Printing moving parts

Recommended Posts

Posted · Printing moving parts

Can someone give me some pointers for the modelling requirements, and maybe print settings for printing moving parts in a single print. I'll be using UM1 with PLA

thanks

Geoff

"Moving parts" is a very broad description. What are you trying to do more specifically?

Things like hinges, say for a 2mm diameter cylinder, what diameter hole would be required to get it moving easily?

For the print-in-place hinge on this thing I used a 0.3mm clearance which seems to work well for a loose and free joint. On this one I used just under 0.2mm.

For tighter fits I go down to 0.1mm and in general I tend to use around 0.2mm. But it depends :) When you have holes that are printed on a vertical wall the holes tends to not come out perfectly circular so that is something to watch out for.

If it makes you feel any better I almost never get it perfect on the first try with a new model, it will usually take at least one test print to make sure things are working as intended.
