Print not fitting to dimension - any hints?

Recommended Posts

Hi Daid!

Thank you for reply!

Understud - depending on shape, geometry and "heat flow" the shrinkage of a particular part of the model is different to anoter part of the same model - so can not be considered via just a scaling factor in cura.

So best idea would be to print it once, measure it on several points, calculate the deviation, adjust the model itself by the calculated factors and print it a second time with hopefully fitting dimensions...

Right?

Yes, that usually is the method. There are some general rules that usually work. Like 3mm screw holes, if you want lose 3mm screws in there you use 3.2mm holes, 3mm holes for "screw them in" and 2.8mm for "need to use threading tools"

Generally "parts that need to fit together" you keep 0.2mm clearance.

But these rules do not always work.
