Printer Air Filter by jagoosw

Last crawled date: 3 years, 3 months ago

I quickly knocked together this air filter for my Ender 5, replacing one of the components to my enclosure (https://medium.com/@jagosw/cheap-heated-enclosure-for-creality-ender-5-70-c-for-50-76c9e7dfd225) when I smelt the disgusting smell ABS makes. So far I'm unsure as to its efficacy but I will test when I have time (probably with some kind of air quality filter/particulate counter). The filter could also be mounted on the frame, or another printer, with no enclosure but would probably be even less effective.
To complete the filter you will also need:
A piece of some kind of filter media, I used a piece of a H13 HEPA bag filter but you could improvise
2xM4x12mm and 4xM5x12mm bolts and 2xM4 T-nuts
80mm 12/24V fan, I used a 12V one and a buck converter - https://amzn.to/3cOZEHJ (affiliate)
Rocker switch that fits in the hole at the top
Once you've wired the fan to your printers power supply trap the filter between the pieces and bolt them together, this was fairly challenging and took a while but I think all bolts are needed for a good seal.
I think this could do with a) a more powerful fan and b) the fan on the other side of the plastic so it sucks into the filter better instead of blowing which I think causes leaking round the sides.
Disclaimer: this is in no way a good or verifiable filter and you should use all usual precautions such as ventilation when printing with toxic filaments.
