英文要約Title: Research on Innovative Design/Manufacturing Methodology of Tailor-made Rubber Products and Socio-Economic Value Co-Creation with Reactive 3D printer (FY2014-FY2018) FY2016 Annual Report

The following research results were obtained. (1)The constructed smart factory demo system based on a CPS (cyber physical system) concept and an IoT (Internet of Thing) environment has been expanded and a material ordering planning method using a combined optimization technique has been developed. (2)We conducted an online survey of adoption intentions for smart interactive services in the running context. Three scenarios for smart services were addressed in the survey, and 1,000 samples were collected for analysis. To complement the survey, focus group interview research was conducted with regard to walking shoes with sensing technology. (3)The running motions using the different-type running shoes were measured to analyze the relationship between the running shoes and running motions, and it was revealed that the different-type shoes resulted in the significantly different running risks. The motion analysis results also showed that the different running patterns result in the different running risk even on the same-type running shoes, and we have been developing the running-pattern-recognition system. (4)The update to the system that can continuously evaluate the load change from the heel contact point to the toe take off was carried out. In order to confirm the usefulness of the tailor-made shoe, we made a running shoe with sole parts of different rigidity distribution and shape that are made by 3D printer for the motion measurement mentioned above. (5)We have developed three type of application program that are designed for co-creation between user and producer, and build the network system. We developed “Analyze & Visualize 3D foot model App” and “Store App”. (6)The functional-graded polyurethanes for outer-sole rubbers and the 3D printing ink were evaluated. The outer-sole made by the 3D printer successfully achieved actual running tests requirements. In addition, we have achieved demanded dispensing accuracy for a midsole by a UV curing 3D printing system. The trussed structured midsole was adopted prototype running shoes. (7)By integrating the sensing system and small-size lightweight wireless transmitting device as a smart insole, the running and walking in-situ measurement systems were developed. (8)Reaction characteristics of impinging micro-droplets injected by nozzles have been investigated. The spinning effects of materials injected by nozzles significantly decrease the accuracy of the 3D printing. On this problem, the injection condition and the rheological characteristics causing the spinning effect have been also studied. The size of XYZ table of the rubber 3D printer was increased and improved for stability of rubber materials supply. To lighten the product by formation of 3D hollow structure, we have investigated effects of additives such as factice and thermal expansion microcapsules and foaming the product in vulcanization process after 3D printing.
