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 are Subtractive Fabrication, Additive Fabrication, and Formative Fabrication. (1) Subtractive Fabrication: A Technique where the removal of a specific column or material is done from a solid, using electron, chemical or mechanically reductive process. e.g. Laser Cutting. (2) Additive Fabrication: A process which depositing materials are added in layers, the process is done by creating a digital solid model, then slicing it in 2-dimensional layers. The information is used by the manufacturing machine to recreate the physical product by layers. e.g. 3D Printing. (3) Formative Fabrication: the reshaping or deforming of a material by using technical forces, restricting forms, heat or steam. e.g. CNC Bending / Folding.

Computer Numerical Control (CNC) Machining is the a fabrication process which controled by computer systems. This is a machinebased processes in manufacturing.

Isometric View

The left surfaceâ&#x20AC;&#x2122;s panels has more perforations with sizes being the smallest at the highest and lowest corner and largest in the middle. The intial design idea is to creat a waterfall feelings so I deisgn the highest surface on the top with highest pyramid and on the lowest part the surface becomes flat as a 2D panel.

The bottom face of the waffle structure needs to have sufficient larger area than the top face to support the overall waffle structure. this creates equal distribution of weight across the whole structure. The waffle is divided according to the distribution of the panel so that the structure will be hided when viewing the panels and also easier to glue the panels to the waffle.

SURFACE AND WAFFLE STRUCTURE Laser Cutting

The Laser Cutting Panels were created by using the unroll commond in Rhino. In unroll surfaces were very dispersed, so I were trying to link the maxmum surfaces together to generate minimum tabs to reduce the work time after printting them out by comparing the marks in Rhino models. The waffle Laser cut panels were created by Grasshopper. the panels are oriented to the Y plane and i hide the text tags in the Laser Cut file in order to have a clean Laser cut result.

Photography of Model Details

For the Laser Cutting Panles, firstly, I used Etch for the folding lines. According to the the laser cut, the machine can only cut one side, so I spend some time to work out which line is fold forword and which backwork. After that, I used cut knife to fix the lines for better folding result. On the right side panels, some parts becomes very small, that cost me so much times to put them together and fix the holes in between.

TASK B SOLID AND VOID

The reason I choose this result is because this module has very interesting space for using. This module can be considered as a building and also a sculpture. It has walls, thresholds, boundary and also sitting space. People will enjoy the space in this module.

While rialling with different iterations, I intended to create a form that has many dimensions to it when viewed at different angles and also with variation in the trimmed surfaces. Therefore using point attractor I needed to arrange the distribution of shapes with some receding backwards and some coming forward.

Test Models

Final Present Model

Testing models were generate for testing better 3 D Printing results. Because we are doing 3 D Printing in teh real life, some parts of model will have supports and some of them are hard to take off. According to this test, I develop the final module.

In order to have clean model and less support I devide the model in 2 - 3 parts then use Supper Glue to put them together. (There are two models in the final print out model)
