Polycarbonate: diode, CO2 and fiber laser compatibility

Epilog states that thin polycarbonate can be cut on its CO2 lasers but discolors, and xTool support states the same about thin sheet. FSL lists polycarbonate thicker than 1 mm as a material that cuts poorly and catches fire. Boss Laser states that it burns and does not mark cleanly.

Notes

Fumes

Laser cutting and engraving give off fumes. The machine's manual has the venting rules for that machine. The fume and room lookup compares a machine's exhaust airflow with fume extractor airflow.
