Zusammenfassung:	The present invention relates to a method for the tool-free removal of support structures in the additive manufacturing of one or more components. The components are built in layers together with support structures for supporting regions of the components, and the support structures are removed from the components after a complete construction of the components. The support structures are constructed in such a manner that they have target separation points at a transition to the components, which have a structure that breaks down more rapidly by chemical or electrochemical reaction compared to component parts. The support structures are then separated from the components by chemical or electrochemical breakdown of the structure at the target separation points. With this tool-free removal of the support structures, the components can be both arranged in parallel and also completely automatically processed.
