    Abstract: An additively manufactured component and a method for manufacturing the same are provided. The additively manufactured component includes a cross sectional layer having a surface surrounding the cross sectional layer. The cross sectional layer is formed by moving a focal point of an energy source over a bed of additive material. A surface irregularity is formed on the surface by manipulating the energy level of the energy source. The surface may include a datum feature positioned at a predetermined location relative to the surface irregularity and the surface irregularity may be greater than a surface roughness of the surface but less than one millimeter.

    Abstract: Devices, systems, methods, and kits of parts for monitoring operation of an electron beam additive manufacturing systems are disclosed. A monitoring system includes one or more measuring devices positioned on the at least one wall in the interior of a build chamber of the additive manufacturing system. Each one of the one or more measuring devices includes a piezoelectric crystal. The monitoring system further includes an analysis component communicatively coupled to the one or more measuring devices. The analysis component is programmed to receive information pertaining to a frequency of oscillation of the piezoelectric crystal. A collection of material on the one or more measuring devices during formation of an article within the build chamber causes a change to the frequency of oscillation of the piezoelectric crystal that is detectable by the analysis component and usable to determine a potential build anomaly of the article.

    Abstract: A method of calibrating a beam scan field of an additive manufacturing machine in which a radiant energy beam is used to selectively melt material to form a workpiece, the method including: using a radiant energy source, directing a beam using a steering mechanism so as to create a calibration build job on a substrate, the calibration build job including at least one measurement artifact created by the beam; using a calibrated camera, collecting an image of the calibration build job; generating a set of measurements of the calibration build job from the image; comparing the measurements to a standard; in response to the measurements deviating from the standard by more than a predetermined acceptable tolerance, adjusting the steering mechanism; wherein the steps of directing, collecting, generating, comparing, and adjusting are carried out in response to automated commands from an electronic controller.

    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 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.
