3D printed steel bridge for walking.

According to Mark Girolami from Cambridge University,¨that investigations into bridge failures often reveal deterioration that was missed. Constant data feedback may have been able to prevent these failures by providing an early warning, he says.

Girolami says that early indications for the strength of 3D-printed steel are positive. One of the things that we found is that the strength characteristics are dependent on the orientation of the printing. But what was in some sense surprising was that the baseline strength was what you would expect of just rolled steel, and it actually increased in some directions.¨
