Under the close and organic cooperation among the nine originally-participating facilities, the R&D goals that were initially defined have been accomplished without delays. Moreover, many tasks are progressed ahead of schedule.
For this SIP program, the Osaka University Anisotropic Design & AM Research Center (OSAKA-ADAM center) was founded in Osaka University Suita Campus on December 1, 2014. As of March 31, 2015, over 40 members including faculties, invited professors and researchers, and research associates gather to accelerate the R&D of this program. Moreover, powder-based additive manufacturing (AM) systems specially designed for fabrication of hardly workable materials as well as 3D printers for rapid prototyping were installed. Thus, the R&D system is being rapidly established.
For achieving products with high added values, the automated optimization software for the anisotropic and customized design was frameworked as planned. The optimization of material and shape parameters is a key strategy in our optimized design. The primary achievements obtained under this strategy are as follows. In home electronics field, thermoelectric capacity of the cooling device element was greatly improved by 30% comparing to the conventional product by the establishment of a kind of novel directional solidification process, which is the goal for the next year (FY2015). In health care field, a bone plate for companion animals is being designed. For realizing the system that enables to rapidly deliver a shape-customized bone plate after diagnosis of bone fracture, in vivo micro X-ray CT was utilized for bone plate modeling in CAD and network system was established between animal hospital and implant manufacturer. In aerial and energy field, fabrication accuracy of a cooling hole in turbine blade by AM that greatly affects heat exchanging performance was improved appropriately.
The assessment of users’ delight is also important concept in this program. One noteworthy finding for objective index in this year was the anisotropic arrangement of apatite crystallite in bone that regulates bone strength more than bone density. This index was proven to sensitively change after short time (~8 weeks) metallic bone plate insertion using an animal model. This finding is the part of goal for the next year (FY2015). For other products, also, promising candidate indices for assessing the delight have been considered. Such indices that assess users’ delight were defined as “Delight Assessment (in Japanese)” which was applied for a trademark registration from Osaka University on December 12, 2014.
Finally, the web page (http://www.mat.eng.osaka-u.ac.jp/sipk/) was released on March 18, 2015, to transmit our concept and achievements toward the public. We are additionally managing web page for Kansai SIP Cluster (http://www.mat.eng.osaka-u.ac.jp/sipdelight/) made up of five bases including ours from January 20, 2015, to enhance cooperative partnership among the cluster members.
