Abstract
A component is produced in layers by laser melting. A molten pool is created in a bed of powder by a working laser beam. Further auxiliary laser beams are set to a power density that merely slows down the cooling of the material in one zone, but do not cause any renewed melting. In this way, the cooling rate of the microstructure can be set so that an advantageous structural formation develops. This allows for example the mechanical properties of the component produced to be advantageously improved without downstream heat treatments.
