A report on the development of 3D printing is expected to receive the central government's green light and funding support, a move that will encourage more small and medium-sized companies to enter the promising industry.

Modern manufacturing features mass production and standardization but it has faced an increasing challenge to satisfy more individual requirements from clients since the start of the 21st century. Therefore, demand for tailor-made products makes 3D printing possible, said Lu.
"Three years ago, we spent about 1 million yuan ($160,000) in developing two models to make the outer shell of a car within three months. Similar development using traditional methods requires more than one year and will cost tens of millions of yuan from making the initial model to manufacturing in bulk," said Lu.
However, Lu also noted such production cannot completely replace traditional manufacturing, especially for products that need to be made in large amounts and feature a high degree of similarity.
In the eyes of Wim Michiels, executive vice-president at Materialise NV, 3D printing is better for the environment in that there is no need to set up a full production line, which can involve a lengthy amount of time, high costs and the possible failure of the first sample due to imperfect accuracy.
"3D printing is faster and you can bring your products to the market ahead of your rivals. In addition, you have no limitations in design with this technology," Michiels said.
Although theoretically 3D printing technology can print anything from a house to a car, it needs time to test the products before they can become practical in daily life, said Lin of Tsinghua University.
"After more than a decade's research into 3D printing, people are gradually beginning to accept this new manufacturing concept. Of the two main opposing opinions, one has doubts about the production technology while the other has excessively high expectations," said Lu of Xi'an Jiaotong University.
He added that both opinions are biased. "3D printing technology is consistently improving. It just needs more research and development to make it possible to print objects using various materials. It is also worth noting there is no technology that can do absolutely anything," Lu said.
Many Chinese enterprises are keeping a close eye on the market potential for 3D printing and have started to develop their own printers. Beijing Tiertime Technology Co is one such example. The company has so far sold several thousand sets to the United States, but only several hundreds in the Chinese market.
"Our company has nearly 20 years of history. Our products for home use are priced at 9,999 yuan, while those for industrial applications are sold at 100,000 to 300,000 yuan a set," said Lin Yuting, an employee with Tiertime's marketing department.
Tiertime's Lin said most of their orders come from overseas markets including Europe and the US.
