Convert PLY to STL
Turn a PLY surface mesh from a scanner or photogrammetry pipeline into an STL. The tool keeps the triangles and drops per-vertex colours, which STL cannot store.

What changes in the conversion
Dropped
- Vertex colours
- Normals are recomputed for display
- Point-cloud-only PLY files are rejected
Common mistakes
- A PLY containing only points (no faces) cannot be converted to a surface.
- Scans often contain holes and noise; the STL will keep them.
- Large photogrammetry meshes may need to be split below 100 MB.
For 3D printing
- Scans are rarely watertight: repair holes before slicing.
- Check the scale: photogrammetry often outputs arbitrary units.

Frequently asked questions
Does it support PLY point clouds?+
No. Only polygon meshes with faces are converted. A point cloud has no surface to export as STL.
Are the vertex colours kept?+
No. STL has no colour support. Export an OBJ or GLB if colours matter.
My scan is huge, will it work?+
The limit is 100 MB per file. For larger scans, decimate or split the mesh in your scanning software first.
Need a model instead of a conversion?
Turn a photo, a drawing or a logo into a 3D model, then export it in the format you need.
