| <Abstract> 利用双光子引发光聚合的微光立体光刻技术是利用激光的超高清晰3D打印技术. 因为此技术可以自由地实现超过光衍射极限的次100纳米级别的3维结构,故在纳米光子学,微米机器,生物等领域中得到了广泛应用. 本文介绍了双光子微光立体光刻技术的原理与特征,并对其最近的研究动态进行了说明. Keywords: 3D Printing / Microstereolithogrphy / Photopolymer / Two-Photon Absorption / Molding / Optical Trapping / Microfluidic Devices |

| 以制备生物体组织为目标的3D生物打印技术的开发 | 荒井健一, 中村真人 |
| <Abstract> Biological tissues and organs are consisted of three dimensional (3D) structures with several types of cells and extracellular matrices. It is one of the biggest challenges in tissue engineering to construct such 3D biological structures by every means applying manufacturing technologies. Then, we found the big potentials of inkjet technologies in tissue construction such as multi-color printing and high resolution printing with micro-sized ink droplets, we have developed a custom-made inkjet 3D-Bioprinter, which enable to fabricate complicated 3D hydrogel structures including living cells by layer-by-layer printing. As a result, the feasibility of direct cell printing and 3D laminating has been shown, and the concept of computer aided tissue engineering, in which biological tissues are designed in computer and fabricated by 3D-Bioprinter, could be proposed as a next generation tissue engineering approach. In future, we expect that 3D fabricated tissues produced by several engineering techniques including 3D-Bioprinting can contribute to the development of innovative clinical therapeutics for intractable diseases and organ failure.

| 3D凝胶打印机 | 宫 瑾 |
| <Abstract> Current commercial 3D printers are almost exclusively used for printing plastic or metal. 3D printers for forming soft material gels have not been found in the market. Freeforming of gels is quite difficult due to their two unique properties of softness and swelling. In our group, two kinds of 3D printers for freeform fabrication of gels and soft food were developed, a bathtub-type gel printer named SWIM-ER, and an ink-jet-type food printer named E-CHEF. The valve of blood vessel, which is hard to build by soft materials, is printed successfully with gels by SWIM-ER. We also succeeded in preparing the Japanese traditional dish rice balls by the food printer E-CHEF. The 3D gel printers allow us to combine the synthesis and freeform technology for gels. These combination would initiate paradigm changes not only in the chemistry field but also in the mechanical field. The true creative manufacturing, designing and making only for an individual, is supposed to be realized perhaps surprisingly soon.

| 热可塑性树脂的FDM3D打印机技术及应用 | 丸冈浩幸 |
| <Abstract> So called “3D-printers” consist of a lot of technologies, machines and materials of Additive Manufacturing. FDM stands for Fused-Deposition-Modeling. It is one of the major processes of 3D-printing. FDM can produce engineering thermoplastic parts without molding, hence it is useful for prototyping and Direct-Digital-Manufacturing in many fields.

| 3D打印机市场与研究开发动向 | 辻 早希子 |
| <Abstract> 3D printing is currently a hot topic. It is an automatic process to create objects from various kinds of materials, such as metals, plastics, papers, and ceramics. The global 3D printing market is growing rapidly and reached over $2 billion in 2012. But while 3D printing is believed to be the next industrial revolution, in reality there are still technical issues to be solved. This report provides current information on technical description and issues, market trends, and statistical analysis of patents and research papers of 3D printing worldwide. The analysis of patents indicated the companies in Europe, USA, and Japan are the major R&D players. On the other hand, the statistical analysis of research papers showed, in addition to Europe and USA, China and Korea put considerable effort in academic research. The number of published papers on this area has been continuously growing since 2001. This suggested 3D printing has attracted increasing attention as reseach themes. Keywords: Additive Manufacturing / 3D Printing / Market Trend / Patent Analysis / R&D Trend |

| <Abstract> The author has learned one possible way to establish himself as a researcher in polymer science from iaidō: one of the traditional martial arts in Japan (budō). The way may be explained on the basis of the concept “shu-ha-ri.” In this short article, the author gives a brief explanation of shu-ha-ri and of the relation between iaidō training and research training. |

| 生物亲和性高分子的大规模筛选-生物表面水的作用与中间水概念在材料设计中的应用- | 田中 贤 |
| <Abstract> The mechanisms responsible for the biocompatibility of polymers at the molecular level have not been clearly demonstrated, although many theoretical and experimental efforts have been made to understand these mechanisms. Water interactions have been recognized as fundamental for the biological response to contact with polymers. We have proposed the “Intermediate Water” concept, and hypothesized that intermediate water, which prevents the proteins and blood cells from directly contacting the polymer surface, or non-freezing water on the polymer surface, plays an important role in the biocompatibility of polymers. We will provide an overview of the recent experimental progress of the robust screening of biocompatible polymers based on bio-interfacial water structure. Keywords: Biocomaptibility / Water Structure / Protein Adsorption / Cell Adhesion / Intermediate Water |
