Question: are fumes from 3d printer toxic?
Answer: According to a 2016 study on emissions from filament material used in 3D printers, ABS and Nylon emit high levels of styrene which is suspected to be a carcinogen. Styrene is known to cause headaches, drowsiness, and fatigue. This study also suggests that PLA is a safe material when it comes to 3D printing and fumes.
