Re: pic: 2175 Wheel v2

The uPrint only has one res .010, we pay close attention to how the part is grown in relation to the loads we think we see in our parts.

We also try not to run any maching ops on the part as it stresses the parts and creates cracks, we do not clean up the hex with a broach. So we run test parts to look for best fit. For the hex we printed a small ring with the hex with different tolerances. We do this with any part requiring a mating surface. Plus it's quick the test pieces usually print in 10-20 min.

Our bot jumping the bridge was a big deal for us. It proved that our plastic drive train parts could handle the unexpected. Plus it was just darn cool.

I have no experience with the other brands on the market so I can not compare.

I have found printing parts saves us time, effort and weight , but we know expect failure so we try to print spares. But have had to use many.
