==Things we can and cannot cut using the laser==

Things we '''can''' cut:
 +
* 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 www.mcmaster.com.
 +
** 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 www.mcmaster.com.
 +
** Teflon (PTFE, Polytetrafluoroethylene) — for a supplier, try www.mcmaster.com.
 +
** Woods (MDF, balsa, birch, poplar, red oak, cherry, holly, etc.) — for a supplier, try www.midwestproducts.com.
 +
 +
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

We have a Full Spectrum Engineering 40W Co2 Laser Cutter

Tetsu worked hard and started a Kickstarter project to get us a laser cutter for about $2000. We successfully promoted it enough to get people to generously donate to our cause, and now we have one!

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:
