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)

The three fundamental type of fabrication techniques are subtractive fabrication, additive fabrication, and formative fabrication. As the name says, subtractive fabrication removes parts of materials from solids by using electric, chemically or mechanically-redictive processes, whereas additive fabrication is adding materials layer by layer. formative fabrication creates the shape of a maeterial involving mechanical forces, retricting forms, heat or steam.It may involve both addictive and subtractive fabrication in the processes. CNC fabrication has a great potential with parametric modelling as data can be imputed straight from the computer program into the machines computer to produce the final product, It also enables a faster production and prototyping turn around as you can simply change the data input into the machine by editing the sript on the parametric model.

Week Three

Surface Creation

I tested various points of the surfaces by changing the curves that points were sat on, as well as the point locations on each curve.

3

Week Four Panels & Waffle

I used simple triangular form for both of the two panellings. One of the panlling was controled by two cross-shapped curves that intersact at the center of the surface. The other panelling was formed by triangular form with hollowed small triangules, which give the sense of opening.

I deleted the bottom level of the horizontal structure in the middle, because that will not be fixed for the pysical model. For the shape of this structure, it looks like a shirt collar form the front.

Week Four

Laser Cutting

After importing the Rhino file of waffle structure and 2D panellings into the Laser Cutting File, I arranged those curves into specific box. In order to save money, I overlapped some of those curves, and used Make 2D command for deleting overlapping curves. Additionally, I explode the texts into curves. Then I put curves that needed to be fully cut into Cut layer, and put curves that needed to be half-cut into Etch layer. In addition to this, I put some of exterior linework into etch layer in order to aviod those pieces to drop down. I found make 2D command is quite useful for avoiding overlapped curves. Moreover, it is a good practice to change exterior linework to etch lines, because when I got my laser cutting stuffs, I can see what would work, and what would not work. Importantly, I have learned how to save mony for laser cutting.

Week Five

In order to get the final choice of the boolean form, I kept changing the random/curve/point attractor of the grid and the sphere distribution, testing the factor of the scale of the spheres.

Week Five

Isometric

The first iteration is quite consistant and does not contain enough variation between interior spaces. The second and the third variation do not contain enough intersection between spheres. The reason why I chose the final boloean iteration is that it contains various size of the interior spaces, enough interaction between spheres and the bounding box, as well as sufficient intersection between spheres. For this sectioned boolean model, it can be considered as a pavilion. Firstly, the intersection between speres create circulation between spaces. Secondly the intersections between sphere and the surface envelope create open spaces so that light can enter into. Thirdly the solid part create threshold between levels, spaces, andisolate the interior from the exterior.

Task 01 Matrix My first two choices were quite simple and optional, so I tried to twist one of the surfaces at the third time, but looks weired. I decided to use the final iteration because the variation of the distance between the two surfaces would make my model look like a shirt collar.
