It is found that a gear with very complicated structure is composed of several irregular gears, and the gears form a heart shape as a whole. The staff of Aurora Erwo told the reporter that this heart-shaped gear set was printed by the Z-6033D printer next to it. Although the gear structure is complex, the printing assembly is quite flexible and can rotate and twist freely. The reporter's eyes turned to a black box 48 cm long, 36 m wide and 40 cm high. This is the Z-6033D printer. At this time, the machine is printing a model, and the LED screen at the lower left of the printing rack shows that the model has been completed 75%. The reporter stared at the print head of the printer and saw that the model was forming bit by bit from top to bottom. The staff of Aurora told the reporter that the consumables used in this 3D printer are PLA material, which is a new biodegradable material, made of starch raw materials from renewable plant resources (such as corn), which is very environmentally friendly.

There is almost no material loss in the printing process of this 3D printer, and the finished product of 1 kg can be printed with PLA material of 1 kg. Next to this 3D printer, there are various printed products, such as human figures, lions and puppies. All of them are lifelike, exquisite and ingenious, and people can't help but admire the magic of 3D printing technology. 3D printing constructs objects through digital technology material printers, which are often used in mold manufacturing, industrial design, jewelry, education, medical care and other fields. In recent years, with the popularization of the concept of 3D printing technology in China, many enterprises and makers have joined the wave of chasing 3D printing technology. According to the report released by the World Intellectual Property Organization in Geneva, since 2005, more than a quarter of the world's patent applications for 3D printing technology have come from China, which shows that China enterprises and scientific research departments are full of vitality in this future high-tech industry. In the future, the application of 3D printing technology will be more and more extensive.
