About These Formats
Polygon File Format
PLY is a flexible format for storing 3D polygon meshes. It supports vertex colors, custom properties, and is commonly used for 3D scan data and point clouds.
Used with
3D scanning, photogrammetry, research, point cloud processing (MeshLab, CloudCompare).
Stereolithography
STL stores only triangulated geometry — no colors, textures, or animations. It is the de-facto standard for 3D printing slicers and CAD software.
Used with
3D printing slicers (Cura, PrusaSlicer, Bambu Studio), CAD tools, rapid prototyping workflows.
When to Convert PLY to STL
Convert PLY to STL when you need to 3D print the model. STL is the universal format for slicing software like Cura, PrusaSlicer, and Bambu Studio. Note that STL contains geometry only — colors and textures from the PLY source will not be included.
