There will be consequences to cutting these materials due to the serious health & safety implications. There will be no exceptions to this list.
|Type||Material||Toxic Gas||Fire/Smoke||Burns/Melts||Damages Equipment||Notes|
|Fabric||Felt, Fleece (Wool)||Hydrogen Cyanide (HCN)|
|Artificial, Acetate, Nylon, Cellophane, Viscose, Rayon, Spandex, etc.||Hydrogen Cyanide (HCN)|
|Food||Any||Both||Both||Even cutting approved materials results in the laser cutters being an unsafe environment for food, in addition to the damage that laser cutting food could cause.|
|Metal||Any Unlisted||Optics, Motion-Control System||Our C02 laser cutters can etch certain coated metals; they cannot cut metal.|
|Plastic/Polymer||ABS (Stratasys 3D Prints)||Hydrogen Cyanide (HCN)||Fire||Both||Cutting Grid, Bed|
|Carbon Fiber||Hydrogen Cyanide (HCN)||Both||Both|
|Epoxy, Resin, Fiberglass, Ecoresin||Hydrogen Cyanide (HCN)||Both||Both|
|Polycarbonate, Lexan||Chlorine (Cl2)||Both||Both|
The window on the laser cutter is made from this due to its resistance against radiation and being laser-cut. The material will melt and turn brown instead of cutting, etching, or engraving.
|Polyethylene (HPDE, PETG), Tyvek, Polyester, Fleece (Artificial)||Formaldehyde (CH2O)||Fire||Both||Cutting Grid, Bed|
|Polytetrafluoroethylene (PFTE), Teflon||Carbonyl Fluoride (COF2), Fluoroform(CHF3)|
|Polyoxymethylene, Delrin||Formaldehyde (CH2O), Hydrogen Fluoride (HF)|
|Polypropylene||Fire||Both||Cutting Grid, Bed|
|Polyurethane||Hydrogen Cyanide (HCN)|
|PVC (polyvinyl chloride), Vinyl, Pleather/Faux Leather, PVB (polyvinyl butyrale), materials containing halogens||Chlorine (Cl2), Hydrogen Cyanide (HCN)||Optics, Motion-Control System|
Please note that the Co-op sells material that looks like acrylic but is made of PVC and styrene. There is an entire shelf of banned materials in the Co-op.
|Self-adhesive, or material with sticky or glue backing||Optics||Examples include cork tiles, thin wood laminate, acrylic tiles, and paper stickers.|
|Rubber, Elastomer||Carbonyl Fluoride (COF2),, Hydrogen Fluoride (HF)|
|Styrene, Polystyrene, foamboard, Foam Core, styrofoam, Depron foam, Gator foam||Benzene (C6H6)||Fire||Both||Optics||The main cause of laser cutter fires. Please note that the Co-op sells material that looks like acrylic but is made of PVC and styrene.|
|Wood*||Coniferous, Oily, Exotic||Both||Examples: pine, spruce, teak. Their hardness varies, so they can't be cut consistently.|
|MDF, HDF, Engineered||Formaldehyde (CH2O)||Both||Extreme charring.|
|Adhesive/Resin-Filled||Hydrogen Cyanide (HCN)||Both||Optics||Baltic Birch plywood is an example.|
*Some types of wood are approved, but the specific ones listed above are prohibited.
