SUAFT 120 Introduction

SUAFT 120 is an activated carbon and HEPA filter for 3D printer enclosures. SUAFTs are designed to be simple, cheap, and efficient; v3 builds on v1 with a sleeker design and easier disassembly.

Goals

  1. Be simple and efficient.
  2. Be easy to build.
  3. Be cheap to source.

SUAFT

Bill of Materials

The filter can be printed for single or dual fan operation. Use a single fan assembly for compact printers (200x200 bed or smaller) or ones with limited free space. High flow and larger volume printers should use dual fans.

Materials

Material choice is guided by enclosure operating temperature.

  • CF-ASA, CF-ABS: >80C
  • 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.
