Here, a very large chunk of RenShape sitting on the CNC router, getting the first facing phase of a LOT of cutting. It’s a distant cousin to what you might think styrofoam is. It’s a urethane foam. This stuff ain’t cheap. It was almost $500, plus shipping.  It does cut really nicely though - a hell of a lot better than MDF, and is still cheaper than aluminum, so I guess for this it makes sense. According to company specs… “RenShape 440 is a medium-low density polyurethane modeling and styling board. Used for master models, CNC styling models, prototypes, and visual models. RenShape 440 machines easily at fast cutting speeds, finishes to a good surface with excellent edge definition and produces very little tool wear.”  Anyway, we’re turning it in to a model for some more top secret blah blah blah I can’t say what thing, which is a shame, because the last one I did was one of the finest examples of CNC cutting we’ve done in the shop to date. This one will probably be much the same.
