At present, 3D printing technology has become a key technology to improve the design and manufacturing capabilities of spacecraft, and its application in aerospace and aviation industry is expanding. Domestic and abroad enterprises and research institutions using 3D printing not only print the aircraft, missiles, satellites, manned spacecraft parts, but also print the engine, UAV, micro-satellite, which obtain significant benefits in terms of cost, cycle, weight and other aspects, and fully demonstrate the 3D printing technology in the field of application prospects. Compared with the traditional manufacturing methods, 3D printing technology can significantly reduce the production costs, and even make great breakthrough in the traditional manufacturing process for the complex shape of the restrictions. 3D Printing brings a revolutionary transformation of production and processing concepts to promote the global aerospace industry, and has played an important role in aerospace and aviation.

In recent years, with the advent of 3D printing technology, the problems faced by organ transplantation may be solved. 3D printing technology appeared in the mid-90s of last century, the actual use of light curing and paper stacking technology such as rapid prototyping device, is based on computer three-dimensional digital imaging technology and multi-level continuous printing of a new application technology. 3D Print Artificial Organs are a technique for printing live tissue based on live cells using 3D cells as a basis for 3D printing. Studies have shown that 3D print artificial organs can be in their own adult stem cells in vitro induced differentiation of living cells as raw materials, in vitro or in vivo direct printing of living organs or tissues, which will lose the function of the organ or tissue replacement, to some extent This solves the problem of transplant donor deficiency. Therefore, 3D print artificial organs have been in the field of organ transplantation to obtain some results in the bones, artificial blood vessels, skin, vascular splint, heart tissue and cartilage structure and other aspects of application.

Using 3D printing techniques, it is possible to create view molds in hours or days because of the rapid prototyping characteristics of 3D printing, car manufacturers can apply to the development of automotive shape plans. Compared to the traditional handmade sludge mold, 3D printing can more accurately convert the 3D plan into something, and the time is shorter, improve the level of production efficiency of the car plan. At present, many manufacturers have been in the planning aspects of the beginning of the application of 3D printing skills, such as BMW, running the middle of the plan. Car manufacturers can use 3D printing techniques to automate small batches of custom components and production, and are able to create and create complex shapes such as inorganic form factor, hollow and negative tension. 3D printing can quickly make the appearance of complex parts, when the test results, change the 3D file from the new print can be tested again.

Electronic product manufacturing in the electrical interconnection technology, has been by surface assembly technology, micro-assembly technology, three-dimensional assembly technology, high-density assembly technology and other technology as a symbol of the development period, and gradually entered the photoelectric interconnect, green assembly, structural functional components interconnection , Multi-media complex components such as interconnection technology as a symbol of the new technology development period. To ensure the quality and efficiency of the electrical interconnection of various new circuit components / modules, the electronics industry is demanding new processes and new methods that are compatible with these requirements. The 3D printing process is rapid, the complexity of structural complexity and other technical characteristics, especially for electronic products, single-piece, multi-species development of small quantities, and the use of traditional manufacturing methods difficult to achieve the development of structural electronic products.

Mold 3D printing as a new type of processing technology, greatly improving the mold production efficiency. In the mold design, production and maintenance of the three main links, can be found in 3D printing applications. Enterprises in the development of new products, you can use 3D printing technology to create samples, the traditional manufacturing technology for mass production. Because it can not only remove the traditional mold manufacturing mold, mold through the manufacture of samples, and then repeatedly modified, and finally produce a satisfactory sample steps, thus speeding up the time to market, improve economic efficiency. The use of 3D printing technology to create complex parts of the advantages of processing with a special structure of the mold, such as with the cooling channel with the mold.

Both the nuclear industry and the aerospace industry require high-quality, high-strength components. For nuclear power plants, in the manufacture of shield design before the need for on-site inspection, and a wide range of nuclear power plant distribution, each nuclear power plant required to shield the place, to the shielding design has brought great difficulties. The use of three-dimensional scanning and cloud platform design, and through the 3D printer shielding materials, small batch custom production, greatly reducing the development process and reduce costs, the design of the shielding material with the needs of parts to achieve better fit, play the best Of the nuclear radiation shielding function. In addition, three-dimensional scanning and 3D printing technology can be used to make low-level radioactive waste containers for mobile nuclear waste; the use of laser direct manufacturing system to produce nuclear reactor prototype; through selective laser melting technology to print fuel components.

With the gradual maturity of 3D printing technology, for each individual production of a product is becoming a reality, with the help of 3D printing technology, we can not only in the details of the product to be adjusted. At present, more and more people are interested in 3D customization, in the fashion design, entertainment industry, jewelry customization, architectural models, apparel and other industries have a lot of practice.
