Title (EN) SYSTEMS AND METHODS FOR MEASURING RADIATED THERMAL ENERGY DURING AN ADDITIVE MANUFACTURING OPERATION
(FR) SYSTÈMES ET PROCÉDÉS DE MESURE D'ÉNERGIE THERMIQUE RAYONNANT PENDANT UNE OPÉRATION DE FABRICATION ADDITIVE
Abstract:
(EN) This disclosure describes various methods and apparatus for characterizing an additive manufacturing process. A method for characterizing the additive manufacturing process can include generating scans of an energy source across a build plane; measuring an amount of energy radiated from the build plane during each of the scans using an optical sensor; determining an area of the build plane traversed during the scans; determining a thermal energy density for the area of the build plane traversed by the scans based upon the amount of energy radiated and the area of the build plane traversed by the scans; mapping the thermal energy density to one or more location of the build plane; determining that the thermal energy density is characterized by a density outside a range of density values; and thereafter, adjusting subsequent scans of the energy source across or proximate the one or more locations of the build plane.
(FR) La présente invention concerne divers procédés et appareil pour caractériser un processus de fabrication additive. Un procédé pour caractériser le processus de fabrication additive peut consister à générer des balayages d'une source d'énergie à travers un plan de construction ; à mesurer une quantité d'énergie rayonnant à partir du plan de construction pendant chacun des balayages à l'aide d'un capteur optique ; à déterminer une zone du plan de construction traversée pendant les balayages ; à déterminer une densité d'énergie thermique pour la zone du plan de construction traversée par les balayages sur la base de la quantité d'énergie rayonnant et de la zone du plan de construction traversée par les balayages ; à mapper la densité d'énergie thermique sur un ou plusieurs emplacements du plan de construction ; à déterminer que la densité d'énergie thermique est caractérisée par une densité à l'extérieur d'une plage de valeurs de densité ; puis à ajuster des balayages ultérieurs de la source d'énergie à travers ou à proximité du ou des emplacements du plan de construction.
