Modern slicers have natively supported STEP for years. They give you true circular arcs, eliminate tessellation artifacts, and allow anyone to actually modify the geometry in CAD without dealing with a broken triangular mesh. Scanned models and organic sculpts need meshes, but 90% of functional prints on Printables and MakerWorld are designed in CAD. Why are we still exporting to a 1987 format that discards design intent? What is keeping you on mesh (STL/3MF) exports in 2026?   submitted by   /u/Giorgist   to   r/3Dprinting [link]   [comments]
