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 approach to fabrication are: Subtractive fabrication, Additivie fabrication, and Formative fabrication Subtraction fabrication is removal specific volume from a given soild material. This processes through chemically or mechanically. CNC milling machines operate by milling away in two-dimensional x-y axial cutting as well as moving in z axis to cut in three-dimensions. Additive fabrication is works by adding a layer over a layer of series of cut-intersection of the specified model. One of approach is using polymers that turns solid when exposed to laser light. Formative fabrication is the reshaping and deforming a given material to the desire shape. This can be done through application of heat and force to materials such as metal and plastic. These fabrications perform under the CNC instructions which are generated from software which model is created. It calculates and determines the motion, feed-rate, and changes of the tools within the fabrication machine. This allow designeres to expend on the potential of fabrication with the comfort of generating CNC instruction through various softwares. however, designers still require to consider the limitations and the scope of these technical fabrications.

Panelling Exploration

Vavrous surfaces were created using different sets of edges of the bouding box. Then these surfaces were further explored by changing the indexs of the points along the edges. The dynamics, twisting and relationship between the two surfaces were studied;and the final design was furhter developed while considering the fabrication of the model and its ability to stand up-right.

Week Four Panels & Waffle

Panelling on the leftside is a protruding panel which also highlight the direction which the surface curves into. It has opening on one side of the panel which changes the visual connection between the interior and the exterior as the viewer travels around the structure.

The waffle structre contains a large volume in the center with the structure covering the top of the structure due to the twisting and the variying height of the two surfaces. This creates a potential for a undercover area for the internal space of the waffle.

The surface on the right as a combination of 2d and 3d panels. the perforation on 2d panels allow visual connection when looking at one side, however, the 3d panel hides the 2d panels while revealing the perforations on the opposite andgle. The panels seems almost kinetic with the change in form while the visual connectivity remains consistent.

Week Four

As untaping the masking tape for the ivory card is very difficult, Some edges were etched so that all the pieces remain on the paper without the need of masking tape.

Laser Cutting

However, untaping on the surface was very easy for the mounting board. Through the process of submitting lasercut file, it was discovered that hidden lines can be used to cut dashed lines,

Week Five

Use of attractor point to manipulate grid

changing domain number of grid

Volume of grid was experimented by changing the domain number from 3 to 5, and the spacing between the three sections of the bounding box. The effect of attraction point on the grid centroid were also explored. The main focus in the development of the model was on the exploration of different geometry and the iterations in scaling of a brep, with the use of attractor point to generate various scale.

Week Five

Isometric

Through the different iteration of geometry and scale, interesting factors were discorvered. These include creation of: various shape and size of opening from different cut sections of one geometry, interesting textures that gradually change in form, platforms and steps from change in scale and the relationship between the multiples of spaces created. For the final design, these explorations were incorporated while considering the visual connectivity and the threashold. Due to the flat base surface, series of platforms and steps were created, which gradually ascends as it travels towards the interior of the model. Various size of space were created due to the scaling effect, which are all joined with small openings, which again decreases in size as it gets further into the interior.

Task 01 Matrix For the surface, iteration 1.3 was selected and further developed for the final model. From 3.1, the direction of the curves creates by the triangle inspired the concept of the design. The final design incorporated the panels from 3.3 and was further developed. One surface is made of the panel from 3.3 with a opening on one side that allows for visual connectivity from one angle but not from another. The second surface is combination of 2D perforated panel and 3D panel with an openging. This allows for change in form but consistency in visual connectivity as one viewer travels from one point to another.

Task 02 Matrix While exploring the effects of the scaling attractor points, the manipualted gird points of ascending spacing has related will with the gradual change of scaling of the geometry. Therefore 1.1 and 1.4 was collaborated together with the scaling attracttion of 2.4. The geometry of 3.1 was selected as it provided three interesting aspect of the exploration: creation of various levels and steps, gradually changing pattern facade and different shape of openings for all other surface of the model.
