3D printing industry begins to boom

But the industry has a way to go in China.

"Some people have a misunderstanding about 3D printing technology," said Luo Jun, executive chairman of the Chinese 3D industry alliance. "The technology is not omnipotent. Not all products can be printed out by a 3D printer. And not all things printed can be put into practical use."

3D cannot replace traditional manufacturing, but can supplement it, he added. The technology can save costs and shorten time in the industrial design field.

Last August, researchers at an east China university printed out a kidney the size of a knuckle. The tiny kidney consisted of living cells and hydrogel. Hydrogel contains agar and sodium alginate, providing cells with a stable growing environment.

China lags behind other countries in the research and development of 3D printers for industrial or biological use.

"Our advantage is that 3D printing has attracted attention and participation of domestic enterprises," said Luo. China is at an important period of upgrading traditional industries, which provides opportunities for 3D printing technology, he added.

3D printing is limited in its application market and materials, said Luo. "It still has a long way to go."
