Abstract

The present invention relates to a device for laser-based generative component production. The device comprises a processing head (1), using which a plurality of mutually separate laser beams are directed adjacently and/or overlapping to some extent onto the processing plane, The processing head (1) is moved across the processing plane using a movement apparatus (9), while the mutually separate laser beams are modulated independently of one another in terms of intensity, in order to obtain the desired exposure geometry. The laser power and the dimensional size can be scaled cost effectively during the generative production using the suggested device and the associated method.
