Title (EN) PARALLELIZED CAD USING MULTI LASER ADDITIVE PRINTING
(FR) CAO PARALLÉLISÉE UTILISANT UNE IMPRESSION ADDITIVE À LASERS MULTIPLES
Abstract:
(EN) The present disclosure generally relates to additive manufacturing or printing of an object using parallel processing of files comprising 3D models of the object and/or portions thereof. A master file comprising a 3D model of the object is divided into subordinate files, wherein each subordinate file comprises a 3D model of a corresponding portion of the object. Each subordinate file is processed in parallel, controlling at least a first laser source to fabricate each portion from a build material. Parallel processing according to the methods of the present disclosure expedites additive manufacturing or printing over conventional methods that build an object in layers completed in series.
(FR) La présente invention concerne de manière générale la fabrication ou l'impression additive d'un objet en utilisant un traitement parallèle de fichiers contenant des modèles en 3D de l'objet et/ou de ses parties. Un fichier maître contenant un modèle en 3D de l'objet est divisé en fichiers subordonnés, chaque fichier subordonné contenant un modèle en 3D d'une partie correspondante de l'objet. Chaque fichier subordonné est traité en parallèle. Il commande au moins une première source laser de manière à fabriquer chaque partie en un matériau de construction. Un traitement parallèle d'après les procédés de la présente invention accélère la fabrication ou l'impression additive par rapport à des procédés classiques qui construisent un objet en couches réalisées en série.
