted all these pieces on A4 boxes, so I could print at home

Building full scale prototype

Spent two weeks of my holidays manually cutting and gluing each pieces. This method is extremely time consuming, hence in the future I will try to avoid this approach. The errors I found were misalignment, missing tabs, and tabs that were too big or small. I adjusted such on rhino. I also decided not to include the panels that formed the wall in the cuts. These just took too much time and effort to connect.

Building full scale finger prototype

Building the finger prototype had many issues. Being a 3D curved form, the bottom of the structure wonâ&#x20AC;&#x2122;t properly attach to its neighbouring sections. Not only that, due to tits small size, gluing and folding was extremely difficult and took a lot of time. To resolve this issue, I decided to make this 2d instead of 3d, by simply removing the bottom section.

Building the circuit

Location of diodes and direction of light

Simple circuit

Simple circuit adjusted to fit fingers

Had to use a combination of both series and parallel in order for the circuit to work using a 9v battery. If I only used series, only 3 diodes can be installed. And if I only used parallel, the diodes will overload in volts. Series and parallel is done to adjust volt input and to have more diodes in the circuit The LED I used are white 3mm diodes with min 3V and 3.4 V typ.

Building the circuit

Through calculations using the basic laws governing electricity and circuits, I was able to successfully create the circuit â&#x20AC;&#x201C; all the diodes light up. However this circuit used a lot of power. With a fresh out of the packet 9v battery, the circuit only lasted approx. 5 seconds before the battery died out. I need to think of a more efficient way to light up my model.

Building final

Final model

Reflection Model 3 was primarily based on constructing the model, which was a great learning experience. By virtually designing the model, and then constructing it in real life, I learnt the great importance of producing prototypes. Despite calculations, and having things look ‘right’ on the software, these results cannot match those of building a real model. I spent a great amount of time constructing my model as accurate as possible on the computer, but building it showed many of my calculations were off. For instance, I did not take into consideration the thickness of the paper, the flexibility and the folding behaviour, which made my unrolled sections quite inaccurate. Through the reading ‘Making ideas’, by B. Macfalane, I learnt the great influence virtual plays on the design world. Physical designing have some form of limitations. Accurately visually presenting what’s in your mind, correcting mistakes, adjusting certain aspects are all large hurdles to overall through basic physical design means. However, virtual design overcomes such limitations, and opens to a greater vast of possibility. I also experience such effect whilst working on rhino. The more I worked, the more I learnt of the possibilities rhino gives. From converting hard mundane task, to a quick stroke of a button really makes rhino a enjoyable software. Not only that, the knowledge gained allowed me to think of more patters, more designs I could potentially use. Building my final, I did encounter some issues. The paper for the final was much different to the paper I used to create my prototype. It was stiffer, thicker, less flexible and stronger than my prototype paper. From this it lead to a few complications. The solutions used to resolve issues for the prototype, are only for the prototype. It does not greatly affix to the final due to different papers. Whilst the prototype was able to fit in correctly together, due to the thickness of the final, some areas did not fit as perfectly as desired, leaving gaps and imperfect folds. Next time I would use the same paper for both prototype and final. In all, I learnt the importance of testing and reflecting. Only through these are the problems effectively solved. No software or calculations can accuracy mimic the means of reality. If given more time, I would spend a great deal of it constructing more prototypes to get the design spot on.

up and down lines in zic zac way

The reason why the up and down lines pattern will be my final hole pattern is because this is actually my original pattern about the flying process of butterfly. The distribution of the holes will be allocated according to whether the lines are passing through or not, therefore, it is pretty random too. My up and down lines are not drawn evenly but instead, some parts are having more holes and some parts are having fewer holes as I have applied the case to the situation when I wear it. Because Iâ&#x20AC;&#x2122;m going to put my hands through it horizontally, if there is going to be holes at the top part of the model, they will still be covered by my hand, that is why I did not create a lot of holes but rather put more at the bottom as it will look a lot nicer if the shadow comes out from the bottom and lights shine through the holes and reflect the pattern on the floor.

Fabrication of prototype

--Fabrication-Prototype 1 First of all, after unrolling the surfaces, most of the surfaces overlap each other, I have separated them into pieces and created 1cm thick tabs. Justification of using paper cutting for white papers and laser cutting for black cutting, reasons as below: â&#x20AC;˘ the natural process is related to the theme of contrast, being up and down, I want the colours of the strips to show the contrast as well. As the colour of the paper will turn brown after using the laser cutting, I have chosen the paper cutting for white papers. â&#x20AC;˘ the black papers have dash lines, time taken for cutting dash lines is faster in laser cutting than paper cutting.

