Authorities in Dalian in northeast China's Liaoning province confirmed on Wednesday the completion of the city's largest 3D laser printer, reports the People's Daily, the mouthpiece of the Communist Party of China.
The machine is currently the world's largest 3D laser printer with a maximum processing size of 1.8 meters and was co-developed by the Dalian University of Technology and Dalian Science and Technology Development. The printer is able to produce large industrial samples as well as complex molds and encompasses unique technology called contour line scan, which reduces the processing time by 35% and manufacturing costs by 40% compared to its counterparts.
Designed and produced by professor Yao Shan and his team from Dalian University of Technology, the 3D printer is considered to be the driving force of the "Third Industrial Revolution," the paper said, adding that other countries have only been able to create small desktop 3D printers that are unable to manufacture large industrial parts in short periods of time and at a cheap rate. For this reason, the printer is a tremendous breakthrough in the 3D printing field by tackling numerous difficulties and challenges, Yao said.
He added that the new type of 3D printer is able to produce industrial parts 5-15 times faster than the current printers available around the world, and it can also copy one tonne of an industrial part for less than 1,000 yuan (US$160). The 3D printer in Dalian has already gained two national invention patents, the People's Daily said.
