Abstract

A method for additive production and a correspondingly produced component made of a powdery base material, includes the thermal pre-treatment of the base material at a first temperature of at least 800° C. under an inert gas atmosphere, wherein the first temperature and a duration of the pre-treatment are further selected such that no sintering process of the base material occurs, subsequent cooling of the base material, and additive construction of the component from the thermally pre-treated base material. A corresponding device is for the additive production.
