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 types of fabrication techniques are: 1. two dimensional fabrication 2. subtractive fabrication 3. additive fabrication The potential of Computer Numeric Controlled fabrication with parametric modelling makes it a lot easier to move from digital design to fabrication. It is controlled by computer system that uses coding. It is already been used in the design industry and it helps the production of complex structures such as curved structures.

Surface Creation

When iterating my surfaces, I tried to twist my surfaces at the very beginning. But then I realised that twisted furfaces (image 1) are not easy to build waffle structure with in Grasshopper. So I moved on to cahnge it into very simple surfaces, which I found a bit boring. So I started to explore intersecting surfaces (image 2 & 3) and tried to build waffle structure for the surfaces. However, it was not easy to do that in Grasshopper, and it would be hard to do the panelling for intersecting surfaces as well. So I went back to the first stage and kept on challenging the twisted surfaces. I made one surface twisted and keep the other one simple because I wanted to see the difference between the two.

Week Four Panels & Waffle

I created 2D & 3D Panels for my two surfaces. I was trying to create a variation of heights, which I thought would be quite dramatic and powerful. And I also tried to make the directions of the small pyramids more varied by using Point Attraction and Point Slope Attractions. In addition, I moved both sides of the offset grids upwards in grasshopper to make the shape of the panelling even more dramatic.

As one of my surface is twisted, the lofts would be self intersecting and would not work if I simply follow the steps shown in the workshop session. So to solve the problem, I changed the X & Y unit vector into vector two pt and define my own vector by plotting two points in Rhino. Then I need to use my defined vector to change my contours and extrude the notches/triangles.

In terms of lights and shadows, I cut some triangular holes on 2D panel to allow lights in. Also, the dramatic shapes of the pyramids cast very interesting shadows on the panel itself and the ground.

During the process of creating a laser cut file for the waffle structure, I actually had quite a lot of problems. Grasshopper was a complete new thing for me, and starting to do the scripts was quite confusing. It was hard for me to pick up my own mistakes in Grasshopper because I could not understand the scripts. When creating the waffle frames for my twisted surface, I could not make the directions of the extrutions of the notches correct, and it turned out that I needed to change the unit vector of the extrudtions as well.Once I started to

Isometric

Insert a brief description of your isometric here. Comment on the process of choosing which iteration to develop and 3D Print. What are some of the spacial qualities of your model? How does it address porosity and permeability? I tried out all the shapes in lunchbox and decided to use the platonic shape because I like how it creates both regular and irregular shapes at the same time. Some squares are cut out at the top of this model, which are varied in sizes from left to right. The irregular shapes at the front gradually change from left to right, and from top to bottom. I thought this gradual change in this model is very interesting, so I decided to keep this quality in my 3D print. In contrast, the shapes inside are more regular. This contrasting between regularity and irregularity is quite interesting as well. In terms of porosity, lots of small holes were created in my model because I designed the shapes to be smaller and more dense. So these cut outs would allow small lights coming through. And this would be good for the lighting in the pavilion as well as creating semi-open spaces.

Task 01 Matrix When making iterations of the surfaces, I tried on twisted surfaces and intersecting surfaces and attempted to build waffle structure for those surfaces. At the very beginning, I could not fix the waffle structure for the twisted furface (refer to 1.1) because the frames would bend and go through the surface, and I did not know how to fix that in grasshopper. So i moved on and explore other surfaces and started to try intesecting surfaces (refer to 1.2 & 1.3). I attempted to split the surfaces and build the waffle structure, and it did not work. So I actually went back to my twisted surfaces design and redesigned one twisted surface (refer to 1.4), with two edges of the surfaces parallel to each other. This created a narrow entrance, and I decided to created a wider entrance on the opposite side to make the model go from narrow to broad. And when I design the panellings, I tested on different 2D & 3D panels, and decided to create different heights of pyramids and 2D triangular panels for each unit. This gives a variation of heights, which creates interesting shadows. And this complex actually increased the density of the model. In addition, I decided to cut out triangular holes in the 2D triangular panels to allow lights go through. Furthermore, I moved the offset grids upwards to give it a more dramatic effect. And I also used different Attraction methods on the surfaces.

Task 02 Matrix Comment on the choices you have made while iterating on task 2. Which versions your chose to develop and why? While iterating on task 2, I was really trying to achieve irregular and regular shapes as well as a gradual effect in my model. So by iterating the grids in grasshopper, I achieved an irregular distribution of gemotries. Then I tried on the geometries in the lunchbox and decided to go with the platonic transforamtion because it creates square shapes and other irregular shapes, which are contrasting and interesting. I also tried on different attraction methods and decided to go with point attractor because it was more dramatic, and by using two attractor points, I achieved both irregular and regular shapes in the model.

Fabrication of the waffle structure and panels

Testing on the 3D panels before laser cut - also fixing the tabs in Rhino - it was actually quite hard to make this 3D panel because itâ&#x20AC;&#x2122;s quite small, and it was also hard to make the connection neat

Building the waffle structure - it was actually quite easy to fall off, so I had to use some glue
