Material DANGER Cause/ Consequence
PVC (Poly Vinyl Chloride)/ vinyl/pleather/artificial leather Emits pure chlorine gas when cut! Don't ever cut this material as it will ruin the optics, cause the metal of the machine to corrode, and ruin the motion control system
Thick ( >1mm ) Polycarbonate/ Lexan/ Makrolon Cut very
poorly,
discolor,
catch fire
Polycarbonate is often found as flat, sheet material. The
window of the laser cutter is made of Polycarbonate
because polycarbonate strongly absorbs infrared
radiation! This is the frequency of light the laser cutter
uses to cut materials, so it is very ineffective at cutting
polycarbonate. Polycarbonate is a poor choice for laser
cutting. You can generally tell if a material is polycarbonate because it will have a bluing agent that makes the sides of the material a dark charcoal blue color, or by how flexible it is. Acrylic is much more rigid.
ABS Emits cyanide
gas and tends
to melt
ABS does not cut well in a laser cutter. It tends to melt
rather than vaporize, and has a higher chance of catching
on fire and leaving behind melted gooey deposits on the
vector cutting grid. It also does not engrave well (again,
tends to melt).
HDPE/milk bottle plastic Catches fire
and melts
It melts. It gets gooey. Don't use it.
PolyStyrene Foam Catches fire It catches fire, it melts, and only thin pieces cut. This is
the #1 material that causes laser fires!!!
PolyPropylene Foam Catches fire Like PolyStyrene, it melts, catches fire, and the melted
drops continue to burn and turn into rock-hard drips and
pebbles.
Fiberglass Emits fumes It's a mix of two materials that cant' be cut. Glass (etch,
no cut) and epoxy resin (fumes)
Coated Carbon Fiber Emits noxious
fumes
A mix of two materials. Thin carbon fiber mat can be cut,
with some fraying - but not when coated.
Epoxy Resin Contains Chlorine, catches fire Epoxy is made with chlorine and will emit chlorine gas. Will also melt and catch fire
PETG Melts, gets gooey, offgasses PETG offgasses a white film that can get on the laser's optics and ruin it. Please do not melt your PETG scraps and use them in the laser
Unfired Ceramics Makes a huge mess Please just don't do it
Uncoated Metal Doesn't cut, Doesn't etch
