摘要： Additive manufacturing systems may include a laser melting apparatus, a sensor device, and a visualization apparatus. A laser melting apparatus may form a three-dimensional component by exposing a powder bed to a beam of radiation based on build coordinates, with the beam of radiation providing an energy influx that generates a melt pool in a melt region of the powder bed. A sensor device may capture sensor values corresponding to the melt pool and/or the melt region. A visualization apparatus may display a representation of the three-dimensional component, with the display including the build coordinates and the sensor values in respect of a capture location thereof in the three-dimensional component. The displayed representation may be based on a display output that includes sensor values correlated with build coordinates.

摘要： 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.

摘要： A method for producing a three-dimensional component by means of a laser melting process, in which the component is produced by consecutively solidifying individual layers made of building material by melting the building material, wherein said building material can be solidified by the action of radiation, wherein the melting area produced by a punctiform and/or linear energy input is detected by a sensor device and sensor values are derived therefrom in order to evaluate the component quality. The sensor values detected in order to evaluate the component quality are stored together with the coordinate values that locate the sensor values in the component and are displayed by means of a visualization unit in two- and/or multi-dimensional representation with respect to the detection location of the sensor values in the component.
