In this work, the authors investigated the physical regularities of the structural-phase and chemical state formation in the volume of 3D printed titanium products consisting of several layers (surface layers of 3D printed alloys in the original and modified state and transition zones surface layers of 3D printed alloys in the original and modified state and transition zones) depending on the applied methods and regimes of obtaining and high-energy processing. The authors of the method provided a physical justification of the effectiveness of the combination of electron beam 3D printing with surface treatment by means of precision gas dynamic 3D printing and laser treatment. It has been established that this approach makes it possible to eliminate the main disadvantages of 3D-printed alloys, which are their structural imperfection, which causes low plasticity, fatigue strength and corrosion resistance. From a fundamental point of view, it allows to give a complete physical picture of the process of forming the structure and physical and mechanical properties of metal materials during 3D printing and to find ways of managing this process.
