A metal three-dimensional printer, a printing method, and a three-dimensional printing material. The three-dimensional printer includes a printing head, a heating apparatus, a printing platform, and a sintering shaping chamber. The printing method includes a preliminary shaping step and a sintering step. The heating apparatus heats the three-dimensional printing material. A heating temperature of the heating apparatus is 50° C. to 300° C., and a binder bonds metal powder at 50° C. to 300° C., and the three-dimensional printing material is extruded onto the printing platform to form a preliminary cured object. In the sintering step, the preliminary cured object is sintered and cured into a shaped object.
