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)

Additive fabrication involves creating a form by adding material to each other in a â€˜layer-by-layerâ€™ format. It is used for 3D printing, where layers of ceramic powder are stuck together to create volumes. Formative fabrication involves manipulating and warping materials to create forms. This is done taking a base material and utilising mechanics, bending, heat and steam to transform it. Subtractive fabrication involves the removal of material from a solid to create indents, parts and forms. For example, laser cutting uses a beam to slice or etch into material. But laser cutting can only work in two dimensional planes. CNC fabrication can extend the boundaries of current prefabrication in construction. With software able to code machines which operate in up to 5 axes to create complex surfaces, such as doubly curved geometry and intricate construction pieces.

Week Three

Surface Creation

Using the script, I adjusted the variable to achieve surfaces that worked well together. From left to right, the first one I used similar surface shapes but rotated, unfortunately these surfaces could not physically stand. The second surface would be able to stand and there were some interesting spaces. The third iteration was using a reflected parallelogram where there was a very small gap. The final iteration was the one I chose and I will discuss my reasoning later.

Week Four Panels & Waffle

The panels I used were a â€˜two peaked mountainâ€™ form on one side and panels with aperture on the other side. The apertures are designed to let light pass out of the structure from the inside and also provide a water feature for when there is rain.

The waffle structure follows my surface iteration. Utilising a large open space to capture the light and restrict it down to a narrow opening on the other side. The waffle structure had to be rotated on one of the surfaces otherwise the waffle would not have been buildable.

Creating the laser cut was a fairly straight forward process. By laying out the pieces of the waffle shapes in 2D using grasshopper before baking the pieces and packing them together so that they could share edges to shorten the amount of time for the sheet to be laser cut. The panels were created by baking them out of grasshopper and then unrolling them and adding tabs before I submit the file.

Week Five

Boolean Solid Creation

Creating the boolean script was relatively straight forward, utilising the multiple attractors to transform the gird and test out different volumes to boolean. In the workshop I tried the basic sphere before I tried the same with triangles, then I used more complex pyramid shapes and a point attractor. The final iteration on the right was my design choice, where I used a weaver bird command to make pyramids on triangular pyramids as well as a cross like volume which extended horizontally and vertically, I also applied point attractors with different scales for each.

Week Five

Isometric

When I designed this boolean model I realised that when it was in the full box that most of the interesting spaces were on the inside of the box. So I made sure when selecting which part to 3D print, that I chose the part with the most angular surfaces. The main idea behind it was that the sunlight passes through apertures on the side of the structure and skylights on the roof and rebounds off the semi-reflective surfaces, as to not blind the visitors, but to allow the entire interior to be lit by the reflective light. The cross shapes were meant to provide passageways to smaller spaces within the structure for visitors, to try to emulate the effect of a mirror room. If the whole box were to be selected, then the skylights and apertures would be prone to water exposure inside the structure, but the angled surfaces would provide drainage and the sharp edges would cause a â€˜drippingâ€™ water feature which would increase the amount of reflections within the structure.

Task 01 Matrix The matrix shows my process of choice for my waffle and panel structure. Using the 1.4 surfaces due to the large space to small crack spatial quality and the looming wave like structure that towers over the viewer, I then decided upon using separate point attractors from 2.2 to manipulate my surface patterns. My choice of patterns were 3D, one side being the two peaked mountain to emphasise the looming nature of the structure and the aperture panels to allow for the penetration of light through and outside the structure as well as both panels providing a way to drain the structure and water features. Angled apertures translate light from the buildings interior to exterior. Could potentially allow for water/drip feature utilising rain runoff.

Full pavilion could be a box structure with emphasis on the internal features and reflections. With the apertures acting as thresholds to entice passers-by to explore inside.

Apertures or â€˜Skylightsâ€™ allow for light to enter the structure.

Task 02 Matrix In the first row I experimented with the different attractor types, of which I chose 1.1 as the others provided cube geometry that was too heavily transformed and would have resulted in some of the shape being incomprehensible. The second row involves experimenting with different shapes and there effects through different transformations. I decided on the combination of the cross shape to link spaces together and the pyramid on pyramid volumes from 2.2 and 2.4. The final row had the attractors for the scale of the shapes, where I used the circular one for the cross to make the edge crosses larger and I used the first point attractor to transform the pyramid shapes. Rectangular openings allow for small passageways to access the more enclosed spaces and also allow a small space for light to shine through.

Angled surfaces could utilise reflective material to reflect light onto other surfaces. Creating a mirror room effect lighting the interior spaces of the structure which otherwise would be dark

Pointed areas allow for the reflected light to penetrate the structure at all angles.

Surface form emerges like a wave from the ground. Looming over the viewer creating overpowering shadows and intimidating vertices from the triangular panels.

Narrow end creates thoroughfare with light either â€˜shining through the crackâ€™. Or creating narrow streams of light through the interior of the structure.
