Guide · STEP file → STL
STEP file to STL — instantly.
Got a STEP file from a client, a colleague or your own CAD export, and need an STL for your slicer? Drop it in — it converts locally, in your browser, in under a second.
Open the STEP file → STL converter →Which CAD packages export STEP?
- SolidWorks (File → Save As → STEP)
- Autodesk Fusion 360 (Export → STEP)
- Autodesk Inventor
- FreeCAD
- Onshape
- PTC Creo, Siemens NX, CATIA
What about the other way?
STL → STEP is a different operation (re-building B-Rep from a mesh) and isn't covered by this tool. For that, you'll need parametric CAD software like Fusion 360 or FreeCAD.
