Title
(EN) BEAM LATTICE DATA IN ADDITIVE MANUFACTURING
(FR) DONNÉES DE RÉSEAU DE FAISCEAU DANS LA FABRICATION ADDITIVE
Abstract
(EN) In an example a method includes receiving, at processing circuitry, beam lattice data modelling at least part of a three-dimensional object to be generated using additive manufacturing as a beam lattice. A volumetric data model may be determined from the beam lattice data. Determining the volumetric data model may comprise dividing a volume containing the beam lattice data into sub-volumes and categorising the sub- volumes into (I) interior sub-volumes, which are wholly within a beam of the beam lattice; (ii) exterior sub-volumes which are wholly outside the beams of the beam lattice; and (ii) boundary sub-volumes which partially coincide with a beam of the beam lattice. The method may further comprise subdividing boundary sub-volumes and categorising the subdivided sub-volumes until a threshold volume size of boundary sub-volume is reached.
(FR) Dans un exemple, un procédé consiste à recevoir, au niveau de circuits de traitement, des données de réseau de faisceau modélisant au moins une partie d'un objet tridimensionnel à générer par fabrication additive en tant que réseau de faisceau. Un modèle de données volumétriques peut être déterminé à partir des données de réseau de faisceau. La détermination du modèle de données volumétriques peut comprendre la division d'un volume contenant les données de réseau de faisceau en sous-volumes et la catégorisation des sous-volumes en (i) des sous-volumes intérieurs, qui sont entièrement à l'intérieur d'un faisceau du réseau de faisceaux ; (ii) des sous-volumes extérieurs qui sont entièrement à l'extérieur des faisceaux du réseau de faisceaux ; et (iii) des sous-volumes limites qui coïncident partiellement avec un faisceau du réseau de faisceaux. Le procédé peut en outre consister à subdiviser des sous-volumes limites et à catégoriser les sous-volumes subdivisés jusqu'à ce qu'une taille de volume seuil du sous-volume limite soit atteinte.