--Fabrication-Prototype 1 ERROR

IMPROVEMENT

The side of each panel is not same (This is related to triangulate faces) length so that the strips cannot be Triangulate faces before unrolling stick together which is triangulate it when it is still a model but not strips The tabs are too obvious Make the thickness of the tabs to less than 0.5cm instead of 1cm Paper clips are too easy to be re- Use Fold Back Clip moved accidentally Time consuming as the problem of Cut, fold and stick the first two strips not continuing the make the model first so that it can be confirmed that is found after cutting, folding and it can be continued sticking all the individual strips The strips and holes and everything Re-scale the whole model before seem too big as the scale seems unrolling and making tabs not very accurate and has to be justified The surfaces of the model has Because of forgetting to flip it, it switched back to front and front to becomes the main reason why the back whole model has to be made again

After failing the prototype 1, each step will be double-checked more carefully so that no more wrong path is walked. I have gone back to the main concept which is the flying pattern of butterfly and added more surfaces to the model. Justification of the 3 spheres: â&#x20AC;˘ Ball bouncing curve is just like butterfly flying up â&#x20AC;˘ The higher the butterfly flies, the smaller the butterfly is, just like the sizes of the 3 spheres The whole model (include the biggest part) shows how a butterfly flaps its wings flying up to the sky

--Fabrication-Prototype 2 [idea generating]

--Fabrication-Prototype 2 [paneling]

The panels in sharp green colour represents that they have not been flipped

Because the two models are overlapped, I have used a line to cut through all the surfaces of the sphere and trimmed it. After that, I have added another strip of panels to connect them.

--Fabrication-Prototype 2 [unrolling and nesting]

Colour representation green: black purple: white

yellow: connection strip blue + red: black

purple+ light blue: white Using colours which have big contrast will minimize the error of identifying whether that strip should be in black or white.

orange: black light green: white

As the 3D pattern is designed in this way, I have gather two strips for one group and total as 15 horizontal/spiral groups of strips and 2 vertical strips as the opening and closing of the model. I tried to unroll it by group but does not work, end up I unroll one by one.

--Fabrication-Prototype 2 [creating tabs with grasshopper]

Grasshopper is a really good program to use as time has consumed a lot that I do not have to create tabs by myself. And also, the angle of each edge of the tabs is the same and therefore, it is a lot easier as the tabs will be stick fully while no sides or angles come out as if the thickness of the tabs are different. However, sometimes the lines connecting are not allocated to the right spot which I have to delete the lines and make the right ones to the right spot.

--Fabrication-Prototype 2 [unrolling and nesting]

During unrolling, this time is a lot easier than the last prototype as not many panels overlap each other, so that the strips do not need to be broken down into pieces.

--Fabrication-Prototype 2 [lighting effect]

After putting lights randomly on the model, I think I have to create a lighting pathway or system with reasons behind. Why am I putting the lights in that particular areas? What is the significance of that? Can I relate or connect back to my concept?

--Fabrication-Prototype 2 [lighting testing 1]

The three spheres are connected to each other and they have to be closed after putting the LED lights in, that is why I chose to make the electrical circuit for them first. I was considering whether to use the fishing lines or not to connect them together, however as even though I do not like the linking lines to be visible, the wires which are used to connect the LED have to be put, that is why wire is replaced the fishing lines.

--Fabrication-Prototype 2 [lighting testing 2] 1

Lights on the model on fig. 1 are hanged inside the model without touching the surfaces which creates a clearer pattern of shadow than the one which lights are attached to the side of the surface, making the shadow a bit messy or disperse.

As for the biggest part of the model, there were lots of consideration to be made as lighting test was done. 1. Whether lights will be blocked after my hand is going through the model 2. How many lights have to be used and what is the distribution of them 3. Whether to hang the lights or stick them to the surfaces of the panels I was going to put 16 lights on this big part of the model which 2 lines of lights are constructed with one left and one right because my hand will be put on top, if the lights are attached on the top, my hand will block all the lights. And the reason why it is 16 is because I am going to attach the lights on the upper black surface which lights will then shine through the holes and dash lines to the ground, making shadows with different shapes.

