Why do AI-generated meshes often fail print checks, and which Toolbox check maps to each failure?
Problem. Text-to-3D meshes often arrive unprintable. Conditions. Marching-cubes-like or fused-surface outputs; Method. Inference only: the failure classes map to named checks: holes and flipped faces = Solid; overlapping shells = Intersections; sliver triangles = Degenerate; paper-thin cloth, hair or fingers = Thickness; floating details = Overhang. Run Check All, then Make Manifold, then re-check and scale. Failure modes. Auto-repair on large openings can invent geometry. Limitations. Reasoning not a measured failure rate; no AI mesh was tested; sources document only the checks, not AI origin. Version and date. Blender 3.6 manual, 2025.
