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’s three fundamental types of fabrication as outlined in the reading are; subtractive fabrication, additive fabrication and formative fabrication. Kolerevic describes subtractive fabrication as fabrication in which a specified volume of material is removed from the source solid. This can be done by electro-, chemically- or mechanically-reductive processed. This form of fabrication however is restricted by the volume, axis on which it can be subtracted and surface. Additive fabrication on the other hand involves adding material layer by layer, using machines such as 3D printers. A benefit of additive manufacturing is that it uses only the material required thus it is more efficient and produces less waste. Finally, formative fabrication utilises other machines to reshape desired materials into desired forms. For example, steam bending timber or heating and then hot rolling steel. Computer Numeric Controlled (CNC) fabrication has a great potential with parametric modelling as data can be imputed straight from the computer program into the machines computer to produce the end product, eliminating any need for technical drawings or manufacturing drawings. It also enables a faster production and prototyping turn around as you can simply change the data input into the machine by editing the script on the parametric model.

Surface Creation

Surface Iteration 1a

Surface Iteration 1b

Surface Iteration 1c

Surface Iteration 1d

Grasshopper Script

To enable the most efficiency in prototyping and iterating my surfaces I chose to create a continuous script. From the box to the surfaces all the way through to the panels there was a continuous script which meant that if I was to change any of the initial parameters the whole script and surfaces would update. Labeling my script was very important as it ensure I knew where I was up to and it made it easy to know which part of the script related to what part of the model.

Week Four Panels & Waffle

Panel Isometric

Waffle Isometric

I chose to use both a 2D and 3D surface for my 2 different panels. Within my 2D surface I have used the lunch box tools creating 2 different panels and combining them. For the second surface I used attractor points to manipulate a 3D geometry over the surface.

The Waffle Structure for my surfaces was made complex buy the drastic curve in one of my surfaces. The Waffle Structure has a great variation in width from the base to the top with some ribs being cut short due to the variation. This all meant that labelling and correct placement of parts was important during setup, print and construction.

Week Four

Laser Cutting

Creating a Laser Cut file for my model was seemingly straight forward however on my first file I made the error of forgetting to change the lines connecting the tabs to the panels to etch layer. As a result I cut off all my tabs and had to adjust and resubmit my file.

Objects sharing same line to save on cutting time and cost

Waffle Structure cut on 1mm Mount Board

Dashed lines etched for folding

I made sure to share lines where possible and then made 2d of the whole file to ensure that there was only 1 line to cut on the overlaps. I also joined lines on the same layers and used the commands; purge and seldup to clean up the file prior to cutting. Limitations of the Laser Cutter are that it can only cut flat surfaces and its workable area is only 600x900mm.

Week Five

Grasshopper Script

Boolean Iteration 1a

Boolean Iteration 1b

Boolean Iteration 1c

Boolean Iteration 1d

Scripting my boolean form in a clear and orderly manner was very important to enable me to experiment with different attreactors and manipulation tools. I tested many tools from lunch box and paneling tools to create different geometries and change how they moved within the cube. As seen in the right hand side images, some objects did not work as well compared to others as they did not contain many geometries protruding through the cubes perimeter surfaces.

Week Five

Isometric

The isometric I have chosen to use highlights some of the intricate spaces created from the intersection of my chosen geometries. Its also provides a sense of where boundaries may lie through the use of shadow, internal spaces and indirect pathways created by the booleaned geometries. It also highlights some of the ‘light-wells’ opening into the internal mass which could be larger rooms or niches dependant on scale. Determining which iteration to develop was a combination of which shapes worked well and which attractor styles I liked the most. It was important to obtain a combination which hinted to the original from but at the same time created interesting booleans. Then selecting which section to print was difficult as some of the more intricate sections were not able to be 3D printed. This was due to the internal nature of the geometry and not being able to remove support structures. To print my chosen section I rotated it on the Makerbot software until I found a position that would limit the amount of support material needed. Some of the spatial qualities shown in my model include the triangular intersections where more than one geometry have met to form a layered boolean intersection. As a result the spaces are not clearly defined or obvious and so you are lead thought the spaces as defined by the geometries.

Boolean Isometric

Looking at porosity and permeability the model addresses these ideas through the unequal subtractions from the main cube. Light, water, air or even people can pass through the different entry points created however the amount or flow is determined by the size of the subtraction. This then also helps to define the spaces as being intimate or large and public.

Task 01 Matrix I chose to explore the differences between surfaces touching and then being pulled further apart (1.1-1.4) in the first instance. From there I after selecting the surfaces I liked best (1.4), I explored what effect moving the attractor point into the bottom corner of the surfaces verses the top (2.1 + 2.3). I also at the same time looked at pulling the point in between the two surfaces and then far away from both (2.2 + 2.4). Then moving onto the panels I explored both 2D and 3D panels using many tools and plug-ins (3.1-3.3). From there I merged some of the past iterations to form my 2 final panels (3.4).

Task 02 Matrix For the development of task 2 I started by looking at manipulating the grid using different forms of attractors (1.1-1.4). I also looked at adjusting the grid number (1.4) but decided that this would create too much subtracted space later on. From there I looked at manipulating the distribution of the object within using the same types of attractors (2.1-2.4). From this process I selected which two sets I liked the best (1.3 + 2.3) and looked at experimenting with objects. Finally I tested what type of attractor would work best to manipulate the objects ending up with my chosen boolean (3.4).
