Abstract
Additive technology is a promising direction in the development of industries such as the high-
precision engineering and Aircraft engine building. At the same time, the high cost of 3D printing
process and the lack of alternative (spherical powder) raw materials prevents the wide
dissemination of these technologies. In this paper, the possibility of using cheaper powder materials
based on titanium with particles of non-spherical shape, obtained by hydrogenation-
dehydrogenation technology and intended for the three-dimensional products production by various
methods of additive technologies is shown. The possibility of using different energy sources to
build layered material in the formation of products is considered. The optimal modes of process of
step fusing of thin layers of powdered materials are settled. Advantages of offered powders in
comparison with applied today powders of spherical shape are described. The results of
metallographic investigation of samples derived from the experimental powders are presented.
