Here’s a list from a site via google search.
Plastics:
- ABS (acrylonitrile butadiene styrene)
- Acrylic (also known as Plexiglas, Lucite, PMMA)
- Delrin (POM, acetal) – for a supplier, try McMaster-Carr.
- High density polyethylene (HDPE) – melts badly
- Kapton tape (Polyimide)
- Mylar (polyester)
- Nylon – melts badly
- PETG (polyethylene terephthalate glycol)
- Polyethylene (PE) – melts badly
- Polypropylene (PP) – melts somewhat
- Styrene
- Two-tone acrylic – top color different than core material, usually for custom instrumentation panels, signs, and plaques.

We do not or cannot cut the following materials:
- Polycarbonate (PC, Lexan) – we stopped cutting Lexan due to the fumes.
- Any material containing chlorine
- PVC (Cintra) – contains chlorine
- Vinyl – contains chlorine
- Glass – we can engrave glass, but we cannot cut it.
- Fiberglass
- Printed circuit board (FR4 and other material types)
- Carbon fiber
- High-density polyethylene (HDPE) thicker than 1/16" – We are unable to cut HDPE thicker than 1/16", and HDPE of any thickness melts badly when laser cut.
