WebElectron beam melting (EBM or EB-PBF) is one PBF process massively exploited in industry and academia [10]. In this technique, electrons are generated by a tungsten filament or a lanthanum hexaboride cathode and accelerated to 60 keV. Then two electromagnetic lenses focus and deflect the beam onto the powder bed [11]. The … WebElectron Beam Melting (EBM) is a 3D manufacturing process in which a powdered metal is melted by a high-energy beam of electrons. An electron beam produces a stream of electrons that is guided by a magnetic field, melting layer upon layer of powdered metal to create an object matching the precise specifications defined by a CAD model.
