英文要約Title: Establishment and Validation of the Base for 3D Design & Additive Manufacturing Standing on the Concepts of Anisotropy & Customization (FY2014-FY2018) FY2016 Annual Report.

・We found out that both scanning rate and scanning width of laser bean in additive manufacturing (AM) are main factors for crystal orientation control in Ni-based heat resisting alloy, and realized the creation of crystal orientation controlled built with optimal built condition. In addition, an approach with a seed crystal for achieving crystal orientation control further intentionally was undertook to confirm its effectiveness, which established one of fundamental technologies for crystal orientation control.

・Then, we clarified the process parameter (beam type, power, scanning width, layer thickness) region, which achieves a built with low porosity and high size precision, for ー type Ti alloy expected as biomaterial etc. In addition, we verified that the beam scanning pattern can control the atomic arrangement, i.e. texture, with a significantly high degree of freedom. Then, it was confirmed that the growth of this texture gives a low elastic modulus (young modulus) in a specified direction, viz. anisotropic material properties. Furthermore, we successfully realized the world’s first both shape and material controls in MoSi2 expected as next generation ultra-high temperature material.

・A 60% increase, which is higher than initial target value, in performance was achieved by improving anisotropic design. The developed anisotropic custom thermoelectric device is placed as a temperature controlling element of optical communication module laser diode at the commercialization stage to improve power consumption by 40 % in comparison with a conventional one.

・We succeeded the world’s first animal implantation test with custom titanium bone plate, which is designed by automated shape design tool and fabricated by AM. The fracture reduction surgery with this implant took only 45 to 60 min because of no plate bending process and the ideal arrangement of screw holes for fracture reduction. The custom bone plate can decrease the surgery time by 30% in comparison with conventional commercial bone plate.

・We carried out test use of prototype of developed software for custom lampshade design for specified 30 extreme users. Additionally, a “delight” lampshade prototype by reflecting minority element was manufactured based on the detailed analysis of results of an about 2 months online questionnaire given to 400 persons.

・We established a delight design team in Technology Research Institute of Osaka Prefecture to develop navigator human resources for strengthened system of upper stream support, and installed “Topology Optimization Program (Prof. Nishiwaki Laboratory in Kyoto University)” to finish the environmental arrangement of test use for small and medium-sized enterprises.
