Layer manufacturing and Schichtbauvorrichtung for additively producing at least a component region of a component

2016 
The invention relates to a construction method for additively producing layer of at least one component region of a component (10), particularly a component (10) of a turbomachine. In this case, the material is heated to a predetermined first temperature be at least the steps a) applying of at least a layer of powder of a material at least one assembly and joint zone at least a lowerable building platform (12), b) layer-by-step and local melting and / or sintering, the tempered material for forming a device layer by selectively exposing said material with at least one high-energy beam according to a predetermined exposure strategy, c) layer-by-step lowering the build platform (12) to a predefined layer thickness and d) repeating steps a) through d) until completion of the component region carried out. Before step b) at least one image of the tempered material is acquired using a camera system, wherein the image characterizes a temperature and / or temperature distribution of the material in the field of construction and joining zone. By means of a computing device is determined based on the acquired image, the exposure strategy for at least one following device layer and / or adjusted. The invention further relates to a Schichtbauvorrichtung for additive manufacturing at least one component region of a component (10) by such an additive layer manufacturing.
