There was a milestone in 3D printing in 2013, when GE used 3D printing technology to make more than 85000 jet engine fuel nozzles for its latest aircraft. Unlike traditional methods, they no longer need to assemble 20 different parts, but are integrated with a 3D printer.
In 2016, a 400-square-meter two-story villa was unveiled in the industrial zone of Songzhuang Town, Tongzhou District, Beijing. the walls of the entire villa were printed using 3D printing technology and took only 45 days to complete.
3D printing technology, known as the new technology leading the third industrial revolution, has attracted much attention in recent years. It not only leads the science and technology industry to a new direction, but also brings new development opportunities for the education industry. It is reported that 3D printers were installed in primary and secondary schools in almost major cities in China in 2016. How is the application of 3D printing education in China? What are the shackles and solutions? What is the development and profitability of 3D printing listed companies? What is the development trend in the future?
I. 3D printing technology research factional distribution map
As the guide of high-end manufacturing technology, 3D printing has attracted much attention in the industry. the research time of 3D printing technology in China is basically synchronized with that of the world. at present, several units carrying out 3D printing research have their own characteristics.
Tsinghua University carried out the research on 3D printing technology earlier in China, mainly in the field of electron beam selective melting technology, and developed related 3D printing equipment. Beihang has developed a complete set of engineering equipment for laser rapid prototyping of aircraft large integral titanium alloy main load-bearing structures.
Northwest Polytechnic University established the laser rapid prototyping system and carried out process experiments for many kinds of metal materials; Huazhong University of Science and Technology studied the 3D printing of metal materials and polymer materials; Xi'an Jiaotong University carried out work on 3D printing of biomedical internals and laser melt deposition of metal materials, and completed a number of clinical cases of personalized repair of 3D printing in orthopaedics.
The relationship between domestic well-known 3D printing enterprises and universities, and the related situation of 3D printing industry is shown in Table 1.
Second, the educational layout of the 3D printing company
According to the survey, the major foreign 3D printing listed companies were in a state of loss or small profit in 2015, and the same is true of the major domestic 3D printing listed companies. It is reported that the listing location of foreign 3D printing companies is mainly on NASDAQ, including Faro, Materialise Nv, Exone Co, Stratasys,3D printing giant 3D Systems chose the listing location in the New York Stock Exchange. Among these foreign 3D printing listed companies, Faro and SLM Solutions are in a state of small profit, other listed companies are in a state of loss, and the degree of Stratasys loss is relatively high.
Relatively speaking, there are few listed companies in the domestic 3D printing industry, including Xianlin 3D, Fenghua Zhuoli, Liantai Technology and Jiayi Hi-Tech. Most of the domestic 3D printing companies choose the listing location on the new third board. In the domestic 3D printing listed companies, Liantai Technology, Xianlin 3D and Fenghua Zhuoli are in a profitable state, while the other listed companies are in a state of loss.
3D printing listed companies have great expectations for education. one of the three major business layouts of 3D is to start with the business model of 3D printing innovative classroom and 3D printing innovative medical examination center in the field of educational creative consumption. combined with 3D data cloud platform (3D guest network), it can be copied and promoted quickly through online and offline, on-campus and off-campus. Stimulate the enthusiasm and interest of students, families and consumers to 3D printing products. Combined with education, it has become one of the breakthroughs in the 3D printing industry.
"to invest in education is to invest in future clients." First, Zhao Donglai, deputy general manager of 3D, said. Beijing Everbright has been working in the field of 3D technology for nearly 10 years, and has launched 3DCloud photo modeling service platform, 3D printer and other products. But Beijing Everbright does not stop at the 3D industry, but combines it with youth education, introduces the concept of steam education, develops a series of related courses and builds Qiaoku 3D + think-tank, and sends the latest technology to young people in a way that combines education with fun.
Jiayi Hi-Tech invested in the establishment of Wuhan Jiayi 3D Education Technology Co., Ltd., committed to the application of 3D technology in education and teaching, and provide the overall solution of 3D education and teaching.
The pursuit of 3D printing education in the capital market. In October 2015, the 3D printing platform Monkey Network received 10 million-level A round financing from Taiyue Indus, a subsidiary of Taiyue, China. In the early days, the Monkey Network team mainly provided 3D printing services for professional users. in order to meet the different requirements of professional users from various industries for size, material and precision, the Monkey Network team accumulated many 3D printers of different specifications and formed a printing network.
Edou Technology is the first company in the world to focus on 3D printer applications, and it is also the first company in the world to develop application software for 3D printers. On November 25, 2015, the preschool 3D printing education program provider, edou Technology crowdfunding, completed 14.47 million of the excess financing. This is an equity crowdfunding launched by edou Technology in JD.com Finance. The final investment is only 7.092 million yuan. The pre-investment valuation of this round of edou technology is 32 million yuan.
In February 2016, the "3D + Chuangkui" project successfully obtained angel round financing with a valuation of up to 40 million yuan, which attracted great attention from the 3D community and the entrepreneurial industry.
Third, 3D printing education investment case.
3D printing technology can realize the organic combination of virtual world and physical world, combine touch and vision, grasp the three-dimensional model of core concepts through students' sense of touch, and make boring courses vivid. The combination of 3D printing and teaching does not lie in its technology, but as a tool, the original abstract can be printed into concrete objects through 3D printing.
