Abstract: A system (100) and method for monitoring a recoating mechanism (415A, 415B) in an additive manufacturing environment is provided. Various embodiments involve the use of a control computer (102a-102d) to receive data based on a thermal image of a recoating mechanism (415A, 415B) from an imaging device (436) configured to capture thermal image. The control computer (102a-102d) further determines a value of a property of the thermal image, wherein the property is related to an amount of powder in the recoating mechanism. The control computer (102a-102d) further determines at least one of if the value indicates an error related to the amount of powder in the recoating mechanism (415A, 415B), and an action to take with respect to the recoating mechanism (415A, 415B) that is based on the value.

Abstract: Systems and methods for generating an energy density map of an object to be built in an additive manufacturing environment are provided. Certain embodiments provide a method for building an object utilizing additive manufacturing, the method including: receiving a job file for building the object, wherein the job file includes a plurality of slices of the object, and wherein a first slice of the object indicates scanning lines for applying an energy source to build material to build the first slice of the object; determining operation parameters of the energy source; and generating a first energy density map of the first slice of the object based on the job file and the operation parameters of the energy source, wherein the first energy density map indicates an amount of energy from the energy source per area of build material applied to the build material for the first slice of the object.

Abstract: Embodiments set forth in this application relate to systems and methods by which parts produced by additive manufacturing can be reliably assessed for conformity to a known master model which has quality conforming to the desired specifications. These systems and methods involve recording a thermal history of the manufacturing process of each part. The recorded thermal history is then compared to the previously-recorded thermal history of the master model. Significant deviations in thermal history are indicative of irregularities in the manufacturing build, and the part quality may then be assessed in view of those irregularities.
