[QUOTE="CoolHandLuke, post: 334879, member: 4850"] polycarbonate is stiffer than pmma, but suffers from being difficult to machine. if heat builds on the tool, the material will melt into the tool, instantly set, and poof, you broke a tool. polycarbonate needs new machine templates to run smoothly because you absolutely must mitigate heat either by milling wet, or with a lot of air and super speed. multistratum is worth it. good stiff teeth that don't wear easy (unless you forget the varnish) and can be milled quite thin.
