Vorrichtung zur generativen Fertigung eines dreidimensionalen Körpers in einem Pulverbett mit mehreren Rakeln

Abstract

The invention relates to a device for the generative production of a three-dimensional body in a powder bed having a production region, which has a lowerable surface on which the powder bed is arranged, and having a plurality of doctor blades for uniform distribution of a supplied powdery material over the surface of the powder bed. The device furthermore has an apparatus for carrying out translational movements of the doctor blades over the surface of the powder bed, and an apparatus by means of which at least one energy beam is directed onto the surface of the powder bed, the focal spot thereof being movable in two dimensions
