relatively low, get chiefly used in personal DIY, education, among others. In 2014, the global sales volume amounted to approximately 100,000 units. By contrast, industrial 3D printers have wide applications and are principally marketed in the United States, Japan and Germany. Among them, the United States occupied a market share of around 40% in 2014.

At present, China's 3D printing market is still at its initial stage, with the industry chain to be improved. For example, some core components and 3D printing materials for China-made 3D printing equipment have to be imported from overseas. But 3D printing technologies in national defense and aviation industries have taken the lead in the world. In 2014, China's 3D printing market size approximated 4.65 billion. It is projected that in the following yearsthe market size will still grow at an average rate of around 40%, and that it will very likely exceed RMB20 billion by 2018.

In 2014, China's 3D printing market featured a rather low concentration degree, and the number of enterprises involved was close to 100, but mostly small-sized. The 3D printing equipment manufacturers consist mainly of Beijing Tiertime Technology Co., Ltd., Hunan Farsoon High-tech Co., Ltd., and Shining 3D.

In recent years, as the State introduced policies incentive to the development of 3D printing industry, more and more listed companies have entered the industry, a situation that helped integrate and develop China's 3D printing industry. In 2014, there were more than 10 enterprises operating 3D printing business in China, mainly including Golden Laser, Sunshine Laser & Electronics, Guangdong Silver
