What Is AI 3D Model Repair?
AI 3D model repair refers to intelligent algorithms and automation that detect, analyze, and fix complex mesh issues with minimal human intervention. It is not always deep learning; rather, it encompasses advanced computational methods designed to make meshes watertight and manifold, resolve flipped normals, close holes, remove self-intersections, and ensure printability and simulation stability. These tools are essential for preparing assets for 3D printing, manufacturing, AR/VR, games, and industrial design workflows.
