Abstract Additive manufacturing emerges as an innovative technology to fabricate medical stents used to treat
blocked arteries. However, there is a lack of study of underlying microstructure and mechanical properties
of additively manufactured stent. In this work, additively manufactured 316L stainless steel stent was
investigated, with electrochemical polishing being used to improve the surface finish. Microstructural
characterisation was carried out using optical microscopy, scanning electron microscopy, and electron
backscatter diffraction. The hardness and elastic modulus were measured using Berkovich nanoindentation,
with an emphasis on the effect of grain orientation. In addition, spherical nanoindentation was used to
obtain indentation stress-strain curves based… More >
