It is used for the life of the elderly, which is used for medical treatment. Many medical enterprises are completely individualized in the repair of teeth and bones. 3D printing is suitable for fully individualized manufacturing and precise medical treatment. We use it to repair human body, and we have done more than 20 cases of diseases. The longest time has passed the test of 67 years.

For the development of automobile, more than 20000 parts of the car can be integrated into more than 40 parts. It will have great benefits for the weight loss of new energy vehicles. The technology is also used to make the mold of automobile tires.

For some individual consumer goods, everyone can design some jewelry and consumer goods he likes at home. We know that with the development of technology and information technology, human consumption is developing towards personalization, and the best technology to support personalized manufacturing is 3D printing. And 3D printing can build a society of innovation for all, such as you can design your own at home, and break the boundaries of the original system.

The materials used in aerospace can greatly save some materials. Many of our aerospace devices are manufactured with emission reduction, and the utilization rate is less than 5%, and now you can improve to more than 80%. Imagine that we move human manufacturing activities to space to print. Although there are many technical difficulties in 3D printing, there are many advantages. The gravity environment in space can make us use a small device to create infinite motivation, so we can use the solar energy in space and other rich energy to move large-scale manufacturing to space In order to build more living space and energy to save our environment and material constraints, we will build more living space for us on earth.

It has many technical development, such as integrating multiple materials into a part, making the surface corrosion-resistant and wear-resistant. It is high-strength inside, hollow and honeycomb in the middle, so that the material can maximize its advantages. But the scientific problem in this is the scientific problem of the structural interface of multiple materials composite materials, which is the intersection of many disciplines.
