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)

Kolerevic describes the fabrication tecniques of addition, subtraction and moulding. The first creates forms by the deposition of material, the second through the subtraction of material and the third through the manipulation of material through the application of force (e.g. bending). The potential of Computer Numeric Controlled fabrication with parametric modelling rests in their capacity to allow multiple iterations through the control of inputs in a script. This brings an unprecedent level of practicality to itterative design as it allows easy manipulation of the design form to generate multiple possibilites that can be easily tested in terms of prototyping.

Week Three

Surface Creation

Surfaces were scripted starting with a 150 X 150 mm bouding box that was deconstructed into edges. These edges were divided into five equal sections that defined six points for each edge. A combination of these points was used to create two lines that were then used to generate ruled (developable) surfaces. In the search for a treelike form, the first iterations tried to generate two intersecting surfaces. However, they did not offer the chance to create a wide inner volume. The last iteration focused on generating surfaces that could result in a shape that established an inner volume that widened with height. From bottom to top and from right to left, this is the sequence of iterations, the top left being the chosen one.

Week Four Panels & Waffle

2D panel was created by panelling the surface using LunchBox and then scaling outputs down by using centroids as references and then rule sufacing the resulting curves. 3D panel was created on top of 2D by changing the height of centroids within a range to create pyramids.

Waffle structure was created from the chosen surfaces that were divided into 10X10 grids. These were used as the basis for the construction of a net of vertical and horizontal lines that were used to construct the columns and beams.

Week Four

Laser Cutting

The process of creating a laser cut was based on the labeling and movement of the structural parts to the XY Plan and unrolling the 2D and 3D panel structures, that were later tabbed and had any folding lines converted to dashed lines. These were then arranged in the FabLab template according to the specific materials chosen for the structure (1mm Mountboard) and the panels (260gsm Ivory Card).

Week Five

The process of design aimed at developing volumes that translated the idea of progression, while also balancing the amount of solid and void. As a result, the top left tteration was chosen as the basis for the boolean difference.

Week Five

Isometric

Choosing the iteration for the boolean difference between the spheres and the box, and subsequent 3 sets of halvings of the overall structure, sought to generate a form that highlighted different scales and varying patterns as a result of different balances between solid and void. This variety results in a model that portrays contrasting weight and lightness from sharp edges to bulky solids. In terms of voids or internal volumes, the model makes evident the varying degrees of connection between chambers (permeability) and between inner volumes and the outside (porosity).

Task 01 Matrix In the search for a tree-like form for the model, the first iterations focused on intersecting panels. However, these resulted in sharper edges and compromised the creation of inner volumes. An iteration with non-intersecting twisting panels that formed a funneling form was the preferred one. To create 3D panels, different top grid points based on height ranges were tested. The choice of paneling pattern sought to result in different levels of porosity for different panel inclinations. The choice of a mixed 2D-3D panel for the less inclinated panel aimed to address the need to filter direct light while also allowing ventilation.

Task 02 Matrix Iterations 1.1, 2.1 and 3.1 were the chosen pathway to develop the shape for 3D printing because they offered the best balance between solid and void, while also portrayed reasonable variability of scale, form, porosity and permeability.
