The main directions of the development of additive technologies at the Peter the Great St. Petersburg Polytechnic University are considered. Fabrication and research of spherical powders of complexly alloyed alloys for additive production from metal waste and of functionally graded materials with variable structure, chemical composition and porosity, synthesis of intermetallic titanium alloys by selective laser melting are considered among other examples.
