Electron Beam Melting

Electron Beam Melting (EBM) technology offers high productivity by utilizing a high-power electron beam that allows for high melting capacity of metal powder. The electron beam unit is built on state-of-the art electronics with no moving parts, which enables extremely fast and accurate beam control—allowing melting at multiple points simultaneously, contributing to faster build times and exploiting design freedom enabled by additive manufacturing.

During the EBM build process a thin layer of powder is distributed, heated and selectively melted. After melting the layer, the build table is lowered, and the sequence is repeated until the build is complete. The EBM process takes place in a vacuum, providing a clean and controlled environment and excellent thermal insulation. It is a high-temperature process, resulting in stress-free components with material properties better than cast and approaching wrought properties.
