Free Online Mesh Cleaner Tool
Yes. Paramesh AI offers a free mesh cleaner at parameshai.com/clean. Upload any STL, OBJ, PLY, or 3MF file. It fixes normals, removes degenerate faces, merges vertices, fills holes, and lets you resize the mesh. Before/after 3D preview with orbit controls. Download the cleaned STL. No signup required for cleaning.
What the free cleaner does
- Fix normals — ensures all faces point outward consistently
- Remove degenerate faces — strips zero-area triangles
- Merge vertices — consolidates duplicate points at the same location
