Tohoku University in Japan discovers that 3D printers can be used to control the orientation of atoms

The research and development team of Professor Chiba Akihiko of the Institute of Metal Materials of Tohoku University and others found that when the medical cobalt-chromium alloy powder was processed by a 3D printer using the electron beam molten metal forming method, the cycles of the atoms were arranged neatly. Medical cobalt-chromium alloys are materials used in artificial hip joints and the like. Since anisotropy can be imparted to material properties such as elastic modulus in all crystallographic orientations, it is possible to design artificial joints that take full advantage of anisotropy. Chiba's research team believes that other alloys also produce this phenomenon, so it is expected to be applied to the molding of other metal parts such as engine turbine blades.
