LAYERED CONSTRUCTION DEVICE AND LAYERED CONSTRUCTION METHOD FOR ADDITIVE MANUFACTURE OF AT LEAST ONE COMPONENT AREA OF A COMPONENT

摘要

The invention relates to a layer construction method for the additive production of at least one component region of a component (26), in particular of a component (26) of a turbomachine. The layer construction process comprises at least the steps of a) applying at least one powder layer (P) of a material (W) to at least one assembly and joining zone (A) of at least one lowerable construction platform (16), b) locally solidifying the material (W) to form it a component layer (10) by selectively exposing the material (W) to at least one energy beam (E) according to a predetermined exposure strategy, c) lowering the build platform (16) layer by layer by a predefined layer thickness and d) repeating steps a) to c) to to complete the component area. Subsequent to at least one of steps a) to c), a result of the step in question is determined and evaluated by means of a monitoring system (24), according to which at least one correction intermediate step e) is carried out to improve the determined result, if the evaluation determines an impermissible deviation of the determined step Results from a given result for that step. The invention further relates to a corresponding layer construction device.
