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)

In the reading, Kolerevic mainly talk about 3 different type of fabrication techniques. First is subtractive fabrication, and this technique is to reduce a particular volume from a kind of materials and solid by a series of reductive process including electronically, chemically qne mechanically. The second technique is additive fabrication, and it is about making 3D model by using CNC machinery and adding materials. The thrid is formative fabrication, and it is mainly about hesting and steaming a material to form it into a mold. Computer Numeric Controlled fabrication with parametric modelling can be a good and effecient way to create and build a accurate complex model compared with manual work. Moreover, it is also can quickly and effectively to adjust and change the relative data which can save time.

Week Three

Surface Creation

This is the process of scripting and iterating my surfaces. Right hand is the scripting surface in rhino, and those surfaces on left hand are the process of iterating my surface. In this process, I try to change and adjust the shape and angle of the surface in order to get a good visual effect in final

Week Four Panels & Waffle

+

The Panelling of my two surfaces choose two different pattern, one is 2D pattern that can make a contrast with 3D pattern on another side. The common part of the two sides is the hollowing out triangles.

The twist degree of waffle structure my is quite big that can make a different visual effect

Week Four

Laser Cutting

Those are part of my waffle structure and plannel patterns laser cut. I use 20mm tabs for my plannel patterns, since big tab is esay for me to make the pattern.

Week Five

Right hand is the process of scripting boolean form. The left side is my designing boolean form. I try to use 3 different geometries- sphere, hexahedron and octahedron, and finally decide using octagon geometry. In the bottom-right, I adpot morph scale for octagon(right) and reverse attractor(left).

Week Five

Isometric

For the develop of my 3D print, I perfer to create a model that is simple and have regular shapes, since this kind of model can always be made at a glance. I have try many different geometries, but some of geometries exterior is quite complex, the modles exterior become irregular and mess after booleandifferent in rhino. Finally, I choose octahedron, since its appearence is regular tetragon after booleandifferent, and the interior structure of octahedron has sense of space and sense of depth. For the overall appearance of this model, I want make interest shape, so I make a “L� shape boolean geometry. About the spacial qualities of my model, my 3D print model has a penetrating nature. The inside structure of my model is connect, and every exterior patterns can be open space.

Task 01 Matrix My final surface decision is 1.1 and 2.4 and others are test for my decision. For the panelling, the final decisionis 3.4 which is the combination of 3.1 and 3.2, and befor that I print the unrollsrf of 3.3, since the patterns is too complicate and small, and also some part is hard to fold and stick, so I did not choose 3.3 as my final model pattern.

Task 02 Matrix The final decision of grid Manipulation for my 3D print model is 1.4, and others are test for my model. For the platonic octahedron distribution, I perfer the regualr geometry distirtudion so I finally choose 2.4. I also choose 3.4 as my final modle, because the size of every octahedron varies from big to small on the regular basis compare with 3.1, and the distribution is very regular and concise compare with 3.2 and 3.3.
