 +====Material====
 +
 +Always check materials list BEFORE attempting to cut/engrave a material. If unsure contact IW Staff.
 +
 +__**Allowed Materials**__
 +
 +Plastics:
 +  * ABS (acrylonitrile butadiene styrene)
 +  * Acrylic (also known as Plexiglas, Lucite, PMMA)
 +  * Delrin (POM, acetal) — **Must use nitrogen assist when cutting delrin**
 +  * Kapton tape (Polyimide)
 +  * Mylar (polyester)
 +  * Nylon (melts badly)
 +  * PDMS
 +  * PETG (polyethylene terephthalate glycol)
 +  * Polypropylene (PP) — melts somewhat
 +  * Styrene
 +  * Two-tone acrylic — top color different than core material
 +
 +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, etc supplier try: ​mcmaster.com​)
 +  * Woods(MDF, balsa, birch, poplar, red oak, cherry, holly, etc. supplier try: ​midwestproducts.com​)
 +
 +__Prohibited Material__
 +  * **Metals**​ (our laser cutters are not powerful enough nor setup to cut through metals and attempting to do so could damage the machine)
 +    * Metals (cannot be engraved however a certain type of paint/tape which chemically bonds with the metal may be used to mark materials)
 +  * **Polycarbonate**​ (PC, Lexan) — Lexan creates large amounts of fumes
 +  * **Teflon**​ (PTFE, Polytetrafluoroethylene) – cutting creates Fluorine gas
 +  * __**Any material containing chlorine**__
 +    * **PVC** (Cintra) — contains chlorine
 +    * **Vinyl** — contains chlorine
 +  ***HDPE​**: "milk bottle" plastic. It gets gooey, melts and catches on fire.
 +  ***Epoxy**
 +  ***Glass​** — you can engrave glass, but trying to cut it will cause cracking or breakage
 +  ***Fiberglass**
 +  ***Printed circuit board​** (FR4 and other material types)
 +  ***Carbon Fiber**

 +====Functional Engraving Recipes====
 +For users looking to cut acrylic at different depths, these different cut depths were tested at different power settings. Data courtesy of Ph.D. student Sanghun Jee on a Trotec 60W CO2 laser cutter. Thank you Sanghun!
