A couple weeks ago we covered Shanghai Construction Group’s gigantic 3D printer printing the world’s largest plastic 3D print in the form of a pedestrian bridge. After 35 days of printing, the bridge is finally complete.

At a staggering 15.25 meters long, 3.8 meters wide, and 1.2 meters high, the bridge required a 3D printer so large that technicians worked inside of it during operation. After the addition of a clear floor to show off the internal infill, the bridge will be placed over a waterway in a park in Taopu Smart City, a hub of innovation.

By using glass fiber-infused ASA (acrylonitrile styrene acrylate) to print the bridge, it’ll be able to support up to four people per square meter. And at 5,300kg, it’s also the heaviest plastic object to be 3D printed. It’s expected that the bridge will last 30 years. Check back soon for an update on its final installation.
