This study tested different control methods, including an enclosure. The enclosure with a high-efficiency particulate air (HEPA) filter had the highest removal effectiveness (99.95%) of nanoparticles.
Basically you can say:
- Small particles and gaseous (Volatile organic compound - VOCs) are emitted during 3D printing
- these emissions can be harmful if inhaled
- higher temperature results in higher emission
- ABS probably more harmful than PLA
--> recommendation:
- print in separated, ventilated room
