Does it work to make a 3dprinted harmonic drive ?
indeed not bad at all !
I've developed a few weeks ago this design of harmonic drive. The generative wave is done with a gear done in flexible TPU. it works pretty well, it's powerful. For the next version I'll make the bearing holder arm shorter to reduce effort on the motor. At the moment it's really good enough to start my first developments in the 5 axis theme.
you can find the 3d files on my github account, everything is modelized with FreeCAD, it's free and opensource.

I am curious what benfit does it offer having a gear like that?
Explain to me in a word that 5 years old can understand
Harmonic drive?
which is the reduction ratio ?
😮 🔝🔝🔝
Why does it sound like I’m playing wangan midnight @ round 1
Fill with a mineral oil to reduce light friction and you could besr heavier loads depending on the thickness of each printed gear.
what's the benefits if this design??
Song?
Why there is a tpu gear part?
🙌🙌🙌
Epic
Couldn’t you get the same effect with a planetary gear system? And it would last longer as well.
What is this used for?