The school-based curriculum for 3D printing will also continue to be developed, but the focus will still be on design. 3D printing has become a necessary carrier of the curriculum, just like computers, integrating the education system of primary and secondary schools.
Case 1: 3D Printing Innovation Laboratory of the Chinese Academy of Sciences
Zheng Yiqian, head of Zhongxinghua Education, said that the "3D Printing Innovation Laboratory" is supported by the high-performance 3D printing system of the Guangzhou Institute of Electronic Technology of the Chinese Academy of Sciences, and under the theoretical guidance of the General Research Group of "creativity in Primary and Middle Schools" of the Ministry of Education. Integrate the training and certification content resources of the national information technology shortage talent training project of the Ministry of Industry and Information Technology, and horizontally unite the China creativity Competition and the selection Committee of "Zhong Nanshan Innovation Award". Form a set of "innovative campus" overall solution with equal emphasis on theory and practice and common interests and achievements.
It is reported that the schools that jointly built the "3D Printing Innovation Laboratory" with the Guangzhou Institute of Electronic Technology of the Chinese Academy of Sciences have spread across 15 provinces across the country. The next step will continue to build bridges between primary and secondary schools, Guangzhou Institute of Electronics of the Chinese Academy of Sciences and Peking University, integrate 3D printing technology with primary and secondary school disciplines, and guide and encourage various co-building schools to build 3D printing school-based courses based on local characteristics and local culture.
Case 2: creator education
On March 3, 2016, the Educational equipment Research and Development Center of the Ministry of Education formulated the main points of work for 2016 according to the work plan of the Ministry of Education, and regarded creator education and the "STEAM curriculum" as the central work of strengthening education research on innovation and creativity. Among them, 3D printing technology, which is increasingly known by people, has become an important bridge for the realization and promotion of creator education.
At present, 3D printer has been introduced into some primary and secondary schools and university scientific research institutions, especially in the field of basic education. In addition, some business models of 3D printing education have emerged, which enrich the application of 3D printing in the field of education. Creator education under the service of 3D printing technology is in line with the learning nature of students, promote students to cooperate in collective learning, achieve the integration of multi-disciplinary knowledge, and turn creativity into physical objects, which will also be the development direction of the future education model.
Case 3 Education and training of 3D printing
At the end of 2016, 3D Printing Vocational training School was listed in Qingdao. It is a training base for the China 3D Printing Technology Industry Alliance and the World 3D Printing Industry Alliance to alleviate the shortage of 3D printing talents. At the same time, business models of 3D printing education have also begun to emerge in China, including the Devil Monkey Network invested in Taiyue, China, which focuses on teacher training. "3D printing rich case examples are especially suitable for the case-based way of vocational education," Zhang Yong, CEO of Monkey Network, told Blue Whale Education. "3D printing itself has advantages in this area, first, there are a lot of data, second, there are many cases, and third, we can bring real first-line operations to the school."
Other innovative models include idreamer3D for 3D printing education for teenagers and children, D National School, an online interactive platform for 3D printing based on social networks, Teach Innovation Campus launched by Hangzhou Mingzhan in conjunction with Zhejiang University, and Manheng Digital's "3D Interactive Teaching system" for colleges and universities.
IV. Industry bottlenecks to be broken
Domestic enterprises involved in 3D printing are still in the stage of extensive production equipment, lack of core leading enterprises, and more importantly, domestic 3D printing enterprises have some problems, such as production efficiency, material shortage, lack of core technology and so on.
"it is impossible to commercialize mass production, which is also the most criticized point in the industry." To investigate the reason, industry experts revealed that, on the one hand, the consumables used for 3D printing are very limited. At present, there are only more than 10 kinds of raw materials for 3D printing, such as gypsum, inorganic powder, photosensitive resin, plastics, ceramics and so on, and the price is more expensive, especially metal. On the other hand, the price of 3D printers is very high, most desktop-level 3D printers sell for about 20, 000 yuan, and domestic imitations cost about 6000 yuan, but the quality is difficult to guarantee.
"there are two bottlenecks in 3D printing in education, one is the lack of teachers. The second is the lack of supervisors who really understand the 3D printing project. " Yang Dehong of the 3D Printing Innovation Laboratory of the Chinese Academy of Sciences told Blue Whale Education that "3D printing projects without substantial results will eventually be eliminated."
V. Prospect of 3D printing education: the outbreak is imminent.
3D printing education has bottlenecks, but the momentum of development is unstoppable. According to the latest survey, the global revenue of the 3D printing industry rose from $1.714 billion in 2011 to $5.165 billion in 2015, maintaining a compound growth rate of 30 per cent from 2011 to 2015. In 2016, the 3D printing industry still maintained a trend of rapid development. A report from the forward-looking Industrial Research Institute predicts that the global 3D printing market will reach 35.4 billion US dollars by 2020.
In the field of emerging technology, 3D printing has gone through the stage of hype and is rapidly integrating into people's production and life. As a high-quality educational resource and a new form of educational information, 3D education will create a new teaching model, which is the development trend of education in the future.
The promotion of 3D printing to education is not one-way, on the other hand, the penetration into the field of education can promote the evolution of 3D printing technology. Whether it is the promotion of 3D printing to education or the back-feeding of education to 3D industry, 3D printing presents strong vitality and great development prospects, which are all exciting.
