NiTi alloys due to their unique features such as shape memory effect and superelasticity, have extensive applications in variety of technical fields. Several of the defining parameters of these alloys such as transformation temperatures, strength and ductility are highly dependent on thermal treatments and composition. In this paper to overcome the conventional fabrication challenges of NiTi, Selective Laser Melting (SLM) is used. SLM allows for production of complex structures such as patient-specific medical devices. Furthermore process parameters of SLM can be altered during the fabrication to create functional variations in a single part. The present work focuses on developing a systematic approach to investigate transformation temperatures, shape memory effect and superelasticity of dense and porous SLM NiTi alloys. In addition post processing heat treatments techniques has been employed to achieve superelasticity at different temperatures including room and body temperatures for potential biomedical applications.
