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)

In this reading, there is three fundamental type of fabrication techniques have been outlined by Kolerevic, including additive fabrication, subtractive fabrication, and formative fabrication. Firstly, additive fabrication including incremental made by adding some material in a layer by layer mode, in a procedure which is the converse of milling. Secondly, subtractive fabrication including removing a specified volume of material from solids applied electro, chemically and mechanically reductive processes. Finally, the formative fabrication involves mechanical forces, restricting forms, heat or stem are used to the material, therefore, it can be axially or surface constrained.

Week Three

Surface Creation

The process is started from a cube in grasshopper and use the edge of the cube to divide into points. Through the combination of the points, the curves are created and then two surfaces are made. Two surfaces have many different compositions, such as they can be symmetric, intersected and so on. For my iteration, I chose two for showing the intersection, they both have a small piece of one surface cross another one. The other two iterations are not intersected. One is flatter and the other one is crooked. Image(left): the surface script in grasshopper Image(right): Surface iteration 1-4

Week Four Panels & Waffle

My two surfaces are created of two 3D panels. My idea is showing two different kinds of patterns. One is almost hollow and the other one has an opening on the top, and the patterns look towards different directions. Hollow Pattern can show the light come from different directions.

The purpose of the waffle structure is for supporting the paneled surface. For my waffle structure, the shape of it is from a tripod to parallelogram. When I created the surface, I considered the shape of the waffle. The shape of change causes one surface more crooked than another

Week Four

Laser Cutting

After finishing the design of the waffle and paneled surface, they are using two different ways for laser cutting. At the start, we studied to use unrollsrf and pt_tabs commands in Rhino to get the panels and then to make the model them together. For this assignments, I learned more to get surface in grasshopper. This is easier and can save more times.

Week Five

The process is started from a bounding box and to use the attractors to create different grids. My iterations are showing the shape, octahedron and through the different radius of shape and different construct domain.

Week Five

Isometric

My model is created by subtracting the shape, platonic Octahedron from a box. For choosing this shape, I tested many different shapes such as Sphere, Platonic Dodedcaheous and so on. I think these canâ&#x20AC;&#x2122;t appeal me. The reason for my choice is when this shape is bigger than the box, it creates an opening that the shape of a diamond. Whatever the opening is big or not. the shape will still not change. It looks more clear that compare with another shape. Although the shape of the sphere can achieve this point, it creates hook face. The cut of angle has more sense of design. On the top, there are two small openings for that the light directly into the model. To observe my 3D model, the permeability is good that there are openings on the top and also have a big threshold and small threshold. The big threshold is good for circulation.

Task 01 Matrix After creating iterations of the two surfaces in Grasshopper, I choose the surface (1.1) because of it shows different types of surfaces. One is flatter and the other one was crooked. This can attract people to want to compare with the difference two surfaces, and the pattern of the surface is also different (3.4).

Task 02 Matrix The task 2 model as by using the point attractor and curve attractor to influent the grid of interior, I choose the point attractor (1.1) for my task 2 model, which the point is located on {220.5, 79, 73} and I chose the surface (3.1) that the shape is from big to small. This can give us different openings.
