Powder bed fusion-laser beam prepared Ti-6Al-4V/Ta bimetals can be well-suited for advanced biomedical applications. However, a few issues remain unsolved, including (a) understanding of residual stress distribution and its level in as-printed bimetal; and (b) wear and bio properties of the bimetal. This study aims to address these points through a series of investigations, including residual stress analysis by neutron diffraction, printing optimization, and analysis of heat treatment effect on
