SYSTEM FOR THE ADDITIVE PRODUCTION OF A COMPONENT, LAYER APPLICATION DEVICE FOR A SYSTEM, AND METHOD FOR THE ADDITIVE PRODUCTION OF A COMPONENT

摘要

The invention relates to a system (1) for the additive production of a component (2). The system comprises a layer application device (3) for applying powder layers (4) made of a pulverulent starting material (5) on a layer construction zone (6) of a construction platform (7) in layers and a radiation source (8) for generating a high-energy beam (9) in order to solidify the powder layers (4) in the region of the layer construction zone (6). The layer application device (3) comprises two distribution elements (10, 11), each of which has a through-opening (12, 13) for the passage of the starting material (5) in the direction of the layer construction zone (6). Using a moving device (14), the distribution elements (10, 11) can be moved relative to each other such that the through-openings (12, 13) for the passage of the starting material (5) in the direction of the layer construction zone (6) overlap in some regions. Additional aspects of the invention relate to a layer application device (3) for such a system (1) and to a method for the additive production of a component (2).
