METAL POWDER FOR SELECTIVE LASER SINTERING, METHOD FOR MANUFACTURING THREE-DIMENSIONAL SHAPED OBJECT BY USING THE SAME, AND THREE-DIMENSIONAL SHAPED OBJECT OBTAINED THEREFROM

摘要

There is provided a metal powder for use in a selective laser sintering method for producing a three-dimensional shaped object, wherein the metal powder comprises a powder mixture of a precipitation-hardening metal composition. In particular, the metal powder of the present invention is configured to have a Fe-based component powder and a Ni-based component powder which are individually included in the powder mixture wherein a powder made of an alloy of Fe-based and Ni-based components is not included as a main powder in the powder mixture.
