Good to know
Scans often come in meters, and the vertex colors are dropped. Scans are rarely watertight, so run the STL repair tool after converting.

About PLY
PLY (Polygon File Format). The Stanford scan format. 3D scanners and photogrammetry apps export it, often with a color per vertex.
Units: None in the file. Scanners usually write meters or millimeters. Up axis: Z. Opens in MeshLab, Blender, and CloudCompare.
About STL
STL (Stereolithography). The default 3D printing format since 1987: a bare list of triangles. Every slicer reads it, but it has no units, no color, and no parts.
Units: None in the file. Slicers read the numbers as millimeters. Up axis: Z. Opens in Bambu Studio, PrusaSlicer, Cura, OrcaSlicer, and Blender.

- Will the STL keep colors and materials?
- No. STL has no place for colors, so only the shape carries over.
- What units is the STL in?
- PLY: None in the file. Scanners usually write meters or millimeters. STL: None in the file. Slicers read the numbers as millimeters. The converter does not guess. Use the scale option if the size looks wrong.
- How do I open an STL file?
- Bambu Studio, PrusaSlicer, Cura, OrcaSlicer, and Blender all open STL.
