Claim 0:
1. A method of additively manufacturing a three-dimensional object, the method comprising:
performing, with a coating unit comprising one or more coating elements, a coating process comprising moving across a construction plane within a process chamber while applying sequential layers of a metal powdered construction material to the construction plane;
during the coating process while applying a respective one of the sequential layers of the metal powdered construction material:
detecting, with a detection unit, layer information describing a quality characteristic of the respective one of the sequential layers of the metal powdered construction material, the detection unit being mounted to or structurally integrated into the coating unit such that the detection unit moves with the coating unit relative to the construction plane, and the detection unit comprising an image acquisition unit configured and positioned to detect and acquire the layer information, wherein the quality characteristic comprises smoothness; and
directing, with a radiation-generating unit, an energy beam onto the respective one of the sequential layers of the metal powdered construction material that the detection unit has already acquired the layer information; and

controlling, with a control unit, one or more properties of the energy beam based at least in part on the layer information.
