DIGITAL DESIGN + FABRICATION SM1, 2016 M3 JOURNAL - Skin & Bone Jack Collings/Yuebing Xiao 756547/ 751795 Lyle Group #11

Introduction
From the progression of Module 2 and exploring such precedences as Dunescapes by Shop architecture and the Kinetic Wall by Barkow Leibinger, our design shaped and eventuated to this movable structure. The skin and bone principle structured our design and we formed an overlay and repetitve geometry to create a moving flow of this dynamic design. There was still many issues with movement and the overall shaping of the design that had to be refined during this module.

Design development
The Alteration of the structure needed to be adressed and a desired shape had to be formed before we could continue with the fabrication. After methodically arranging shapes and laying elastic supports we found a reliable and workable arrangement.

Reading Response Wk 6 Architecture in the Digital Age - Design + Manufacturing/ Branko Kolarevic, Spon Press, London c2003 Briefly outline the various digital fabrication processes. Explain how you use digital fabrication in your design?
The new form of the digital uprising is presented by Branko, as a new reformation of architecture’s conceptualization or methodology approach in architectural design. Stating that modern Architecture is in essence ‘born out digitally’ as the limitations of completing a design digitally are explored and presented as a limitation of digital formalities. 3-axis milling machine, image by Kolarevic.

The digital fabrication of digital to physical has created the complex geometries that wouldn’t normally stem form drawings, as NURB curves and surfaces. The processes of which include, two dimensional and subtractive fabrications. This process was used in module 3 with the two-dimensional laser cutting involving a two-axis motion over the specified material sheeting from the digital software of rhino- which was more limited to our skill level then the programs limitation.
Reading applied to design
How does the fabrication process and strategy effect your second skin project?
The fabrication method of the two dimensional axial printing limited but also drove our design to be fabricated on a two dimensional plane. • Rhinosoftware, shaped and derived how we could form our final design with the limitations of our knowledge base and skill of the program • Material, restraints were seen as availibility and acces to materials in both the fablab and fittings from hardware stores. • costing, set a limit to exploration of physical modeling and the final finish of the design outcome as highly expense materials is not feasible for the project. • time, coming into constraint from the digital to fabrication process of the physical cutting and other limitation brought forward from the use of digital programs- such as crashing of software.

Reading Response Wk 7 Digital Fabrications: architectural + material techniques/Lisa Iwamoto. New York: Princeton Architectural Press c2009
Describe one aspect of the recent shift in the use of digital technology from design to fabrication?
For new developing, it is because the original model is loose and not stable that using material of rubber bands is an attempts to control the loose structure. The qualities of rubber bands are not only flexible but also controlling the movement. Therefore, the model became more stable but still moveable.

Referencing from the lectures and readings, what is the implication of digital fabrication on your design ?
According to this reading, the form used sectioning as digital technology with precedent of Dunescape Project (shown right above).

The new model still followed the geometric shape of the origin. Specifically, the model is built by a series parallel, stacked dimentional MDF with rules. For makin this model much more stable and comfortable, we changed the edge of elements into round cap and constructed the whole form with tight connection between layers.

Prototype development
During module 3 the main sources needing to be developed and modified was the overal geometry of the designed structure. Trialling of elastric supports held the form of the ‘bone’ of this structure. Tested was a multitude of failing results that needed to be modifyed and arranged sytematuically unitl the final configuration was achieved.
10
The elastics hold the structures shape together, when applying the force onto the joints it moves with force making the structure move with the needs of sleep but still reconfigures top the original shape after the force has been applied and removed.
Through trial this arragement was derived to hold the shape of the structure. Allowing the elastic to move by stretching with an applied pressure onto the structure, making the model both more functional in comfort and adding an aesthetical quality of the moving formation.
11
Prototype optimisation
After the formation of the desired geometry was established, the laying of the movement between elements was used. Arraying the layers of MDF presents an interesting dynamic function as the system moves in different ways with the differing forces placed onto the design. The elastics holding this shape as presented to the right and thus acted as a base for the design of the overall integrity
12
Through prototype testing the material usage became eviedent to display the desired effect of the design and seemed practical enough in terms of cost and production methods as construction involved the use of nuts and bolts and threading of elastic. The material behaviour of which is used to gain the desired effects are due to the shaping and arrangement of the individual pieces and the tension forces of the elastic and the skin fabric used iun the final model.
13
Prototype optimisation
The refinement of the model from the prototype seen changes that improved the practicality and the function of the model while inhancing the asthetic values and the models visual quailities in presenting the movement of the design. Changes include the shortening od elements, rounding the edges of courners, elstaic supports to hold geometric form and alteration of bolt size all presented in the final fabrication. Prototype

Final fabrication of Model
The material was Laser cut and constructed from 3mm MDF.
15
Prototype optimisation
Design optimisation due to Material usage, came together as the form was distinguished. The materials that play into holding the structure into shape and positioning can be seen as the elastics, the streachy fabric and the pin joints of the nuts and bolts.
16
The use of the material for the skin of the structure is an elastic fabric that presents the movement of the bone under the skin, which is presented with the tension of the connection joints and depicts the movement of the design.
