Can 3D Printed Gears Measure Up?

When it comes to hobbyist creations, gears are usually a part of the equation for many mechanical devices—from racecars to clocks, puzzles, and more. The question is, how do 3D printed gears hold up? And the answer is: it depends. While they may not ever be able to hold up in terms of strength to traditional metal gears, with the proper printer, materials, and know-how, you can make some amazing 3D printed gears that will blow everyone away, as well as offering durability and surprisingly high performance.

I've been printing spur gears with Taulman Alloy 910. The resulting gears are incredibly strong and durable. They could easily be used for medium duty production mechanisms. If you're printing gears, I highly recommend it.

how are you printing that stuff ?

I found it almost impossible to use.

And as far as the 'article' goes.
No information on gears. The entire thing boils down to: 'you can make gears and if you make them right they'll probably work'.
Talk about a 10 minute piece knocked off by someone with bugger all knowlege on the subject.

Actually it's more like "NEVER". You can do plastic gears. Yes. They're dirt cheap. Yes. They may work in short-lived low effort, low speed applications. Yes.
If you intend anything else... well, don't.

again depends on the material and usage.
