Outline of Final Research Achievements

We challenged the development of metal implant materials for bone replacement that is recognized as bone itself by controlling the anisotropies of shape and microstructure under a metal additive manufacturing technology. For the shape control, arbitrary configuration of solid part enabled control of wide range of Young's modulus with isotropic and uni-, bi-, and tri-axial anisotropies. For the microstructural control, crystallographic texture was controlled by scan strategy of heat source. <001> preferential orientation was realized, which resulted in low Young's modulus in the <001> oriented direction. We achieved a highly functionalized implant materials under additive manufacturing controlling the shape and microstructural anisotropies.
