Beschreibung
Zusammenfassung:	A method for operating a manufacturing device for the additive manufacture of a three-dimensional object, by the layered application and selective solidification of a building material in a building area lying in a working surface, includes directing, by a first scanning unit of the manufacturing device, a detection region of a first sensor unit onto at least one first partial region of a test body region without the first scanning unit directing a beam onto the test body region. The first sensor unit is assigned to the first scanning unit. The method further includes irradiating at least part of the test body region with a beam directed onto the test body region by a second scanning unit of the manufacturing device and evaluating measurement signals detected by the first sensor unit.
