Electron beam melting process: A general overview

Electron beam powder-bed fusion (EB-PBF) is the most commonly named electron beam melting (EBM) process. Unlike the other additive manufacturing (AM) for metal components, EBM is today applied for mass production in aerospace and medical because of the high temperature and the possibility to nest parts easily. The aim of this chapter is to provide a general overview that will be helpful to understand the EBM process and the physical phenomena that occur during the EBM process. It majorly covers introduction, mechanism, process parameters, and applications of EBM process; features of EBM parts and influence of process parameters on them. Lastly, the chapter covers in-situ monitoring system and simulation tools for EBM process.
