Additive Manufacturing of NiTi Shape Memory Alloy for Biomedical Applications: Review of the LPBF Process Ecosystem

NiTi shape memory alloys (SMAs) are used in a broad range of biomedical applications because their unique properties including biocompatibility and high corrosion wear resistance as well functional such superelasticity the effect. The combination SMAs additive manufacturing can lead to revolutionary changes uses industry. This article discusses potential that benefit from AM process. We share lessons learned processing with focus on laser powder bed fusion (LPBF) technique. manufacturability, build quality, stable phases transformation temperatures, microstructure, thermomechanical properties, microstructure tailoring, produced via reviewed. Current challenges expanding process window, controlling chemistry, performance property responses discussed, opportunities alloy design discussed.
