Abstract: A device for the stereolithographic additive manufacturing of metallic components includes a material support for a material layer of a material to be polymerized, the surface of which forms a building plane, a material container for fresh material, which opens into the building plane via a material feed opening, a build platform movable between a position flush with the building plane and a lowered position perpendicular to the building plane, a doctor blade movable between the material container and the build platform for applying the material layer on the building plane, and an exposure unit for position-selective exposure of the material layer on the build platform or on a component partially built on the build platform. The material support is exchangeably arranged in the device.
