1. A method for producing an object by generative manufacturing by building up the object in layers, the method comprising:
building up a plurality of layers to form a supporting structure that supports at least one overhanging section, to be generated, of the object by the supporting structure;
wherein the plurality of layers comprises a first layer, a second layer, and a third layer;
wherein the first layer comprises a plurality of arches built up on a base;
wherein the second layer comprises a plurality of arches that are built up on top of the plurality of arches of the first layer;
wherein the third layer comprises at least one arch that is built up between the at least two arches of the second layer; and
wherein each arch of the plurality of arches of all of the first layer, the second layer, and the third layer is formed by arch segments which converge substantially in a buildup direction of the object and meet at a tip of the arch;
wherein the plurality of arches of the second layer comprise at least two arches that have different heights from each other;
wherein the at least two arches of the second layer are each connected to and extend away from, in the buildup direction, a corresponding tip of the plurality of arches of the first layer; and
wherein the at least one arch of the third layer is built up on mutually facing arch segments of the at least two arches of the second layer.
