One of the joys of laser cutting is its versatility, but not every material belongs in a laser. Some cut cleanly, some mark well, and a few release harmful fumes or simply will not work. Knowing the difference matters for both results and safety.

The good and the no-go

Timber, plywood, acrylic, card, paper, leather and many plastics cut and engrave well on a CO2 laser, while metals are marked and engraved with a fibre laser. Certain materials, however, should never be lasered because they release dangerous fumes or damage the machine.

When in doubt, ask first rather than risk a hazardous reaction.

  • Great for laser: plywood, MDF, acrylic, card, leather, many plastics.
  • Metals: marked and engraved with a fibre laser.
  • Avoid entirely: PVC and other chlorine-containing plastics, which release harmful gas.
  • Always confirm unknown or coated materials before cutting.

Ask us if unsure

If you have an unusual material in mind, check with us before committing. We will confirm whether it can be laser cut or engraved safely and well.
