Given that 3D printing technology is not mature enough in terms of the variety, cost and materials of printable products, large-scale commercial applications have not yet been ushered in. However, it is undeniable that 3D printing will be the benchmark technology for creating a new round of industrial revolution. The promotion of policies will make the industry more exciting, and its market size is expected to be constantly refreshed. The overall scale continues to grow. According to data from the US consulting firm Wohlers Associates, the global 3D printing market in 2011 was 1.71 billion US dollars, of which consumer products and electronics accounted for 20.3%, the automotive sector accounted for 19.5%, and the medical and dental sectors accounted for 15.1%. In 2012, the scale of 3D printing industry increased by 25% compared with the previous year, reaching US$2.14 billion. In 2013, it reached US$5.12 billion, with a growth rate of 239%. The growth rate is very alarming. It is expected to reach US$12 billion in 2014 and 50 billion in 2018. Dollar. At present, the largest market in the United States and Europe and the United States, the fastest growing emerging countries are Russia, India, South Korea, Brazil, Japan, China, other countries are gradually increasing, the global market is growing rapidly.
A favorable factor driving the rapid expansion of the 3D printing market is the widespread use of 3D technology in manufacturing, the reduction in printing costs, and the growth in applications in new markets. 3D printers are currently divided into industrial and desktop models. The industrial type is subdivided into two parts. One is prototype manufacturing, in order to quickly output three-dimensional models that are difficult to be completed by hand or mechanical tools, and the other is that large-scale metal structural parts are directly manufactured, and they have already begun to appear in the automotive, aerospace and other industrial fields. Industrial 3D printers range in price from $20,000 to millions of dollars and are more expensive. 3D printing is also widely used in the field of industrial products, and it has a wide application space in the medical field. Vendors have noted the growing demand for 3D printers in the medical field, beginning with product development in the medical field and developing advanced materials for a variety of complex medical applications such as transplant surgery and tissue implant engineering.
