There are some materials you should not engrave or cut with a laser becuase of their chemical make-up. Processing these materials creates dangerous gases or dust. These materials include:
- Leather and artificial leather that contains chromium (VI)
- Carbon fibers (Carbon)
- Polyvinyl chloride (PVC)
- Polyvinyl butyrale (PVB)
- Polytetrafluoroethylenes (PTFE /Teflon)
- Beryllium oxide
- Any materials containing halogens (fluorine, chlorine, bromine, iodine and astatine), epoxy or phenolic resins
Care should be taken with the following materials:
Be especially careful when processing "flame-retardant" materials because they often include of bromine. For flame-retardant materials, it is best to ask the manufacturer about the exact ingredients.
If the aforementioned materials are laser engraved or laser cut, dusts or gases may be produced that endanger the laser user or the functionality of the laser machine. For this reason, we do not recommend using these materials.
