Abstract Scope Although additive manufactured (AM) Nitinol parts exhibits acceptable shape memory and superelasticity in compression loadings, they provide a relatively weak tensile and fatigue properties in comparison to the conventionally manufactured Nitinol. As a solution to improve the mechanical properties of the AM fabricated Nitinol and to reduce the internal microvoids, we have investigated the effect of re-melting during the SLM procedure after fabricating each layer. A series of re-melting process parameters including different scanning speed and laser powers were studied through mechanical testing, DSC, and SEM analysis. We have shown that proper selection of the re-melting process parameters improves the powder bed quality of each layer, increases the density of the fabricated parts by up to %1.5, and reduces the top surface roughness by up to %50. Improving the density and reducing the internal voids may improve the mechanical properties, and it is also being investigated in this work.
