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)

There are three main fabrication techniques; subtractive, additive and formative. Subtractive is the removal of a specific part of the material from the solid. Additive is fabricating using the material in a layer by layer manner. Formative is the application of mechanical forces, restricting, heat or steam applied to material to create desired shape. Computer Numeric Controlled fabrication with parametric modelling provides opportunities for mass customisation, new materiality and sampling. It broadens production strategies and allows more versatility and as well as greater control of variables to achieve a desired outcome.

Week Three Surface Iterations

Creating surfaces to later panellise through the surface lofts script was simple. The script allowed plenty of flexibility in the creation of the surfaces and made it simple to control and change variables and points within the 150x150x150 cube. The more difficult task was panellising the surfaces. For one surface I used to script taught to us in the workshop. For the second surface however I decided to use weaverbird to panellise it because it was a new software to me and I wanted to develop my skills and broaden my understanding of it. Surfaces 1

Surface 4 - Final

Weaverbird proved to be quite difficult to use at first but once grasped provided another source of achieving the panellised surface. It provided a lot more ease and more opportunity for control, however many of the panels I created proved to be unworkable in the long run thus I simplified it.


Week Four Panels & Waffle

After panellising the surfaces came creating the waffle. From the outset I knew I did not want a waffle structure that was plain in the sense that all the horizontals were straight. Thus I began researching how to go about the script in grasshopper to achieve different results. After plenty of time spent on research and a lot of trial and error I deduced a script that could create a curvy waffle. I also discovered how to vary the widths so that it would not read as uniform.

Weaverbird Panellisation.

I am very content with the outcome of the waffle, however the same cannot be said for the panels. Unfortunately my panels unrolled a little strangely and thus would not connect nicely together. I had to improvise and glue the panels on as best as I possibly could on to the waffle trying to ensure it was uniform. Despite my best efforts unfortunately it looks a little off.

Week Four Waffle Variation

Waffle Width Variation

This is the script I used in order to variate my waffle structure into a curvy one with varying widths. Technically it took a lot of time, trial and error and research. However, I am glad I did it because it made me really get into grasshopper and start understanding the software better. Waffle curvature


Week Five

Solid and Void Script

Creation of voids 1

Creation of voids 3

For Task 2 I had an idea for my solid to be boolean with voids that resembled crystal like elements that are diamond and pentagon shaped. To achieve this I once again used weaverbird to develop a script. I thoroughly selected which grid points would go where and then which grid points would control the output of the weaverbird extrusions through the cube and within the cube. Developing the first iteration took a while but after that it was simple copying and pasting and changing variables. Creation of voids 2


Week Five

Boolean Iterations After completing the boolean difference with the solid and voids I went on to slice the cube. The weaverbird script created many interesting spaces within the solid but I went with cut four. I ended up choosing cut four to 3D print because of the intricate chasm-like space created in the solid. All the edges show the shapes i used nicely and you can clearly see evidence of intersection between them.

Cut 4 - Final


Week Five Isometric

After considering how this cut could possibly be realised I began imagining that a potential entry point could be a pathway into the site. This pathway narrows in to then reveal the chasm interior which mimics the way in which users of such a site would come from an open space to something closed off and reserved. The faces of the model has interesting jagged openings that could be possibilities for light penetration with the biggest pentagon on top being some sort of skylight or even just an open void on the interior.


Week Six Task 01

Task 01 Matrix The first row demonstrates the various iterations of surfaces I created using the grasshopper script with the last one being the surfaces I decided to use. The last one demonstrates the grid created by the attractor points I used as well as the control points used to create the surfaces from the cube. The second row illustrates systematically my creation of the waffle. Starting from taking the contour lines from the surfaces and joining them together, to curving two sides and then offsetting them at various widths. The last row demonstrates my process panelling the surfaces and the end result.


Week Six Task 02

Task 02 Matrix The first row illustrates the creation of the grid within the cube as well as placing attractor points to shift specific grids. The second row demonstrates the process I had in choosing specific columns within the grid and then specific points for the weaverbird extrusions to begin from and extrude to so that the intersecting aspect shown in the last row could be achieved. The last row is an illustration of the three different extrusions I used to intersect within each other to then boolean difference from the cube.
