At present, the 3 d printing is still in its early stages of development. With the increase of material manufacturing technology development is the most leading there are some difference between the United States.
In the popularization of 3 d printing in China further industrialization problems can be summarized as the following. First, it is not for 3 d printing industry in China to establish unified common standards. Due to the use of 3 d printing products for the characteristics of small batch, individuation, it highlights common standards of decisive significance. And the whole industry is still in a domestic integration degree is low, more disordered phase. This greatly restricted the 3 d printing in the domestic large-scale commercial process; Second, 3 d printing supply of raw materials has become the one of the barriers in the development of our country. Due to the particularity of increasing material manufacturing technology, consumables has played a decisive role in the whole manufacturing process. And 3 d printing consumables in China mainly rely on foreign imports, especially metal materials. High cost of materials may become hinder the development of one of the reasons; Domestic machinery manufacturing industry chain is relatively mature, low cost of traditional manufacturing, will reduce the price of the 3 d printing. To some extent weaken the market the importance of this technology.

Although at present, the 3 d printing in the way of the industrialization of slightly lags behind other developed countries, but in the increase of material manufacturing technology research and development, our country is not inferior to other countries, even in some areas is a world leader. Especially in the use of selective laser sintering (SLS) technology manufacturing large parts of this technique, is walking in the 3 d printing technology development in our country is the most mature before the United States, leading the world.
Hua-ming wang, a professor at the research team, led by relying on "the plane titanium alloy large complex integral component of laser forming technology" for "2012 annual national technological invention award". The second paragraph of this technology has been successfully applied in our country independently design and manufacture of domestic large aircraft C919 components manufacturing. Only 55 days can be in the lab, create the C919 head four main windshield window frame. If custom to foreign company, it should be at least two years' time, and cost will also increase many. And print out by technology of titanium alloy parts is likely to large-scale application in China's fourth generation fighter. Visible, the 3 d printing in the domestic market development space will be very large.
Yu-sheng shi research team led by professor is China's earlier 3 d printing technology achievements of the team. In 2001 with the selective laser sintering (SLS) technology, won the national scientific and technological progress second prize. Based on laser sintering of powder bed stereo, and with "print" technology, won the second prize of national technological invention in 2011. Its team 1.2 m by 1.2 m working face of the world's largest "stereo" printer selected member of both the selection of news ", "2011 China top ten science and technology progress

Many domestic enterprises is also committed to the r&d and manufacture of 3 d printing devices. Domestic sales such as shaanxi hengtong developed in 1997 and the first light curing rapid prototyping machines, and now the company has introduced price less than 7000 yuan of personal 3 d printers; Beijing lung source in the company set up in those days was successfully developed China's first SLS technology of rapid prototyping equipment; Surplus at the photoelectric in 2007 successfully developed the first domestic direct manufacturing of laser sintering molding plastic parts 3 d printing system.

The development of 3 d printing industry nature also cannot leave the government's strong support. National leaders to 3 d printing to major national science and technology project proposal made important instructions. Ministry of science and technology will be 3 d printed into the national high technology research and development program (863 program) ", "national science and technology support plan manufacturing 2014 annual project options guide. Not only that, the local government in 2013, also put forward to support the development of 3 d printing all the planning and policy. The next government will further introduce more positive in 3 d printing industry development policy. As a representative of the "third industrial revolution" technology, 3 d printing will get more attention from the outside.
