In this work, thermodynamic calculations are carried out using the Thermo-Calc software for α + β Type Ti–Fe–Cu–Sn alloy. Powders from alloy were obtained by plasma sputtering subsequent 3D printing of experimental samples them. The effect various selective laser melting (SLM) parameters on porosity and hot cracking susceptibility has been studied, electrochemical characteristics have also studied. optimal technological regime manufacture SLM method was determined. It established that to obtain relatively dense without cracks, regimes with volumetric energy density Ev = 250–300 J/mm3 required. A relationship formation a nonequilibrium Ti2Cu phase change in behavior Ti94Fe1Cu1Sn4 Directions further research determined recommendations given.
