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 fundamental fabrication techniques include: additive, subtractive and formative. Additive is the incremental formation of volumetric silhouette from layers which can be cured by light, heat of chemical, depending on the material. (3D Printing). Subtractive is the removal of material from a mass or volume. (CNC) Formative is based on deformation or reshaping of materials through appropriate stresses such as compression, tension, shear or combined stresses.

CNC can reproduce parametric models more accurately and efficiently, In terms of both geometry and measurements. However, CNC fabrication can be restricted the axis movement of the technology.

Week Three

Surface Creation

By increasing the index number to 20, a more interesting variation can be generated. Before baking out each surface, a general analysis was conducted by observing the space bound or enclosed by the two surfaces, this is in regards to the flexibility of the space in different orientations as well as the qualities of openings, voids and interaction between the two surfaces.

Week Four Panels & Waffle

Informed perforations on both panels allows light permeability, in a controlled and gentle manner.

A curvilinear waffle structure provides contrast with the geometric panels.

During day time, it can act as a canvas to receive sunlight and cast dynamic shadows.

The waffle twists gradually to form dark ripples of light and shadow

At night, it can radiate with internal lightings.

Week Four

Laser Cutting

The key constraint is the size of the geometry, as size decreases the burn marks from the laser increases, especially where lines intersect.

Moreover, the slender ends on both the left and rght waffle structure results in a weak structure. It required multiple applications of PVA to strengthen the material.

The large triangular plate on the z-axis waffle was deigned as the base plate for the waffle, since the surface stands on one single point on one side.

Offset Srf

Transformation

Waffle

The boolean form is based on the contrast between the undulating surface form and the horizontality and particularity of the waffle structure. The key process was scripting the parametric surfaces using graph mapper, as it was the main parameter that changes the form of the design. The rest of the script streamlines the waffle making process when the desired surfaces are baked out and linked.

Week Five

Isometric

The boolean difference of the rectangular prism and the parametric surface contour waffle, provokes a monolithic array of openings that varies in height.

The boolean union of the parametric surface contour waffle generated a mountainous structure.

The in between spaces are dynamic and completely open The inversion of positive and negative spaces empasises on the horizontality and perpendicularity of the displaced and reoriented forms.

The cantilevered blocks of continous curves provide shelter for the space below.

The section cut exposes the curvilinear roof within the monolithic openings, which is retained from the boolean difference

Task 01 Matrix The iterations focused on transformative qualities of space as the surfaces are orientated in different directions. The waffle also has a transformative quality, from the slender curved ends to the larger geometric frames.

Iteration 3 was selected to be further developed, because it had the most flexible and adaptable spaces. The two surfaces are interdependent and the waffle provides to the link for structural integrity, thereby, forming n active dialogue between the elements of the design.

Task 02 Matrix The iterations focused on the undulating mountainous forms, with transformation and adaptable spatial qualities when orientated in different directions. The two contour waffles are perpendicular to each other to emphasis the horizontality of the space, while the undulating verticality conveys dynamics and movement.

Iteration 2 was selected to be further developed, because it had a good balance between voids and masses. The boolean difference and union also created interesting openings between the masses and formed waffle like patterns.
