Bacterial Viral Filter for CPAP Machines
A filter used by ventilators for filtering out dust and moisture particles. Original part consists of two pieces melted together, and filtering membrane inside. The membrane is just a piece of cloth and fibre, it does not have any complex structures HEPA-filters and such.

Reference photos:
- Part should be completely sealable (possibly with the help of superglue of medical silicone)
- Part should contain special filter inside
The 3D-printed part that consists of 2 pieces. Parts have very small tolerances and are connected using mechanical lock to make it re-usable. Requires additional sealant for complete air-tightness.
Recommended print settings
- Infill rate: 70% or higher
- Lower part to be printed from inlet upwards. Recommended to use 3mm brim for stability
- Because of steep angles use higher print temperature to improve filament adhesion
Monolithic part that has filter inserted during print process. Does not require extra sealant. Not reusable. Requires editing the generated G-code to insert "Pause printing" instruction at the beginning of arbitrary layer between position Z46 and Z47 Possible G-code instructions are "M0", "M1" or "M600" - please consult your firmware documentation for exact code
