Week Three

Reading: Kolerevic B. 2003. Architecture in the Digital Age

Kolerevic described three fundamental type of fabrication techniques in the reading. Outline the three techniques and discuss the potential of Computer Numeric Controlled fabrication with parametric modelling.

The three fundamental fabrication techniques mentioned include 2D Fabrication (CNC laser cutting), the most commonly used fabrication technique; Subtractive Fabrication which involves the removal of a certain amount of material volume from another solid; and Formative Fabrication which include the use of mechanical forces, heat and steam.

In regards to the potential of CNC fabrication with parametric modelling, it is easy to mass produce and create many different iterations of the same object quickly (AKA rapid prototyping), as well as the fact that the digital world is ‘limitless’ and less restrictive than using pencil and paper, thus designers can create new abstract forms which are difficult to represent on paper. It also creates a correlation between representation and production, in that before this technology, architects could only make what they could draw.

Week Three

Surface Creation

The script of the final surface (shown in the top right corner) is shown above. I chose these surfaces to place my panels and base the interior waffle around as although they were more simple surfaces, It allowed for more iterations/creativity with the 3D panels without making the design too complex to construct. It was also able to have a waffle structure underneath it, whilst some other iterations were too curved/complex to have a structure underneath. The other iterations I experimented with (also shown on the right side) were either just all 2D or 3D panels, however for the final iteration I combined the 2 to add more interest in the design as well as height difference and texture.

I mainly used the sliders linked to the Item and Divide components to create surfaces that I thought were interesting, then baked them out.

Week Four Panels & Waffle

Both panels follow a gradient type design (as shown in my matrix diagram) as there is a higher density of 3D panels at opposite points of both surfaces, however there is an even amount of 2D and 3D panels on each surface. Both surfaces also follow a wave like form, allowing shadows to form and light to disperse in an interesting way.

Alike the surfaces, the waffle structure also follows a wave like structure and is self-supporting (can stand up on its own). The curved form is juxtaposed with the sharp geometric design of the 2D and 3D panels.

Week Four

Laser Cutting

4 For ease of construction, I created a

1

grid of numbers and letters on each of my surfaces, in which surface 1 was letters A-E, numbers 1-5 and surface 2 was F-J, numbers 6-10. As I was unrolling the panels in Rhino, I labelled them using this system. (see annotation 1)

3

With my 3D panels being a more complex shape, I had to unroll each of those panels into 3 sections, as shown by annotation 2 in the nesting image. However, I was still able to unroll 2 or 3 of these shapes at the same time, as shown in annotation 3.

The 2d panels on the other had, were very simple to unroll, as ex-

5

pected. I also labeled these as per annotation 4.

I used this same system for the waffle structure, labelling the inner sections from 1-9 (1 being the lowest) and each of the sticks were labelled from 1-19 also for ease of construction (as shown in annotation 5).

When placing the line work onto the template, I made sure to nest each element close together to ensure no material wastage and a quicker job.

Week Five

It was a challenge to experiment and try and create a shape that was not a sphere in grasshopper, however I decided to experiment with a cone and cylinder shape (as shown in script above), and then discovered weaverbird, where I was able to create more interesting and geometric shapes, such as the hexagonal based pyramid, which I chose as my final design. This shape also created more interesting boolean sections compared to the others, as a lot of the cone and spherical sections were unable to be printed as areas between shapes were too thin or each ‘layer’ of shapes was not joined together.

Week Five

Isometric

The iteration I chose has both middle and outer elements, in that whilst the exterior is remaining flat, the interior is engaging and has many different sized forms. Compared to other iterations, The model was also easily 3D-printable, as since the back surface is mostly flat, I placed that on the base to reduce print time and support structure.

In terms of porosity and permeability, the shapes created via boolean difference create cave like spaces allowing light to bounce off the geometric surfaces, creating an engaging interior and shadows. Compared to the interior, minimal ares of the internal geometry extrude outside the cube form, thus the exterior edge remains largely intact.

Design Matrix 1:5

The triangular 3D forms gradient from a high density in the top right corner to lower density in the bottom left corner.

This effect is mirrored in the opposite surface to create interest through variation in 2D and 3D panels.

Task 01 Matrix For Task 1, I chose to develop 2.4, as I thought the gradient effect of the 2D and 3D panels created interest and variation in the design, as well as the light through the 2D panel cut outs coupled with the shadows from the 3D panels creating an interesting effect, as well as the variation in height throughout the design.

Cut outs on 2D faces allow light to easily enter the interior structure

Design Matrix 1:5

As the pyramid geometry is not visible with the cube as a whole, the inside form, once trimmed, is highly intricate Large amounts of the geometry intersected with the top face of the cube, creating open space allowing the inside of the form to be shown

Task 02 Matrix I chose to develop 3.4 as the shape I chose was unique and was able to be 3D printed, as there was no small parts to the design as well as each layer being joined by a significant amount of material. Although the exterior looked simple, once I trimmed the cube it revealed the geometric interior, which not only had design elements on the sides of the interior, but also the middle creating depth in the final iteration chosen, as shown on the right.

The shapes created via. boolean difference create cave-like spaces and allow light to bounce off the geometric surfaces, creating an engaging interior

Minimal areas of the interior geometry touch the outside cube form, thus the exterior remains largely intact

The section cut chosen is the most intriguing part of the boolean cut as there is still some solids present in the middle, creating depth in the design

3D and 2D Panel Creation The above is the script of my surface’s 2D and 3D panel creation. The script remained largely the same from the workshop, however I added different surfaces and breps into the scripts to create the surfaces.

On the side the 2 3D panels and 2D panel designs plugged into the script are shown.

Appendix

Process: Module 2.1 - Surface and Waffle Structure The first surface I experimented with, the 2D and 3D panels worked successfully, however once both surfaces were plugged into the grasshopper script to create the waffle structure it was not successful. From this, I had to modify the surface to find one that worked successfully, thus creating my final design.

First experiment with 3D panels:

First experiment with surfaces: too complex as

Grasshopper baked out surface

they overlapped each other!

First 2 surfaces chosen: grasshopper surfaces baked out

Appendix

Process: Module 2.2 - Solid and Void Boolean Section Creation Once the shapes were boolean differenced from the cube, the form was cut in half using the polyline and midpoints.

From this, the section was cut in half again to create quarters, then cut diagonally, to create the 1/8 required to 3D print.

Thickness Analysis

Prior to 3D printing, the show

As shown above, the model was sufficiently thick enough to print, as there are only minimal red (1mm) sections.

edges command in Rhino was used, and there was no naked/ unjoined edges, thus the model could be successfully 3D printed.

The final iteration, later sent into 3D print.
