Easy print TPU 5" propeller

thingiverse

Got a spark of creativity to see if creating TPU propellers is feasible. So started sketching it out in Fusion360. Moved forward with the design by prioritizing printability in the propeller's architecture. Attempted to craft an airfoil that would be somewhat practical.  Maximum overhang angle, necessary for printing without supports, dictates the propeller's pitch. It seems to be somewhere between 46 and 50. After printing some props, they came out perfectly balanced after cleaning the strings. However, some required a little trimming to achieve balance.

So there's only a 0.5g difference.  **2018-10-16** Update Second test flight: https://www.youtube.com/watch?v=S2zL7hnMeZo Propeller torture test: https://www.youtube.com/watch?v=KcdPLXUvPoQ This project appears to be somewhat successful, considering it started as a joke. My next plan is to find an aerodynamic expert who can help me strike a good balance between a superior airfoil and easy printability. If you know someone interested in this project, please let me know!
