3-D printing techniques induces a change in the manufacturing industry. In particular, the techniques has attracted attention as a next generation manufacturing techniques in jewelry, medical and bio as high value-added industry. The biggest problem in the manufacturing process that utilizes a 3-D printing technology is the mechanical strength. Because it has a method of manufacturing stacked layers in this order, the interlayer strength is pointed out as the biggest problem. In this study, we try to measure these interlayer bonding force and try to analyze the changes in the the strength in accordance with the manufacturing process. |
