| Outline of Final Research Achievements |
In this study, we attempted to apply three-dimensional additive manufacturing to production of assistive device components. The anisotropic strength characteristics of the components fabricated by additive manufacturing hamper safety design and use of the 3D-printed products. Then, we systematically investigated strength characteristics of 3D-printer fabricated components dependent on the lamination directions by tensile and flexural testing. The existing surface modification treatments were found to improve tensile and/or flexural strength. The findings experimentally obtained were consistent with the results of the flexural test where a component of an upper-limb prosthesis was tested.
