The operator uses a scanner to perform 3D scanning of the cave entrance, and quickly completes the modeling after uploading the data. After loading the building 3D printing equipment, printing begins... Recently, a scene of a certain unit of Wuxi Joint Logistics Support Center using building 3D printing technology to repair and construct military facilities was eye-catching. Technological innovation is an accelerator for improving battlefield repair and construction capabilities. One step faster in emergency repairs and construction, one point more confidence in winning. ”The leader of the department introduced that in recent years, the mission and tasks of the military have been continuously expanded, and higher requirements have been put forward for the emergency repair and construction of military facilities. However, traditional construction techniques are time-consuming, which to some extent affects the quality and efficiency of task completion. To this end, they aim at the forefront of technological development, seek support from technological innovation, and constantly explore ways to use new technologies to improve the efficiency of military facility repair and construction. In order to quickly break through the bottlenecks in the support chain, the department has established a cooperation mechanism with relevant units, conducted in-depth visits and research in the front line of the task and high-tech laboratories, held multiple joint discussions with officers and soldiers, gathered intelligence to tackle key problems, conducted on-site scientific research experiments, and successfully applied building 3D printing technology to military facility repair and construction tasks. In just a few hours, the repair and disguise of the damaged cave by the 'enemy' were completed, which was unimaginable before. ”Looking at the high-tech equipment in front of them, the task officers and soldiers at the construction site were deeply moved. In the past, due to the long solidification time of ordinary concrete, building repair work often took several days and consumed a lot of manpower and resources. Nowadays, operators only need to digitally model the entire construction process and then hand it over to the equipment for automatic printing, achieving seamless operation and integrated molding. This not only significantly reduces construction time, but also greatly improves material utilization. The head of the business department of the department introduced that 3D printing of buildings uses special concrete materials, which are printed layer by layer through a digital model of a robotic arm. It has the triple advantages of fast construction, irregular shape, and practicality, as well as high compressive strength, thermal insulation, and seismic and anti-seepage properties. This technology breaks through the limitations of traditional building standardization in terms of appearance. Based on the local terrain characteristics and functional requirements, it accurately prints irregular external structures, which can not only conform to the terrain to achieve concealment and camouflage, but also meet the needs of different application scenarios through customized internal space. Security is combat effectiveness. The leaders of the department introduced that in the next step, they will continue to expand the application scope of new technologies in the field of logistics support based on the summary of previous experience, and continuously improve their practical support capabilities.
