N2 - Zr-alloys are occasionally overlooked as candidate materials for orthopaedic implants, despite having elastic modulus and magnetic susceptibility lower than Ti-alloys. In this study, the processability, mechanical properties, and biocompatibility of laser powder bed fusion (LPBF) Zr-702 builds were investigated. Builds with 99.9% density were obtained following process optimisation. The builds demonstrated high tensile properties in both the vertical and horizontal orientations, which exceeded the strength of CP Ti and wrought Zr-702.
