Just means that slicers now a days seem to handle bad meshes much better than 10 or 15+ yrs ago.
But I’m not really a fan of allowing slicers to fix bad meshes. A bad mesh is a bad mesh, and slicing a bad mesh will likely lead to anomalies down the line – some of which ppl prob wont care about, but ignorance is bliss I suppose.
My preference is to someday force the slicer to slice specific types of meshes (isopods), rather than creating the proverbial cookie cutter profiles.
5-axis printing will be fun some day too, but that’s still not very common.
