MIT Engineers Use 3D-Printed Steel to Repair Corroded Bridge

MIT engineers use 3D-printed steel to repair corroded bridge

Using a laser-based additive manufacturing technique called cold spray, the team successfully repaired a corroded section of a bridge in Great Barrington, Massachusetts, last month. The process involved accelerating particles of powdered steel in heated, compressed gas, then applying it to the damaged sections in layers.Read Entire Article

MIT researchers repair bridges by 3D printing steel onto corroded beams — Tech uses compressed gas to heat and accelerate powdered steel particles

The University of Massachusetts at Amherst worked with MIT researchers to create a cost-effective way to repair bridges and extend their lives until they can be replaced.
