Metal 3D printing, also known as metal additive manufacturing, is a process of creating three-dimensional metal parts by fusing layers of metal powder together with a high-power laser or electron beam. The process can be used to create components with complex geometries, intricate features, and functional performance that cannot be achieved with traditional metal manufacturing techniques. The metal powder used in this process can be a variety of metals, from aluminum to titanium and stainless steel. This technology has revolutionized the metal manufacturing industry, allowing for faster, more efficient production and a reduction in waste and cost.
