Abstract
In this work, we compared the samples obtained by additive technologies. Samples for the study were printed on two different printers using similar DMLS and DMLM technologies. Printing was carried out according to the CAD model data. The printing was performed using the manufacturer’s recommended print settings. For printing, we used powders recommended by the manufacturer for these printer models. In the course of the work, the structure and roughness parameters in the initial state were compared. The heat treatment mode was selected. The effect of vacuum annealing on the structure as well as mechanical properties such as uniaxial tension, KCU and fatigue strength was investigated. Based on the results of the work, a conclusion was made about the improvement of 3D printing, as a result of which the products obtained using additive technologies after heat treatment are not inferior in properties to products obtained using industrial technology from a similar alloy.
