PLY captures physical objects. STL makes them printable. Convert scans to physical replicas with any 3D printer.
The complete scan-to-print pipeline: capture a real object with a 3D scanner, convert PLY to STL, slice, and print an exact replica.
Our converter produces manifold, watertight STL with correct face normals. Scan meshes are repaired and sealed for successful 3D printing.
Scan existing parts, convert PLY to STL, and 3D print replacements. Ideal for vintage parts, custom fittings, and reverse engineering workflows.
Output is compatible with Cura, PrusaSlicer, Bambu Studio, Simplify3D, Lychee, Chitubox, and every FDM, SLA, and SLS slicing software.
PLY is the standard output of 3D scanners and photogrammetry software. It stores dense point clouds, meshes with vertex colors, and per-vertex properties. STL is the universal 3D printing format. A simple triangle mesh that every slicer can process. Converting PLY to STL is the essential bridge between capturing reality and fabricating physical objects: scan, convert, slice, print.
Mesh geometry (vertices and faces) is fully preserved in the STL output with consistent face normals. Point cloud data (vertices without faces) is tessellated into a triangle mesh using surface reconstruction. Vertex colors, normals, and other PLY per-vertex properties are not preserved. STL is a geometry-only format storing only triangle coordinates and face normals. The output is a monochrome, watertight mesh ready for slicing.
The STL file imports directly into Cura, PrusaSlicer, Bambu Studio, Simplify3D, Lychee Slicer, Chitubox, or any 3D printing slicer. Scale your model in the slicer, select material and print settings, slice, and print. For large scan files, consider decimating the mesh before conversion using MeshLab or our Mesh Decimator tool.
Three steps to transform your 3D scan PLY data into 3D-printable STL files.
Drag and drop your .ply file from a 3D scanner or photogrammetry software. Both point cloud and mesh PLY files are accepted. Free tier: up to 50MB.
Our cloud engine tessellates point clouds, reconstructs surfaces, and writes watertight binary STL with correct face normals for reliable printing.
Download your STL and import into Cura, PrusaSlicer, or Bambu Studio. Scale, slice, and print. Files auto-delete within 1 hour.
