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 techniques that Kolerevic described are additive fabrication and subtractive fabrication and formative fabrication. Additive fabrication is the incremental forming of the object by adding materials layer by layer. Subtractive fabrication is the removal of a specified volume of material from solids. This can be done by using electro-, chemically-reductive milling process which are multi axis. Next, formative fabrication utilises mechanical forces, heat or steam to shape the material into a desired form. The potential of Computer Controlled fabrication with parametric modelling is that Computer numerical control machinery with parametric modelling allows the fabrication of complex designs directly from the computer software. This enables a new realm of possibilities in fabrication. It also allows a faster production as you can conveniently make changes by just changing the data script of the parametric model.

Image 1: Grasshopper surface script

In grasshopper, a box is created and then deconstructed to create curves. The curves are then divided into points. The list item component is manipulated to select the points in which the surface could be created from. The surfaces are iterated in such a way that it is feasible to be constructed physically, but also has an interesting notion

Week Four Panels & Waffle

The panelling from the two surfaces is generated from two types of panels, 2D panels and 3D panels. This is to create an intricate design. Both 2D panels and 3D panels are perforated to allow variations in the amount of light entering the space.

The waffle structure is created based on the form of the surface. It is to support the panelled surface. The inside space of the waffle structure is wide on one end and narrow on the other.

Week Four

Laser Cutting

During the process of creating the laser cut file for the surface panels, the panels have to be unrolled and labelled systematically. The laser cut file for the waffle structure is generated from grasshopper. Something new that i have learnt is the steps to lay out the laser cutting file using grasshopper, after the waffle structure is constructed.

Image 1: Grasshopper Boolean Script Image 4: Shape Transformation 3, Random Scaling

Image 5: Shape Transformation 4, Reverse Point Attractor

Firstly, a box is created. Then, grids are generated from there. The grids are able to be manipulated using various types of attractors to created variation. Next, the distribution of the shape and the sizes of the shape are manipulated to create diifferent iterations.

Week Five

Isometric

The model is created by subtracting the shape Platonic Octahedron from a box. The porousity and permeability of the model is created by the interecting shapes that are subtracted from the box. Observing from the section cut of the model, the shape that is subtracted created square openings of different sizes to allow light to penetrate into the structure, illuminating the inside space. Moreover, the form of the model concaves at the parts which are subtracted out by the shapes and terminates at the openings. Lastly, the voids created have an interesting geometrical shape and sharp edges, resulting in different intensity of light on each interior face.

Task 01 Physical Model Task 01 Matrix After making iterations of four different surfaces, the fourth one is chosen because it is simple and seems more stable in form, but is also interesting as the inside space of the structure widens at one end, but narrows at the other end. Then, the regular panelling grid is chosen so that the panels could be almost uniform in size. Lastly, the 2D panels and 3D panels are mixed together to create interesting variation in terms of light entering the structure.

Task 02 Physical Model Task 02 Matrix The grid that is manipulated using 3 attractor points is used as it creates a zig-zag pattern inside the grid. Then, the regular distribution of the shapes is chosen to maintain the simplicity. Lastly, the shape transformation using the reverse attractor point is used so that the size of the shapes vary from small to large throughout the grids.

Task 1

Two surfaces are created using Grasshopper. Different iterations are made.

The two surfaces are baked from Grasshopper to Rhino.

Panels are created on the surfaces. The panelling grids, the shape of the panels are manipulated to created interesting forms.

The panels are baked from Grasshopper to Rhino.

11


Appendix Process

Two types of panels are created, which are 2D panels and 3D panels. Both are baked from Grasshopper into Rhino.

The two types of panels are combined together to form an interesting panelling surface.

The waffle structure is constructed using Grasshopper, based on the surfaces created. 12

The waffle structure is laid out for the purpose of laser cutting, using Grasshopper.


Appendix

Process

The panels are unrolled. Then, both the unrolled panels and the waffle structure are laid out and sent to Fablab.

Once the laser cutting job is received, the waffle structure is the first to be assembled.

Then, the panels are folded and glued together using PVA glue and bull-nose clips.

All the panels are glued together row-by-row to create the panelled surface. 13


Appendix Process

The first surface is glued onto the waffle structure.

Lastly, the second surface is glued on, completing the structure.

Task2

First, a 150 x 150 x 150 mm box is created in Grasshopper.

Grids are created within the box. The grids are manipulated using various attractors to create variation. 14


Appendix

Process

The shape, Platonic Octahedron is used to create the solids in each grid. Different variations are made using various attractors.

The box and the solid shapes are baked from Grasshopper into Rhino.

The solid shapes are subtracted from the box using the Boolean Difference command.

The solid is then cut using Boolean Difference function to create the final product. The solid is sent for 3D printing. 15
