吸湿性による3Dプリント造形物のサイズ・質量変化

抄録

3D printer plays in various fields, and study on strength and molding accuracy of 3D printed objects are being conducted. However there has been almost no study on changes in size and mass due to hygroscopicity. In this study, changes in size and mass of 3D printed objects that absorbed moisture have been measured. Based on these results, we have analyzed the tendency of size and mass changes and shown the tendency of size shrinkage to change depending on the amount of moisture in the modeled object. We have also confirmed the characteristics of size and mass changes depending on the internal structure differences.