Precedent

M-City by Vladimir Plotkin and Roberto Meyer http://designsandprojects.com/m-city-byvladimir-plotkin-and-roberto-meyer/

Buddhism Temple | Miliy Design http://www.arch2o.com/buddhism-temple-miliy-design/

The outlooks of these two precedents, Buddhism Temple and M-City are very similar to my model design. It was good as I could have a look at these and consider where my lights should located in order to show this twisted curves. Both models are in spiral, but this temple is constructed as continuous curve in a strip but mine is constructed with numerous strips. It shows here that I can actually try to have my lights setting up in spiral so it can emphasize the twisting more for my model.

fInal prototype

As time taken for one prototype was very long, I did not manage to do a final model before the submission of module 3. This prototype will still look the same as the final one but the final one will be changed a little bit of the construction and design of the tabs and strips. Overall, I have used the parallel circuit to put the lights which means all the positive side is connected with 1 wire and negative side is connected with 1 wire. There are 16 lights in the biggest model with two 2 light strips, 8 each. 3 lights are put in the first sphere, 2 lights are put in the second one and lastly also 2 lights are attached in the last and smallest sphere. This model is just way too big than my expactation so my final model will be constructed again after resizing it.

fInal correction ERROR

IMPROVEMENT

As both FabLabâ&#x20AC;&#x2122;s and my problem, the 300gsm black laser cutting cards printed is mistakenly used instead of 200gsm The tabs are too thin

Make sure 200gsm is used otherwise the dash folding lines would not look nice and hard to fold and stick

After folding the dash lines and sticking two strips together, all the glues are very obvious and the cards cannot be fully sticked together The last two vertical strips are way too hard to stick which end up tabs are facing out The PVA stained left over after using too much The module turned out bigger than expected

Make the tabs as 0.5 for both white and black cards Use score lines instead of dash lines as lights will not travel through because there are two layers overlapping making it blocked 1. Making the tabs thicker 2. DO NOT make any vertical strips, instead, make all 15 strips as horizontal Try UHU but need extra care as well as there are glue thread will make the surface dirty resize the whole model before unrolling

Reflection from reading

The topic of this week’s lecture was Power of Making by Paul Loh. He started with a quote from Daniel Charny that drew my attention and from the quote, there are few words that were very memorable that I might not forget. “Making is something everyone can do.“ I always think during the making process, I can come up with many inspirational ideas for my design. It is a lot more powerful than just use a pen and a paper to generate ideas.

From this week’s reading, Brendan Macfarlane’s Making Ideas, I have gained more knowledge of generating ideas and from generating ideas to fabrication.

This week’s lecture improved my knowledge of how prototype should be and how important it is. Paul introduced different design processes to us in both certainty and uncertainty ways from assemblage to prototype. Testing and spatial type link together and physical prototype and digital prototype links together. They are all performance and effects separately. Furthermore, I consider the procedures of fabrication techniques are also very crucial for me in the future as to guide me through. First with generative or additive procedure, following by subtractive procedure and lastly with transformation procedure. It is good to keep following these procedures as when digital fabrication is on.

Nowadays, everything is used in digital, we use digital to express our ideas and belief and how it then influences us to think through a project and by using the project to influence others. Good way of presenting is another key to be influential. As the technology becoming more developed, digitalization becomes a more established, more essential technology advancement, it has been a trend now. This digital concept for virtual model is complicated yet powerful in the way of generating and expressing ideas.

Reflection from reading

This week’s lecture, the guest speaker, Stanislav Roudavskii introduces the idea of programming in design. Architecture is not only about construction building but also other sorts of area. Programming can assist us in solving complicated task when time is limited, it is a really quick and accurate system especially when designing is needed. It is very interesting how human set up programs to improve the quality of time in designing. I think of our fantastic FabLab as it helps me in cutting most of the strips of my model so I can save some times going through those assembly processes but instead, trying out more prototypes with good quality.

From this week’s reading, Personal Computers to Personal Fabrication, different computer-controlled cutting tools in fabrication, Subtraction, Addition and Building Models are introduced.

