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 types of digital fabrication outlines by Kolerevic are 2-dimensional fabrication, additive fabrication, and substractive fabrication. With the aid of CNC fabrication, products can be made directly from a digital input at high precision. Fabrication methods such as 3D printing, laser cutting and CNC milling enable products to be made with great speed and precision. Additionally, parametric modelling provides avenue for designers to use iterative methods to generate design, and achieve the best possible outcome. Moreover, customised products can be created at no additional cost compared to mass-produced.

Surface iteration matrix

In generating surfaces for the structure, I strived for extremely warped surfaces while not compromising the structural integrity of the structure. The 2 surfaces twist and pull away from each other to dramatic effect while a reasonable amount of the bottom of each surface touches the ground. Since the top edge of the surfaces did not have these limitations I went to extremes to create an interesting and almost reciprocal relationship between the 2 surfaces where opposite vertices pull away from each other.

Week Four Panels & Waffle

I explored a number of different panels based on a number of variables I set. The panel I ended up using was the undulating panel and one that was half 2D with apertures.

The distorted surfaces helped create an interesting twisting form in my waffle, however the choice to use a paneled surface as the brep to create my waffle was key. The aggressive angular waffle combines with the panels surface to unite the structure and skin.

The undulating panel was chosen due to how it blurred the gridlines to create interesting tessalations.

The seamless transition between the structure and skin forms a building envelope that functions as one cohesive unit.

The perforated panel displays a duality between private and public depending on the viewers angle.

Using a basic pyramid as my starting base, I played with the rotation and height of the secong smaller square. Using 1 rotation, 3 different levels of height, and 3 different sizes, I iteratied 18 different panel varieties. 1.0.1.2.0

1.0.2.2.0

I chose 1.1.3.3.0.

1.0.3.2.0

The smallest size I worked towards was teh most successful and the undulation of the 45 degree square rotated above and below the base created seamless transition between panels.

Week Four Laser Cutting

For the laser cut for my panels, I used a dotted cut line for my folds. The dotted line was made using rhino dash command. Afterwards I adjusted some of the dotted cuts manually to mach sure no edges would be compromised by to many dotted cuts on the edge, I also left some cut lines etched so the panels would not have to be taped (but Fablab still taped it). For the waffle I made sure to share as many straight edges as posibble to save time and money.

Week Five

After encountering the Weaverbird Dipyramid I attempted to construct the geometry myself in Grasshopper. The geometry was made by extruding a polygon to 2 points. By using an attractor point I was able to cause the shards to radiate from a point. Similarly to WBâ&#x20AC;&#x2122;s dipyramid, I can control the number of sides on the polygon and the width but my own script offs more control as I can control the magnitude of teh vector with moves a point to lengthen the shard.

Week Five Isometric

The boolean model has potential to become a multitude of different things. It could be a crystal structure of the remnants or a meteorite strike. However I was fascinated with the space making capabilities and how the overlapping geometries create this jagged, radiating space. To create more overlap in the geometries I used a highly warps mesh cub and adjusted the width and length of the shards accordingly. Using the attractor point to cause the shards to burst out of the cube gave opportunity for a pavillion like form to emerge. I further explored this notion by cutting the cube into further sections to reveal interesting appertures which would influence circulation around teh structure and provide interesting changes in threshold from the outside to the interior.

Waffle

Task 01 Matrix When selecting a panel to panel my surface, the panel which subtracted as well as extruded interested me. To attach it to the waffle I would require a different method and decided to use the panelld surface as the brep for the waffle script. This was not without limitations. Panels to warped would cause errors with the offset for the waffle, so severe grid manipulation was difficult to resolve. However by using parametric design though Grasshopper I was able to find a line between rebuilding offset curves and changing offset distances which fixed the script.

Task 02 Matrix While selecting a geometry, I liked the idea of a sea urchin geometry. The shard allowed me to create a large version of one within the cube, actually made of 27 geometries. After playing aroung with the attractor point and different variables, I desided to approach the booleaned geometry as a structure and saw the apertures and different types of entries into the structure.

When testing the panel I realised that ivory card it really thick and hard to fold. The tabs I made didnâ&#x20AC;&#x2122;t stick well and loocked messy. I discovered that PVA glue was strong enough to hold 2 edges and produced a clean finish. I proceeded with this method for the actual panel.
