Abstract: Systems and methods for optical based monitoring of additive manufacturing processes are provided. In one example a method includes obtaining optical data representing a layer of a structure being manufactured using an additive manufacturing process, comparing the optical data with a standard optical representation associated with the structure, determining one or more nonconformance conditions between the optical data representing the layer and the standard optical representation, and implementing a control action based at least in part on the one or more nonconformance conditions.

Abstract: A system and method of monitoring a powder-bed additive manufacturing process is provided where a layer of additive powder is fused using an energy source and electromagnetic emission signals are measured by a melt pool monitoring system to monitor the print process. The measured emission signals are analyzed to identify outlier emissions and clusters of outliers are identified by assessing the spatial proximity of the outlier emissions, e.g., using clustering algorithms, spatial control charts, etc. An alert may be provided or a process adjustment may be made when a cluster is identified or when a magnitude of a cluster exceeds a predetermined cluster threshold.

Abstract: A calibration system for an acoustic monitoring system of an additive manufacturing machine includes a calibration platform removably mountable to a build platform of the additive manufacturing machine and one or more calibrated acoustic sources mounted to the calibration platform. The one or more calibrated acoustic sources define a measurement standard when operating.

Abstract: A system and method for additively manufacturing a component including features for part identification are provided. The method includes selectively depositing a contrast agent on a cross sectional layer to define a component identifier of the component and directing energy from an energy source onto the contrast agent to fuse the contrast agent and the cross sectional layer. The contrast agent may be an x-ray emission contrast agent that is read using an x-ray emission spectroscopy method, an infrared contrast agent that is read using an infrared camera or an infrared scanner, or a radioactive contrast agent that is read using a gamma ray spectrometer.

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: The present disclosure generally relates to methods for additive manufacturing (AM) that utilize thermal dissipation support structures in the process of building objects, as well as novel thermal dissipation support structures to be used within these AM processes. The thermal dissipation support structures include at least one sacrificial structure that is separated from the object by a portion of unfused powder. The sacrificial structure increases a thermal dissipation rate of at least a portion of the object such that such that thermal gradients in the object remain below a specified threshold that prevents deformation of the object.

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.
