Electron beam melting (EBM)

Electron beam melting (EBM)

Electron beam melting (EBM) is one of the additive manufacturing processes. In this process, a generated electron beam fuses a layer of metal powder under vacuum (to prevent oxidation). After fusion, a new layer of powder is applied, which is also fused. This process is repeated until the desired workpiece is completely created.

After the workpiece has been created, it must be freed from powder residues and any supporting elements. Further post-treatment may also require surface finishing or heating to reduce residual stress. Separated powder can be reintroduced into the process to create further workpieces.

Prerequisites for use

Know-how in the application

A certain amount of know-how is necessary for the use of additive manufacturing processes. This includes the areas of design, material selection and manufacturing.

Make-or-buy decision

On the market, numerous providers offer their services in the field of EBM. These have the relevant expertise and the necessary machines. Therefore, the purchase of EDM services or the in-house production of workpieces must be weighed up.
