Abstract: 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.

Abstract: An irradiation device for an additively manufacturing apparatus may include a working beam generation device configured to provide a working beam, a modulation beam generation device configured to provide a modulation beam, and a solid-state optical modulator that includes a crystalline material that exhibits a change in refractive index in response to photoexcitation of free electrons within the crystalline material. The irradiation device may include a power source coupled to the solid-state optical modulator and configured to introduce free electrons into the crystalline material. The modulation beam may cause photoexcitation of the free electrons within the crystalline material. The photoexcitation of the free electrons within the crystalline material may cause the crystalline material to exhibit a change in refractive index. The working beam, when incident upon the crystalline material, may exhibit a change in one or more parameters, such as a phase shift, attributable at least in part to the change in refractive index exhibited by the crystalline material.

Abstract: 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.
