Hi everyone,

Is there an available library or function to repair a .stl file within MATLAB (or call an external tool from Matlab)?

There is this website that does exactly what I need to do ( https://www.formware.co/onlinestlrepair ) in terms of repair but I would need to automate the process from within the Matlab environment. Unfortunately meshlab does not seem to be linkable with Matlab anymore. When I say cleaning/repairing a .stl I primaraly (but not limited to) mean: naked edges, planar holes, non-planar holes, non-manifold edges, inverted faces, degenerate faces, duplicate faces, disjoint shells.

If no libraries/functions are available, would you have any advice on how to create a script that could tackle the problem?

Many thanks

Hey Claud,

In MATLAB, there isn't a built-in function or library specifically designed to repair .stl files. However, you can use external tools or libraries by calling them from MATLAB to repair .stl files. As meshlab was not working here is another alternative.

Python libraries: MATLAB supports calling Python functions and libraries using the Python integration feature. You can use Python libraries such as `trimesh` or `pyvista` to repair .stl files. Write a Python script that performs the repair operation and call it from MATLAB using the `py` function.

output = py.python_script.repair_stl('input.stl');
