在这项研究中，多材料零件的制造工艺，同时机械连接和三维（3D）打印的塑料零件的开发。在该过程中，具有孔的金属部件设置在具有突起的下部3D打印塑料部件上，并且上部塑料部件沉积在金属部件上，同时通过3D打印机形成填缝。通过拉伸剪切和三点弯曲测试评估了3D打印条件和填缝尺寸对接头强度的影响。观察到在印刷上部的同时挤压突起有效地提高了强度。随着间隙的增加，强度降低，而突起的形状被改变为圆柱形和圆锥形，以便于定位，同时防止强度降低。
In this study, the manufacturing process of multi-material parts by simultaneous mechanical joining and three-dimensional (3D) printing of plastic parts was developed. In this process, a metal part with a hole sets on a lower 3D printed plastic part having a projection, and an upper plastic part is deposited on the metal part, while caulking is formed by a 3D printer. The effect of 3D printing conditions and a dimension of caulking on the joint strength was evaluated through the tensile shear and three-point bending tests. It was observed that squashing the projection while printing the upper part effectively improved the strength. The strength decreased as the clearance increased, whereas the shape of the projection was changed to a cylinder and a cone to ease positioning while preventing a decrease in the strength.
