WEEK08: molding and castingThis week we studied molding and casting. This method excels at rapidly prototyping precise structures in a variety of materials; better, the master molds can often be re-used for continued production. Taken a step further, as Aubrey demonstrates in his production of bee hexagons, one can even use finished products as new masters, allowing exponential growth of production capacity until defects propagate beyond an acceptable point. Our materials of choice this week were blue machinable wax, Oomoo silicone, and various plaster-based compounds for rock-like finished reproductions. Our assignment was simple: mill something, then cast it. Thanks to Tom and John for teaching us how to use the Desktop Shopbot, and to Graham for teaching us how to cast silicone, plaster, and low-temp alloys!
