Patent number: 11938539Abstract: A build unit for additively manufacturing three-dimensional objects may include an energy beam system having one or more irradiation devices respectively configured to direct one or more energy beams onto a region of a powder bed, and an inertization system including an irradiation chamber defining an irradiation plenum, one or more supply manifolds, and a return manifold. The one or more supply manifolds may include a downflow manifold configured to provide a downward flow of a process gas through at least a portion of the irradiation plenum defined by the irradiation chamber, and/or a crossflow manifold configured to provide a lateral flow of the process gas through at least a portion of the irradiation plenum defined by the irradiation chamber. The return manifold may evacuate or otherwise remove process gas from the irradiation plenum defined by the irradiation chamber.Type: GrantFiled: April 16, 2021Date of Patent: March 26, 2024Assignees: General Electric Company, Concept Laser GmbHInventors: Eric Edward Halla, Ramakrishna Venkata Mallina, Kishore Ramakrishnan, Shashwat Swami Jaiswal, Mohammed Mounir Shalaby, Peter Pontiller-Schymura

Patent number: 11065815Abstract: A powder dispensing assembly for an additive manufacturing machine includes a hopper defining a powder reservoir for receiving additive powder and a plurality of powder distribution modules operably coupled with the hopper. The powder distribution modules include a powder distribution body defining a discharge orifice and a supply gate that fluidly couples the powder reservoir to the discharge orifice. A plunger valve is movably mounted over the discharge orifice and an actuator moves the plunger valve between an open position and a closed position to selectively dispense a flow of additive powder.Type: GrantFiled: December 18, 2018Date of Patent: July 20, 2021Assignee: General Electric CompanyInventors: Ryan William Van Deest, Eric Edward Halla

Publication number: 20210016394Abstract: A method of aligning at least one laser beam of an additive manufacturing arrangement. The method includes measuring a surface of the calibration plate at a plurality of measurement points using the coordinate measuring machine. The method further includes generating a correction field based on the plurality of measurement points using the coordinate measuring machine. The method further includes writing at least one fiducial mark on the surface of the calibration plate using the at least one laser beam. The method further includes generating calibration data for the surface of the calibration plate using the calibration system. The method also includes aligning the laser beam within the additive manufacturing system based on the calibration data and the correction field using the computing device by comparing a position of the fiducial mark from the calibration data with the correction field to determine a corrected position of the laser beam.Type: ApplicationFiled: July 18, 2019Publication date: January 21, 2021Inventors: Brian Scott McCarthy, Eric Edward Halla, Thomas Charles Adcock, Michael Evans Graham, Andrea Marie Schmitz, Mark Samuel Bailey
