Quoted from Colsond3:As far as I know, you need a digital cutter or some other apparatus to cut polycarbonate, as Zitt said above. PETG is the standard today, so that's probably the route I'm going. And I'm making a few extras.
Correct, We tried cutting PolyCarb many years ago with a CO2 100+W laser with special Argon air assist... and it was slow going and didn't work right for many parts. PolyCarb seems to melt instead of vaporizing which means the "cut line" glues itself back together as it cuts.
PETG is generally ok on the CO2 lasers... although I don't have a lot of experience with it.
