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-by-layer construction method for the additive manufacture of at least one region of a component. The layer-by-layer construction method comprises at least the following steps: a) application of at least one powder layer of a metallic and/or intermetallic material onto at least one buildup and joining zone of at least one lowerable building platform; b) layer-by-layer and local melting and/or sintering of the material for the formation of a component layer by selective exposure of the material with at least one high-energy beam in accordance with a predetermined exposure strategy; c) layer-by-layer lowering of the building platform by a predefined layer thickness; and d) repetition of steps a) to d) until the component region has been finished. The invention further relates to a layer-by-layer construction apparatus for the additive manufacture of at least one region of a component by an additive layer-by-layer construction method.
