Though this is marketed as a "laser printer" its most likely a laser cutter. Glow forge was the first I know of to start this stupid fad of calling them printers to be associated with the 3D printer market.
Laser cutters burn materials at high energy and need to be properly vented.
Exactly. This was more like having an unventilated fireplace in the house, except it makes much less smoke so you don't realize just how dangerous it is.
