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)

Three fundamental types are subtractive fabrication, additive fabrication and formative fabrication. Subtractive fabrication: “involves the removal of a specified volume of material form solids”.It can be done by electro-, chemically- or mechanically-reductibe processed. The inherent limitations of three-axial milling leads to the limitation of the range of forms that can be produced by this machine. Additive fabrication: involves adding material layer by layer, it shares a same principle, that is the digital model is sliced into two dimensional layers. It is mainly used to make complex and curvilinear geometries. Formative fabrication: can reshape materials into desirable forms. The CNC fabrication is a manufacturing process in which “ pre-programmed computer software dictates the movement of factory tools and machinery”. The CNC process runs without the limitations of manual control. It enables a faster production since the and threedimensional cutting tasks can be accomplished in a single set of prompts.

Week Three

Surface Creation

The “List item� makes four points easily to manipulate. Since four points are the corner point of each surfaces, the change of the number can make them locate in seperate lines.

Week Four

Panels & Waffle

The direction of patterns is the same direction as how the waffle structure steps in, making panels and the waffle structure integral. For the left panel, the design of each unit is the combination of 2D and 3D with one eighth triangle and a pentagonal pyramid.For the right panel, the pattern has a triangle cut-out on each triangular pyramid, creating a light transmission part.

The hollow waffle structure is inspired by the Grand Canyon, the shape can widen the spcae of height and width. Compared with the rectilinear symmetric structure, the curvilinear structure makes the circulation more liquidity and variety.

Week Four

Laser Cutting

When preparing for the laser cut, I need to unroll the surfaces first. The black lines shows the cutline and the redlines are lines for folding.

Week Five

When doing the boolean differece, I found it useful and it is different from the “Trim“. It is important to get the right order of selecting two objects, which is substracted from.

Week Five

Isometric

For task2, I explored the sphere first and then tried to use more complex cubes, such as diamond-shaped one.The booleaned geometry can still tell the original form. The cutoff part has both horizontal and vertical intersection. Where the intersecting geometry interacts with the surface envelope creates open and semi-open space. This model can be treated as different elements in daily life, architectural system and ornament. It can be treated as seats, smaller space is for kids while the larger one is for adults. It can also be a climbing wall. It can be apllied to be a ceiling as well. The lights can be placed in the hollow space. The porosity and permeability of the form improve light effects.

Design Matrix 1:5

Task 01 Matrix I think of the relationship between two surfaces, including parallel and intersecting. Then I tried to find different ways to make the surfaces have the variation of the width and height. I chose the first group of surfaces to develop the waffle structure. The streamlined and curvilinear form better shows my understanding of the threshold and circulation. The waffle structure has hollow parts which make air flow and bring sunlight in. It is functioned as the connnection between the outer space and inner space, public open space and relatively private space. The patterns attached to the panels play with the light and shadow. The mix of 2D and 3D realises the variation of the dimensions. On the other side, the pattern with triangular hollows guarantees enough light from all directions.

The panel got a triangle cut-out on each triangular pyramid, creating a light transmission part.

Task 02 Matrix After exploring the curve attractor and point attractor, I prefer the curve attractor. For the transformation, I chose the linear one since the clustered one is a little bit messy and limit the use of the space. The size of cubes varies from small to large from left to right, front to back. The surfaces which are cutting through are in the shape of pentagon and diamond. When you look through it, it is intersting to find your view becomes wide or narrow.
