Automated STL Remeshing?

MauJ · September 10, 2022, 19:41

I'm working on a project that receives numerous STL files as multi-part objects (example attached). I'm having trouble finding a way to automate re-meshing of these objects so that they are optimised for 3D printing (e.g. no internal geometry).

Does anyone have any suggestions for how I can achieve this on a local machine with scripting (which will help with automation)?

I think you need a CAD kernel to do this, as the single entities do not share any points. E.g. in freecad, import the files, create parts (solids) from the files, then perform a boolean operation to add them up and then export the result to stl again. This can all be scripted and freecad runs just fine without gui open.
Hope this helps.
