Yeah, in my lab we prohibited cutting anything with chlorine, including PVC and polycarbonate.

The results are really bad anyways, it melts and burns. I'm curious though, can you get good cutting of polycarbonate using an inert gas shield? That would be interesting.

CNC zone reports that cutting polycarbonate on higher power lasers under nitrogen can be made to work, but it's touchy.[1] The plastic tends to melt rather than cut. Pre-freezing the material is suggested.

Polycarbonate has no chlorine.
