PRODUCTION OF A COMPONENT BY SELECTIVE LASER MELTING

摘要

A method for producing a component by selective laser melting, wherein a number of lasers arranged next to one another generate a laser field, as a result of which powdery material can be melted in a selective manner for the purposes of generating contours. In the process, individual lasers of the laser arrangement can be switched on or off in a selective matter in order to irradiate or not irradiate certain regions. Furthermore, a device for carrying out the method is provided.

1. A method for producing a component by selective laser melting, comprising the following steps:
S1) providing a building platform in a manufacturing cylinder; S2) applying a certain amount of a powdery material on the building platform; S3) distributing the powdery material over the building platform; S4) locally fusing powder particles by an action of a laser beam; and S5) lowering the building platform; wherein steps S2)-S5) are repeated a number of times, as is required for completing the component, further wherein a laser arrangement including a number of lasers is arranged next to one another to direct the beams thereof onto a region to be irradiated in such a way that the irradiated region corresponds to a rectangular area.
