英文要約Title:SIP (Cross-ministerial Strategic Innovation Promotion Program) / Innovative Design/Manufacturing Technologies, Manufacturing Initiative through AM innovation (FY2014-FY2018) FY2017 Annual Report

Despite high expectation for manufacturing innovation triggered by additive manufacturing, its outlook is still unclear. To realize the innovation through the technology, this project will overcome the obstacles in front of that. In the project, we will make three improvements in process capability, product concept and design tool. Results of 2017 FY are following.

1. Improvement in process capability
An additive manufacturing process of polyetheretherketone (PEEK) as a high-end super engineering plastic was developed. Resultantly, a high tensile strength of more than 90MPa was obtained reaching the equivalent value out of conventional processes such as injection molding.
2. Improvement in product concept
Design optimization of a socket for a running specific prosthesis using CAE technology was carried out to reduce its weight. Thanks to high compatibility to freeform fabrication of additive manufacturing, a prosthesis lighter than the typical one used in Paralympic games was successfully prototyped although the design cannot be materialized by any conventional processes due to its high complexity.
3. Improvement in design tool
A function of designing prosthesis socket to fit other parts than the sockets was developed for prosthesis design tool having developed in project. Standardized test, ISO 10328, and test use for one week was carried out to show reliability of prosthesis from this technology. A novel functionality that can adopt analogue information indicating such information as positions of bones and muscles was also developed to improve usability of the design tool.
