Various Fabrication Projects
Over the course of the past three years at Ball State, I have been able to take part in several different seminars or independent studies over various topics within the realm of digital fabrication. The courses have dealt with rapid prototyping in 3D printing, laser cutting, CNC milling with MasterCAM, and introductions to Grasshopper and other parametric modeling options.
High Density Foam Mills
The first two projects highlighted here are from a seminar taught by Adam Buente and Kyle Perry of PROJECTiONE. The focus of the first project [High Density Foam Mills] was to create unique geometry in Rhino and Grasshopper and then relate that information into a milled form. Because I had previous experience with milling and fabrication, I tried to design my projects to use the paths of the machining process to help give an extra layer of intrigue and information to the final piece. The first attempt was simple lofted surface that used Grasshopper to create milling paths along the isocurves of the surface, creating larger or smaller scallops depending on the surface properties. The second machining project was heavily rooted in Grasshopper where the proximity of several attractor points created a point cloud for a voronoi. Information gathered from the voronoi cells was then relayed to how high and how far inward the cell linework was to be extruded. This created areas of high contrast on the surface and also allowed for several apertures to be created through the bottom of the foam surface.
Polycarb Hex-Grid Canopy
An earlier project for PROJECTiONE’s seminar required the use of the lasercutter to create a full scale installation in the College of Architecture and Planning. By using a series of attraction and repulsion points in Grasshopper controlled through proximity of doors and windows in the chosen site, a hex-grid was manipulated to create elongated hexagons, pulling to and from the set points. These manipulated hexagons were then truncated and extruded in the z-axis in the same manner that their original elongated shape was developed – proximity to the attraction and repulsion points. The end result of this was a series of polycarbonate, truncated hexagons that were larger and closer to the canopy’s bottom the further they were from two nearby doors, creating a shell-like effect leading people in and out of a classroom.
