Operation

manifold kernel requires oriented manifold input (auto-welded from triangle soup); BVH fallback accepts looser geometry.

What is it? Mesh Boolean performs union, subtract and intersect operations between two meshes (STL/OBJ/PLY/3MF/GLB) and exports the result as STL, all locally in the browser.

TL;DR: Union/subtract/intersect two meshes and export STL.

How to use

Load mesh A and mesh B.
Choose the boolean operation.
Preview and download the STL.

FAQ

Do the meshes need to be watertight?

Yes — clean, watertight inputs give the most reliable results; repair first with Mesh Doctor.

Is it local?

Yes, the boolean runs in your browser.

Limitations

Non-manifold or self-intersecting inputs may fail.
Computationally heavy for dense meshes.
