3D printed Axial Fan Test Bench


Image 1: 3D printed air flow test bench. Measures RPM, flow rate, pump head and power.

The test bench has been 3d printed. There are 4 unique duct sections to print. There's a holder for a 3DRobotics pitot tube, 2 static pressure ports on either side of the fan and the EDF housing I'll be printing will have an RPM sensor embedded in. These will allow me to measure flow rate, rpm and the head across the fan. I have a Watt meter which I can read off power for now, but I'd like to get a power transducer to read these for signal with my Arduino Uno.

Excellent job, The design looks really great just because of using 3d print technology..
