3D printed bridge rails.

Zijinshan/Jinling Evening News (Reporter Yu Fei) Jiangsu's first bridge "printed" by 3D technology was held in Nanjing yesterday morning. All completed by a private enterprise in Nanjing.

On the Fengyuan Road Bridge in Kuah Community, Xiongzhou Street, Liuhe, the reporter saw that the brand-new bridge rails were very strong. Li Jin, chairman of Nanjing Jiayi Precision Machinery Manufacturing Co., Ltd., told reporters that if the bridge was reconstructed according to traditional technology, the cost would be more than 150,000 yuan, and the construction period would be at least one month. The construction cost is only 50,000-60,000 yuan, and it only takes 10 days from processing to installation.

In the company's production workshop, the reporter found that 3D technology has also produced houses, tables, decorations, etc. In a workshop, the master worker threw the mixed raw materials into the machine, and the mechanical equipment was like making a cake, layer by layer, The prototype was soon completed. According to reports, there are currently no more than 3 enterprises that can use this technology to produce in the country. "If you have been using foreign technology and equipment, the price must be high, but we are all independent research and development and have patents, from design to production, installation is our own technology." Li Jin said.

Earlier, some 3D buildings reported by foreign media were found to be "fragile" after testing, or they could only be viewed from a distance. However, the railings of this bridge in Nanjing have been identified by strength tests, which are 2-3 times that of traditional cement-cast bridge railings, reaching 60 MPa.

Liu Zijie, president of Nanjing Xinghua Architectural Design and Research Institute, told reporters that 3D architecture is currently in its infancy in my country. In addition to the benefits of cost savings, this technology is also in line with the future development direction of the country's green environmental protection and unmanned construction. This model project The "first landing" in Jiangsu will play a very important role. The reporter learned at the scene that such 3D technology will also be used in the construction of the southern new city.
