<p><P>PROBLEM TO BE SOLVED: To provide a metal powder for metal stereo lithography in which, even if being subjected to screening for passing the metal powder through meshes for utilization, powder components with a low specific gravity are not scattered, and blended components are not varied. <P>SOLUTION: The metal powder for metal stereo lithography is composed of a powder having a composition comprising iron based powder, both or either of nickel and nickel based alloy powder, both or either of copper and copper based alloy powder, and graphite powder, and is alloyed by a mechanical alloying process. Since the invention is made into the powder in a state where all the metals are layered, and the graphite powder with a low specific gravity is also integrated with the other metals, even in when the same is screened and is reutilized, the scattering of the graphite powder can be prevented. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
