Critical Reading: Kolerevic B. 2003. Architecture in the Digital Age

Kolerevic described three fundamental types 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)

Kolevic discussed about subtractive, additive and formative fabrication techniques. Subtractive fabrication is a fabrication technique that involves removal of volume from the object, like carving.

Additive fabrication is a fabrication technique where materials are incrementally layered to create a solid object, one practice would be the 3D Printing using polymere and many other materials.

Formative fabrication uses mechanical, heat or steam energies to form the materials, where the materials can be processed, reshaped or deformed with the process.

Computer Numeric Controlled fabrication or often called CNC could be a great potential for parametric modelling as they can design buildings with precision through digital fabrication.

SURFACE AND WAFFLE STRUCTURE Surface Creation

The script above is basically the Loft Creator script and also the panelling script. The left part is where the lofts were being created through selections of 16 combinations of number slider, into two lofts. The right hand side script contains numbers of panels that are being used in the final model of the waffle. Different panels are being combined onto one surface by using cull pattern and merge script.

SURFACE AND WAFFLE STRUCTURE Surface Creation

The process of creating the visual script begins with creating a box, 150x150mm that will contains our lofts.

The Lofts itself were created using the edge selector, that will select edges from the box. After the loft were created, it comes to the creation of the panelling script, where “Morph3D” is used. A Rhino modelled panels were referenced into the grasshopper script and panelled onto the surface.

SURFACE AND WAFFLE STRUCTURE Laser Cutting

In the process of laser cutting, I decided to not tape my panels with paper tape, as most of the panels would be damaged by the tape, therefore I used Etch on several edge that should have been Cut. They helped me get a clean net without damage.

Matrix and Possibilities

The matrices shows the journey and processes of creating the surface and waffle structure. The first step was to select which lofts to use. I did create a waffle structure but was not really satisfied with it and therefore created another waffle structure which is waffle 2.2. I created 6 panel iterations and chose 4 from the 6 for the final combinations of panels. After creating the ombinations of panels, I observed the effect of the point attractor to my panels and determine its location and magnitude.

SURFACE AND WAFFLE STRUCTURE Photography of Model

The abstracted directions of my panels is what took my interest. The 4 triangular pyramid panels and also the 2 triangular pyramid panels created an effect that emphasize alteration of heights. Not only alteration of heights, it also created an effect where its directions are abstracted and it creates an interesting abstracted direction, even with the use of attractor points.

As my main concept when choosing this loft was as if the two surface are pulling each other, stretching outwards, the panels emphasized that effect and created a strong feeling visually.

Visual Scripting of Parametric Model

The above script shows how did the box and its cellulose grids were formed. It uses two point attractor and one grid attractor to form such cellulose grids, and in the end each grid points were used to be the location where the geometries are formed, carving through the bounding box to create the Solid and Void Model.

11

SOLID AND VOID Surface Creation

The first picture was the first result and the first step of learning how to create irregularly sized geometries inside the bounding box. As can be seen the geometry being used was sphere, and the sphere would carve the intersection of its volume with the bounding box volume. The second picture was my final boolean model, in which I used scaled Platonic Icosahedron in substitute to the sphere, and created such effect. It was critical to first learn how simple geometry would go when booleaned onto the box, and then try to create a more complex geometries to boolean from the box.

SOLID AND VOID Isometric view

Both Isometrics Volume were made using Platonic Icosahedron being booleaned into the bounding box.

The First Isometric used scaled platonic icosahedrons that make it possible to obtain such Boolean Geometries.

The model addresses the effect of porosity and permeability of itself through all of the holes being made by the geometry booleans. These permeability and porosity led to the extraction of such beautiful Boolean model that expresses a completely different feeling than the bigger version of it.

Matrix and Possibilities

Geometry Boolean

Task B Matrix The first row of matrices are the number of division, where I ended up using 3 and 4 division inside the bounding box, because 2 is too few and 5 is too many. The Point Attractors and Grid Attractor final values were attained through many trials. The Geometry Booleans I picked used Platonic Icosahedron on both, but for the 4.3 I used “ScaleNU� to stretch the geometries.

SOLID AND VOID

Photography of Model

From my 3D Prints, the effect that I was trying to achieve was to create a “Cave� like landscape where there are entrances and also irregularly shaped ceilings such as those in my models. I was also trying to develop models with the formation of connection between the ground plane and the ceiling, where those things also act as supports.

Appendix

Process

This is my first attempt on constructing the laser cut model of the waffle. I used PVA Glue and also brush to glue the joints of the waffle. It appears that the curving is not as interesting as I thought, and that is why I created another one with a stronger concept and a better form.

18

Appendix Process

Before I submit a laser cut job for my panels, I tested several prototypes of my panels, to know whether to print it mirrored or not, to not show the burn marks. I also tried several panels and make sure that every panels are able to be constructed later.
