Technical guides on 3D file conversion, STEP files, STL, 3MF and everything in between — written for engineers and makers who care about the details.
Export STEP from Fusion 360, convert to STL or 3MF locally — your IP never leaves your machine. Step-by-step for the complete workflow.
→Every other converter uploads your file to a server. Here's how WebAssembly makes local conversion possible — and how to verify it yourself.
→STL is 35 years old. 3MF was built for modern 3D printing. Units, scale, multi-material — here's what 3MF does better and why you should switch.
→53-part drone assembly returning an empty file? Here's exactly why it happens and how the Assembly Splitter delivers a ZIP of individual printable parts.
→You sculpted it in Blender or scanned it with photogrammetry. Now your file is OBJ and your slicer wants STL. Here's the fastest path with no upload.
