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.
Yes, they still work if they are 3d printed and you can even find files online for them such as this
It’s been done a lot, but its kinda pointless as any noise improvements from the shape are obliterated by the bad surface finish.
I saw someone 3D print a toroidal prop on YouTube. They tested it and it was 10 times louder than the normal but high quality manufactured propellers. So it would have to be made with a much more precise 3D printing process I think. Link for a laugh 😆
Certainly can. But you want to print them in a specific orientation to improve strength & aerodynamics