Before the lecture, I totally did not notice robots can actually be used more than we think in labour and human activities. They can totally do those work which we perceive as impossible. ‘Program or be programmed’

The idea of Equality fabrication is to deform one part around another one, ending up with the same amount of material in a new shape. It is introduced as a process without waste is because it is not both subtraction and addition fabrications which must produce waste. Ways to reduce waste while fabricating the model using card or laser cutter are: 1. Minimize the space between each unrolled piece 2. Do not throw the left-over papers after cutting the pieces out, use them efficiently 3. For the first 1 or 2 prototypes, use paper cutting instead of laser cutting as it is less costly and laser cutting is high power consumption

100 word response to the lecture Reflection from week 10 lecture As our week 10 and also our last lecture, the lecturer did an overview of the work process of this subject from the first week. The lecturer mentioned the working process on the right which I found very important to the working process for the future design project. By generating different angles of perspectives and voices, we are able to design some abstract work and together with all the presence of lectures and tutorials, the whole process will go a lot smoother. When the lecturer was introducing the material choices such as light, wind, sound and motion together with showing us video clips, I started thinking about how to express my model with perfect lights reflecting shadow with a meaning inside. In the clip, the shadow generated in the lighting test, movement and sound of people are presented. If Iâ&#x20AC;&#x2122;m sticking my lights on the upper black card paper, it might be seen through the holes by the audience which is too bright to shine. Therefore, long consideration time has to be prepared as lights are so important to this model, it has to be expressed in a lantern form, how could a lantern work without lights inside?

multiple perspectives multiple voices from abstrat to tangible learning by doing, comulative, reflective lectures: exposure to wider body of ideas & ambitions tutorials: testing out ideas in miniature, bounded exercise

REFlection

Over the past 4 weeks including the spring break, I have been focusing on this fabrication, this is the most rewarding moment as I can see my final model after all the 6 weeks of staying up late and running out of ideas. I still remembered the most depressing time when I printed out my first full-scale prototype and because the surfaces were overlapped to each other, I have to separate them out, unrolled them, using the laser cutting to print them and stick them back into one strip and that was the time when I found the model would not be able to be constructed as I forgot to flip the surfaces and also I did the triangular faces after unrolling but not before. That took me the whole first week of my spring break. Although this model turned out alright with the linking back to the concept and the effect of using black and white and the reason behind, I would still need to redesign and reconstruct the whole model in order to prove the reason behind and have a

neat and fix the mistakes such as the problem of the tabs and the thickness of the paper. The analysis and giving reasons parts in this module seems take up a very important place, it is a platform for us to explain the best we could to show how this model is transformed before leading to module 4. I donâ&#x20AC;&#x2122;t know it is because I have been with this model everyday for the last 4 weeks, I started found out the layout is too complicated and it feels like it is a bit messy. Unfortunately, I cannot redo the whole thing. I would if I had enough time. Anyway, this module is still my favourite one even though it is also the most time consuming one.

FROM IDEATION TO DESIGN

UNROLLING I decided to unroll my three sections- A, B and C and their matching edges separately.

The Extrusion- Section C surface and finned edges

The tubes- Sections A + B surfaces and finned edges

PRECEDENT:SPECTRA BY SHARON GOH

The designer was interested in the patterns geometric patterns formed in kaleidoscopes and what would happen when these were projected through lights. I found this related to my design because by panels are also triangular and can have the same effect, depending on where I place my light. She has placed her light in a central position and the shadows are symmetrical and radiate out from the center. Iâ&#x20AC;&#x2122;m not sure whether I want this effect or a more asymmetrical lighting effect.

PRECEDENT: COSMIC QUILT, THE PRINCIPALS

This project is an interactive installation made to respond to its environment and users by sensing movement and responding to it. Materials include paper, aluminium, According to The Principals, "The project aims to answer the question 'What if architecture responded to our presence?' This project is a realization of our ultimate ambition, which is to design spaces and objects that expand upon our understanding of the built realm without abandoning its history.â&#x20AC;&#x153; The way that the lighting creates an overlapping effect is interesting and can influence my placement of lights. For example, should I place it in fold to create the layering effect to create this effect or on a smooth part where there is no overlaying of shadows?

UNROLLING (PROTOTYPE)

Colour Coded Section A

My method of unrolling sections A + B included grouping a seam e.g. A01, before grouping ring around the seam before colour coding and labelling. Below is an example of the unrolling method I used for the prototype. However, this method was unsuccessful and a different method was used.

