3D printers are filled with different "printing materials" such as metal, ceramics, plastics and sand, which are real raw materials. After the printer is connected to the computer, the "printed materials" can be superimposed layer by layer through computer control, and finally the blueprint on the computer becomes a physical object. Generally speaking, a 3D printer is a device that can "print" real 3D objects, such as robots, toy cars, various models and even food.

For the forefront of bio-manufacturing of 3D printing, Yan Yongnian believes that the three-dimensional controllable assembly process of cells based on 3D printing technology is the core technology in bio-manufacturing, and its goal is the formation and manufacture of life with metabolic characteristics.

Not long ago, domestic scientists used 3D printing technology to construct a biological scaffold, and installed new ears for five children born with ear defects by taking out chondrocytes from their ears.

3D printing is a basic technology, which can be widely used in many fields after being integrated with other technologies. People's understanding of 3D printing has changed from concept stage to application stage, which shows that the development of 3D printing industry is just around the corner.

The future development trend of 3D printing is higher speed, higher precision, lower cost, wider application and simpler operation, and its development direction is end product production, intelligence and mass production.
