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 different forms of fabrication techniques dicussed in the reading are subtractive, addictive and formative. These are all examples of 3D modelling. Formative involves shaping heat-softened materials into a mold; Additive is the building up of a shape in payers, such as 3D printings; subtractive involves removing parts of a whole through shaving down and surfaces, such as Compuuter Numeric Controlled fabrication. These technologies have the potential to create shpes that are incredibly accurate, as well as being easily modified to create many different iterations at the same price, leading to mass customisation rather than mass production.

Week Three

Surface Creation

Insert Image of your surface script

The process of scripting the surfaces is the first time I get in touch with Grasshopper. When designing my surfaces, I initially want a dramatic, twisting surfaces. Ensuring the two surfaces not intersecting is a challenge, however, I found that not all of my design can be used to contruct waffle structure. The above surfaces I finally used is curving, but they both have sides that laid on the same dimension, therefore the waffle strucutre can be later contoured. 3

Week Four Panels & Waffle

This Panel is created by four triangular prisms combined together, and further adjust by weaverbird in Grasshopper. This solid panel forms a sealed surface, which unable the light to pass through and create a sense of privacy inside the building.

This second panel is created by a combination of a trimmed triangular prism and a frustum, with holes downwards and upwards respectively. The holes upwards enable sunlight passed through and lit the interior area. The holes downwards also lit up the ground and create shadows.

Week Four

Laser Cutting

Iâ€™m familiar with the laser cutting process as I have used it last year in Foundation of Design: Representation. I found one thing most important is to make 2D to the surfaces, otherwise it might contain polysurfaces that are 3D and cannot be printed successfully. Another important thing is time arrangement. It takes time for the fablab to execute the jobs and the queue is long when hundreds of people are waiting for laser cutting their models. Luckily I submited the file before Easter so I get my print back quickly.

Week Five

Isometric

For my final 3D section, I want to use a Boolean form that has interst and variation, as well as a noticeable pattern. Therefore, I do not simply use horizontal/vertical cutting or diagonal cutting, but rather I’ve cut out most parts that is not be booleaned, and trying to make a piece ‘floating‘. I’ve adjusted the angle and cut the piece on the top right half. In order to create stability, I left a relatively larger area down the bottom, in case the floating piece will fall down. The floating piece make it harder when it comes to 3D printing, I have to laid down the model and face the floating part to the bottom to decrease the support. My selected section also has some interesting spatial qualities. There are several holes created on different faces. To the left, It is a relatively closed space that maintains a sense of privacy, while to the right there is a wider openings that you can see through the interior structure. I would say that it is a contradictory space containing completely different views looking up or down, from left to right or vice versa. The asymetry maintains some degree of balance but more likely creates disorder.

Task 01 Matrix For the surfaces, I have created several that cannot be later used in constructing the waffle structure. I found that at least two indexs should be laid on same row/ column therefore the waffle structure can be constructed. Therefore Iâ€™ve chosen the 1.3 surfaces. For the grid, I choose random attraction as I would like to create a more random and freely shape of faces. For the panels, Iâ€™ve created a solid panel that forms a sealed space, and one with holes that enable sunlight to pass through.

Task 02 Matrix In task 2, I choose random attraction for all cells construction, grid attraction, as well as shape scaling. Amongest many iterations Iâ€™ve tried, I found random attraction most interesting as it creates a sense of freedom that we cannot manipulate, therefore it becomes easier when getting the most interesting booleaned geometry.
