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)

There are three types of digital fabrication techniques, that are mentioned by Kolerevic. They are subtractive method, additive method and transformative method. 1. Subtractive technique, such as lazer cut and CNC milling, means that the machine will use axes as cutting tools to burn or cut specific part from the material. 2. Additive technique, such as 3D printing, means that the machine can lay up a specific material on a specific area to build up a structure. 3. Transformative technique can reshape the material to the needed shape. Computer Numeric Controlled fabrication is very suitable for parametric modeling. Designer can use it to design many iterations to find which one is better and with lower cost. In addtion, it is very accurate and labor-saving so that designer can use it to create very complex structure.

Week Three

Surface Creation

Contain two addtional curves inside the cube

I tried using the way to choose points on the edges of the cube, which was taught in workshop, but this way is not so flexible. So I added two more addtional curves inside the cube and chose the points on them, which can create a variation in term of height (top-right isometric view). In top view (top left image), these two surfaces show a close relationship with each other. Also these two surface determine how the waffle looks like. The waffle show a especially good sense of rotation ( as is shown in next page and appendix).

Week Four Panels & Waffle

Two surfaces’ panels create a sense of contrast. The left one is plane and penetrative; and the other one is solid and sharp. In addition, there is a gap in each panel on the left surface, which will be shown in appendix. There is a effect of dissolution on the left surface.

The reason why I chose this waffle is that each piece of the waffle is rotating if you see it in top or bottom view. In my opinion, the waffle structure could be a staircase or a roof.

Week Four

Laser Cutting

One lesson I learned in lazer cutting progress is I should change one to two edges of each cutting unit from CUT layer to ETCH layer, which is mentioned in LMS. I realize that tip after I submitted the job so all the cutting unit need to be taped. When I tried to separate the units from tapes, some units were damaged.

Another tried model

Image 1: when I was doing curve attraction by using grasshopper, I suddenly found grasshopper was very convenient. I contained all the required elements, such as the start and end points of the attractive curve, the attractive curve, the grid line of the cube and the coordinators in grasshopper so every time I changed the points on the attractive curve, I could get all the required elements just by baking them in grasshopper. image 2: After I input the geometry in the grid, I thought the variation of the geometries was not so obvious. So I added an attractive point and used a ‘distance’ container to get the distances between the grids’ points and the attractive point so each distance is unique. Then I used these amount of distances to control the scale of the geometries but the variation is not so obvious because the amounts of all the distances are not large enough. So I used a series of mathematics to enlarge the scale’s domain to make the variation more obvious.

Week Five

Isometric

These two photos is two views of my task 2 3D model. It was create by BooleanDifference. In my opinion, this model could be seen as a open space. In the top photo, the arrow indicates the entrance to a passage. The passage is becoming more narrow, leading people to explore inside. There are three open frames at the left side. People can sit and cat with each other at the platforms at the left side. At the right side, it is totally open to sky. It could be a space for gallery or eating space. In terms of geometry, because I used mathematics to control the scale of all the geometries, so the space and hollow section have a flow from bigger to smaller. And it is interested to find out that the hollow spaces in different surfaces are various.

Task 01 Matrix 1.1 I tried this one but I thought it was too symmetrical even though it looked cool. 1.2 I manipulated the four points of the surface to get this iteration. Even though it cannot build a successful waffle but I found it flexible and various to adjust the solidpoints slightly. 1.3 In these surface, I wanted to create a sense of twisting and I started to use two attractive points to control the panels. 1.4 This is my final choice for task1 model. I adjusted the surfaces’ point to create a sloping top and create a strong sense of twisting.

Appendix

Process

Through this type of task, I understand much more about Digital Design and had a good experience of making model from digital to physical. I think I have a extra experience than others when I used the machine called Card Cuuter in Fablab, which is shown in the middle photo above. It shows that the machine is holding a pen ( normally it will be a knife) to draw the line in Rhino template into a ivory card. Then I can cut the card following the line it drawn. Not many people uses it and it is totally free but I have to cut many line because the knife is not sharp enough to cut the panel off the ivory card. Also the panels cut by lazer cutter is neater than the ones cut by card cuuter.

Appendix Process

In top view, as is shown in the photo above, it is obvious to see that each piece of the waffle is rotating. At the same time, with the height increases, the size of the pieces are smaller and smaller. That’s why I want to use this waffle even though I know it may be hard for panel’s fabrication.

Process These two model photographs show the waffle’s structure clearly. Under the effect of light, the sense of twisting and rotating becomes stronger.

Appendix

Process

In this surface, I used two very plane panels with a narrow gap. What I tried to create is a sense of penetration. If you see this surface, you may think it as a enclosed surface but when there is a light source inside, you can see the light come out but not directly. It seems that the light is flowing out slowly and blurring. The lit-up part of the panel can show its texture clearly.
