Jesus Javier Vela: Week 9 Laser Cutting


Vertical View

Concept

     Thinking of the recurring wave of organically shaped buildings around the world, I decided to build an architectonic piece. Like Capital Gate tower, I wanted the side of my piece to contour diagonally towards the ground. Three pillars make the piece free-standing while other smaller pillars add support between sections of the piece.

Techniques

     Flatfab, a 2D to 3D fabrication design software was used to make the piece. I first drew the top-most section. Then I attached a support pillar to it. I used the revolve operation to create the other two support pillars. Next, I added the bottom-most section to the opposite end of the first support pillar. I had to make sure this section interconnected the all three pillars. Using a blend operation, ten more sections were generated (twelve sections, total). Once the piece was down, I downloaded the flattened slab geometry as a .obg file. I formatted the file in Rhino, extended lines to intersections, transforming text into objects, and reviewing that the dimensions were accurate. Unfortunately, I didn't save the .txt file, so the piece was lost. Hence, a .obj file could not be generated to render in Keyshot.

Materials

     Before I sent the piece for laser printing, I made two prototypes. First, I printed the file using copy paper. The thinness of the material made it impossible for the piece to be free-standing. Next, I made a prototype using card-stock. The material was thicker, so the piece was able to stand on its side. When I finally laser printed the file using cardboard, the piece was able to stand vertically as well as horizontally.
