Abstract: In a method for additively manufacturing at least one metallic and/or ceramic component, comprising a) additively building up at least one green part in an additive printing device from a material composition comprising particles of metal and/or ceramic and an organic binder, b) debinding the at least one green part, and c) sintering the at least one green part to obtain the component, the particles are provided with at least one barrier layer enveloping them.

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.
