Thick white material is the toughest. Like thick white denim or canvas requires a very slow cutting speed. Polyester seems to emit some kind of harmful gasses. I always ventilate the room, wear an n95 mask, run a HEPA filter nearby, and sit outside during and shortly after cutting pretty much anything, but especially polyester. I can't really think of what would not be cut by the laser, but I don't know anything about what fumes may be more or less harmful.
- dylan604 4y agoYeah, there's certain materials that the laser cutting community knows about that you just don't cut with a laser. One of the gasses produced is Hydrogen Cyanide Gas (HCN). PVC also produces nasty gas as well. Here's a more definitive list: https://laseruser.com/what-can-a-laser-cutter-cut/ https://laseruser.com/what-can-a-laser-cutter-cut/
- TaylorAlexander 4y agoAh good, polyester is okay! I mean, definitely do not breathe whatever it's putting out. The first time I cut it I did not wear a mask and my throat was immediately very sore.
- mike50 4y agoI think an organic vapor respirator is warranted but it's been a while since my training. Generally an N95 is for solid particle IIRC.
- TaylorAlexander 4y agoYeah makes sense! These days I basically just step outside while it’s cutting and let the room air out for a while before I return. I do have to check on it to make sure it hasn’t had an issue and for that I wear a mask but also basically hold my breath and then hop outside again as soon as I can.
