Studies find 3D printers emit particles and VOCs linked to airway cell stress

Research cited on 3D printing safety shows filament printers release ultrafine particles and volatile organic compounds, with the EPA noting these can penetrate deep into the lungs. A 2026 test of 17 commercial filaments found ABS generally emitted more particles than PLA, though emissions varied by brand, nozzle temperature and additives. Separate lab tests exposing human airway cells to PLA and ABS printer emissions found signs of inflammation and cellular stress, while NIOSH warns uncured resin used in resin printers can cause skin reactions or asthma.

Bambu Lab's P2S 3D Printer Adds Smarter Airflow but Struggles to Contain ASA Fumes

A hands-on review of Bambu Lab's new P2S 3D printer finds it builds on the P1S and A1 with an enclosed chamber and an airflow system that switches between cooling PLA prints and retaining heat for tougher filaments like ASA and ABS. The reviewer notes that despite this design, fumes from ASA prints leaked around the door and seams rather than being fully filtered through the built-in carbon filter, requiring extra ventilation.
