Long Term Use of 3-D Printers Could be Hazardous

Scientists at the Georgia Institute of Technology and Underwriters Laboratories have shown that 3-D printers emit fine and ultrafine particles demonstrated to have significant harmful effects on cells that line the respiratory tract. Emissions vary depending on the printer and filament, including the types of particles, number of particles released during printing, and the toxicity of the particles. Professional users and consumers should consider using filaments demonstrated to have lower particle emissions during printing (such as PLA), ensuring 3D printers are in well ventilated spaces, and limiting time spent in close proximity to operating printers.
