At the end of 2018, a 15.25-meter-long, 3.8-meter-wide and 1.2-meter-high milky-white 3d printing bridge was put into use in Shanghai's Taopu Zhichuangcheng Park, making Shanghai one of the first cities in China to introduce 3D printing bridges. 

      Three years later, an updated version of the 3D printed bridge is back in Shanghai. It is reported that the bridge is located in the northern area of Shanghai's Zhangmiao Street jurisdiction, Wen Zaobang along the shoreline of the old transport terminal No. 1 innovation with Transport Wisdom Bay Science and Innovation Park, and three years ago, the bridge is the same 3-d printed, but three years ago the 3D printed bridge was a fixed bridge, three years later the 3D printed bridge was a retractable bridge. In addition, Xiao Bian learned that the bridge is called "Ten Thousand Years Ring" , the bridge 9.34 meters long, 1.5 meters wide, 1.1 meters high, 850 kilograms in weight, divided into nine sections of telescopic segment. There are 36 triangular panels on both sides of the handrail and 17 quadrilateral panels on both sides of the bridge. The bridge's opening state can be controlled via the phone's Bluetooth, pressing a button and opening it in just one minute for people to use. The bridge can carry up to 20 people at a time and is equipped with an automatic gravity warning system. When it comes to 3D printing, it has been used more and more in architecture since the twenty-one th century, and there are many 3d printed buildings around the world, including villas, libraries, toilets, bridges, landscapes and so on. The development and popularization of 3D printing can not be separated from linear motor, which is introduced into 3d printing equipment as a driving device for its high speed and high precision. 

      The Linear Motors developed by Kunshan include the U-SHAPED slot without iron core and the flat plate with iron core, which are applied in the fields of architecture, industry, semiconductor, biomedicine, aerospace and so on.
