The filter can be printed for single or dual fan operation. A single fan should be used for continuous filtration. Dual fans can be used for large format printers or as an exhaust filter.

Materials

Material choice is guided by enclosure operating temperature.

  • CF-ASA, CF-ABS: >80C, <95C
  • ASA: >60C
  • ABS: >45C. Avoid with active heaters.
  • PETG: <45C or chamber floor. PETG filters should be considered a temporary solution (expected to fail with time). Do not use with active heaters.
