Abstract
The disclosure relates to processing machines and methods for producing three-dimensional components by irradiating powder with a processing beam, the machines including a container with a moveable support for the powder, as well as an irradiating device with a scanner device for aligning the processing beam on a processing field at an opening of the container. The irradiating device includes a heating device that includes a heating radiation source for generating a heating beam for heating the powder from above and including a beam shaping optical unit configured to convert a first beam profile of the heating beam into a second beam profile, e.g., a ring-shaped beam profile, of the heating beam.
