Fiberglass and epoxy: diode, CO2 and fiber laser compatibility
FSL lists fiberglass as a material that cannot be cut and that gives off fumes. FSL also states that epoxy-coated items and cast epoxy resin must not be used in a laser cutter. No other manufacturer linked here covers fiberglass.
Listed as unsafe. One or more laser manufacturers list this material as one to keep out of a laser. Their statements are in the table below.

One-pass cut depth
No one-pass cut depth is listed for this material on the laser machines page.
Notes
- FSL is the only manufacturer linked here that covers fiberglass.
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.
