PLY to STL — turn a 3D scan into a model you can print
Convert a PLY scan to STL: text or binary PLY from a scanner, photogrammetry or MeshLab. Close the holes scans always have, make the file smaller and set the size. In your browser, nothing uploaded.
Saves model files for your slicer, never printer code. Opened and sliced in PrusaSlicer, OrcaSlicer, Bambu Studio and Cura.
About this conversion
Scans come with holes where the scanner could not see, and with far more triangles than a printer needs. Repair closes the holes into one solid, Reduce takes out triangles where the surface is flat or nearly so, and the size is shown in millimetres before saving. A PLY that holds only points — a point cloud — has no surface yet and has to be meshed first, for example in MeshLab.
Just want to look inside it?
The same tool without converting anything: open the file and read it.
The same model, other ways
The model stays open after it is read, so the format is picked at the end: the same model can leave here as 3MF (.3mf), OBJ (.obj) or STEP (.step). Before that you can repair it, cut it, make it smaller or combine it with another one.
Questions
- The scan is tiny or huge
- Many scanners save in metres. Use ×1000 or ÷1000 under Mirror, scale, or Set size for the size you want.
