1. A method for separating excess material from an additively manufactured component, wherein
a) spatially resolved structural data relating to the component are received,
b) on the basis of the spatially resolved structural data a process for emptying material from the component is simulated, wherein a sequence of emptying poses of the component is ascertained, and
c) for a respective emptying pose:
the component is moved into the respective emptying pose on the basis of the simulated emptying process,
a material movement is detected by one or more sensors,
a trigger signal is generated as a consequence of the detection of a reduction in the material movement, and
the trigger signal prompts a movement of the component into a subsequent emptying pose, wherein the trigger signal is considered higher priority than the simulated emptying process.
