The world’s first 3D-printed steel bridge
Thread Content
The world’s first 3D-printed steel bridge was completed in Amsterdam’s Icon. It is made of 4,500 kilograms of stainless steel, and was printed using welding torches by four robots over a period of six months.
A rough calculation of the efficiency shows that four robots, over a period of six months, can print 5 tons of material; 5/4/6/22 = 9.5 kilograms. The current efficiency is not very high
It can actually be understood as a kind of surfacing process
It’s in the early stages of use; the technology needs improvement, so low efficiency is understandable!
I agree with you; first, address the issue of whether it’s possible to do it, and then consider efficiency and practicality.
There is one issue: how should deformation be taken into account for a continuous surfacing of this length? Is it mechanical automatic adaptation? ? Is final heat treatment required?
