Critical Reading: Kolerevic B. 2003. Architecture in the Digital Age
Kolerevic described three fundamental types 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)
Three fundamental types of fabrcation techniques described by Kolerevic are substructive fabrication, additive fabrication and formative fabrication. Muti-axis can be used to substruct material, which can be volume, surface and axially constrained. The complexity of the objects decide the number of the axis. Laser cutting is a good example of substractive fabrcation. Additive fabrication use the method of adding material to fabricate objects. It usually used on the multi-layer objexcts, 3D printing is a great example of using this incremental layered method. Formative fabracation is a process of creating different objects shapes or formation,and the way to do this is to employ mechanical forces, restricting forms, heat or steam. Computer Numeric Comtrolled(CNC) fabrication is a process to use the computer system to controll the movenment of machines, Which is a great way to increase the possibilities of the fabrication results. in another aspect, CNC is an eficient way which can increase the production rate and save labour cost.

SURFACE AND WAFFLE STRUCTURE Surface Creation
Using the grasshopper to create the surface, the advantage of this parametric software is able to generate various of surfaces by changing the number of slider . It is very visualized to see different resultsof changing the value of either edger sliders or point slider and it is easier to choose the surfaces just by copy and paste the scripts in grasshopper in an organized way.

S1
S2
These are the different results showed in Rhino after manipulating the line sliders and point sliders in Grasshopper. S1, S2, and S3 has some crazy shapes but difficult to make waffle structure ,the position of the lines lead to some crazy contours which is hard to be realized in the physical model. After experimenting the process of making waffle structure, i decided to choose S4 to be the surfaces of my final design. S4

SURFACE AND WAFFLE STRUCTURE Surface Creation
These two surfaces are used in my final design, which is because of the shape of these two surface is stable and developable, for example, wide open space in the middle is a good circulationspace and also the top of the surfaces create greate shading space which can be thought as the space like shelter.
5
Isometric View
Each surfaces have 3 patterns, they are sharing the same 2D patterns which has a traingular-shaped opening. To the left surface, all the patterns i used have openings and these openings was generated from small to large. To the right surface,i used 2 opening patterns and one closed pattern in order to create a greate shading area, which also leave a bit private interior space.
6
My waffle structure focus on the stabality and the number of the contours is suitable to be either supporter or functional structures(eg: sit, climb).

To prepare for the laser cutting, i have to separate the cutting layer and etch layer.The difficulty i met in this part is the distance of the tab, at the begining my tab distance was 1 mm which is too thin to be fold, so i have to change it to 3mm and

When i was trialing with different literation, i want to explore the possibilities of the combination of patterns and surfaces. Therefore i changed various element, for example, the shape of surfaces,

distance of offset grid, types of attractors(point attractor, curve attractor), domain grid number and different patterns. The concept of my final design is to create a panel can give people greate light/shadow experience and also can be multi-functional by puting it into different position.

2D pattern with one opening,
Solid pattern with no opening, triangular shape create big shading If people stand on this area, they cant tell these patterns have openings

SURFACE AND WAFFLE STRUCTURE Photography of Model
The transition of panel shapes generally transfer from 2d to 3D with dynamic effect from flat to 3-dimensional. When i was taking photos of my models , i find different potential of this model if i just put it into different position. The photo on the left create a wide middle space which can be considered as place for people to walk through. The photo on the right showing the contour seperate the inner space into two parts, one can be shelter and another can be functional space。

Visual Scripting of Parametric Model
In creating iteration of my design, i mainly focus on trying various of boolean geomatrics. I find it is interesting to use two boolean geometrics, the intersection part become great inner space.
11
SOLID AND VOID Surface Creation
The first boolean i made in TaskB, just use general 50*50*50 cube to boolean, and this one need lots of supporters while doing the 3D printing.
I tried a larger volume and put it half-inside the 150*150*150 cube. The result of it is to create a solid volume with lots of semi-open spaces and overhanging. These two features inspired me to create a functional pavilion which can let people climb up and get into comparatively private place to have a rest.(eg:sleeping, chatting)
12
To the third model, i used cylinder to boolean intersection. The intersection between cylinder and icosahedron create many slop surfaces which is difficult for people to walk or sit, but these slop can be lean on if the angle is suitable.
The final model, i still choose to use cuboid to boolean section, because i like the vertical cut made by cube which give people a clear boundary between inner space and exterior space.

Both of the third and forth model used 2 different lunch box component. Third model combine the cube and icosahedran, while the final model used the cube and octahedron. The process of making these two model is similiar, both of them used cube to make inner space and use another geometry to make the entrance to the cube.
