The Stereolithography (STL) format stores surface geometry as triangulated mesh data. It is the universal standard for 3D printing but lacks support for colors, textures, and materials.
PLY (Polygon File Format) stores 3D data from 3D scanners and photogrammetry software. It can include vertex colors, normals, and custom properties, making it popular in scientific computing and 3D scanning.
Converting STL to PLY enables compatibility with 3D scanning, photogrammetry, and scientific visualization. Upload your Stereolithography file and get a Polygon File Format file ready for download in seconds.
