Abstract: PROBLEM TO BE SOLVED: To provide a process in which electromechanical parts can be proto- typed by using the three-dimensional printing technology. SOLUTION: This method comprises a step in which a first type powder material 62 is deposited in a specified area to form a first layer, a step in which a binder material is added to the specified area of the first type powder to regulate a part of a structure to be formed, and a step in which a part of a non-adhered powder is removed in a final stage by using the technology such as evacuation. The above-described steps are repeated sufficient times in order to form a desired shape of the structure regulated in the area to be held by the binder material.
