"If a worker wants to do his job well, he must first sharpen his tools." The pursuit of weapon equipment performance has a long history. The emergence of information-based and intelligent warfare has put forward higher requirements for the development and use of weapons and equipment. In some military conflicts in recent years, it has become a reality to provide artillery tail wings and dropping devices in real time with the help of 3D printing technology. These components produced by this technology can be matched with UAVs for use, effectively improving the strike speed, and also make the military color of 3D printing technology richer to a certain extent. As with weapons and equipment, so does the development of ammunition. Recently, a news from the UK showed the 3D printing explosive technology to the world more clearly - a laboratory sponsored by the British Ministry of Defense successfully developed the 3D printing explosive technology. As we all know, the strike power of ammunition comes not only from the explosive itself, but also from the "shape" of the explosive after "shaping" and the specific configuration of the container containing the explosive. "Shaped" explosives and containers are different in shape, height, thickness, and energy released in a certain direction. Based on this, 3D printing explosive technology came into being. Its essence is to use this technology to design specific explosive shapes to obtain different damage effects. According to foreign media, the 3D printing explosive technology of this "exposure" originates from the future explosive project launched by the British Ministry of Defense in 2015. This technology aims to develop a high-performance professional printer, further improve the corresponding material extrusion scheme, so that the limited charge can obtain more effective destructive force. Compared with the United Kingdom, the United States started earlier in the application of 3D printing explosive technology. The United States began to research related technologies in 1999, and later used this technology to print personalized customized explosives. It has accumulated some technology in single nozzle printing, modulation of explosive formula, and control of explosive energy release. A series of performance parameters, such as compressive strength, energy distribution range and destructive force of explosives, are compared by computer, and the optimal solution of "input" and "output" is calculated. Then, the personalized explosives are prepared by using a program controlled printer. This method can not only make the explosive "shaping" or shell forming at one time, but also reduce the cost. Because of unmanned operation throughout the process, the safety of staff is effectively guaranteed, so more countries pay attention to it. Australia announced US $2.6 million for research on this technology over the next two years. Some countries have also decided to cooperate in the development of this technology. 3D printing explosive technology is just one of the methods and ways to enable ammunition by means of high-tech means. It can be predicted that with the new technology pushing the door of "empowering weapons and ammunition" wider, the research, development and use of traditional weapons and ammunition may face more changes.
