Abstract

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 the layer in predefined regions for the layer-by-layer buildup of the three-dimensional object or for the layer-by-layer repair of individual regions of the three-dimensional object within the construction chamber, and at least one inlet nozzle and at least one suction nozzle for a process gas, wherein the inlet nozzle and the suction nozzle are arranged in such a way that a gas flow that passes at least partially over a construction platform formed in a construction chamber is created.
