Which slicer do you use? It seems to be a known problem of cura.
- sokoloff 5y agoI use Cura. It’s across FDM printing techniques and is (somewhat) akin to the errors in subtractive manufacturing. Subtractive errors/inaccuracies tend to be of the type that remove too much material. Additive errors/inaccuracies tend to add material. My models for FDM often include a “hole size compensation” user parameter and I tweak it to introduce an offsetting bias in through-holes. (Non through holes tend to get heat-set brass inserts, which are more forgiving of the 0.1mm or less radial errors.)
- 2muchcoffeeman 5y agoYou can print a clearance tolerance test to see how accurate your printer is. I use a Prusa mk3s and as accurate as it is, at best my tolerance is 0.1mm. Enough to stop your parts fitting together. I normally build in a 0.2mm tolerance for close fitting parts.
- _carbyau_ 5y agoI have had the issue with both Cura and Simplify3D. For a circular hole, as far as I can tell the slicer commands the hotend path to trace the circle exactly, rather than tracing a slightly bigger circle to account for output thickness. I imagine if you were to use smaller nozzles the issue would be lesser, but not gone.
