1. A method for additive manufacturing of at least one metallic or ceramic component, comprising:
a) building up at least one green part layer by layer in a printing device from a plurality of green part layers, wherein the following steps are carried out for each green part layer:
applying a layer of polymerizable material mixed with ceramic or metal particles to form a material layer, and
location-selectively polymerizing the material layer to obtain a location-selectively polymerized green part layer, leaving an unpolymerized amount of material surrounding the green part layer, so that the at least one green part is obtained in a material block of unpolymerized material;
b) removing the at least one green part from the printing device;
c) removing the unpolymerized material from the green part;
d) debinding of the at least one green part; and
e) sintering of the at least one green part to obtain the component;
wherein
before step a), applying a support layer to a surface of a printing support having recesses, so that the green part is built up in layers on the support layer in step a),
removing the at least one green part from the printing device in step b) while lying on the printing support, and
collecting the unpolymerized material removed in step c) in the recesses of the printing support or draining off said unpolymerized material through the recesses.
