Laser Safe Materials
- ABS (Acrylonitrile Butadiene Styrene)
- Acrylic (Als known as Plexiglas, Lucite, PMMA)
- Delrin (POM, Acetal)
- High Density Polyethylene (HDPE)- Melts Badly
- Kapton Tape (Polyimide)
- Mylar (Polyester)
- Nylon – Melts Badly
- Polyethylene Terephthalate Glycol (PETG)
- Polyethylene – Melts Badly
- Polypropylene – Melts somewhat
- Two-Toned Acrylic – two-layer colored acrylic, top layer is a different color than the base color. Used for signs, plaques, and instrumentation panels.
- Depron – Often used for RC planes
- Ethylene Vinyl Acetate (EVA)
- Gator Foam – Hard shell of gator foam does well but, the foam core gets burned and eaten away.
Textiles & Others:
- Cloth- Leathers, suede, felt, hemp, cotton
- Paper – Cardstock, cardboard,
- Rubber – These can only be used if they do not contain chlorine Teflon (PTFE,
- Woods – MDF, balsam, birch, poplar, red oak, cherry, holly, etc.
Materials that can’t or should not be cut with a laser:
- Metals (exceptions of etching = Using TherMark. Cutting = HP models “Oxygen/Air assist”
- Polycarbonate (PC, Lexan) due to the fumes.
- Any material containing chlorine
- PVC (Cintra) – contains chlorine
- Vinyl – contains chlorine
HP (High Pressure) materials include all the above guidelines and as listed:
- Stainless steel up to 18 gauge
- Mild steel up to 20 gauge
- Thicker and denser woods
