Voxel to voxel error compared to center of mass for all 6 scaffolds. Scaffolds exhibited noticeably worse print quality on their exterior surface where the 3D printer made abrupt changes in direction when depositing material. Note that for irregular geometries like the zygoma and orbital arch, the exterior boundary was not always the farthest distance from the center of mass. Additionally, scaffolds with more complex external geometries exhibited larger voxel error
