Title
(EN) PROCESSING A 3D OBJECT MESH MODEL IN A 3D PRINTER
(FR) TRAITEMENT D'UN MODÈLE MAILLÉ D'OBJET 3D DANS UNE IMPRIMANTE 3D
Abstract
(EN)
In a method for processing a 3D object mesh model a 3D printer receives a 3D object mesh model of a 3D object to be printed. The 3D printer determines whether the received 3D object mesh model violates a manifold requirement. It further provides an auto-repair option for the violating 3D object mesh model which has been determined to violate the manifold requirement. The auto-repair option is to repair the violating 3D object mesh model such that the repaired 3D object mesh model meets the manifold requirement.
(FR)
Dans un procédé de traitement d'un modèle maillé d'objet 3D, une imprimante 3D reçoit un modèle maillé d'objet 3D d'un objet 3D à imprimer. L'imprimante 3D détermine si le modèle maillé d'objet 3D reçu n'est pas conforme aux exigences du collecteur. Elle fournit en outre une option d'auto-réparation pour le modèle maillé d'objet 3D non conforme qui a été déterminé non conforme aux exigences du collecteur. L'option d'auto-réparation consiste à réparer le modèle maillé d'objet 3D non conforme de sorte que le modèle maillé d'objet 3D réparé réponde aux exigences du collecteur.
