Surface Creation

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 type pf fabrication techniques are addictive fabrication, subtractive fabrication and two dimensional fabrication. Two dimensional fabrication are fabricating in x and y axis in a plan. This could be the laser cut whic cut the surface in two dimension. Addictive fabrication are fabracating using additive units to form a complex. The example of additive fabrication could be 3D Printing. Subtractive fabrication is the removal of specific volumn of materials through chemical, electrical or mechanical methods. It is an extension of 2D fabrication but increasing the Z axis. With Computer Numeric Controlled fabricaiton more design possiblities could be brought about in terms of form and speed. Design iteration has been made easier therefore more ideas could be tested out in a shorter time.

Several trials have been give so that the two curve would create an interesting relationship with each other. The bottom right set of surfaces were chosen as it is clear and feasible in constructing the waffle structure.

Panels & Waffle

Laser Cutting

The main hightlight here is that I have learnt how to use grasshopper to unroll surface and making respective tags. Though the process is hard, it is useful in future when we handling with more complex project. The process of unrolling 3D panelling surface has been extremly hard this time due to the complex shape of the basic form. Some are unable to be unrolled using â&#x20AC;&#x153;Surface Unrollâ&#x20AC;&#x153; command therefore I have to unroll them manually, which is exceptionally time-consuming.

I have chosen four basic shapes in the 2D panelling surface design. There is a transition from straight line shapes to curves gradually. The overall diagonally symmetric shape is also enhanced by each individual cells, and the who flow corresponds to the curvature of the surface.

The waffle structure is relatively basic and stable. The two surfaces are designed to be seemingly symmetric so that it looks more stable and visually appealing. The reason I have chosen this set of surfaces is because it looks like an open book!

Isometric

What are some of the spacial qualities of your model? How does it address porosity and permeability? This isometric resembles the crystals found in nature. By taking the star pyramid as the basic cutting shape, its variation in direction and size and its interference with the box together create interesting forms. This is inspired from the previous trial of pyramids. Star pyramid, in comparison with tetrahetral pyramid, has more sharp edges. Therefore the form would appear to be more flexible and dynamic.

Ttrials are given by first baking out the customised shape( as in dicated in buns, diamonds, donuts and star pyramid) and then boolean them out from the baked box. Grids are adjusted accordingly to alter the form and create more variation.

My finalised developed surface is the second set of surfaces because they do not intersect with each other and thereofore easy to build my waffle structure

In the end I chose to develop the last option (hexagon star pyramid) so that there would be a crystal-like rock structure. This was what came to my mind after I have try several shapes (both curvy and sharp) and realised the edges of pyramid along with the variation in size could cut out the crystal.
