Laser-Compatible Materials Guide

Updated January 2026 · 8 min read

Choosing the right material determines 90% of how your finished piece will look and perform. After eight years of cutting thousands of orders, we have compiled this reference covering the materials we work with most often and a few you should avoid entirely.

Various acrylic and wood sheet materials stacked in a workshop

Wood

Wood is the most popular material we cut. The laser interacts differently depending on grain density, resin content, and moisture level.

Avoid: Treated lumber, pallet wood, and any plywood with phenolic glue (produces harmful fumes).

Acrylic

Cast acrylic cuts cleanly and produces a flame-polished edge that looks almost hand-finished. Extruded acrylic is cheaper but melts rather than vaporizes, leaving a rougher edge.

Avoid: Polycarbonate (Lexan). It does not cut cleanly with CO2 lasers and produces toxic chlorine gas.

Leather & Fabric

The laser seals edges as it cuts, preventing fraying on fabric and producing a clean, slightly darkened edge on vegetable-tanned leather.

Avoid: Chrome-tanned leather and PVC-based vinyl. Both release toxic fumes when heated.

Paper & Card

Paper is among the fastest materials to process. We can cut intricate designs that would be impossible with a craft knife.

Metals

Our fiber laser handles thin metals for marking, engraving, and light cutting.

Materials You Should Never Laser

  1. PVC or vinyl -- Releases hydrochloric acid gas. Damages the machine and endangers health.
  2. Polycarbonate -- Discolors, melts unevenly, produces toxic fumes.
  3. ABS plastic -- Tends to melt and catch fire rather than vaporize cleanly.
  4. Fiberglass & carbon fiber -- Releases hazardous particulates. Requires industrial filtration beyond our setup.
  5. Coated or treated metals -- Unknown coatings may contain chlorine or cyanide compounds.

Not Sure About Your Material?

Send us a sample or a product link. We will identify the composition, run a test cut, and let you know whether it is suitable for laser processing. There is no charge for material testing when you place an order.
