It’s well accepted that the thermo-mechanical properties of Nitinol (NiTi) are strongly affected by the material processing. Additive manufacturing has been recently considered as an interesting technique to develop Nitinol devices with sophisticated geometries, which are impossible or very difficult to be produced through typical manufacturing procedures. In the present work, the effect of energy input on the phase transformation temperatures, as the most critical thermal parameters of the shape memory material, of Nitinol parts manufactured by selective laser melting is investigated and discussed.
