"3D laser printer" probably means a Glowforge. Nobody else calls them that. Their documentation says "Lasers normally require some ventilation via a small tube out a nearby window. Our optional Air Filter that sits under Glowforge and ventilates using HEPA filters and charcoal, meaning no outside ventilation is required." That won't do much if you cut something that emits carbon monoxide when heated. That includes some common plastics, styrene being one.
There are lots of things you don't want to cut on a laser cutter unless
you're cutting under an inert gas, or at least nitrogen. Polycarbonate, any of the chlorinated plastics (PVC, some synthetic leather), styrenes, and polyethylene, for example. ABS melts, and Fiberglas's glass component won't cut. Acrylics cut very well. Delrin cuts OK. Wood and cloth are OK. Techshop is careful to teach people about this.
TechShop's laser cutters have compressed air coming in, a big exhaust hose going out, and a fire extinguisher nearby. TechShop has an ad slogan, "Don't try this at home. Do it at TechShop". There's something to be said for that when you're using industrial-strength tools.
In addition to the two people, their two cats died. Operating these things in a closed room is a really bad idea.
