Patent number: 11801633Abstract: The present disclosure generally relates to additive manufacturing systems and methods involving a mechanism for feeding in a desired amount of fresh recoater blade. This can be accomplished by, for example, spooling the fresh blade material from a spool. This helps prevent work stoppage when a portion of a recoater blade becomes damaged. As such, the present disclosure also relates to a system and method for detecting whether a recoater blade is damaged, and if there is damage, then causing a fresh blade portion to be fed in.Type: GrantFiled: October 11, 2021Date of Patent: October 31, 2023Assignee: General Electric CompanyInventors: Todd Jay Rockstroh, Zachary David Fieldman, Theodore Anderson

Patent number: 11370031Abstract: The present disclosure generally relates to additive manufacturing systems and methods on a large-scale format. One aspect involves a build unit that can be moved around in three dimensions by a positioning system, building separate portions of a large object. The build unit has an energy directing device that directs, e.g., laser or e-beam irradiation onto a powder layer. In the case of laser irradiation, the build volume may have a gasflow device that provides laminar gas flow to a laminar flow zone above the layer of powder. This allows for efficient removal of the smoke, condensates, and other impurities produced by irradiating the powder (the “gas plume”) without excessively disturbing the powder layer. The build unit may also have a recoater that allows it to selectively deposit particular quantities of powder in specific locations over a work surface to build large, high quality, high precision objects.Type: GrantFiled: October 16, 2020Date of Patent: June 28, 2022Assignee: General Electric CompanyInventors: MacKenzie Ryan Redding, Zachary David Fieldman, Justin Mamrak
