Non-manifold geometry startles 3D printers as much as anyone else who tries to wrap his head around the idea for the first time. Typically this conundrum results from extruding but not moving faces and edges. Simply put, non-manifold geometries are identical edges directly on top of each other. STL Repair Tip #2: Check for non-manifold geometry All of our STL repair tools listed below can handle these 3D mesh problems easily. A 3D printer faced with such a file can’t tell an outer surface from an inner surface. One of the most common errors encountered when 3D printing are STL files that have holes in their meshes – they are not “watertight”. Here are the most common design mistakes – and what you should repair so your 3D model prints correctly. STL Repair Tips: Checklist for 3D DesignerĪ 3D model isn’t automatically a 3D printable file.