Colour Coding from end

The solution? Each strip from strips from C1 to C6 and C20 were renamed strips J- I ( these were the only ones I wanted to have the finned edge effect) They were split into their constituent triangles and labelled. Large tabs (3cm) that were90degrees from the edge were created on grasshopper. The idea was to construct these strips with the tabs on the outside to create a â&#x20AC;&#x153;finned edges effectâ&#x20AC;?. To the left is an example of how a strip was split into triangles and labelled.

To construct the strip, the numbers on the labels were matched up by looking at the digital file (above)

Triangles of Section C- Ivory Card White- 200gsm, Scale: 1:32

NESTING In total there were 6 sheets of A2 200gsm ivory card used. I chose to use this type of card because it was sturdy enough to give the lantern form, but thin enough to get the lighting effect I wanted. It was also a good thickness to glue together to create a curved effect.

Ivory Card White- 200gsm, Sections A, B and C unrolled, Scale: 1:32

FABRICATION Need: Cutting mat, Bulldog clips, adhesives (PVA glue, superglue, needle and thread, fishing wire), Pencil, Stanley knife, Metal ruler, Fablab file

Construction of Sections A + B- using bulldog clips to hold the pieces together while the glue dries

Construction of Section C- Pieces were cut out and glued with edges facing upwards, on the exterior. All the triangles in a strip were joined together before the strips too were joined together, all held by bulldog clips. The â&#x20AC;&#x153;finned edgesâ&#x20AC;? were then cut to desired width.

LIGHTING Two simple parallel circuits were made. I chose to wire the lights in parallel so there would be equal voltage across each light, making them project the same light intensity. These were inserted into the lanterns during construction .

Materials: LED lights x 8, Battery pack/ switch x 2, 4 x AAA batteries, Wire (white) approx 5m, Stanley knife, Scissors, Cutting mat, Ruler, Masking tape The wire was cut to appropriate lengths before the plastic was shaved off the ends to expose the copper wires. These were joined in a parallel circuit with LED lights and secured with masking tape.

TECHNICAL PROBLEMS 1. Problems with Fablab file Some sections where the line was meant to be etched was cut instead. This was fixed by gluing a strip of card on the back to join these together.

2. Some sections did not join together properly. This occurred using when making the first prototype, so I unrolled the sections using a different method or I hand-cut pieces to close the holes

3. It was very difficult to join some of the smaller, fiddly parts together. So I used superglue and/or fishing wire and thread to hold the smaller pieces together.

FINAL PROTOTYPE

REFLECTION In the fabrication module, I learnt two important things: (1), that your final design is highly dependent on the tools and materials you use and (2), that no matter how much technology develops, manual hands-on construction is essential for a designer. â&#x20AC;&#x153;The tools are an undeniable part of the productâ&#x20AC;? In my case, the tools were the rhino program, the fablab laser and card cutters, stanley knife and scissors. A limitation was the time it took for my file to be cut, and the effects of the different machines. For example, the laser cutter produced burnt edges, and this was not a desirable effect in my case. This is why I decided to make two prototypes in this module- because the pieces with burnt edges did not look aesthetically pleasing with those of the card cutter. On the other hand, the card cutter was much slower. The materials included the card and adhesives such as glue, superglue, fishing wire and thread. The properties of the materials such as the weight, layers, ability to stick limit what can and cannot be physically made. The smaller pieces were especially hard to connect and superglue was used for this. However, the superglue is very inaccurate, leaving you no room for error. The paper was difficult to bend and twist and only planar sections worked and looked clean. The digital model could not be reproduced exactly because of this. For my final prototype I think I will make my pieces bigger, use the card cutter and a stronger glue to get the desirable effect. I also learnt that no matter how much work a machine or technology can do for you, the process of fabrication is still very labour intensive. Technology just speeds up the process, and because of this, more and more possibilities are available to us. I was fascinated by the different digital technologies such as the water cutter and injection moulding. These can influence the project by opening new areas of exploration, new possibilities and speeding up the process, allowing more time for more design iterations. However, at the end of the day, we must still construct the model ourselves, so we can never be fully dependent on technology, no matter how helpful it may be.

