Usage

Don't use the following materials :

  • PVC plastic of other material containing chlorine,

  • Natural Rubber, silicon rubber is ok
  • Not recommended Polycarbonate (also known as Lexan, it produces a ugly edge and smokes like crazy).

If you are not sure you can use this diagram to identify the material

ALWAYS keep an eye on your job when the laser is working. Don't leave it unattended, it could catch fire.
