Electron beam melting (EBM) is an additive manufacturing process that uses a focused beam of electrons to melt and fuse metal powder into solid parts. This technique operates in a vacuum environment, which prevents oxidation and contamination, allowing for high-quality metal components to be produced. During the EBM process, a computer-controlled electron beam scans the metal powder layer by layer, melting it according to a digital design. Once a layer is completed, the build platform lowers, and a new layer of powder is applied. This cycle continues until the final part is fully formed, enabling complex geometries and lightweight structures.
