What is the maximum printing size of domestic 3D printers?

A new 3D laser printer developed by Dalian University of Technology and Dalian Youlike Technology Development Co., Ltd. has a processing size of1.8 *1.8 *1.8 m, which has set a new world record for the processing size of 3D printers. The working principle of this 3D printer of Dalian University of Technology adopts "contour scanning" technology. Compared with the traditional laser 3D printer, the processing time is shortened by 35% and the manufacturing cost is reduced by 40%. In addition, in the field of 3D printing, the aircraft parts manufactured by AVIC with 3D printing technology have reached 4*3*2 meters.
