Would it be possible to add a feature to the preform software where it will show in some way shape or form either features that will not print due to being too small, or where a print will not be able to continue due to wall sections being too small?
I’m wondering how small you want to go :P.
I printed a gear which was 5mm in diameter, and that worked fine. Would you want to go even smaller?
However, I do agree that it would be great to have an option in Prefrom to see if the wall thickness is thick enough to print without any problems. Of course they do state that wallthickness has to be 300 microns or more!
