[dorkbotsea-blabber] Phlatprinter - CNC for cutting foam sheets

[Steve Greenfield]

Yes, they have CNC foam cutters that work in that way. Radio control model builders use them to make wings. Others use them for cutting out architectural shapes for stage sets and signs.

Google for "cnc hot wire foam".

A while ago I was looking at some large models someone was building  
up out of layers of relatively thick foam (I think this was at a  
dorkbot meeting a year or two ago?). It occurred to me that one could  
build a CNC X-Y hot-wire cutter that was able to control the angle of  
the cut, with a lot less trouble than building a full 5- or 6-DOF  
machine, and still be able to make pretty complicated 3d shapes by  
stacking the cut layers.
