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)

There are three types of fabrication techniques: additive, subtractive and formative. Additive fabrication forms the desired form by adding material layer by layer, e.g. 3D printing. Subtractive fabrication involves the removal of a specified volume of material from the solids through electrical, chemical or mechanical methods, e.g. laser cutting. Formative fabrication uses mechanical force to restrict forms, where heat or steam are applied to a material so as to form it into the desired shape through reshaping or deformation, which can be axially or surface constrained, e.g. CNC printing. Computer Numeric controlled fabrication will be beneficial in dealing with large and complex information to visualize and clarify the modeling and hence reduce time and cost for modern practices. This technology can also help with mass customization by allowing ease in variation at a economic price.

Generation of surface; Index selelction has been applied to all 8 end points.

Paneling of surface A.

Week Three Surface Creation

2D Hollowed triangles.

3D pyramids.

3D hollowed pyramids.

Combination of the three.

Paneling of surface B.

Adding on the script given in the workshop, I used a 3D morph with a picture frame to generate the 3d hollowed pyramids in the diagram, adding on point attractors to manipulate the offset panel and allows the pyramids to be towards the form of the surface. I also used a random split list to create the second panel as a combination of two prototypes to give off a variation of lighting condition within the pavilion. I also changed the structure of the points through partition list to allow a area variation of the hollows on the structure in a directional manner.

Week Four Panels & Waffle

A hollow waffle structure allows for the creation of an interior volume. Horizontal panels at the bottom thicker to increase the strength of the structure. The connected horizontal structure has been replaced with thin strips at the top to avoid the whole structure clashing or being overcrowded.

Direction of the pyramids follows the form of the external surface towards the back. The concave form of the structure increase the amount of light in the pavilion when as the incident angle of sunlight closer to the horizon. Panels are larger at the bottom and decrease in size towards the top of the volume. Hollowed panels creates interactions between the interior and exterior. Size of the internal hollow decrease towards the bottom, generating smaller and sharper block of sunlight within the structure than the shadows created away from the structure.

The laser cutting file has been placed on the left.

600.00

The pt_unroll command in rhino would sometimes results in undesirable unrolled surfaces and this has to be manually fixed. The straight lines has been nested together to save printing time, although many of the curves and complex geometry has to be set alone. The whole unrolled file was then made 2d and joined to eliminate duplicate lines and saves cutting time. Some outline has been set to etch to avoid the material falling off the panel and results in taping.

Week Five

Grasshoper Script

Grid Manipulation.

The Script for boolean surface has been attached on this page. Apaert from the standard scripted fprovided in the workshop, I experimented the use of a range of point attrators to iterate the gird. I have also played with random variable as on the next page to create the final boolean cutter for my design. 3 random bases has been created in each unit and cuboids are created based on this random field. I manipulated the dimensions of these cuboids on a random seed to generate boxes with different dimensions at a specific range.

Cuboid Manipulation.

Normal Random Distribution.

No. of Cuboids per unit = 3

Dimensions shuffled.

Random seeds manipulated until satisfaction.


Week Five

Isometric

The slice has been chosen for 3d printing as it contains a good range of information for interpretations. The internal volume of this slice has also change from external open space to sheltered internal space. The cuboid boolean cutters blends seamlessly into the original cubic form, forming a unifying structure with a great deal of variety and randomness, allowing a great possibility for functions and circulations. Internal framed opening creates a threshold that guides the user’s movement, volume transferring from an open space to a more private one. The hollow at the top be interpreted as skylight to allow day lights to come into the structure, internal volume is vertically empathized. The hollow through the vertical boundary may be used as a balcony to create a connection between interior and exterior. Platform cut in different heights forms natural stairs or benches for individuals to sit or chat in group.

Task 01 Matrix A range of surface combination has been tested, and I have chosen two surfaces embracing each other to form a wide opening on one side and gradually narrows down towards the other end. Such way the structure will be able to interact with the external public space and welcomes individuals to explore. Three points attractors are picked to guide the panelling element pointing towards a certain direction. A combination of hollowed pyramids and triangles have been selected to get a number of lighting options throughout the day for people with different needs.

Dimensions of the cuboid has also been determined randomly at a specific range.
