Slicer STL Repair

I opened a FreeCAD STL file in Slicer 2.4.2 MacBook Pro running OS 11.6.7. Prusa Slicer indicated “Auto repaired 6 errors”. Does that mean my Prusa GCode export of the STL file should 3D print OK on the i3 MK3?

Also, I have come across some info suggesting that Prusa Slicer could be prompted to run repairs by clicking on the icon of a triangle with an exclamation point in it or selecting some menu option. Were these features related to n earlier version of the Slicer because I couldn't find the menu option and no combination of hovering over, clicking, right clicking command clicking etc. I tried did anything with the triangle icon, file name in the Expert tab of the software window or on the model itself seemed to bring up any repair options.

RE: Slicer STL Repair

It's very easy to produce wonky .stl files if you try, and even if you don't try.  😉

I've found some of the things that do it will be trying to edit objects that have chamfers/fillets without first undoing said ornamentation, or doing a boolean cut with an object that is not a true solid.

PrusaSlicer can repair some, not all, mesh errors transparently.  My experience is that if you slice it in PS and it produces a preview that looks sane, it will usually print as expected.

I've also found that Cura is, in many cases, more forgiving with wonky .stl files than is PS.

Don't beat yourself up. It happens to all of us.
