The invention discloses a manufacturing method of a steel piston. The steel piston comprises a 3D printing component and a piston blank part. An inner cooling oil way of the steel piston is independently formed by the 3D printing component or formed by the 3D printing component and the piston blank part jointly. The manufacturing method of the steel piston comprises the following steps that the piston blank part is manufactured, and a supporting platform is formed on the piston blank part; a structural design model of the 3D printing component is completed through a computer in an assisting manner; and the 3D printing component is printed on the supporting platform of the piston blank part through 3D printing equipment. According to the manufacturing method, the 3D printing technology andthe steel piston blank process are combined, and 3D printing forming of the inner cooling oil way structure of the steel piston is achieved; the manufacturing method is simple in process, high in material utilization rate, go
