Cold Spray Additive Manufacturing (CSAM) is a solid-state metal 3D printing process that builds parts by accelerating metal powders at supersonic speeds toward a substrate using a high-pressure gas jet. Unlike traditional additive manufacturing methods, Cold Spray doesn’t use heat to melt materials. Instead, the particles deform on impact and bond together, producing high-strength, corrosion-resistant parts with minimal distortion. This heat-free approach preserves the mechanical integrity and microstructure of the original material.
