Introduction
This page is a list of materials that can be cut or engraved on the 'NEW' Nottinghack A0 laser cutter from Just Add Sharks, along with information on cutting speeds and power settings. Other useful information is also provided.
You can see a reasonably complete list of what is laser safe here and here.
The values on this page have been tested, but are guidelines. Always stay with the laser when it is running, and use your common sense!
DO NOT CUT
- Vinyl, PVC - Contains chlorine, which generates glass and metal damaging acid fumes when burned!
- Polycarbonate - clear polycarbonate looks just like acrylic!
- Anything that produces fumes, e.g. glued woods (except laser-safe MDF/ply), many types of plastic.
- Anything you're not sure about. Check the websites here and here, email [1] for advice or ask on the Google group.