READINGS AND LECTURE RESPONSES Macfarlane (2005): Macfarlane talks about how about during the process of fabrication, concepts change and you must go back and forth between the conventional method and digital method. Use either or and both. New ideas emerge and these can be incorporated into the design. I agree with his idea of “making ideas” and how using a different tool e.g. digital technologies can help open our eyes up to new possibilities. My concepts evolved and changed during construction as I had to design around some problems such as pieces not fitting together. In a virtual model it is difficult to get the feel of the structural properties because you can’t feel it in your hands, so that is a limitation of digital technology. Also, alterations were made to the physical model to look better, or when the virtual model did not translate exactly onto the paper. In MacFarlane’s projects, he used “events as a generator of form” The “event” is a problem that arises which the architects must respond to and includes in the brief. For example, the event that occurred in the renovation of the Maison T house was the growing up of the boys in the family and their needs and wants, as well as the existing roof where the extension was planned. These factors dictated the form of the final product- which conformed to the limitations of the existing roof, the views, privacy and space the boys wanted. Gershefeld (2005) In Gershenfeld’s reading, he introduces “equality fabrication” as a process without waste, and laser cutting/card cutting is a “subtractive” method which is not as efficient. In order to maximise the efficiency, the pieces were nested in a way to reduce the number of pieces of card needed. Furthermore, hand pieces were cut from the scraps. Other ways of reducing the waste could be to incorporate scraps into the lantern or to make another, smaller lantern out of the scraps. When he mentions the “traditional division of labour”, he is talking about the roles of humans and machines and how machines are now crossing over into what the traditional roles of humans such as building and manufacturing. Digital design and fabrication challenges this notion by becoming increasingly similar to humans in terms of their roles in building and manufacturing. These fabrication techniques can reduce the volume of work a human has to do in order to get the same outcome- example- prefabricated houses. On the other hand, these technologies also open up new possibilities that are not possible using traditional methods.

Lecture 7: Unfolding This lecture informed us of the “how-to’s” of using fablab. It was very useful and servd as a practical step by step guide as to how I would commence unrolling and sending to fablab. When unrolling my model I incorporated all the steps into my process. I was also introduced to Grasshopper and amazed by how easy and quick it was to use. I also started to think about how I would split my model up into sections for construction. Lecture 8: Paul Loh/ Power of Making “Making is the most powerful way of solving problems.” Paul gave a lecture on the history of construction and where some of these digital technologies originated. Most come from the automobile/ airplane construction industries, and I suppose this shows how important it is to work with and look for inspiration from other fields of study. It was fascinating to learn how The making process is a learning process- we learn and think at the same time we make. We can test the aesthetics and functions of a model. I am beginning to see the importance of prototypes and how this design process is really designing back and forth physically and virtually. Lecture 9: Augmented Spaces/ Stanislav Roudavski Stanislav talked about how technology does not limit our creations, but is instead, our knowledge of the programme that limits our creativity. He highlighted how understanding is backwards- we must understand how the software works in order to know how to use it. He challenged the idea of “function dictates form” with the alternative, “form follows software.” These are both true, whilst the concept “function dictates form” gives the design a purpose, it does not necessarily have to dictate the form- the design is limited by what the software can do. This was a good reminder of the brief to make a lantern that fits on the body and a personal reflection of whether I was fulfilling this brief. He also showed us some examples that were quite inspiring, such as the wall building robots and an interactive structure, forms that could not be possible without digital technology.

MODULE ONE PLASTICINE MODEL

Design Division This final design from module 1 is a compilled and multilayered outcome from the whole ideation process. I have developed a design that connotes the moon as mysterious yet supernatural as well as a multi-scaled matter.

MODULE TWO DIGITAL MODEL

Digitalised This final design from module 2 is an extension of the first module. The form shifted from being a solid component into a hollow matter that consist of a network of panels that are sporadically distributed on the body. This replecates the event of crater formation whilst focus is given on the orientation, size, shape and distribution.

DIGITISATION LAYERING Seperation This was an attempt to divide model into different layers vertically to ease of unfolding process.Horizontal splitting should provide better structural support of the paper. The seperation however proved to be redudundant, messy, and lacked order. Also, the difference in connection created overlaping surfaces when unfolding.

DIGITISATION ALTERNATIVE LAYERING Reapproached layering process After seeking advice, I was told that with my design, it would be better to create horizontal rings. I therefore seperated them into large rings and then segmenting each ring into smaller easy to understand pieces. Clarity was enhanced by removing the visibility of isocurves. This enabled me to see the digital defects of that arise prior to unrolling the surfaces.

