More Information
Summary:Generatively producing at least one portion of a component (2), which is constructed from individual powder layers, comprises heating a powder layer to be generated locally on a melting temperature by a first high energy beam (16), forming a molten bath (56), and reheating a zone downstream to the molten bath by a second high-energy beam to post-heating temperature and globally adjusting the component to a base temperature by a heating device (10). An independent claim is also included for a device (1), comprising a first radiation source for emitting a movable high energy beam relative to a generatively produced portion of the component for the local heating of a powder layer at a melting temperature to produce a molten bath, and a second radiation source for emitting movable second high-energy beam for post-heating the zone downstream to the molten bath at the post-heating temperature and for globally adjusting the component to a base temperature by a heating device.
