Foam: diode, CO2 and fiber laser compatibility

Manufacturers disagree on foam. xTool and Monport list foam for CO2 cutting and do not give a foam type. FSL and xTool support list polystyrene foam as a material that catches fire.

No one-pass cut depth is listed for this material on the laser machines page.

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.
