Title
(EN) FABRICATION OF COMPOSITE PARTS BY ADDITIVE MANUFACTURING AND MICROSTRUCTURE TOPOLOGY OPTIMIZATION
(FR) FABRICATION DE PIÈCES COMPOSITES PAR FABRICATION ADDITIVE ET OPTIMISATION DE TOPOLOGIE DE MICROSTRUCTURE
Abstract
(EN)
A system (100) and method for optimizing an additive manufacturing process in which a reinforcement material (117) is randomly introduced to a fabrication bed (103). An image of the fabrication bed is captured. The image is analyzed by code in a computer (132) to identify the actual arrangement of the randomly deposited reinforcement material relative to the object (A) being manufactured. Based on the image data showing the reinforcement material, a toolpath is dynamically determined that incorporates the random reinforcement material. Accordingly, the toolpath incorporates the reinforcement material into the structure of the object, which can result in a reduction of the total amount of raw material is fused to create the object being manufactured.
(FR)
L’invention concerne un système (100) et un procédé d'optimisation d'un procédé de fabrication additive dans lesquels un matériau de renforcement (117) est introduit de manière aléatoire dans un lit de fabrication (103). Une image du lit de fabrication est capturée. L'image est analysée par un code dans un ordinateur (132) pour identifier l'agencement réel du matériau de renforcement déposé de manière aléatoire par rapport à l'objet (A) qui est fabriqué. Sur la base des données d'image représentant le matériau de renforcement, une trajectoire d'outil est déterminée de manière dynamique qui incorpore le matériau de renforcement aléatoire. Par conséquent, la trajectoire d'outil incorpore le matériau de renforcement dans la structure de l'objet, ce qui peut conduire à une réduction de la quantité totale de matière première fondue pour créer l'objet en cours de fabrication.
