Abstract: A composite equal additive manufacturing method: S1, obtaining molten metal by using a metal smelting device; S2, first, storing inflow molten metal in an intermediate container, and then transferring the molten metal into a crystallizer; S3, cooling the molten metal to a solid-liquid mixed state by using the crystallizer, and enabling a high-temperature blank body with a required section to flow out from an outlet of the crystallizer; S4, arranging plastic forming tools at a bottom of the outlet of the crystallizer, and performing plastic forming on the outflow high-temperature blank body; S5, fixing a lower end of a part after the plastic forming and slowly descending the part by a chuck; S6, machining the part by using point forming machines, and synchronously controlling the machining temperature of the part; and S7, descending the chuck to an appropriate position, and taking the formed part out from the machine frame.
