上海机械施工Group Co(SMCC），一家中国建筑公司，以及Polymaker，是3D打印灯丝制造商，已与3D打印在上海的行人桥合作。
The bridge will be installed in theTaopu Smart City, Putuo District.The陶浦聪明城市是由一家德国建筑公司设计的HPP Architekten，覆盖西北上海地区4.2平方公里。
3D printed architectural feats
Even though a lot of applications of 3D printing are in the manufacturing sector, such as parts for automotive and aerospace, the technology has also shown architectural potential. Currently,NASAis exploring a火星可持续栖息地使用自动3D打印机制造雷电竞app下载。在地球上，今年7月，一个法国家庭搬进了3D印刷房屋。Currently, a Dutch robotic and AM companyMX3D正在研究3D印刷钢桥in Amsterdam, something the company has done before.
在中国也汤吉大学铺设了两个3D印刷桥in Shanghai, but only as a model.
But the latest Shanghai project, the motivation behind constructing a 3D printed bridge is urban renewal. According to HPP the idea behind Taopu Smart City is creating a “compact energy-saving city”, as Taopu is among the three heavily polluted areas in Shanghai.
3D打印的桥梁是无污染结构和使用“智能”技术的演示。
3D打印桥
桥的总重量为5800公斤，长15.25米，宽3.8米。负责此建筑本身的3D打印机是猛mm象。它的构建体积为24米长，宽度为4米，高1.5米。
The bridge was printed using丙烯腈苯乙烯丙烯酸酯(ASA), a robust plastic. ASA is resistant to heat and water, therefore, is an ideal choice for a structure meeting various weather conditions. For the bridge, the ASA was mixed with glass fibers to add strength.
After testing the bridge for endurance, the Deputy Chief Engineer of SMCC,Chen Xiaoming，说，“这座桥的负载为每平方米250千克，这意味着至少有四个成年人可以同时行走。”
桥以一部分打印，需要30天和5个小时。最后一块将安装在陶浦中央绿带,part of the Taopu Smart City.The陶浦中央绿带预计将于2020年向公众开放。
