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.
Covers/enclosures seem useful to capture the emissions. Some studies saw reduction of around 90%.
I wrote a review article summarising studies about emissions during 3D printing: https://doi.org/10.1016/j.atmosenv.2022.119501 (Should be open-access soon)
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
