Choose fileWhat is it? Mesh Doctor analyzes a mesh for holes, non-manifold edges, degenerate faces and watertightness, then repairs the defects and lets you export a clean STL.
TL;DR: Find and fix holes, normals and degenerate faces, then export STL.
How to use
- Open a model.
- Review the diagnostics (holes, non-manifold, watertight).
- Run the repair and download the STL.
FAQ
Will it keep my details?
Repairs fill holes and remove degenerates; fine detail is preserved within the mesh resolution.
Is it private?
Yes — analysis and repair are local.
Limitations
- Very large holes may be bridged in a simplified way.
- Dense meshes take longer to process.
