The present invention reproduces the object to be collated based on a portrait by using a metal material such as bronze, brass, copper, etc., thereby giving a three-dimensional visual beauty as well as a representation of a more authentic person, A method of manufacturing a metal-made ashtray, which is constructed so as to be positively protected from corrosion, discoloration and deformation due to characteristics of a brass or bronze material, And outputting a three-dimensionalized tangible object 10 corresponding to the portrait of the person based on the real photo information by modeling the tangible object 10 by a program, and a step of processing the surface of the tangible object 10 to correct the roughness of the surface A step of finishing a colliding object； (10) on a mold plate (30) made of a rubber material in which at least one hollow wax bar (20) made of a paraffin material is formed, A step of receiving a flake 40 made of a ferrous material and sealing the flake 40 with a sealing member 50； A step of introducing a gypsum liquid into a space for accommodating the flask 40 and the mold tray 30 and removing bubbles generated when the gypsum liquid is introduced by operating a vacuum deaerator for imparting vibration in a vacuum state； And the flask 40 and the mold plate 30 are placed in the firing kiln 60 and heated for a predetermined time to melt the fake article 10 and the wax rod 20 into the inner space of the gypsum The flask 40 is inverted upside down so that the cavity of the gypsum is upward, and the metal flask is put into the calcining kiln 60 again, and the metal liquid is injected into the hollow of the gypsum (50) is removed from the flask (40) to maintain the open state of the through hole, and then the flask is dropped into the cold water, so that the internal penetration of the cold water is performed through the through hole, And a metallic auxiliary tongue removing step of obtaining a metallic tongue 70 due to cooling and fixing and bon
