Patent number: 11904413Abstract: Sensor values captured by a sensor device are determined, one or more regions of a three-dimensional component having a deviation from an intended value are determined based at least in part on build coordinates for additively manufacturing the three-dimensional component corresponding to the sensor values, and a quality of the three-dimensional component is evaluated based at least in part on the one or more regions of the three-dimensional component having a deviation from the intended value. The sensor values correspond to an electromagnetic spectrum emitted by a melt pool formed by exposing a powder bed to a beam of radiation emitted from a laser apparatus, with the beam of radiation generating the melt pool in a melt region of the powder bed.Type: GrantFiled: March 7, 2022Date of Patent: February 20, 2024Assignees: Concept Laser GmbH, Katholieke Universiteit LeuvenInventors: Frank Herzog, Florian Bechmann, Sebastian Berumen, Jean Pierre Kruth, Tom Craeghs

Publication number: 20180169948Abstract: 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.Type: ApplicationFiled: June 11, 2016Publication date: June 21, 2018Inventors: Sam COECK, Piet VAN DEN ECKER, Tristan KUYPERS, Michel JANSSENS, Tom CRAEGHS
