Formally known as ‘cold spray’, the technique sprays metal powders at high velocities to add material to existing objects. Amazingly, the speed at which the material hits the object is enough to help it adhere—there’s no high temperature or pressure required to build up layers of metal onto the object in questions. Anteneh Kebbede, from GE, explains:
“[W]hat’s particularly exciting about cold spray as an innovative, 3D process is that it affords us the opportunity to restore parts using materials that blend in and mirror the properties of the original part itself. This extends the lifespan of parts by years, or possibly by decades.”
