Safety Instructions
General
- ALWAYS SETUP AND TURN ON the gas extractor and chiller (on the left side both switches)
- always wear safety gear (glasses)
- you don't want you material to melt -> higher chance for FIRE when stringing
- check the gas/steam emission when cutting
- if to much gas/steam, adjust the settings (less power or more speed)
- know where the fire extinguisher is
- never leave laser while lasering and check from time to time/no headphones
No Go Materials
Don't use following materials:
| Material | DANGER!! |
|---|---|
| PVC (Poly Vinyl Chlorid)/vinyl/pleather/artifical leather | Emits chlorine gas when cut ruin optics and corodes metal! |
| Thick (>1mm) Polycarbonate/Lexan | Cuts very poorly, discolors, CATCHES FIRE!!! long stringy clouds on cutting -> will ruin optics and mechanics |
| ABS (Acrylonitrile butadiene styrene) | Melts instead of vaporize / Hydrogen Cyanide Gas on cutting -> UNSAFE |
| HDPE/ milk bottle plastic | Catches fire and melts |
| PolyStyrene/PolyPropylene Foam | CATCHES FIRE VERY EASILY! |
| Epoxy | can't cut -> burns/ smokes Cyanide!! |
| Fiberglass | Emits fumes (glass can only be etched and epoxy only smokes) |
| Coated Carbon Fiber | emits noxious fumes!! (carbon fiber can be cut, but not when coated) |
| Any Food | Not food-safe -> many toxic gases where in the laser for a longer time |
| Material With Sticky Glue Backing | Coats/ cracks lens when CUT; also hard to remove from the lens! |
