The use of copper alloys in selective laser melting technology will significantly improve the characteristics of radiators. To obtain quality parts, it is necessary to control the resulting metal structure. In this work, we studied the samples obtained on the installation D250 developed by Additive Solutions with a 400 W fiber laser. The article discusses the setting up and running of experiment. The structure of the obtained samples is described and analyzed, its features and the dependences of its characteristics on the modes of the growing process are revealed. The influence of these features on the mechanical properties of parts is discussed. The optimal parameters of the growing process are given and methods for their search are indicated.
