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: The present invention relates to a method and a system for recycling of remaining powder from an equipment for generatively manufacturing three-dimensional objects (3), wherein, in addition to sieving of remaining powder (3a) or mixing the remaining powder (3a) with fresh powder, a further preparing step for modifying a characteristic of the resulting powder is performed.
