ジャーナル フリーFirst, this manuscript discusses the feasibility of 3D printing technologies. Several 3D printing technologies focus on “innovation” as a parameter to enhance production systems as well as creative thinking. Six different factors,“what,” “why,” “how,” “who,” “where,” and “when,” are used to gauge the expected meanings (or values) of innovation based on the viewpoint of 3D printing. Second, this manuscript explores the impact of 3D printing on the psychological aspects of innovation in a society rather than the techniques or skills involved in the process. The term innovation design is used to address the future tendency of manufacturing systems that will enhance current production styles developed for specialized markets that are supported by networks. Further, personalized printing systems may facilitate creativity among people, which in turn will help diversify innovative lifestyles. Finally, some case studies are introduced to allow the reader to imagine possible future society scenarios.抄録全体を表示PDF形式でダウンロード (956K) -

ジャーナル フリーRecently, the degree of attention of 3D printer increases and its use has been spreading. 3D printers taken up here are as follows; stereo lithography, selective laser sintering, ink jet printing, fused deposition molding, and laminated object manufacturing. Can 3D printer change Japan’s manufacturing industry? It is described about the foundation and application whether it is fit for what kind of use. The examples of the application is raised in the following; produce (rapid manufacturing, on-demand parts, inspection), create (model, capture, sculpt), measure (precision metrology, inspection reporting, 3D documentation), prototyping (design verification, functional validation), and others.抄録全体を表示PDF形式でダウンロード (1595K) -

ジャーナル フリーRecently three-dimensional (3-D) printers have attracted much attention due to their abilities to create complex 3-D models with a wide variety of materials. In particular, two-photon microstereolithography using a femtosecond pulsed laser can provide 3-D polymeric microstructures with sub-100 nm feature size. This technique has been applied in wide range of applications such as photonics, biology and micromachines. We have developed optically driven lab-on-a-chip devices such as micropumps and micromanipulators. Recently we have fabricated optically driven metallic micromachines by the combination of two-photon microfabrication and electroless plating. The metallic micromachines can be driven with an ultralow-power laser beam. In addition, we have developed a 3-D molding process using a 3-D polymer mold can provide functional ceramic microdevices. Using this molding process we fabricated several types of functional ceramic microstructures such as transparent silica microchannels, bio scaffolds, and piezoelectric vibration energy harvesters. This 3-D ceramics molding process will make possible to produce complex 3-D ceramics microdevices.抄録全体を表示PDF形式でダウンロード (1203K) -

ジャーナル フリー3D gel printer for manufacturing high-strength gel materials was developed. For innovation of gel-like materials,the development of manufacturing method for gels will be quite important. It is why the 3D gel printer was developed,which makes gel materials 3D-designable. Once the method will be digitalized, the application variety of gel materials will be expanded and accelerated enormously. The 3D-printed foods were proposed by local companies and citizens in Yonezawa City with the collaboration of research groups in other universities under the Center of Innovation (COI) projects of the MEXT. A local fabrication space is being made in the Yonezawa Station, named EkiFab. It will be a kind of Japanese-style makers revolution, started in a local city in Japan.抄録全体を表示PDF形式でダウンロード (2960K)

ジャーナル フリーSeveral unsolved problems experienced by our group were described. The first was concerned about the chemical reactivity of silica in rubber matrix. The oxidation reaction of polyisoprene was promoted by silica particle, however,this was not explained simply by ability of acid catalyst proposed for silica. The second was concerned about the destruction-reconstruction behavior of crosslinking structure by stretching. The broken structure partly recovered in the sample crosslinked by sulfur. However, such behavior was minor in the sample crosslinked by peroxide. The reason was uncertain. The third was stress-strain behavior of elastomer in relation to the changes of network structure. Although existence of inhomogeneous network structure should be taken into consideration, the details were not clear.抄録全体を表示PDF形式でダウンロード (588K)
