3D Printer Air Filtration System-Compact (AFS-C) HEPA & Carbon filter

3D Printer Air Filtration System-Compact (AFS-C)

The Air Filtration System was initially designed for use in 3D printers. It is intended for recirculation filtration in a printer with a built-in or external enclosure.

• Featuring a HEPA filter and Activated Carbon the filter can 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 HEPA or Activated Carbon, but most do not feature both. That's why I came up with this design.

Recommended Print settings

Material: Preferably ABS*, PETG works too
Infil: 40%
Extrusion width: 0.4mm
Wall line count: 4
Solid top/bottom layer:4/5
Support: on
Above 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 is already perfect, scaling will only be required if it doesn't fit. ]

Bill of materials

Required materials (hardware)

I 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 appreciate it if you could give feedback about the filter and that will allow me to make improvements as well as determine the demand for such a product.
