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 type of fabrication techniques in Kolerevic’s reading are subtractive, additive and formative fabrication. Subtract fabrication is a removal of a specified volume of material from solid by using electro-, chemically and mechanically-reductive process tp attain desired form. Additive fabrication involves incremental forming by adding material layer by layer. Formative fabrication utilises external forces such as heat or steam to reshape or mould material into desired form. Computer Numeric Controlled fabrication with parametric modelling allows the fabrication of the complex designs directly from somputer software. The data can be directly impluted from the computer program into the machines computer in order to produce the end product, fabricating the digital model into physical model.

TASK 1


Week Three

Surface Creation

The process is creating a fixed 150X150mm fixed bounding box to produce two srfaces. The edges of the box from the decontruction of the BREP STEP were divided which were used as the parameter of the surface.


Week Three

Surface Creation

Four different type of surface interations were created while play around with the grasshopper to have a understanding of grasshopper and create a set of surfaces for later use.

Week Four Panels & Waffle

The paneled surfaces are both made up by 3D models. The grids were offset in different heights. Points attraction distribution was used to achieve the wave shape on one side and make all the top points of the pyramids pointing to the same direction. Some open surfaces exist on one side to simulate the windows on the building. while the other part is created by the pyramids with different orientation.

The waffle structure is created based on the shape of the surfaces selected. The upper curves of my surfaces are not the same level, therefore, the waffle structure on Z axis failed to build. It due to that the start points were not attached with the end points correctly.

Week Four

Laser Cutting

After finished the digital model in Rhino and grasshopper, unrolling the surface to laser cutting achieves the digital model into the physical model. The edges of the unrolled piece were placed in different layers. The waffle structure was cut in 1mm mountboard, while paneled surfaces were cut in 290 gsm ivory card. The waffle structure was unrolled by grasshopper, while the panelled surfaces were unrolled by Rhino.

Week Five

First,a 150 x 150 x 150 box built in the grasshopper was subdivided into 9 cubes. Point attractor and curve attractor effects were used to manipulate the grid and transform the shape to attempt different shapes and differnet sizes. Weaverbird’s mesh pyramids in grasshopper were used as the internal objects and modified by number of sides and top points. The bounding box and internal objects were baked from grasshopper into the Rhino. In Rhino, the command _booleandifference was used to cut the box.


Week Five

Isometric

My model is created by subtracting a 150x150x150mm box with weaverbird mesh 4 sides pyramid. The point attraction distribution was uilised in grasshopper for both grid manioulation and shape tranformation. My module is inspired by the stairs looking from the top view. To achieve the model looks like seeing from the top view. All the attraction points and curves were set on the ground. Similar to the stairs, the elements on each layer are same. Because of the point attraction, the space and volume will smaller in size when the layers goes down. There are plenty of empty space exist in my model, which will make the space feeling like accessible.

Task 01 Matrix The final surfaces selected is 1.2. I have created very curvy surfaces and flat surfaces and tried to find the balance between them. I uilised the point attractor distribution for both base grid and offset points. 2.1 was selected to panel. The final paneled surface is 3.3. One surface consists of open and close models which tend to simulate the windows on the building. As for the other surface, a same model with two different orientations reduce the consistency of this surface, which add the contrast between these two surfaces.

Task 02 Matrix For both grid manipulation and shape transformation, point attraction distribution was used. I tend to created a ‘top view’, therefore all the points were located at the lower part of the box. In that case, the internal object will ruduce in size, when the height reduce. Therefore the 1.1 and 2.2 are selected. To make the model have the feeling of accessibility, 4.2 which have more space is the final model selected.