DIGITISATION STRUCTURAL BASE

Repairs With a better unfolding order, the process of layering seem to have revealed several design flaws. Panels that are too tight and disporpotionate were replaced with flat faces. Problems arise at the surface joints and some disorientated fold lines. The solution was simply to reconnect them at their end points and changing the diagonal

DEVELOPMENT BASIC PANELING

Moving Forward Upon a satisfactory unrolling, I joined the surfaces and started to create tabs and edit dodgy panel structues.

DEVELOPMENT TABS Shortcut Using available grasshopper templates, I have craeted the tabs and score lines for the unfolding process. Panels were split into two regions where the bottom half require smaller tabs to fit adequately. Grasshopper tab settings for layers A to I

Since I had 66 faces, I reevaluated the plugin function. I used the template for paper cutter and simply changed the line type into â&#x20AC;&#x2DC;dashedâ&#x20AC;&#x2122; to cater for my laser cutting process that I decided to use. Along the way, I deleted, replaced and adjusted some cut and score lines to ensure that the fabrication of my first prototype is smooth and easy.

Grasshopper tab settings for layers J to N

After grasshopper automation of tabs and score lines, I needed to do some final tweaking for overlapping tabs, changing line types, cut outs and to removeunnecessary lines.

FABRICATION CUTTING TEMPLATE

The Test From Module 2 prototyping, I have decided to use 220gsm black and white cards because they seem to have inherent strength and allows a generous amount of light penetration. The first attempt to create a template was simply dropping the panels into the frame of my material. I felt that this is poor material efficiency. I therefore rearranged and rotated the panels to create minimal paper waste. This does not create confusion when cutting because panels are individually labeled and the joining tabs are fairly systematic. With this prototype, I mirrored image half of the cards to see what would the panels look like if I used the back surface of the laser cut outs. I would like to use the burn marks to my advantage.

PROTOTYPING UNFOLDING

Second Prototyping After implementing some drastic simplifications and reordering, I decided I have to test the physical possibility of the design. The unrolled panels fold up supposedly fold up into a ring from the model. However, the distribution seemed raher complicated to follow. Therefore, for future references, I decided to fabricate each panel individually with folding reference to the base panels.

PROTOTYPE ONE DEFECTS Physical Deformaties Despite being quite aesthetically pleasing, the prototype revealed several design and material flaws. Corrections were noted on my journal and the CAD file was revisited and the lines were manually fixed. White surfaces illuminate while black surfaces merely chanel light out. With a physical model at hand, I could easily rearrange the colour of each panel on the digital file. Above all, the most critical issue I discovered was the flimsy and unstable form this first full scale prototype has. 2: Flaw with the dashed line system

STRUCTURAL DEVELOPMENT RIBS

Skeleton One option Iâ&#x20AC;&#x2122;ve considered was to create ribs for thte paper model using mout board. However, this Idea revealed flaws; uneven non-planar surfaces, overlapping ribs, irregular symmetry, and difficult to integrate with panels.

Lee Kum Kee Lantern Wonderland 2012 Design â&#x20AC;&#x153;Golden Moonâ&#x20AC;? by Kristof Crolla & Adam Fingrut 21 metres in diameter and 18 metres in height. It is constructed with a steel frame, bamboo, stretch fabric, LED lights and suspended lanterns. A light-weight steel geodesic dome forms its primary structure. Using traditional bamboo scaffolding techniques, bamboo is bent around the geodesic dome to form the secondary structure. This design impresses me with its scale and structural strength. I extracted the concept of how they position central lighting at the centre instead of on the inner surfaces, how they used tensile materials to offer a better physical support and how their material choice allows the illumination of light. Upon moving forward, I have decided to create a core system that could both house my light circuit and give panel support.

AMENDMENTS REVERSE ENGINEERING Weighing Options I have considered several options to resolve the structural fragility. With a few attempts on each idea, I decided to proceed by creating an outlined offset frame in intervals of two rings. This integrates the concept of portal frames as well as providing a space to attach my light circuit.

Current Model exhibits light beautifully but is structurally weak

1: PVC or Arcylic inner layer

2: Tab networking

3: custom hand made supporting light box

4: rings that outline panel grids

AMENDMENTS PROBLEM ROOTS After Due Consideration A major problem to fix was the line type, especially the presence of score lines at the end joints. It potentially causes the card to tear apart and weakens the structure. Having a fair amount of confusion with the available Grasshopper templates, I decided to consult tutors for a better tabbing solution. Although changing the definitions did not work, we resolved the issue by creating a custom pattern, â&#x20AC;&#x2DC;Special Dashedâ&#x20AC;&#x2122;.

