About this website
STLRepair is an online STL repair tool for makers and 3D printing users. Upload a binary or ASCII STL to preview the model and check open boundaries, non-manifold edges, and invalid triangles. Apply supported basic repairs locally in your browser and download the result without an account. For eligible complex issues, optional cloud-based advanced repair provides a quality report, with a $3.99 one-time payment for an accepted result. Pro adds automated batches of up to five STL files.
Key features
- Free STL mesh diagnostics in the browser
- Supported basic repairs and STL downloads without signup
- Binary and ASCII STL file support
- Interactive 3D model preview
- Checks for open boundaries, non-manifold edges, and invalid triangles
Who is this website for?
3D printing hobbyists, makers and DIY creators, users of Bambu Studio, Cura, and PrusaSlicer, and small 3D printing studios.
What can visitors do here?
Fix a slicer non-manifold or open-edges warning before printing, or clean up a downloaded or 3D-scan STL in the browser without installing a modeling app.
What makes it different?
STLRepair starts with free, local mesh checking and supported basic fixes instead of making cloud processing the default. Users can see detected issues, review the repair outcome, and decide whether a harder case needs advanced processing.
