Fume filter for 3D printers

thingiverse

Human absorbs pollutants when printing ABS. This holder allows pieces of activated carbon filter foam to be secured against the inlet of a small centrifugal blower (BFB0712H). Install inside the enclosure of a 3D printer to capture microfine particles and VOCs when printing ABS. Instead of venting outside, this setup simply recirculates air within the enclosure. Since ABS requires a warm environment, this keeps the heat inside. You can attach the entire assembly to the inside of the enclosure with M4 bolts. I used two layers of the following filter foam. The template file makes it easy to cut the correct size circles with a hobby knife. Replace the filter pieces when you start noticing an ABS printing smell again.
