How to convert SKP to STL
- Add your .SKP 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
- The model must be a solid closed group - check Entity Info in SketchUp for "Solid Group" or "Solid Component" before exporting, or slicers will report holes.
- STL stores geometry only; colors, textures, and materials are not transferred.
- STL has no unit field - set model units before exporting to avoid the file appearing at the wrong scale in a slicer.
Frequently asked questions
Can I convert SKP to STL for free?
Yes - SketchUp Free exports STL with a free Trimble account, and the converter on this page is also free.
Why does my slicer report holes or a non-manifold mesh?
The SketchUp geometry has gaps; select the object, check Entity Info, and fix any non-solid geometry before re-exporting.
Will the scale be correct after converting?
It should be if units are consistent - set the model unit in SketchUp before exporting and verify the bounding box in your slicer after import.
Can I convert SKP to STL without SketchUp?
Yes - the converter on this page works without SketchUp, though
.skp is a proprietary format and some files may not convert perfectly.Programs that convert SKP: PolyTrans|CAD+DCC · SketchUp · 3ds Max (3D Studio Max) · Autoconverter · SketchUp for Mac · Online CAD converter · Babel3D
