We have a Epilog Fusion 32 60 watt

Lots of people worked on this (sorry this was before I was here so I don't know all the details).

Our Model

    • 32" x 20" cutting table
    • 60w Co2 Laser
    • Safety Interlocks
    • Air assist
    • and Awesome

Things we can and cannot cut using the laser (NEEDS UPDATE)

Things we can cut: [1]

  • Plastics:
    • ABS (acrylonitrile butadiene styrene)
    • Acrylic (also known as Plexiglas, Lucite, PMMA)
    • Polycarbonate (PC, Lexan) — Beware the fumes on this one, they can get pretty bad.
    • Delrin (POM, acetal) — for a supplier, try
    • Kapton tape (Polyimide)
    • Mylar (polyester)
    • PETG (polyethylene terephthalate glycol)
    • Polyethylene (PE) — melts badly
    • Polypropylene (PP) — melts somewhat
    • Styrene
    • Two-tone acrylic — top color different than core material, usually for custom instrumentation panels, signs, and plaques.
  • Foam:
    • Depron foam — often used for RC planes.
    • EPM
    • Gator foam — foam core gets burned and eaten away compared to the top and bottom hard shell.
  • Other:
    • Cloths (leather, suede, felt, hemp, cotton)
    • Magnetic sheets
    • Papers
    • Rubbers (neoprene) — for a supplier, try
    • Teflon (PTFE, Polytetrafluoroethylene) — for a supplier, try
    • Woods (MDF, balsa, birch, poplar, red oak, cherry, holly, etc.) — for a supplier, try

Things we CANNOT/DO NOT cut:

  • Metals
  • Any material containing chlorine
  • PVC (Cintra) — contains chlorine
  • Vinyl — contains chlorine
  • Fiberglass
  • Printed circuit board (FR4 and other material types)
  • Carbon fiber
  • Nylon — melts badly


Laser Cutter Settings

The laser cutter has two settings that are mainly used: Power and Speed. These are determined by the type and thickness of material and the type and thickness of the desired cut. This is a table of suggestions based on what lab members have found by trial and error; so they may or may not work for you. If you have something new, go with what's most like what you're trying to cut and experiment from there.

There are a few things to remember when using the laser cutter:

  • Never cut PVC. If you don't know what it is, do your best to research it or ask someone. Using PVC **WILL** Damage the laser cutter.
  • The "Laser Test" button is ALWAYS live. Do not press it with the lid open.
  • DO NOT go over 15mA on the current adjustment knob. This will kill the laser tube quickly.
  • If anything seems out of place (strange noises, burn marks, laser is not cutting and power meter is moving, water or air is not running properly) STOP. Ask someone what to do.

Extruded Acrylic 3mm 10mA 30% This is a test, change this to actual settings.
