Réparation et optimisation de maillages 3D pour l'impression 3D

Abstract : 3D printers use 3D models in the form of meshes to define the geometry and the appearance of objects to be printed. A 3D mesh must have some topological properties so that the geometry it represents could be printable and the geometry itself must respect certain conditions to be printable. These properties and conditions may vary depending on the 3D printing technologies in use.Many 3D meshes used for printing were not initially designed for this purpose application. The main primary use of these meshes is visualization, which does not require the same topological properties and geometric conditions. The subject of this thesis is the repair of these meshes to make them printable.A repair chain including several steps was designed for this purpose. Non-manifold conditions are repaired by extracting related components (surfaces). The boundaries of surfaces are detected and classified according to the best repair to be applied on each. The boundaries of surfaces are repaired according to their classification either by a filling method or by an offset method. The weakness of the geometry is detected and controlled.
