- 1. PVC (Polyvinyl Chloride) & Vinyl
- 2. ABS (Acrylonitrile Butadiene Styrene)
- 3. Fiberglass
- 4. Polycarbonate (Lexan)
- 5. HDPE (High-Density Polyethylene)
- 6. Polystyrene & Foam (EPS, XPS)
- 7. Coated Carbon Fiber
- 8. Teflon (PTFE)

- 12. MDF with Formaldehyde Resin
When using a laser cutter or engraver, certain materials can release toxic fumes, catch fire, or damage the machine. Here are some unsafe materials to avoid:
1. PVC (Polyvinyl Chloride) & Vinyl
Releases chlorine gas (toxic and corrosive), which can damage the laser optics and harm your lungs.
2. ABS (Acrylonitrile Butadiene Styrene)
Melts easily and releases cyanide gas, which is extremely hazardous.
3. Fiberglass
Contains glass fibers that can damage the laser lens and emit harmful fumes.
4. Polycarbonate (Lexan)
Tends to discolor, catch fire, and releases toxic fumes. Thin PC may cut poorly.
5. HDPE (High-Density Polyethylene)
Melts and can create a sticky mess, potentially igniting.
6. Polystyrene & Foam (EPS, XPS)
Can catch fire easily and release toxic styrene fumes.
7. Coated Carbon Fiber
The resin releases toxic fumes, and the fibers can damage the machine.
8. Teflon (PTFE)
Releases hydrogen fluoride gas, which is highly toxic and corrosive.
9. Glued or Painted Materials
Unknown coatings may emit harmful fumes when burned.
10. Beryllium Oxide
Found in some electronics; releases deadly fumes when lasered.
11. Certain Rubbers & Neoprene
Can produce chlorine gas and melt unevenly.
12. MDF with Formaldehyde Resin
Some MDF contains toxic binders that release formaldehyde when lasered.
