4D Printing Technology: Magic Material Or Automatic Deformation

< p > it is reported that some researchers of < a href= "http://www.91se91.com/news/index_c.asp" > US < /a > are developing a technology of "4D printing", which will enable large 3D print parts to be assembled in accordance with preset structure and appearance mode. The emergence of this technology will likely revolutionized the traditional manufacturing industry in the future, making it easier to make manufacturing under harsh environmental conditions. < /p >
< p > > a href= "http://www.91se91.com/news/index_c.asp" > 4D printing technology < /a > involves the application of special materials. These materials will change their shape when they perceive the state of motion, temperature change or exposure to water, air, gravity field and magnetic field. The fourth dimension refers to the "self-assembly behavior" of materials. 4D printing is essentially the use of composite materials for 3D printing, through this way to add a function, that is, deformation. < /p >
< p > the researchers showed the samples of composite material printed by technology < a href= "http://www.91se91.com/news/index_c.asp" > 3D printing technology < /a > on the spot. The sample can be transformed into "M-I-T" after touching water. This property is added to the material body. Researchers use a special Autodesk software to simulate and optimize how and when the material is deformed. For example, we can use this software to design nano scale self-assembly system, and also to design large scale self-assembly system at human level. < /p >
< p > 4D printing technology is not yet mature, but researchers at Massachusetts Institute of Technology's self assembly laboratory believe that this technology will eventually bring about revolutionary changes in bioscience, materials science, software, robotics, manufacturing, transportation, infrastructure construction, art and even space exploration. < /p >

< p > the Kuiwei regional Federation of trade unions held the regional textile workers' professional skills competition in Weifang thousand Ye color spinning Co., Ltd., and officially opened the curtain of the activities of vocational skills in the whole region. < /p >
< p > in order to enhance the comparability and feasibility of the competition, it objectively shows the technical level of textile workers, and decides to take the spinning process as a competition item through consultation between the regional Federation of trade unions and the participating enterprises. < /p >
< p > eight o'clock in the morning, skills competition began formally in a tense and orderly atmosphere. Weifang thousand industry color spinning Co., Ltd. and Weifang port Feng Textile Co., Ltd. and other contestants came up with their own skills. With dexterous hands and intelligence, they completed the drafting, twisting and winding forming tasks, skillful operation skills and intense competition consciousness to bring the atmosphere to a climax. < /p >
< p > finally, the participants from Weifang thousand Ye color spinning Co., Ltd. performed well and won the first prize of the competition with superb skills. After the competition, the heads of the textile companies expressed their approval to the regional Federation of trade unions to organize this kind of competition. They were determined to make innovations in the next stage of production and development, perfect technical problems and promote the company's leaping development. < /p >
