Abstract

Electron beam melting (EBM) is a powder-bed fusion metal additive manufacturing technique that produces fully dense and complex parts directly from a computer aided design (CAD) model and was originally developed by Arcam AB. Unique to this additive manufacturing method, the Arcam EBM systems use a high powered electron beam to selectively melt powder to build a part layer-by-layer. The EBM technology is of particular interest to the aerospace [1], biomedical [2], and automotive [3] industries for its ability to create highly complex parts with high resolution and low lead times with goals of increasing efficiency and reducing part counts. According to Arcam, the EBMsystemis capable of processing a variety of alloys including Inconel 718, Cobalt-Chrome, and Ti-6Al-4V. The majority of research is devoted to Ti-6Al-4V.
