Rubber

Nina Idzerda, Emily Kirwan, Robert Nealan, and David Spittler

Starting off with a map of San Luis Obispo, we plotted specific landmarks and roadways. From there we manipulated and abstracted our points, creating surfaces. This surface was created and determined by the relationship (closeness) of each point to the main landmarked points (done so with Grasshopper). The main roadways determined our lines grid. Here we replicated and offset them, trying to see if, when casted, they can form some sort of structural support through their randomly varying intersections and density.. RhinoCam was then used to rapidly CNC molds out of high density foam insulation panels, which were subsequently coated with various release agents (petroleum, mold wax, liquid mold release, PAM cooking oil) in an attempt to isolate a preferred release-agent solution.

Using liquid latex, mold release and vaseline first, we painted the liquid latex over the foam forms in varying thicknesses. About four layers later, using a hair dryer to quickly dry each layer, we were able to successfully peel off the rubber. After seeing the color of the latex, for the next two molds we decided to dye the latex.

Our team was interested in rubber because of its flexibility and liquid base, so we chose fields that would test its viscosity, ability to be removed once fully cured, and structural properties (if any) once removed from the solid mold.