FABRICATION SECOND ATTEMPT

Materiality With the same process as the prototype, I had a second set of laser cut panels with amended properties as mentioned before. Also, I shifted to 300gsm cards for better independent support. This is a compromise between structural and material properties. In addition, I enlarged the model by a scale of 1.3 for easier construction, especially at smaller panels.

FABRICATION PROCESS

Moving Forward With satisfactory ammendments, I proceed with the assembly process in the same way as before. The assembly process halted midway to allow the installation of structural support and lighting Wcircuits.

LIGHTING CIRCUIT Current Risks I decided to create my own electrical circuit. The bare minimum 3V supply only lits the LEDs dimly. Testing the lights to their maximum revealed that: Vmax=9V Therefore, to maximise the Power of the 9V battery, it is best to install LEDs in parallel pairs whereby each LED will recieve 4.5V (refer circuit diagram).

By Using Ohmâ&#x20AC;&#x2122;s Law (V=IR), I calculated, for LEDs to shine brighter, current has to increase. For the circuit to be safe, I would require a 10Ohms resistor.

FINAL MODEL

CRITICAL ANALYSIS I believe that Module Three has been the epitome of Virtual Environments. It is the bridge that connects the physical realm and the digital dimension together to form a tangible design. It has been much fun and excitement to manipulate my conceptual ideas. Much my process has resemblance with Macfarlane’s (2005) Restaurant Georges in Pompidou centre. Their iterations, given their technological limitation at that time emphasises the importance of making a prototype as they analyse the shape, support and material interaction with light. With my design, the prototype enabled me to critique and decide firsthand the material distribution and strength. I discovered that thicker card has better inherent strength but less sensitive towards light. Also, black card is opaque whilst white card not only emits light but glows itself. I applied these properties to the advantage of my original moon crater elemental concept. Amendments were done through ‘reverse engineering’, by modifying the internal design to produce the final outcome (Lecture 9). The process of unrolling has been confusing and chaotic to begin with. Through, consultation and recommendations, the implementation of this phase becomes organised and understandable. When people speak, we are taught to listen. When people read, we are taught to write. And when computer programs were invented, we are taught to use it. Instead of using technology, many a time we are used by it (Lecture 9). This theory resonated through the unfolding of panels. It has come to my realisation that CAD programs are designed to ease and hasten the design process, not to stumble designers. Hence, I approached the overlapping panel problem with a keen eye to look for the possible misfits and flaws. It is fruitful to see how simply reordering the diagonal vertices and connecting the end points solved the problem. Further, I am also reminded that I work in both the digital and the physical medium. Where problems are seemingly unsolvable on screen, I could leave it aside and create a physical prototype. The physical assembly simply accentuates the flaws that were unspotted on the digital model. Modifications are then later included to the file. Knowing my tools reduces challenges and thus increases efficiency. Gerohenfeld (2005) addresses the way Ghery (draws no straight lines) and Larry (keep to the basics) move forward and convey their ideas. They have an ‘equality fabrication’ that resembles the assembly of proteins. Every intricate detail is considered. This prompted me to consider minor details that shape my physical model, from the possibility of using minimal material and type of machine (laser or card cutter) to the definition of my score line types. These pointers are not only cost efficient but also adds to the high quality design and fabrication as well as longevity of the model. Lighting is a vital component of a lantern. After being through many design processes, it is natural to forget the importance of a small design portion. In Lecture 8, Loh informs us that our lanterns are objects that comprises of an assembly of individual components. They are always adjustable. I did not include a circuit in my full scale prototype. Only moments after the last tab is glued did I realise that clipping LEDs on 3V cells are simply inconvenient, risky and unacceptable. Motivated to be a ‘professional’ worker, I persevered and find ways through it. I revisited my former science knowledge and created a technical circuit supported with comprehensive calculations and conceptual understanding. This moment resonates the importance of knowledge; learn as much as possible and remember them. Overall, it is undeniable that the course stimulates students to learn techniques to apply on a larger scale future design (Lecture 9). This module highlights the importance of testing, analysing, reflecting and solving problems to produce the best possible outcome.
