英文要約Title:SIP (Cross-Ministerial Strategic Innovation Promotion Program) / Innovative Design/Manufacturing Technologies Development of Manufacturing Technology for Innovative Apparatus and Innovation Society from Central Japan (FY2014-FY2015) FY2014 Annual Report

Our group focused on the following goals in FY2014.
(1) R&D for 3D Printing of Metal-Polymer Composite Materials (Nagoya Univ.) Metal-polymer (including metal oxide) composite structures were patterned by direct femtosecond laser pattering. CuO nanoparticles solution film which included CuO nanoparticles, polyvinylpyrrolidone, and reductant agent was heated by focused femtosecond laser pulses on a glass substrate. The film was selectively reduced to Cu and sintered to CuO microstructures by controlling the laser heating temperature.
(2) R&D for 3D Printing of Polymers with Multiple Properties (Nagoya Univ.)
1) Development of 3D printing system. The 3D printing system ejects droplets of PEG-DA, a photo-crosslinkable resin, which are cured by UV light. The Young's modulus was varied from 400 kPa to 25 MPa by controlling the PEG-DA concentration. The shapes of the cured PEG-DA were evaluated.

2) Development of temperature indicator for surgical simulator. The temperature indicator consists of PDMS and a thermochromic pigment. The temperature was evaluated by image processing. The range and accuracy were 50-110°C and 2.0°C, respectively.
(3) Development of model parts for highly realistic surgical simulator (Nagoya Univ., Fin-Biomedical Ltd)
1) Generation of 3D shape data. We generated 3D shape data for a major artery and vein region, in addition to the heart structure with the pulmonary artery/vein for 3D fabrication.
2) Collection of material data. To prepare material data for organ tissue for multi-material fabrication, we evaluated the material properties of heart tissue and plaque. We are identifying appropriate material conditions from the data in collaboration with Nagoya University.
(4) Development of die-free hybrid sheet metal forming technology (Fukui Univ.).
1) Development of incremental sheet metal forming technology. Using existing equipment, incremental sheet metal forming technology for aluminum alloy, magnesium alloy and pure titanium sheets with thicknesses of 0.5, 0.8 and 0.4 mm thickness, respectively, was developed. The maximum height of the formed shape was 20 mm and the maximum difference between objective and formed shapes was 3.2 mm.
2) Formed shape measurement by digital image correlation. Equipment for measuring the 3D shape and strain distribution of formed sheets based on digital image correlation was introduced.
(5) Development of innovation society (The Japan Society of Mechanical Engineers). An innovation society was established in JSME to develop synergy among various players. A committee for promoting society-initiated innovation was established in the innovation center of JSME. It has started to develop an innovation forum and innovation conference system which will be used for the "Innovation from JSME 2015" conference planned for November 2015.
