New WebApp for repairing damaged models
I just published new WebApp that can repair non-manifold, non-watertight or otherwise damaged STL and 3MF files. It runs directly in your browser using WASM, it does not send your files to the server.
It is not yet perfect, it can fill holes, fix non-manifold edges, orient normals, union overlapping shells. But in some complex cases some small number of non-manifold vertices can stay unfixed and the model can have some self-intersections. PrusaSlicer can usually handle these without problem and allow printing of previously unprintable models.
The app can be found at https://jkavalik.github.io/meshseal/ and the code is on github under MIT license.
I tested it on couple hundreds models I gathered in a decade of my 3d printing journey. I would be glad if you test it and if you find it useful, and for any feedback you could offer.
The webapp is based on a library of the same name which I am offering for slicer integration instead or next to the windows-based model fix - it is generally faster and does not change the original geometry as much and - what I consider most important - it works on Linux (tested) and MacOs (not directly tested by me yet in the slicer, only the library itself) too, bringing the functionality that was previously missing. The win repair can still fix the most broken models a bit better by doing more agressive changes to the geometry.
Disclaimer: I designed the repair library and this app, but the code was written by AI, because I would not be able to do it manualy in any reasonable time. Even using AI to code it took a couple of months and 4 rewrites over 3 programming languages.
