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)

Subtractive fabrication consists of the manufacturing of materials through mechanised processes, via the reduction of the material itself. Unlike 2D fabrication, subtractive fabrication utilises a third axis (z-axis), enabling the production of 3D forms. In addition, CNC Machining is the most common method and in the 1970s was experimented with for architectural models. Additive fabrication is a result of the addition of layers of material upon one another. The technique produces far less waste than subtractive fabrication since the only material required is that for the product itself (excluding potential supporting materials). 3D printing has recently become a widespread method of this technique. Formative fabrication is the process of reshaping or deforming a material. Elements of heat/steam, mechanical forces and/or restricting forms are applied to mould the material as desired. Parametric modelling enables rapid and economical mass customisation, allowing the visualisation of new forms. Controlled fabrication techniques can be far more efficient and accurate than traditional construction methods. Therefore, combining parametric modelling and controlled fabrication would reshape and broaden the horizons of architecture. New materials, production techniques and structures could arise, giving rise to an ever evolving discipline of architecture.

In order to achieve a greater surface area, at least a portion of the vertices were extended to the outmost coordiantes of the bounding box. Through parametric modelling, diverse surfaces were able to be created accurately and efficiently. After multiple prototypes, an interest of both the interior and exterior boundary was formed. In particular, the more curved surfaces appeared to present more fluid and interesting spatial qualities.

Week Four Panels & Waffle

Weaverbird anit-prisms were used to create a light-weight, permeable and geometrically intircate surface. The panels differed depending on the surface, consisting of either hexagonal anti-prisms or rectangular antiprisms. Such delicate shapes allow light to permeate through the entire structure, providing a distorted view of the structure’s surroundings from both the interior and exterior.

The waffle grid is hollow to create an interior volume and consequently enhancing the structure’s ability to incorporate light. Furthermore, the waffle grid is comprised of more struts than structurally required to give an impression of the two, lofted surfaces. The additonal struts favcilitate the arrangement of the panels, since they do not connect to themselves and are only attatched to the grid.

Week Four

Laser Cutting

Since the shapes were quite fine, the tabs for fabrication were only 1mm thick. This definitely made assembly almsot impossible. In addition, not having the taps joing together but only onto waffle grid proved challenging and tedious; with each piece having to be glued and to the grid individuallly.

Week Five

Comment on the process of scripting and designing your boolean form. Label your images here. Use white colour background in Rhino only. A collection of hexagonal di-pyramids converging to an attractor point were created using weaverbird. When applying boolean difference to the original bounding box, sections with harsh geometry resulted.

Week Five

Isometric

Similar to M1 Part 1, the structure derrives from a variation of hexagonal prism. It’s form posseses qualities of weightlesness (eg. cantiever and over-hangs) resulting in accessible interior volumes. Multiple chasms and subtracted sections provide paths of access and regions of partially enclosed, semi-private areas. In reagrds to fabrication, the structure consists of angular lines with all sections of the model having sufficient structural integrity to support themsleves.

Task 02 Matrix Both the shapes and their orientation of fig. 3.4 and 3.3 protude more the bounding box, creating sharper and more intricate geometries once booleaned. Furthermore, the later iterations are closer related to M2 Part 1 since they too derrive from a variation of a hexagonal prism.
