中国首座3d打印可伸缩桥在上海亮相

A 3D-printed retractable bridge was built in Shanghai, China. See how it can unfold itself from a cylinder.

中国上海建造了一座3d打印的可伸缩桥。看看它是如何从一个圆柱体展开来的。

这座桥被人们命名为万年轮，高度上面是1.1米，重量仅有85公斤，在整个3D打印伸缩桥上面能看到分成了九段的伸缩效果，还有桥的两侧扶手上面有三十六片，整个三角形面板的正反面有十七片的四角形面板，在整个桥面的组成和变化当中看到了整个万年轮的灵活反应

I believe only the the triangular panels are 3D printed. The structure itself mainly comprises of metal sections, perhaps aluminium, and hydraulics components. The 3D panels don't serve much except for aesthetic purpose.

我觉得，只有三角面板是3D打印的。该结构本身主要由金属部分，可能是铝，和液压元件组成。除了美学目的，3D打印的面板并没有多大用处。

The panels are very impt for children pets and wheelchairs and people with poor balance

这些面板非常适合儿童、宠物、轮椅和平衡感差的人使用

steel can be 3d printed. however this is only done for airplane parts to get different density and allow the body to be lighter. a bridge however does not require this level of weight saving.

钢铁可以3d打印。然而，这只是为了飞机部件得到不同的密度，使机身更轻。桥梁不需要这种程度的减重。

Netherlands also have build 3D printed bridge

@Oliver Sparks Well, obviously that's a conspiracy concocted by you right (since you couldn't display it). Stop making those gratuitous accusation!

显然这是你捏造的阴谋。不要再作那些无端的指责了
