Systems and methods for measuring radiated thermal energy during an additive manufacturing operation
Patent number: 11938560Abstract: 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.Type: GrantFiled: June 14, 2022Date of Patent: March 26, 2024Assignee: DIVERGENT TECHNOLOGIES, INC.Inventors: R. Bruce Madigan, Lars Jacquemetton, Glenn Wikle, Mark J. Cola, Vivek R. Dave, Darren Beckett, Alberto M. Castro -
Publication number: 20240085336Abstract: This disclosure describes various system and methods for monitoring photons emitted by a heat source of an additive manufacturing device. Sensor data recorded while monitoring the photons can be used to predict metallurgical, mechanical and geometrical properties of a part produced during an additive manufacturing operation. In some embodiments, a test pattern can be used to calibrate an additive manufacturing device.Type: ApplicationFiled: April 19, 2023Publication date: March 14, 2024Applicant: Sigma Additive Solutions, Inc.Inventors: Vivek R.
