It’s amazing that the world is still seeing innovation on something as simple as a propeller, the limits of science are so vast!
Curious. Could you 3d print a propeller or does it demand some sort of higher quality manufacturing process? For a DIY drone project slapping some toroidal propellers just to test it out seems doable.
It’s been done a lot, but its kinda pointless as any noise improvements from the shape are obliterated by the bad surface finish.
Certainly can. But you want to print them in a specific orientation to improve strength & aerodynamics
