Title (EN) HEAT SINK SUPPORT STRUCTURES IN ADDITIVE MANUFACTURING
(FR) STRUCTURES DE SUPPORT DE DISSIPATEUR THERMIQUE EN FABRICATION ADDITIVE
Abstract:
(EN) Additive manufacturing methods and corresponding systems and computer-readable mediums. A method includes receiving (505), by a data processing system (600), a three-dimensional (3D) model (100) of a product to be manufactured by additive manufacturing. The method includes generating (510), by the data processing system (600), a time-based heat map (306) of temperatures of the product during manufacture. The method includes identifying (515), by the data processing system (600), hot spots (302) in the heat map (306) where the temperature exceeds a first predetermined threshold. The method includes adding (525), by the data processing system (600), heatsink support structures (422) to the 3D model at locations corresponding to the hot spots (302) to produce a modified 3D model. The method includes storing (530), by the data processing system (600), the modified 3D model (420).
(FR) L'invention concerne des procédés de fabrication additive et des supports lisibles par ordinateur correspondants. Un procédé comprend la réception (505), par un système de traitement de données (600), d'un modèle tridimensionnel (3D) (100) d'un produit à fabriquer par fabrication additive. Le procédé comprend la génération (510), par le système de traitement de données (600), d'une carte thermique temporelle (306) des températures du produit pendant la fabrication. Le procédé comprend l'identification (515), par le système de traitement de données (600), de points chauds (302) dans la carte thermique (306) où la température dépasse un premier seuil prédéterminé. Le procédé comprend l'ajout (525), par le système de traitement de données (600), de structures de support de dissipateur thermique (422) au modèle 3D aux emplacements correspondant aux points chauds (302) pour produire un modèle 3D modifié. Le procédé comprend le stockage (530), par le système de traitement de données (600), du modèle 3D modifié (420).
