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.

Abstract: In a method for additive manufacturing of at least one metallic or ceramic component, before at least one green part is built up layer by layer in a printing device, a support layer is applied to a surface of a printing support having recesses, so that the green part is built up layer by layer on the support layer, whereupon the green part lying on the printing support is removed from the printing device and unpolymerized material is removed from the green part, wherein removed material is collected in the recesses of the printing support or is drained off through the recesses, and wherein the cleaned green part is debinded and sintered.
