However, in this paper, we demonstrate a high susceptibility of 3D-printed Ti-6Al-4V alloy to hydrogen trapping and embrittlement supported by its specific microstructure. 3D-printed (Selective Laser Melted) and wrought Ti-6Al-4V alloys were electrochemically hydrogenated under the same parameters. In comparison to conventionally prepared wrought alloy, the content of hydrogen trapped in the 3D-printed alloy after electrochemical charging was twofold (5458 ppm vs 2857 ppm, respectively). Heat treatment slightly decreased the susceptibility to hydrogen trapping. Even though, a complete embrittlement was observed for all 3D-printed samples.
