I am looking for a casting company who can cast (in 18k gold) parts
that I get from a 3-D printer made by 3-D Systems, called the
InVision HR 3-D Printer. This is a machine that prints out a CAD
file in an acrylic photopolymer material which can be invested and
burned out, but I have heard that it may need a special burnout
cycle. Anyone know anything about this?
