英文要約Title: Innovative Design and Production Technology Project under the Cross-ministerial SIP Program Prompt. Development of functional materials and devices by creation of fluidic materials and 3D additive manufacturing (FY2014-FY2015) FY2014 Annual Report

In this project, we aim to apply the ink jet (IJ) three dimensional (3D) printing technology to the structural and functional materials and devices manufacturing process in order to realize 1) significant reduction in time needed for structure building process development, 2) material structure and function implementation without assembling and 3) manufacturing innovation through significant reduction in time needed for production.
It is indispensable to develop methods for functional nano-material synthesis, highly concentrated and highly functional inks (fluidic materials) and nano-processing machine technology for nano-fine processing. It also requires function implementation system using a multi-nozzle IJ unit and an in-situ sintering unit that realize multiple and gradational layers. These fundamental technologies would be necessary for establishment of short time product development base.
In the project, Panasonic Corporation is responsible for the development of the 3D printing system. We focus on the development of the IJ printer heads applicable to concentrated fluidic materials, an in-situ sintering system, a process monitoring system and a feedback control system.
Achievements in FY2014 are as follows.
1)3D printing system control software: The slicing software that gives 2D image data generated from 3D data and the way to transfer the data to IJ heads have been successfully developed by surveying related technologies such as data format, data generation, controlling parameter and IJ head. Then an automated 3D table equipped with IJ heads provided by Toshiba Tec Corporation has been constructed and its operation check has been done.
2)In-situ sintering technology: Inductively Coupled Plasma (ICP) torch sintering that promises low-cost, high-speed and no optical property dependency has been chosen as a result of benchmarking. Dried nano Yttria-stabilized zirconia (YSZ) slurry has been successfully sintered by ICP torch irradiation despite some problems about crack formation due to shrinkage.
3)3D printing base machine: Basic specification of the machine embedded with an IJ head printing unit and a sintering unit has been determined and the conceptual design has been completed.
