Printing tolerances #21

Closed androiddrew closed 4 years ago

androiddrew commented 4 years ago

Hey @jakkra does your design have enough tolerance in the CAD model for direct printing or would I need to account for shrinkage in my slicer?

jakkra commented 4 years ago

You should not need to shrink parts in your slicer, some parts are a tight fit by design. You may need to sand some parts a bit for perfect fit. Of course it depends a bit on printer calibration also, I print on a Prusa mk3.

So my recommendation is to print as is and then sand if needed, should not be too much.

Ok, sounds great. I was referring to the shrinkage of the plastic as it cools. So printing at 101% scale, which roughly accounts for PLA shrinkage.

I think you should print at 100%, I have printed all parts in PLA also so it's designed for that.
