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 fabrication techniques that have been described by Kolerevic were subtractive, additive and formative. Subtractive fabricaton produces products through removing a specified volume from a large material using chemically, electronically, or mechanically-reductive procedure by 2D or 3d milling machine. Additive fabrication is also known as layered manufacturing, that involves incremental formation by adding material layer by layer using machines such as 3D printers, which is less wastful in terms of the amount of material used.Lastly, formative fabrication such as creating steam-bending timber, produces the desired shape through reshaping the preferred material. CNC fabrication has the potential to enable faster and more creative parametric modelling, as the data can be imputed straight to the computer and the need of technical drawing can be eliminated, which makes it more efficient to improve and explore the design by simply manipulating the data script.

Week Three

Surface Creation

While scripting the surfaces, I made sure that the screen was tidy and the data was properly grouped and continuous so that if I were to alter or improve my script and design, I could easily track down the part that needs editing and the changes would be updated as the script was continuous. It is also important to understand the logic behind the script, which is helpful for trouble shooting as well.

While selecting the desired surface iteration, a few aspects were focused on. It was important to develop onto an iteraton in which the surfaces did not overlap or had contact with each other so that the final two panels would be nicely separated. Additionally, overly complicated iterations were also avoid because it would not be advantageous when it comes to fabrication. Therefore, the selected iteration contains two intereating yet not overly complex surfaces that did not overlap on top of each other.

Week Four Panels & Waffle

The panelling of the two surfaces included many varations of shapes, perforations and heights to compliiment the shapes and flows of the surfaces in great detail. I manually created 2 types of 3D patterns and 4 types of 2D patterns, and then I set them in grasshopper to bake them out in Rhino.

The wafflie structure gained complexity from one dramatic curve of one of the surfaces. The structure has three substantial-sized surfaces, which enabled the structure to have multiple architectural potentials by utilising different surfaces as the base.

Week Four

Laser Cutting

For the creation of the waffle structure part of laser cut file. It was cructial to label the individual objects as their differences were minor. Another point worth noticing was that I double checked that my cut lines and tabs were on separate layers.I placed the objects in a way that some of them shared the same edges and exoploded and joined them back together. I then cleaned up the edges and curves that were not needed so it took less time to print.

6


For the creation of the panel part of laser cut file. It was essential to correctly unroll the 3D patterns and make sure there was no overlapping of the unrolled patterms. Then, the tabs were adjusted because very rarely the tabs were all added correctly by Rhino. The individual objects were also labelled so it would be much more convinient while constructing the panels.

Week Five

While scripting and designing my boolean form, I made a continuous script in order to create and edit my boolean form more efficiently, because if I was trying to change any step within the script, it would be updated throughout the whole script quickly. I also grouped and labelled the groups so it would be easier for me to find the part that I wanted to edit and troubleshoot if any error appeared.

Boolean form A

Boolean form B

Boolean form C

Boolean form D

While I was creating and selecting the boolean form, I focused on generating spaces that had different qualities (public, private, open or enclosed) and thresholds that defined the spaces. Therefore, I created boolean iterations through at least 2 shapes to explore more viaration of space. However, while sectioning the boolean form, I made sure that the created section has logical space.

10


Week Five

Isometric

This iteration was chosen because the spaces have multiple qualities could. There are extremly open and public area as well as semi-private and enclosed spaces. Therefore, it has a potential to function as many architectural elements on different scales. The space in my model has qualities of both openess and privacy, as the booleaned geometry has features from both Platonic Octahedron and Platonic Icosahedron (multiple-edged shapes), which makes the space that they create appear to be sectioned without having physical barriers. Therefore, the space can potentically create slightly private moments due to the ‘invisible barrier’ even the space itself feels open. permeability and porosity were explored through creating multiple space that penetrates the whole structure.

Task 01 Matrix I explored different surface iterations and decided to develop the first loft set on the top-left corner (reasons mentioned in previous sections). I documented the varation of my offset grid as it was crucial for me to generate different heights of the 3D patterns.Then I demonstrated different patterns that I used to create my panels.

Task 02 Matrix While iterating task 2, I experienced manipulating the space through moving the attractor point around. Then, after made a few unsuccessful boolean forms, I payed more attention to the distribution of the shapes that I was using. Finally, I explored the tranformation of the boolean forms according to the attractor point. Afterwards, while creating my sectioned boolean form I repeated the process again with a different shape so I had two sets of shapes. I combined them together to create my desired boolean form.
