New industrial chains such as design, software, materials, and digital manufacturing derived from 3D Printing technology are gradually optimizing traditional manufacturing and building a new manufacturing ecology. In our country, a wave of 3D printing “intelligent manufacturing” is covering the whole country. The application of 3D printing in various fields has been valued by people from all walks of life.

From 2017 to 2019, the scale of my country’s 3D printing industry has increased year by year, and the growth rate is slightly faster than the overall global growth rate, so that the proportion of my country’s 3D industry in the world is constantly increasing. According to the “Global and China 3D Printing Industry Data for 2019” released by CCID in March 2020, the scale of China’s 3D printing industry in 2019 was 15.75 billion yuan for the printing industry, an increase of 31.1% from 2018. In a number of application scenarios, 3D printing is becoming “connected” with protective products. For example, 3D printed ski helmets. Generally speaking, 3D printed ski helmets are made of digital technology and 3D printing intelligent manufacturing technology. The lattice structure protection system of this helmet breaks the limited protection performance of traditional helmets. In the product development process, relying on solid scientific and technological development and production technology, based on the mechanical boundary defined by nearly 10,000 head crash tests, and using cutting-edge digital algorithms, the 3D printed ski helmets that have emerged on the market have high stability and good practicability. The lattice structure protection system protects the skier’s head safety. In April 2017, Adidas announced an important partnership with Carbon to jointly produce 100,000 pairs of Future Craft 4D sports shoes with 3D printed soles. By using Carbon’s digital light synthesis technology, Adidas was able to print out shoe soles with a grid structure in 19 minutes. Because the 3D printed grid structure sole can reduce the total weight of the shoe, it can provide better stability and cushioning, so it can better respond to the movement of each athlete. Polyetheretherketone (PEEK) is widely regarded as one of the engineering thermoplastics with excellent performance, with unique high-temperature mechanical properties and chemical resistance.

Generally speaking, knee pads made of PEEK3D printing materials use magnetorheological damper, which is essentially a shock absorber in the biomechanical system, which can effectively prevent the knee from receiving more force, thereby reducing the possibility of further injury to the knee. Allow users to wear knee pads more comfortable. 3D printed goggles also have a place in practical applications. The goggles made by 3D printing rapid prototyping technology can be customized for medical staff and fit the user’s facial contours perfectly. On the whole, not only the protective effect is good, but also it is comfortable to wear, so as to prevent the wearer’s facial skin from being crushed by the goggles. Of course, being able to “make a big show” in the field of protective equipment manufacturing is inseparable from the advantages of 3D printing itself.

First of all, 3D printing technology can achieve “zero” waste of production materials in the production process. The production process of 3D printing technology is to print layer by layer according to the three-dimensional design of the parts. Compared with the traditional “subtractive” processing, it achieves “zero” waste of production materials. Secondly, the use of 3D printing technology can speed up the progress of product development. 3D printing technology has changed the way designers think, turning more ideas into reality.

In addition, the use of 3D printing technology can greatly shorten the production cycle. From design to production, 3D printing technology eliminates the process of process design and verification in the traditional processing process, shortens the production cycle, and can adjust the production quantity and batch in time according to market demand. 3D printing is regarded by all countries as one of the core technologies leading a new round of technological revolution and industrial transformation, and its development prospects are broad. With the economic development and the improvement of living standards, consumers are more pursuing personalized needs. 3D printing will work with robots, unmanned vehicles, artificial intelligence and other technologies to improve the flexibility of manufacturing production lines, and manufacture them quickly and at low cost. More types of products. As expected by industry insiders, I believe that with the rapid development of my country’s Internet of Things, new materials, cloud computing, artificial intelligence, industrial Internet, and advanced manufacturing, the 3D printing industry will achieve rapid and obvious results in localization. We wait for the arrival of this day!
