Plate perforated micron, 3D printed hip

Fraunhofer Advanced Technology Innovation and Exhibition Center of Germany officially unveiled this month in Nanjing Future Technology City, which aims to bring Fraunhofer application research promotion to Chinese companies through German technology to empower Chinese companies' public technology platforms. The association's many advanced manufacturing technologies. Yesterday, the reporter visited the Innovation and Exhibition Center.

2.5 hours "print" out of the human hip joint

In the exhibition hall of the Innovation and Exhibition Center, a number of advanced products made in Germany are displayed. Among them, a hip cup with a diameter of only about 5 cm has attracted the interest of visitors. Innovation and Exhibition Center Operator - CEO of Nanjing Ruide Zengyu 3D Technology Development Co., Ltd. said that this hip cup is printed in 3D, each takes 2.5 hours compared to the average hip joint. The cup is printed directly using titanium alloy after the CT scan data. The special hole-like structure allows the muscle tissue to grow into it, which is truly suitable for the human body.

Not only titanium alloys can be printed, but also special materials such as copper and tungsten can be printed. "At present, domestic technology has not solved the problem of 3D printing of copper materials, and Germany has used green laser technology to effectively solve the problem of melting and adding materials for copper materials."

The reporter was informed that the Innovation and Exhibition Center currently exhibits advanced technologies and exhibits from the Institute of Laser Technology (ILT) and the Institute of Manufacturing Technology (IPT) in the five research institutes of the Fraunhofer Institute, covering light and surface. Technology, production and intelligent manufacturing technologies. These technologies are used in industrial manufacturing to solve high-end manufacturing, precision control, precision machining and other fields.

It is difficult to distinguish the steel plate with micro-holes.

256 micropores are distributed on a stainless steel sheet with a length of about 10 cm, which can be clearly seen through a microscope. The high-precision optical assembly platform, which is not small, can provide assembly solutions for miniature camera lenses and micro-optical components. In the laboratory of the Fraunhofer Advanced Technology Innovation and Exhibition Center in Germany, a number of high-end technologies in the field of intelligent manufacturing have been put on the ground.

"The hole diameter is only 50 microns, and the diameter of a person's hair is usually 0.2 mm, which means that 4 holes can pass through a single hair." The commemorative hand held a stainless steel sheet to explain to reporters that the technology was made by Flau. The "Rotating Optical HDO Integrated DOE System" developed by the Enkhov Laser Technology Institute (ILT) can be applied to the production of a key component of the Hall electric propulsion system in the aerospace field - the micro flow controller.

In addition, the laboratory's high-precision optical assembly platform is also eye-catching. "Don't look at the machine so big, its operating parts go only 10 nanometers away from each other, and 3,000 steps is equivalent to crossing a hair strand." Commemorative said that the manual adjustment method will lead to unstable product quality, and this The system platform can be moved, aligned and bonded with fully automatic precision components. It can be used to mount mobile phone lenses, precision mechanical parts, etc. It is especially suitable for demanding optical systems. It is currently in micro optical components and wafer level optical devices. Get applied on.

German technology empowers Chinese companies

German manufacturing is one of the most competitive manufacturing industries in the world and has a leading position in the global manufacturing equipment sector. The Fraunhofer Institute for Applied Research Promotion is the largest applied technology research institute in Europe. The association has 72 research institutes and has about 25,000 R&D personnel. 2017 Thomson Reuters released the list of the world's 25 most innovative government research institutions, the US Department of Health and Human Services, the French Atomic Energy Commission and the German Fraunhofer Association ranked the top three in this list.

In order to strengthen the connection with Germany's "Industry 4.0" and promote the upgrading and upgrading of traditional industrial technology, Nanjing Future Science and Technology City, together with Nanjing Reid Zengyu, and the German Fraunhofer Research and Research Promotion Association, jointly created the advanced technology innovation of Fraunhofer, Germany. And the exhibition center.

The Fraunhofer Advanced Technology Innovation and Exhibition Center in Germany is positioned as the Fraunhofer Association's first internationalized, public-serving, public-service intelligent manufacturing industrialization service platform in China. In commemoration, the Fraunhofer Advanced Technology Innovation and Exhibition Center currently provides customized research and development services for Chinese companies, especially those in the Yangtze River Delta, in addition to custom processing of personalized products. “In Germany, a large number of SMEs are unable to afford R&D costs, and they will adopt this R&D outsourcing or purchase technology to master the latest cutting-edge technologies.”

In the future, the Fraunhofer Advanced Technology Innovation and Exhibition Center will also introduce German technology to incubate in Nanjing Jiangning. “The Innovation and Exhibition Center will be built in three phases, and the first phase has been put into operation.” The memorial said that the second and third phases of the project will introduce four to five Fraunhofer Institutes and their incubators. The advanced technology and technology of the prospects, as well as the Chinese supporting enterprises, enable the public technology service platform to empower Chinese enterprises.
