Is there an existing issue for this feature request?

I have searched the existing issues

There are a number of mesh Boolean related issues in orca-slicer and bambu studio, e.g., #7603, #9028, #10899. Some are no longer open not because they are fixed, but because they are stale.

Which printers will be beneficial to this feature?

All

Describe the solution you'd like

There is a new mesh Boolean library called manifold that is both efficient and robust. It is currently used by libraries such as blender, brlcad, openscad. It does not require adding extra dependencies except itself.

It only accepts manifold meshes, so inputs may have to be repaired.
