摘要： 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.

摘要： 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.

摘要： The present disclosure generally relates to methods for additive manufacturing (AM) that utilize support leading edge structures in the process of building objects, as well as novel leading edge support structures to be used within these AM processes. The support structure is positioned adjacent the object between the object and a first side of the powder bed. The support structure has a shape that tapers outward in the direction from the first side to the object
