Recently, good news came from the Qingdao Research Institute of Xi'an Jiaotong University in Jiaozhou, a state-level economic and technological development zone. After 5 years of successful development, the institute successfully developed high-specification spherical titanium alloy powder and successfully broke through the technology developed in Europe and the United States for many years in China blockade. In order to compete with the institute's products, some Canadian enterprises have lowered the price from RMB8,000 / kg to RMB3,000 / kg. At present, the institute has realized industrialized production with an annual output of 15 tons.
It is reported that the Institute of powder center lasted 5 years, and finally overcome difficulties to develop research and development of oxygen content below 600PPM, the specification of 80-100 spherical titanium alloy powder, the technology is currently in the leading position in the country. According to Song Xiaoping, Director of Powder Center, 3D printing technology has been widely used in manufacturing, defense and medical industries in recent years. However, the key raw material of spherical titanium alloy powder for 3D printing has been monopolized by the United States, Canada, Germany and other countries , Resulting in high cost of 3D printing technology, directly inhibiting the development of the industry. "Universities do not do research so who should do it?" Song Xiaoping said that before he went to the Institute of Xi'an Jiaotong University, vice president, to explore in this area for many years, engaged in this research is doing my part.
"The technology sounds high-end, but it's a very versatile application." Aili Li, a powder center staff member, says parts that range from aerospace to dental implants are manufactured using medical 3D printing technology The body of the jawbone, kneecap, bone fracture at the fracture of titanium screws are the application of this technology. The center lasted 5 years, under the leadership of Song Xiaoping from the research and production equipment, independent research and development of plasma rotary electrode milling system, vacuum hydrogenation system, transmission electron microscope, scanning electron microscope, vibrating screen and other advanced equipment, Successfully developed a high-standard spherical titanium alloy powder.
With technology, emboldened enough. According to reports, the center's research technology in the initial shape in July, officially started in October this year, industrial production, the current annual output can reach 15 tons. In this period of time, there has been no sound of changes in foreign markets, the first of some 3D printing companies sold to China's spherical titanium alloy powder price reached 8,000 yuan / kg, and by the Institute's technical impact, the current Some Canadian enterprises have lowered the price to 3,000 yuan / kg, in order to compete with the products of Xi'an Jiaotong University Qingdao Research Institute.
