Materials You Should NEVER Use with a CO₂ Laser Cutter
Using a CO₂ laser cutter with certain materials can releasetoxic gases, corrosive fumes, or damage the machine. Below is a list of materials that are strictly forbidden:
Material
Reason
PVC (Polyvinyl Chloride)
Releases chlorine gas (highly toxic) and hydrochloric acid fumes, which are dangerous to humans and corrosive to optics and machine parts
Polycarbonate (PC)
Difficult to cut and emits phenol and bisphenol A (toxic gases) when burned
ABS Plastic
Emits acrid smoke and releases cyanide compounds, and burns unevenly
Polypropylene Foam (EPP)
Highly flammable, produces thick smoke and toxic gases
Fiberglass / Carbon Fiber
Can damage the optics and release fine particles and toxic fumes
PTFE (Teflon)
Emits carbon tetrafluoride and hydrogen fluoride, which are extremely toxic
Galvanized Metal / Zinc-coated Materials
Cutting releases zinc fumes, which can cause "metal fume fever" and damage the machine
Chlorine-based Compounds
Such as chlorinated rubber or some composites — release toxic chlorine gas
Lead-containing Materials / Painted or Coated Surfaces
Heating releases lead vapor or other toxic heavy metals
Polyurethane Foams (PU Foam)
Highly flammable and releases toxic smoke, such as isocyanates
Materials to Use with Caution or Only with Proper Knowledge:
Aluminum, Copper, and Other Reflective Metals: Low absorption of CO₂ laser; risk of beam reflection damaging the laser.
Leather: Some leathers are chrome-tanned, which emit toxic gases when cut.
Painted or Coated Surfaces: Unknown coatings may release toxic fumes when heated.
Common Materials Safe for CO₂ Laser Cutting:
Wood (e.g., plywood, MDF)
Acrylic (PMMA)
Cardboard, paper
Fabrics, plant-tanned leather
Some plastics (e.g., PE, PP)
Safety Tips:
If you are unsure about a material:
Check the Material Safety Data Sheet (MSDS)
Consult your supplier or laser manufacturer
Perform a small test cut in a well-ventilated area with proper exhaust
