世界最大规模3D打印混凝土步行桥在上海落成   2019-01-14

 

Over 1,400 years ago, Chinese people built the first known stone arch bridge in an epoch we do not readily think of as technological. Now, in an age when the prominence of technology cannot be denied, the glory of those bygone civil engineers has been recreated through 3D printing technology.
Two 3D-printed bridges — the world’s largest 3D-printed concrete pedestrian bridge in Baoshan District and a resin bridge in Putuo District ­— have brought technology more widely used in education, medicine and the automobile industry into architecture and construction.
The technique is much faster and cleaner than the alternatives. The bridges are both more durable and cheaper than conventional construction techniques, according to Xu Weiguo, an architecture professor with Tsinghua University, who built the Baoshan bridge.
