3D Printer Air Filtration System-Compact (AFS-C) [Currently BETA]The Air Filtration System was initially designed for use in 3D printers. It is intended for recirculation filtration either in a printer with a built-in enclosure or an external enclosure.Featuring a HEPA filter and Activated Carbon the filter is able to remove VOC and particular matters(pm 2.5 & pm 10).It can be converted to a HEPA-only or Activated Carbon-only filter for specific use cases.The filter cartridge can quickly be taken out and replaced.Because of the small form factor, it can be mounted on a wide range of machines.I've tried to make the form factor of the filter as small and as compact as possible. It can be printed on small printers like a Voron 0 (120x120).Many designs out there feature a HEPA or Activated Carbon but most of them do not feature both, that's why I came up with this design.Recommended Print settingsMaterial: Preferably ABS*, PETG works tooInfil: 40%Extrusion width: 0.4mmWall line count: 4Solid top/bottom layer:4/5Support: onAbove are the main things that need to be changed, other settings are dependent on the printer model and personal preferences.*Printing the parts in ABS, PETG (or even PLA) will work, but ABS is recommended for enclosed printers or high-heat environments. Scaling the parts up by 1-5% can help to compensate for shrinkage when printing with ABS. (102% is what I am using) [Except for spacers as their size are already perfect, scaling will only be required if it doesn't fit. ]Printed parts1x Base mount1x Base cover1x Filter Mount or Filter Mount Max1x Filter Cover or Filter Cover Max1x Separator4x Spacers(Optional) 1x Air Duct 1x Mount for your printer (in development, if you'd like to help out join the Discord server!)Bill of materialsRequired materials (hardware)HEPA filter (18x90x10mm)1Activated Carbon Pellets (not acid washed)15015 blower fan (GDSTIME DualBall Bearing is what I use and recommend)2Magnet 6x3 12M3x5x4 Heatset Insert (voron specs)15M3x5 fasteners (BHCS) 9M3X20 fasteners (BHCS)4I understand that the HEPA filter is pretty hard to get, it is a custom size that I cut out of a big piece of lab-tested HEPA filter sourced from Singapore. I am currently considering selling kits but am unsure of the demand. Currently, the easiest way to do it is to find a HEPA filter that you can cut into size I would really appreciate it if you can give feedback about the filter and that will allow me to make improvements as well as determine the demand for such a product. Check out the GitHub of this project for build guide and more information.
