My experience with Fusion for 3d printing is basically: looks great, is fast but my models fail to print correctly for some reason. Can't wait for freecad to get a useable UI, because it is works fairly well for printing despite its UX shortcomings

My email's in my profile. If you have some examples of what didn't work well for you, I'm happy to have a look and see if I can get you unstuck and headed to success. If it's a calibration issue on the printer (parts print, but are slightly the wrong size), I can recommend Teaching Tech's intro here and here: https://teachingtechyt.github.io/calibration.html https://teachingtechyt.github.io/calibration.html https://www.youtube.com/watch?v=rp3r921DBGI https://www.youtube.com/watch?v=rp3r921DBGI If it's in the Fusion->STL stage, I might be able to be of more help. If it's in the STL->physical part stage, the above or other 3DP videos might help.

  I wiped the computer used for this whole ago, but the models are probably on the cloud somewhere. My problem was that the produced STL had some errors that were hard to see but definitely showed up in prints, for example a wall section could be missing.

    are you certain the STL stage had the error? In the 3dp discords i'm a part of it seems that i'm continually reminding everyone that slicer features are usually the culprit. Features like 'detect thin walls', 'ensure vertical thickness' and 'extra perimeters if needed' can and will very quickly ruin a print where the STL is error-free. That said, one can accomodate these features by modifying the STL so that the slicer transformation occurs in such a way that allows a usable product, but as far as where the error is introduced, 9 times out of 10 it's the slicer. What should happen is that the slicer should err out to the user when the shape of the end product is predicted to be radically different than the request, but I haven't ran into such features yet. Most slicers just happily try to print stuff that is physically impossible to do, and might be radically different than the shape of the STL -- usually resulting in a plate of spaghetti if you're using an FDM machine.

    Your slicing software should warn you if the model is non-manifold. https://www.instructables.com/id/Non-manifolds-Your-Worst-3D-Printing-Nightmare/ https://www.instructables.com/id/Non-manifolds-Your-Worst-3D...

      Yeah, but there question is why fusion360 created such files. Similar designs in other tools worked just fine. I've some years of experience with CAD and know often what causes such issues but in the case of fusion360 I just couldn't figure out why this happened - in sometimes extremely simple models. I haven't used fusion360 for about a year so maybe they have fixed the bugs now.
