How to convert SAT to STL
- Add your .SAT file - drop it in the box above or click to browse.
- Convert it to .STL in a few seconds.
- Download your new .STL file.
What to expect
- Tessellation is irreversible - smooth ACIS surfaces become flat triangles, so keep the original
.satif you need to re-edit the geometry. - Higher mesh quality produces a larger file; a medium or fine preset is sufficient for most FDM prints.
- If the source
.sathas open shells or invalid faces, the resulting.stlmay have holes - inspect and repair before slicing.
Frequently asked questions
Will converting SAT to STL reduce quality?
Yes, in one specific way: exact curved surfaces are replaced by flat triangles. You control how fine that mesh is at export, but smooth mathematical surfaces cannot be recovered from the STL.
What mesh quality should I choose for 3D printing?
The default or Fine preset works for most FDM prints; only push to maximum quality for very small parts with intricate surface detail.
My slicer reports errors after importing the STL - what now?
The source
.sat may have had open shells or non-manifold geometry. Re-open it in CAD Assistant or Fusion 360, check for warnings, repair if needed, and re-export.Can I convert STL back to SAT?
Not accurately - STL is a triangle mesh and SAT is exact B-rep geometry. Converting back requires specialist reverse-engineering software and produces only an approximation.
