Abstrakt: In this work, thermodynamic calculations for α + β Type Ti-Fe-Cu-Sn alloy were carried out by the Thermo-Calc software. Powders from this alloy were obtained by plasma sputtering and used for subsequent 3D printing of experimental samples. The effect of various selective laser melting (SLM) parameters on porosity and hot cracking susceptibility as well as the electrochemical characteristics of the alloy have been studied. The optimal technological regime for the manufacture of samples by the SLM method was determined. It has been established that to obtain relatively dense samples without cracks, regimes with volumetric energy density E v  = 250-300 J/mm 3 are required. It has been established that a change in the electrochemical behavior of the Ti 94 Fe 1 Cu 1 Sn 4  alloy is related to the formation of a nonequilibrium Ti 2 Cu phase. Based on the findings we recomended directions for further research.
