I am under the impression that pulleys will wear down over time and the teeth will start to decay but this is my best option given my time constraint (Class Project Due Date).
What do you guys think about 3D printing both motor and wheel pulleys with an aluminum motor mount? Is this a huge waste of my time by chance?
I assume a few people have given this a go with mixed results and I would love to hear them! Any harsh criticism welcome.
Wheel pulley can certainly be 3D printed, you just have to choose right material…
this guy makes them from ABS+
I don’t know much about 3d printing but I would use fiber-reinforced nylon…there are sometopics about this already…just try to search…
For a Motor I would use steel pulley, 3D printed would wore out quickly (by my opinion)
PETG works too for the wheel pulley. Have a hundred miles on mine so far with no wear. I think the motor pulley might not work for long, but those are cheap to buy in metal.
For the wheel pulley they work great, not so much on the motor, since you have few tooth in mesh with the belt the forces that the teeth has to endure is way higher
My 3D printed motor pulley lasted a couple kilometers until a teeth broke apart, on other way the wheel one has more than 500Km so far and only now I’m beginning to see wear
Both printed on ABS, other material have better wear resistance and should last longer
