To reduce microplastic and VOC pollution from 3D printing, I built a sealed enclosure for my A1mini with AMS using the case of an old gas water heater and some spare wood. It includes lighting and a filtration system with a PC fan and a 3M filter. I also enabled filament feeding through the AMS mounted outside the printer. The enclosure cost almost nothing, and now I can print with any filament without any fumes—right in my room.
