The present invention relates to a composition containing a metal powder for three-dimensional printing, a three-dimensional printing method using the same as a raw material, and a three-dimensional printing device, which enable a metal product, which requires high precision as well as high strength, to be produced by a three-dimensional printing technique using a raw material containing a metal powder as a feedstock for three-dimensional printing. In particular, the composition containing a metal powder for three-dimensional printing, according to the present invention, is used as a feedstock supplied to an extrusion head of a three-dimensional printer, and is produced by kneading, pulverizing, and pelletizing the metal powder and a polymer binder.
