    摘要: An additive manufacturing machine may include an energy beam system configured to emit an energy beam utilized in an additive manufacturing process, and one or more optical elements utilized by, or defining a portion of, the energy beam system and/or an imaging system of the additive manufacturing machine. The imaging system may be configured to monitor one or more operating parameters of the additive manufacturing process. The additive manufacturing machine may include a light source configured to emit an assessment beam that follows an optical path incident upon the one or more optical elements, and one or more light sensors configured to detect a reflected beam comprising at least a portion of the assessment beam reflected and/or transmitted by at least one of the one or more optical elements. The additive manufacturing machine may include a control system configured to determine, based at least in part on assessment data comprising data from the one or more light sensors, whether the one or more optical elements exhibit an optical anomaly.

    摘要: A process monitoring system for an additive manufacturing apparatus includes a scanner, a sensor device, and an optical focus-tracking device. The scanner includes an optical adjustment device that directs a melting beam emitted by a laser melting device onto a construction plane to generate a melting section of the construction plane. The sensor device may detect reflected radiation from the melting section and generate sensor data indicative of a size, shape, and/or temperature corresponding to the melting section. The optical focus-tracking device includes a focusing lens located between the scanner and the sensor device. The focusing lens may be actuatable by electronic machine data derived from the sensor data to impart a first focus adjustment with respect to the reflected radiation detected by the sensor followed by a second focus adjustment with respect to the melting beam directed by the optical adjustment device.
