Title
(EN) SYSTEM FOR RAPID OBJECT PRODUCTION USING FLOW INFILL DESIGN
(FR) SYSTÈME POUR LA PRODUCTION RAPIDE D'OBJETS À L'AIDE D'UNE CONCEPTION DE REMPLISSAGE PAR ÉCOULEMENT
Abstract
(EN) A computer system for part production using flow infill design receives a computer-aided design file that describes physical dimensions of a target object (120). The computer system identifies a physical boundary portion (300) of the target object within the CAD file. The computer system generates a first tool path to additively manufacture the physical boundary portion (300). Additionally, the computer system sends instructions to a computer system in communication with a dispenser (130) that cause the dispenser to implement the first tool path while dispensing a boundary material. Further, the computer system generates a command to dispense the coreactive infill material (310) within the physical boundary portion.
(FR) La présente invention concerne un système informatique pour la production de pièces faisant appel à une conception de remplissage par écoulement qui reçoit un fichier de conception assistée par ordinateur (CAO) qui décrit les dimensions physiques d'un objet cible (120). Le système informatique identifie une partie limite physique (300) de l'objet cible au sein du fichier de CAO. Le système informatique génère un premier trajet d'outil pour fabriquer de manière additive la partie limite physique (300). De plus, le système informatique envoie des instructions à un système informatique en communication avec un distributeur (130) qui amènent le distributeur à mettre en œuvre le premier trajet d'outil tout en distribuant un matériau de limite. En outre, le système informatique génère une commande pour distribuer le matériau de remplissage coréactif (310) à l'intérieur de la partie limite physique.
