Gap in assembly

[castoretpolux 0]

Hi!

I'd like to know what is the minimum gap between to parts of a assembly in a pivoting relationship when we print them together at the same time with an Ultimaker 2.

Thx!

Pivoting? If you are talking about a bearing (any place where 2 parts slide across each other such as a hinge) then...

For vertical walls you can be extremely close - around .1mm or .2mm in the model should work okay - you have to experiment. It depends on printing temperature (lower is better) and fans (more is better) and material (PLA needs more of a gap than higher glass-temp materials).

However for vertical separation you probably need at least .2mm if not more.

Also you might need to turn off all the "fix horrible" settings (expert tab) or it might combine 2 pieces into one part and print right over the gap.
