Paper Abstract

NiTi alloy has excellent biocompatibility. This paper presents a novel technology of direct shaping of this promising biomaterial with selective laser melting (SLM). The frequently encountered defects of the SLM metal alloy parts such as non-fully melting, thermal deformation and balling were analyzed theoretically and experimentally, and the microstructure of the parts was analyzed on microscope. The results show that an appropriate selection of laser mode and scanning strategy assures a satisfying quality of the final parts; they also reveal that the SLM technology can be expected as a potential technology to directly manufacture the artificial implant of NiTi alloys.
