Oversized Parts / Dimensional Aaccuracy

Recommended Posts

Posted · Oversized Parts / Dimensional Aaccuracy



I'm having problems with either CURA or my ultimaker S5 and UM3 printers printing parts oversized, for instance a dimension modelled at 19mm is actually coming out as 19.28mm, a dimension dimensioned at 6.36mm comes out as 6.78mm. This means nothing fits together and sliding surfaces just jam. I'm trying to develop spacecraft mechanisms and trial them with 3d printed parts, but it's just not working and in fact the metal prototype parts are being delivered before I can get the plastic models working.
I'm using 0.4 nozzles, mostly standard settings.

I also have access to a stratasys and makerbot method X, both of which are printing my parts more accuracy than the Ultimakers are.


Is there a simple setting to tune the size of parts, obviously scale won't work. I am no 3d printing guru and I have very little time, I just need them to work.


Thanks people
