Abstract: The invention relates to a manufacturing device for the additive manufacturing of a three-dimensional object and a corresponding method. The object is manufactured by applying a building material in layer-wise form and selectively solidifying the building material at points corresponding to the cross-section of the object. The points are scanned with at least one exposure area, and, during operation, a movable gas inlet approaches a reference process point and/or a target flow supply zone assigned to the reference process point for the flow supply with the process gas, and the process gas is discharged via a stationary gas outlet.

Abstract: Disclosed is a manufacturing device for the additive manufacturing of a three-dimensional object, wherein the object is manufactured by applying a building material layer by layer and selective solidification of the building material, at points in each layer which are assigned in this layer to the cross-section of the object. The points are scanned with at least one exposure area. The movable gas outlet is assigned during operation to a reference process point and/or a target flow supply zone of the movable gas outlet assigned to the reference process point for the flow supply with the process gas and/or the target ventilation zone of the movable gas outlet.
