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. (150 words max)

1. Two Dimensional Fabrication: Fabrciation techonology that involves moving cutting head and/or moving bed along only 2 axis over the material sheet. Various cutting heads are listed as plasma-arc cutting. water jets cutting, and laser cutting. Decision of which cutting head used depends on the thickness of the cut material. 2. Subtractive Fabrication: Fabrciation technology that removes certain amount of volume from solids in order to create the designed form. To differentiate from two dimensional fabrication, one more axis (z axis) is added to the drill bits so that the drill can be lifted up or lowered down to remove volume of material. 3. Additive Fabrication: The general principle shared by various additive fabrication techonologies is that the model is ‘sliced into twodimensional layers’, and each layer is going to be added on the previous one by the manufacturing machine. Parametric modelling allows designers to produce dlexible digital models with countless iterations efficiently and conveniently. and physical model can seamlessly be fabricated using CNC fabrication technologies. Therefore the potential of parametric modelling is to offer rich opportunities to explore new geometry, products, and even space.

Surface Creation

Scipting the surfaces iterations, the interaction between two surfaces and the stability of the form comes to concern. The first itration is the basic form which the later surfaces developed on, it shapes the tendency of the surface from narrow opening at the front to the larger opening behind. The seond one is exploring the curvy shape of the surface while the third iteration develops more. However, beacause of the panels added on physically might not have the capability to form the shape completrly, a more moderate curve is chosen as the latest version.

Week Four Panels & Waffle

The 2D panels on the left surface applies gradation of the size of the opening so that the shadow can serve as a guide for people in the space. The 3D panels on the right have the gradtion over the complexity of the geometry, from one single pyramid, to double pyramids to the pictureframed panels at the end. They all together serve to suggest the larger open space behind. For both 3D and 2D panels, they are designed to be developable or foldable when fabricating.

The waffle sructure of the digital model unstable and seems to collapse due to the lack of balance at the front. When fabricating the physical model, the waffle structure stays stable suprisingly. However, it is still difficult to stick the 3D panels on to the waffle structure.

Week Four

Laser Cutting

Comment on the process of creating a Laser Cut file for your model. what is the constrains and highlight what you have learnt. The connected triangular surfaces are 3D panels while the strip-like shape are 2D panels. The surfaces on the right are all made for the walffle structure. One problem when it is finished is that the surfaces with black triangles inside have the burned mark on them which looks dirty. It can be solved by changing them on the etching line and manully cut them off as for the future advice.

When scripting for the boolean solids in side, i realize it is more controllable to adjust the poistion, shape and the size of the solids i’d like to boolean in grasshopper than doing them is rhino. First iteration is using platonic octahedron, second using extended octahedron by morph, third using weaverbird’s dipyramid with top point indicated, while the fourth one applying reverse attractor point.

Week Five

Isometric

Insert a brief description of your isometric here. Comment on the process of choosing which iteration to develop and 3D Print. What are some of the spacial qualities of your model? How does it address porosity and permeability?

This iso metric is fomed by boolean out many dipyramids from the traingular column to explore the spaces created inside. Iteration 4 is chosed to bedeveloped as it reinforces the direction of the space and various size of the space. The spatial relationship of adjacency is islllustrated. Each space can be clearly defiened, and to respond in its own way, to have their own functional requirement. Large openings provide view to the outdoors, to estabilish the relationship between a rooms and its surrondings visually. The opening expands from small trapezoid to a large rectangle, which lighten the room up. In addition, the shape of the view also changes to encourage movement within the space. The scene created can dominate the space by the openings and provide a backgroud for the activities within it. A small round opening can frame a close-up detail of the view outside, connecting one space to another. Porosity and Permeability can be addressed through the fact the the void space are all opened up for air ventilation and direct sun light through.

Week Six Task 01

Task 01 Matrix For the lofts, 1.4 is chose to be developed as the it forms the shape from a small triangular entrance to a larger space. For the Panelling grid, the effort wants to be achieved is suggestive and directional, so that the attractor points are put at the top corner of each surface. The later panel 3.4 reinforces the idea of encourge people to move through the space by arranging the panels in gradation.

Week Six Task 02

Task 02 Matrix Grid is manipulated to be like 1.4 in order to achieve an orientation while the distribution of the geometry reinforces the idea (2.4). Through the Dipyramid transformation, the feeling of orientation and direction is emphasized which contributes to the reason choosing dipyramid.

PROBLEMS

3D Panels with Wrong direction

Process

3D panels printed

3D Panels with right direction (all manually cut)

3D panles made by laser cutter are manullay fabricated on friday night of week 6. however, when all the panels are sticked together and triying to connect the waffle structure, it is found out that the surface is totally fliped accoding to the digital model. Since the assignment is going to due on the following monday, it is decided to print all the 3D panels and manually cut all of them, even though the the quality is not as good as laser cut, the experience is still valuable and needed to be learnt in the future.

Appendix Process

For the dipyramids transformation with top point, various position of the top point is also experimented but had ahieved with a less satisfied visual effect.

12


Appendix

Process

For both 2D Panels and 3D Panels, Iterations are made and individual panels are exchanged to achieve the gradation effect.

Primitive Analysis Process

Primitive threshold diagram and how people occupying the space is analyzed. For the left model, the font red creates a lowered and compressed threshold and the blue one behind creates a large blue threshold which suggests open space

How people (blue column) can occupy the space is snalyzed. It is found that people can circularte the space horizontally but has limitation for vertical circulation. Also, when people move from the right side of the surface to lhe left side, they would feel compressed but attain more visual privacy
