The Combined process of 3D printing and joining for manufacturing multi-material parts made of plastic and metal was developed. In this process, the lower plastic part having a projection is printed, the metal part having a hole sets on the plastic part and then the upper plastic part is deposited on the metal part, while caulking is formed by 3D printer. The effect of the height and clearance of caulking on the joint strength was evaluated by the tensile shear and three-point bending tests. It was found that squashing of the projection of lower plastic part by the upper part was important to obtain sufficient strength. Although the large clearance is facilitate locating of the metal part, the strength is decreased with increasing the clearance.
