1. A method for separating excess material from an additively manufactured component, the method comprising:
a) moving, for purposes of separating the material, the component by a movement device that is controllable on a basis of movement data, and measuring a fill level of the component with material;
b) simulating a process for emptying material from the component for each of a number of different initial fill levels of the component with material, wherein movement data that specify a simulated movement of the component and a simulated fill level progression emerging from the simulated movement are in each case assigned to the respective initial fill level;
c) selecting an appropriate initial fill level depending on the measured fill level;
d) driving, the movement device on the basis of movement data assigned to the selected initial fill level;
e) remeasuring the fill level and comparing the fill level to a simulated fill level progression assigned to the selected initial fill level; and
f) repeating method steps c) and d) depending on the comparing.
