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)

According to Kolerevic, the three fundamental type of fabrication are as follows: subtractive, additive and formative. Subtractive fabrication is the specified removal of a volume from a material via a milling process. These can be electro-, chemically- or mechanicallyreductive processes; and can be either axially, surface or volume constrained. In contrast, additive fabrication is the piling of numerous two-dimensional layers to form the desired outcome, hence it is also called layered manufacturing. On the other hand, formative fabrication does not need to manipulate the mass; as it uses external forces to either restrict or deform the material into desired form, such as stressing a material past its limit to permanently deform it. There is no doubt that CNC grants the potential to produce precise geometries that are otherwise difficult or impossible to be done by hand. Coupled with parametric modelling; allows for mass-prototyping, mass-customisation which can lead to the mass-manufacturing of buildings as visualised by Le Corbusier.

Week Three

Surface Creation

The process of scripting via Grasshopper is done exactly same as the procedure shown in the workshop. The top script is of manipulating the surface via the selection on index on four respective axis contained within the 150x150x150 mm box while the bottom script is the paneling scrip to array objects onto the surfaces. The four iterations on the right is an attempt to explore the effect of varying axis and the possibilities of creating a waffle structure via parametric design.

Week Four Panels & Waffle

The final panelled surface is [3.4] which is a combination of [3.1] as the fore panel and [3.2] as the rear panel. The panels are designed to

The waffle is designed to create various surface conditions to manipulate the openings on the panels. The front of the waffle twists as it moves upwards, scattering the light in different directions. The back is designed to be relatively flat to direct light with the directional panels.

B1

Through the use of Grasshopper script obtained via the workshop, it was easy to bake out the template of the waffle. However, extra culling of index has to be done with unwanted components. The panels on the other hand was smooth once an appropriate shape and angle was found. Then it was just a matter of joining and unrolling the surfaces into 2D template. Last, all template was lablled and placed onto a template file. Double checking of the file was made to make sure each line is in the appropriate layer as intended and fix any mis-


Week Five

The boolean script is almost identical to the one shown in the workshop with minor changes applied for a more mathematic and precise designing. Attractor points and curves were constructed within Grasshopper instead of importing from Rhino. After testing with various shapes, it is settled with this diamond-like shape (Platonic Octohedron) with the Grasshopper plugin: Lunchbox. The four iterations on the right is split into two direction of attractor, the top two is backwards attracted while the bottom two is forwards attracted. These were then combined and booleaned out to create more complicated hollows from simpler ones.

Week Five

Isometric

The design process began with experimenting with various shapes, from the simple sphere shown in the workshop to the more complicated shapes in the Lunchbox Grasshopper plugin. It was last decided to use the diamond-like (Platonic Octohedron) to array out grids of objects. Next, these grids of diamonds were overlayed together to create more complex hollows in the 150x150x150 mm cube. As different grid intersectes into each other to create directed openings that is formed from the long, sharp tips of the diamond. Thus, creating opening that directs light through the hollowed out spaces within the cube. The isometric to the left is chosen as the final iteration as it fully explores the concept of directional openings. The area to the left is a semi-public space that offers security for closing off the area except the entry. The right area has various directed openings; light is funneled down through two openings and a strip of opening at the middle of the structure. Thus leaving the right area as a lit up public space.

Task 01 Matrix From the lofts, [1.3] is the most ideal as it offers a mild, controlled change of surface unlike the extreme [1.2] and flat [1.1]. Moving onto the second row, [1.3] was rotated 180 degrees to have a better presentation of the twisted surface. Of the four sets of attraction, [2.2] was selected as it best fits with the final paneling step which resulted in [3.4].

Task 02 Matrix From the first row, [1.3] was chosen as it created the best arranged grid. This was then developed as the size of the object was manipulated through the use of attractors. These simple iterations were then overlayed onto each other into more ones on the third row. The three times overlayed [3.4] was at last chosen since it creates the most directional varied openings.

Laying out the prototype templates to confirm the process of constructing the waffle.

After attaching one row of vertical components to some horizontal components to have some stability of the structure; it is then flipped over and the rest of the horizontal components were attached.

Prototyping

Top: again, laying out the panels to confirm the construction process.

The complete prototype, the intended sharp edges were erased due to the delamination and the connection of panel to structure was loose due to glue being streched while setting.

Bottom: sharp edges tends to burst and delaminate while folding due to the etched folding lines

Appendix Product

A look at the completed final model which has much cleaner lines and folds due to the switch to cut dashed lines for the fold.

The pass through of light creates an array of dazzle within the internal space framed by the waffle structure.
