DIY Exhaust Fan Kit for Flashforge Creator 5 Pro

When printing non-engineering filamant like PLA, PETG, TPU, PLA-CF, the Flashforge Creator 5 Pro activates a "Adaptive Air Circulation" mode. In this mode, we observed that the exhausted air from the printer is unfiltered. As such, we explored ways to improve the cleanliness of the air we breadth while working around the Flashforge Creator 5 Pro.  In this process, we made our own DIY Exhaust Fan Kit for our Creator 5 Pro.

Our Creator 5 Pro Exhaust Fan Kit includes:

• 2 types of adaptor that easily fits over the exhaust fan of the Creator 5 Pro.

  • A "Plain Adaptor" for attaching our fixtures

  • A "Adaptor with Stator" for attaching our fixtures and accelerate exhaust air flow.

•  3 fixtures that can be connected to each of our adaptors.

  • A "Filter Fixture" for inserting a Creator 5 Pro filter to filter the outgoing exhaust air.

  • A "Hose Fixture" for connecting any ⌀80mm ventilation hose to route exhaust air to an external filter or to a window.

  • A "Blank Fixture" for sealing the exhaust fan outlet during Thermostatic Internal Circulation mode, i.e. when 3D printing engineering filaments. Because the exhaust fan is deactivated in this mode and the exhaust fan outlet is wide open, this fixture is intended to prevent convective or diffusive outflow of any chamber air from this opening.

Amendments:

• 15 Aug 2026 - Added a gasket for the Adaptor. For minimizing chamber air leak at the gap between adaptor and the printer's right side cover.
