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 system and method for authenticating an additively manufactured component are provided. The method includes locating an identifying region on the component which may be positioned at a predetermined location relative to an identifiable datum feature. The identifying region may be scanned to determine a component identifier of the component. A reference identifier may be obtained from a database and compared to the component identifier to determine whether the component is authentic.

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 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: 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 ceramic resin is provided, along with its methods of formation and use. The ceramic resin may include a crosslinkable precursor, a photoinitiator, ceramic particles, and pore forming particles. The ceramic resin may be utilized to form a ceramic casting element, such as via a method that includes forming a layer of the ceramic resin; applying light onto the ceramic resin such that the photoinitiator initiates polymerization of the crosslinkable precursor to form a crosslinked polymeric matrix setting the ceramic particles and the pore forming particles; and thereafter, heating the crosslinked polymeric matrix to a first temperature to burn out the pore forming particles.

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.
