Abstract: A system and method for calibrating a melt pool monitoring system of an additive manufacturing machine includes installing a calibration system on the machine and performing a calibration process. Specifically, the calibration system includes a calibration platform removably mountable to a build platform of the additive manufacturing machine and having calibrated electromagnetic energy sources mounted thereon for defining a measurement standard. The electromagnetic energy generated is measured by the melt pool monitoring system and compared to the known measurement standard to determine whether system adjustments would improve process tolerances or uniformity.

Abstract: A method of characterizing gas flow within a housing includes: positioning one or more gas flow sensors in the housing; introducing a gas flow into the housing; using the one or more gas flow sensors to generate two or more gas flow measurements at spaced-apart locations within the housing; and recording the two or more measurements to create a gas flow map.

Abstract: A component incorporating a 3-D identification code includes: a component body having an interior bounded by an exterior surface; and an identification code formed as a part of at least one of the interior and the exterior surface, the identification code including a plurality of cells arranged in a three-dimensional space, wherein each of the cells is configured to encode more than two possible values.

Abstract: A system and method for manufacturing and authenticating an additively manufactured component are provided. The method includes forming a surface around a cross sectional layer and introducing localized surface variations to the surface. The localized surface variations are configured for generating a unique acoustic wave response that defines a component identifier of the component. The method further includes exciting the surface of the component at an excitation region using an excitation source and interrogating the surface at an excitation region of the component at an interrogation region using a vibration sensor. The acoustic wave response may be compared to a stored component identifier in a database for authenticating components.

Abstract: A system and method for authenticating an additively manufactured component is provided. The method includes locating an identifying region of the component that includes localized density variations that define a component identifier. The method further includes interrogating the identifying region of the component using a scanning device such as an x-ray computed tomography device to obtain the component identifier. The method further includes obtaining a reference identifier from a database, comparing the component identifier to the reference identifier, and determining that the component is authentic if the component identifier matches the reference identifier.

Abstract: A method for additively manufacturing a component is provided. The method includes additively manufacturing an identifying region of the component including localized density variations that define a component identifier of the component. The localized density variations may be formed using two materials having different densities, by manipulating an energy source to underexpose or overexpose a layer of powder, or by laser shock peening the component during the additive manufacturing process. This method generates a three-dimensional unique component identifier that may be invisible to the naked eye and detectable only through interrogation by a scanning device, such as an x-ray computed tomography device. The component identifier may be stored in a database as a reference identifier and may be used for authenticating components.

Abstract: A method for inspecting an additive manufacturing process in which a directed energy source is used to create a weld pool at an exposed build surface of a mass of powdered material, and selectively fuse the powdered material to form a workpiece. The inspection method includes: using a noncontact method to generate an acoustic wave in the build surface; using a noncontact method to measure displacement of the build surface in response to the acoustic wave; and determining at least one sub-surface material property of the workpiece by analyzing the displacement of the build surface.
