Abstract

The invention relates to a method for producing a body by means of an additive production method (AM) by using metal powder, comprising the following steps: designing the body in a computer-simulated manner while taking into account at least one region of the body to be processed and transferring data to an additive production device, in particular an additive powder-bed production device, successively providing the metal powder in order to construct powder layers arranged one on the other, successively hardening parts of the powder layers in order to form at least one specified structure in the powder layers arranged one on the other, wherein the structure is at least partially filled with metal powder of the powder layers, and calibrating a body, which is created by means of the structure, in the region to be processed. The invention further relates to a corresponding device, to a body produced in such a way, and to a computer program product for performing the method.
