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)

The three fundamental types of fabrication techniques as discussed in the readings by Kolerevic were, Subtractive, Additive, and formative. By removing part of the material from the solid objects, the former uses Electricity, chemicals or mechanical work to produce the desired shape and volume. Additive fabrication is also called layered manufacturing which involves incremental formation. Instead of removing part of the material, additive fabrication produce the desired shape by adding material onto the object. For instance, the 3D printer is using PVC material which can be melted in high temperature. Therefore, the printing process is completed by adding PVC onto the built structure. By removing material from the volume, the subtractive fabrication can be done. The Computer Numeric Controlled fabrication is an accurate and convenient way to produce model with high accuracy. It can be used of building modelling, structure engineering and special experiments.

SURFACE AND WAFFLE STRUCTURE Surface Creation

By redirecting the position of each point on the corner of the plane, iterations can be produced with different rotation angles. Besides, the edge of the plane is relying on the small movement of each point on the end. Therefore, moving these point away or next to the original position can generate many iterations.

Isometric View

Two panels which includes two highest point and curve attracttion. This creates more comparison with the flat plane.

Comment on the waffle structure of your model.

SURFACE AND WAFFLE STRUCTURE Laser Cutting

By unrolling the model, the model will be able to fold up with flat paper which is an easy way to put the digital model into reality.

SOLID AND VOID Surface Creation

These are different iteration of the boolean. I explored the shape with curve attractor boolean and point attractor.

SOLID AND VOID Isometric view

Insert a brief description of your isometric here. This shows the 150 x 150 x 150 volume, not the fragment. Comment on the process of choosing which iteration to develop and 3D print in parts. What are some of the spacial qualities of your model? How does it address the idea of porosity and permeability?

Photography of Model

Write a brief description of your 3D printed parts (50 x 50 x 50 mm). What is of interest for you? The geometry? The transition of shape? The shadow or other visual effects it produces? (No more than 100 words)

Appendix Process

I used laser cutting machine to help me cut the unfolded panels of the patterns and frame. The individual panels can be separated from the main panel by pushing though the cardboard. Then I fold these panels with the cut of the laser. As for the initial 3D printing of the work2. The supporting material need to be removed.

By using grasshopper I can produce script-based shapes computed in the software instead of exploring the shape by myself. Lots of iterations can be created by changing the figure for input and the relationship between different function modules. I used point attractor and curve attractor for both work 1 and 2 in grasshopper so that the height and the direction of the shape can be changed with the movement of the curve and point.
