Abstrakt: Abstract: Samples of unalloyed titanium VT1-0 with high strength characteristics (ultimate tensile strength of 820 MPa), which exceed the values for this material manufactured using conventional technologies, are produced by selective laser melting. To solve the problem of replacement of titanium alloys with commercially pure titanium in medical applications, unalloyed titanium VT1-0 with record mechanical characteristics (ultimate tensile strength of 1350 MPa) is processed by selective laser melting and rotary swaging. This value exceeds the characteristics of the high-strength Ti–6% Al–4% V alloy. The finely dispersed martensite formed as a result of high crystallization rates under the optimal mode of selective laser melting is the reason for the strength characteristics increase of unalloyed titanium VT1-0.
