Convert PLY to STL in your browser
Turn an ASCII PLY scan mesh into print-ready ASCII STL without installing anything. The parsing and the facet-normal maths both run in your tab.

Étape par étape
- 1Make sure the PLY is ASCII, not binary (re-save from MeshLab or CloudCompare if needed).
- 2Drop the file above and download the .stl.
- 3Open it in your slicer and check the bounding box against the real object before printing.
- 4If the slicer reports non-manifold edges, repair the mesh — a scan surface is rarely watertight as exported.
Points de vigilance
- Scan colour is lost: STL stores triangles and nothing else.
- Scan meshes are dense. Decimating to the detail you actually need keeps slicing times sane.
- Output is ASCII STL; re-save as binary in the slicer if you need a smaller file.
The Stanford scan format. Plain text in its ASCII flavour, which is why photogrammetry and laser-scan meshes can be rewritten here.
The triangle-soup format every 3D printer and mesh tool reads. Openly documented in both ASCII and binary form, with no units, colours or structure.
Questions fréquentes des dessinateurs
Is the result printable straight away?
Geometrically yes, but scan meshes usually need a hole-filling and manifold pass before a printer will accept them.
Does it handle point clouds?
No. Without faces there are no triangles to write — mesh the cloud first.
