On April 19th, during a practical drill, the 40th Group Army’s engineering team, the bridge and bridge, had just started an emergency military road operation and encountered an accident. "The stone was caught in the fan and the water tank was leaked." At the emergency, the repaired four-level sergeant Wang Yuming arrived with a 3D printer . I saw at the scene: Yuming rapid measurement tank "wound", then quickly made three-dimensional model based on data ......, 3D printing, machine "spit" out of a square plug. He grinded the stopper a little, and it blocked the leak of the tank tightly and the excavator was put back into operation. The 3D printer entered the military field and was inspired by Wang Yuming's innovative thinking. In recent years, on the exercise field, the group often has the shackles of "a broken part affects an exercise." As the backbone of the maintenance, Wang Yuming saw the news of using the 3D printer to make human organ models on TV. He couldn't help but think of Lenovo: Can you introduce a 3D printer, and “destroy the printing 啥†on the exercise field to improve the efficiency of equipment repair under field conditions? After listening to Wang Yuming's thoughts, the head of the team Li Ying was very supportive. He immediately found the equipment department personnel to demonstrate, and immediately bought a 3D printer and applied it to the battlefield equipment repair practice. "The 3D printer seems to be simple, and the learning is not small." Li said that the 3D printer encountered a series of encounters at the beginning of the military. At first, due to the unskilled operation of the software, it takes several hours to make a complex three-dimensional model; the choice of materials is difficult to master, often due to insufficient performance such as hardness and toughness, the parts that have been produced have just been replaced and broken. After more than three months of groping, the group learned the technology of making various parts using 3D printers. Officers and soldiers measure 3D printed parts Wang Yuming told the author that in order to improve the production speed of the three-dimensional model of the parts, they built a three-dimensional model database of eight types of more than 150 parts including gears and reels. With this database, you can print directly when you make a component by simply calling up the corresponding model data. "The production of parts can be durable, the choice of raw materials is particularly critical." Wang Yuming told reporters that this 3D printer uses polylactic acid plastic and a variety of composite polylactic acid plastics with iron, aluminum, copper and other metal elements, according to zero The strength requirements of the components select the raw materials. In order to ensure accurate material selection, they listed the parts of dozens of engineering equipment in the whole group, and repeatedly tested and demonstrated the materials required and the proportion of metal powder added. In this exercise, the 3D printer has been used six times in succession, greatly improving the efficiency of field repair. The leaders of the regiment said that 3D printing technology is used in equipment repair, and there are still many areas to explore. Next, they plan to explore the use of resin, metal and other materials to print high-precision complex parts, making this technology more widely used in equipment maintenance. .
