摘要：
In the paper, the quality of stainless steel products formation by the electron-beam wire-feed additive manufacturing method was studied. AISI 321 austenitic steel was selected as the material under study. As a result of the research, it was found that two main factors influence the quality of the obtained products. The first factor is the geometrical parameters of the printing process, the disruption of which leads to the deviation from the axis of fabrication. The second factor influencing the quality of steel products is the parameters of the electron beam. Incorrectly selected beam currents or accelerating voltages can lead to changes in the thickness and height of the product walls.
