Additive Manufacturing of Metallic Parts with Electron Beam Melting (EBM)


Electron beam melting (EBM) is a type of additive manufacturing technologies. EBM uses electron beam as an energy source to melt metal powder and produce metal thin layers. This sequence is repeated in a layer-by-layer manner to fabricate three-dimensional (3D) components.
This technology can produce any kinds of structures based on 3D CAD models and is suitable for custom-made manufacturing.
In addition, our recent studies revealed that the unique microstructure, such as directional solidification and uniform dispersions of fine precipitates, are obtained by EBM; this technology is useful to realize advanced materials that cannot be obtained conventional manufacturing.

Targeted Application(s)/Industry

The EBM technology has received much attention for producing metal parts used in biomedical, aerospace and automotive industries.
Rapid prototyping / rapid tooling is one of the applications of this technology.
