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, addictive and formative fabrication. Subtractive fabrication is the removal of specified volume of material from solids; addictive fabrication is an incremental forming by adding material layer by layer; Formative fabrication is a process involving mechanical forces, restricting forms, application of heat and steam to form the material into a specified shape. Byusing CNC fabrication and parametric modelling, more complex forms can be designed and printed in mass production, which then allows more combination of complex geometries and forms appearing in architecture widely.
I used a 150mm x 150mm x 150mm box to be the dimensions of the surface generator, surfaces will be generated by connecting points which are created on the edges of the box or lines form within the box. This method sets up constrains to the surface generating, however it can effectively control the complexity of the surfaces and ensure the possibility of developingthe surfaces into waffle.
Week Four Panels & Waffle
The left panel has rotating squares which allows a variation in casting shoadows.
I rotated the waffle structure which makes the hollow accessible and the top diagonal structure creates another side of the waffle as well.
The right panel consists of voronoi panel which has a gradation of openings from corners to centre.
Throughout the process, I did not encounter problems until I have to realize the diagonal form on top of my waffle structure. Since they are really complex that many of them intersects with each other and there seemd no way for me to just unroll it and laser cut it, I reorganized them in layers, bottom to top and connect the ribs into long strapes seperately. This helps to unroll the form into a more developable shape and I managed to build it one by one later. Another difficulty was the notches on the diagonal structure and the planes in the bottom. I got the intersections and it is easy to make notches on the planes. However, the diagonal structure has many turnin gpoints and I did not manage to use grasshopper to solve it, so I have done the notches on the diagonal structure manaually.
I took inspiration from the veins inside human body and try to use the skeletal solid to boolean difference the cube. Hpwever, the intersecting volume is not much therefore when I cut the booleaned cube, I can barely notice the skeletal form. So, I took a step backward to what I use to generate the skeletal - voronoi 3D solid. Here, I could make variation by point attractors and make a more interesting booleaned cube.
Since I made a gradation of size in my voronoi solid, I prefer to choose the section which consists as many intersections as possible. Therefore, I chose the corner which has the largest voronoi solid fragments. This section consists of 7 suggested spaces, articulating by the porosity which potentially could be walls. The solid does suggest a three-dimentional spatial concept, for example circulation in the air or second storey. If you rotate the solid threedimentionally, different spaces would then serve in different way and suggest another kind of circulation within spaces.

For the Lofts, I chose the third one. That lofts provide me a tunnel-like space to work with while a it give a flat bottom for me to create a change in landform in order to emphasize the focal point of the waffle interior. For hollow variation, I decided to use the second one which creates a gradation of open to close space which could articulate the focal point as well. For the panelling, I chose the first and the fourth ones to be the two panels. Voronoi panel offers adequate light penetration with a gradation from corners to the centre, which follows the language of the focal point. The rotating panel I chose gives a good visual effect as well as it is developable since there is a limit in rotating the panels.

Task 02 Matrix For the grid manipulation, I used the first one as I want to have as many as possible fragments that can boolean the cube. For the Point Attractor Scaling, I chose the final one,because it gives a diagonal gradation in terms of size of fragments as well as the idea of diagonal open space to close space. For Scale Factor, I chose to use the fourth one because it has a good balace between sizes of fragments and the ability to show the gradation. The booleaned geometries do not intersect with
