| 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.
