This paper presents the development of stable modes of additive technology of direct laser growing, using the starting material - a metal powder made of heat-resistant EP648 alloy of Russian production. The subsequent heat treatment of the manufactured samples was tested in order to avoid the formation of cracks in the structure of the material formed as a result of the presence of internal stresses after surfacing. Recommendations for further research are given.
