You may remember the mask-making machine used by Agent Ethan in the movie "Mission Impossible 4". This magical prop can make a mask that looks exactly like others in a short time, using 3D printing technology. However, Cong Zhen, vice president of Jingwei China, recently encountered a headache for him: many home-sponsored projects seeking investment called themselves "3D printing", but in the past, they did something very different. thing. "It's hard to put it in the IT hardware category or the Internet category at once, but to be honest, there is still a big gap from the concept of the new type of hardware based on intelligent systems that I originally envisioned." Cong Zhen is right in Nandu The reporter was so emotional. Nevertheless, the domestic public opinion about the 3D printing industry policy has been increasing day by day. It is reported that following the high-level position of the Ministry of Industry and Information Technology in December last year that will promote the industrialization of 3D printing, relevant persons from the Ministry of Science and Technology have also recently indicated that 3D printing-related strategic planning is being studied and formulated and is expected to be announced after the two sessions. Affected by this, last Friday, individual stocks such as Hongchang Electronics, Nanfeng Co., Ltd., and AVIC Heavy Machinery gained momentum. However, in the eyes of most domestic VCs, the golden opportunity to invest in 3D printing has not yet arrived. This is because the technology and market of 3D printing itself are immature. Cong Zhen ’s concern is that “If you are simply selling hardware, in the Chinese market environment, profits will be quickly diluted as competitors continue to squeeze in. E-books Is the best example. " Old technology jumps into fashion season 3D printing, scientific name rapid prototyping technology. Contrary to this fresh-sounding name, 3D printing technology has actually existed for more than two decades. The world's first 3D printer was born in 1986 and was invented by American Charles Hull. The 3D System s company he founded is already a public company listed on the NASDAQ and has become one of the leading giants in the US 3D printing industry. Since this is not a new technology, why did it suddenly become popular until now? Luo Jun, CEO of the Asian Manufacturing Association, told Nandu that he had recommended the "rapid manufacturing technology" and equipment of the rapid manufacturing center of Huazhong University of Science and Technology to member companies in 2010, but the response at the time was not enthusiastic. Looking back now, he believes that it is mainly because the external environment is still immature, and the change of traditional manufacturing production methods also requires a long-term process. Xia Qing is one of the leaders of Shanghai Zhiwei Robot Co., Ltd. The company's main business is to operate a professional forum D FR obot related to robots and open source hardware technology. He told Nandu reporter that he has been paying attention to 3D printing since a long time ago. I really saw the entity about two years ago. Someone brought back a akerbot from abroad, and Xia Qing fell in love with 3D printing at first sight. Therefore, he dedicated a piece of open source hardware on D FR obot to do research and development on 3D printing technology and 3D printers. After a period of research, experiment and development, a desktop 3D printer was pre-sold on the D FR obot website. According to Xia Qing, according to the messages on Weibo and some data on the website, it can be seen that many people have a high degree of interest in 3D printers, and some people have already booked 3D printers on their websites. But Xia Qing also confessed to Nandu reporters that the desktop 3D printer pre-sold by D FR obot uses a relatively inexpensive and low-end 3D printing technology "melt extrusion technology" and can only support the printing of plastic materials , And medical and industrial grade 3D printers are not the same. According to Xia Qing's introduction, medical and industrial-grade 3D printers can be widely used in dental, artificial joint manufacturing, aerospace and other fields due to their higher accuracy and ability to print metal and polymer materials. The Nandu reporter also further learned that at present, there are already laboratories that have successfully printed out food, blood vessels and human organs. While 3D printing technology has triggered more ethical and legal discussions, "husband, print a piece of fresh meat before work and take it home" will no longer be a dream. Material restraint 3D printing However, as Xia Qing said, although they are all called 3D printing technology, the development space and trajectory faced by the current 3D printing technology applicable to the low-end civilian market and the medical and industrial grade 3D printing technology are very different. This is also an important reason why many domestic VCs believe that the golden time to invest in 3D printing technology has not yet arrived-"the market prospect of the former is unknown, while the latter still needs a longer time to wait for technology research and development." Luo Jun revealed to reporters in Nandu that in the field of biomedicine, although 3D printing has a huge market and the technology is also very mature, it is restricted by biological materials; while industrial-grade 3D printing applications can be divided into prototype manufacturing and Metal products are directly manufactured. Prototype manufacturing technology is relatively mature and widely used, and the direct manufacturing of metal products, especially the direct manufacturing of large metal structural parts, is the core difficulty of 3D printing technology. Although this market will not be particularly large, it has high added value and the highest technological content. On the other hand, Luo Jun also pointed out that the key to restricting the development of domestic 3D printing technology is not the technology itself, but the material. At present, the materials that can be used in 3D printing include film, resin, paraffin, gypsum, nylon wire, titanium alloy, ceramics and so on. Therefore, as far as the current market situation is concerned, companies such as Mingzhan Technology, Taier Times, and Vistek, which are manufactured in original form and directly manufactured by small metal products, will go further on the road of 3D printer manufacturing and commercial sales. Farther. Taking Vistek as an example, according to Zhong Lian, vice president of Shenzhen Venture Capital, the investor of its parent company Guanghua Weiye, told reporters in Nandu that Guanghua Weiye originally focused on producing environmentally friendly plastic materials. In 2008, Guanghua Weiye successively received several foreign orders, requesting the production of some 1.75 mm diameter plastic strips. Since then, this business has expanded rapidly, and it took only a few months to become a major business of the company. Yang Yihu, the founder of Guanghua Albert, discovered at this time that these plastic strips were actually the raw materials needed for 3D printing. As a result, he brought in special 3D printing open source technical documents for research, and separately established Vistech to manufacture and sell 3D printers. In 2012, the company's domestic sales of 3D printers reached thousands, and the whole machine business for foreign markets has just begun. Yang Yihu cited one of the most typical examples to explain to Nandu reporters that Vistek's target customer, namely ZTE Mobile, uses 3D printers to make mobile phone "hands." "Shouban" is the initial model of the mobile phone, and the designer will modify it after getting it. In the traditional production method, the production of the Shouban is generally done by a special Shouban factory. It is completely handmade, which takes about two weeks and costs more than 3,000 yuan. If you use 3D printing, it only takes 3-4 hours, and the cost is only tens of yuan. In the planning of Yang Yihu, Guanghua Weiye and Vistek will focus on the production of 3D printing materials and the production and sales of 3D three-dimensional modeling software and 3D printers, respectively, to form a complete industrial chain layout for the 3D printing industry.
