From [this](https://discourse.slicer.org/t/3d-model-of-only-the-outer-surface-of-a-bone-3d-model-of-a-bone/2714/6) thread:  
“Cleaver generates a “background” mesh so that you can simulate embedding your structures in some material (soft tissue, etc). If you don’t need these mesh elements, then don’t use them. Each cell is assigned to a segment, specified by `labels` cell attribute. You can use this attribute to assign material properties or remove parts of the mesh, etc.”
