I'm still curious if it reduces noise on drones, though. Can 3d prints stand up well enough to be used as propellers, so someone could test it?

Yes, ABS is supposedly strong enough for that.

I wonder if we'll see a 3d printable version soon.

I'm thinking of putting it on the Mini 2 and seeing what happens.

Probably not without violating a patent.

I'm kinda sure that if he is not going to sell it they really don't care.

If you went around looking for patent and copyright violations on thingiverse you'd probably need to remove most of what they've got.

Yes, You are absolutely right. Anybody could try any shape for scientific experiments, but sell copies and distribution of 3d models prohibited.

Indeed. https://www.thingiverse.com/search?q=Sharrow&page=1&type=thi...

I wondered if this design is heavier for same lift? Might be part of the reason for moving development to boat propellers

Edit, to clarify: i refer here to 3D printed boat props, not for copters.

I'm considering this as well. I have an electrical outboard engine on my 24". 600W is way less stressing on the material than even small combustion engines.

I'll maybe try a 3D printed one next year. According to thingiverse, folks already successfully use printed props and the sharrow-design is there, as well, just need to adapt the mount and make sure the printer is up to it (i.e. convert from PLA to ABS, may have to get a new nozzle)

People in Ukraine print small props. But conventional design. For small electric engines good enough.
