发明名称 DEVICE AND METHOD FOR GENERATIVE COMPONENT PRODUCTION
摘要 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), whilst 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.

主权项 1. A device for generative component production, particularly for selective laser melting or laser sintering, with a processing head, using which a plurality of mutually separate laser beams can be directed adjacently and/or overlapping to some extent onto a processing plane, a laser beam source arrangement, using which the mutually separate laser beams can be generated, an apparatus for providing a material in the processing plane, a movement apparatus, using which a relative movement between processing head and processing plane can be generated in mutually parallel planes, and a control apparatus, using which the movement apparatus for generating the relative movement can be controlled and the mutually separate laser beams can be modulated independently of one another in terms of intensity, wherein the processing head has one or a plurality of focussing optical systems, through which the laser beams can be focussed in the direction of the processing plane, and the control apparatus is constructed in such a manner that it modulates the intensity of the laser beams as a function of a predetermined component geometry in each case, and wherein an apparatus for gas supply and/or gas exhausting is coupled to the processing head or fastened on the processing head and thus moves simultaneously with the same.
