    Abstract: A scanning technique for the additive manufacturing of an object. The method comprises the irradiation of a portion of a given layer of powder to form a fused region using an energy source. When forming an object layer by layer, the irradiation follows a first irradiation path bounded by a first stripe, wherein the first irradiation path is formed at an oblique angle with respect to the first stripe. The first irradiation path further comprises at least a first scan vector and a second scan vector at least partially melting a powder and forming a first solidification line and second solidification line respectively, wherein the first solidification intersects and forms an oblique angle with respect to the second solidification line. After a layer is completed, a subsequent layer of powder is provided over the completed layer, and the subsequent layer of powder is irradiated. Irradiation of the subsequent layer of powder follows a second irradiation path bounded by a second stripe. wherein the second irradiation path is formed at an oblique angle with respect to the second stripe. The first irradiation path further comprises at least a third scan vector and a fourth scan vector at least partially melting a powder and forming a third solidification line and fourth solidification line respectively, wherein the third solidification intersects and forms an oblique angle with respect to the fourth solidification line

    Abstract: 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.

    Abstract: A system and method for manufacturing and authenticating a component is provided. The method includes forming a component having an identifying region that contains two or more materials having different conductivities such that the identifying region generates an eddy current response signature that defines a component identifier of the component. The method further includes interrogating the identifying region of the surface with an eddy current probe to determine the component identifier. The component identifier may be stored in a database as a reference identifier and may be used for authenticating components.

    Abstract: An additive manufacturing machine includes an energy beam system configured to emit an energy beam utilized in an additive manufacturing process, and one or more optical elements utilized by, or defining a portion of, the energy beam system and/or an imaging system of the additive manufacturing machine. The imaging system monitors one or more operating parameters of the additive manufacturing process. A light source is configured to emit an assessment beam that follows an optical path incident upon the one or more optical elements. One or more light sensors detect a reflected beam comprising at least a portion of the assessment beam at a perimeter edge of the one or more optical elements. A control system determines, based at least in part on assessment data comprising data from the one or more light sensors, whether at least one of the one or more optical elements exhibits an optical anomaly.
    A light source is configured to emit an assessment beam that follows an optical path incident upon the first and second optical elements. One or more light sensors detect a reflected beam that is either internally reflected by the first optical element or reflectively propagated between the first and second optical elements. A control system determines, based at least in part on assessment data comprising data from the one or more light sensors, whether at least one of the first and second optical elements exhibits an optical anomaly.
