A powder build unit for a device for the additive manufacture of components, includes at least one electric lead and having at least one power source that is connected to the electric lead. The electric lead functions as a powder distributor and as a heating element. In addition, a device that contains this powder build unit, as well as a corresponding method of using the powder build unit, is disclosed.

Powder build unit, corresponding device, and method employing a powder build unit

The invention relates to a device for the manufacture or repair of a three-dimensional object, comprising at least one construction chamber for a successive solidification of at least one solidifiable material layer by layer in predefined regions for layer-by-layer buildup of the three-dimensional object or for layer-by-layer repair of individual regions of the three-dimensional object inside of the construction chamber, at least one coater that can travel for deposition of the material on at least one buildup and joining zone of a construction platform formed in the construction chamber, at least one inflow nozzle and at least one suction outlet nozzle for a process gas, with the inflow nozzle and the outlet nozzle being arranged in such a way that a gas flow that passes at least partially above the buildup and joining zone is created, and at least one overflow tank.
