Manufacturing Space Homogeneity in Additive Manufacturing – Electron Beam Melting Case
Strojniški vestnik - Journal of Mechanical Engineering, 2017 This paper focuses on the manufacturing space homogeneity of the electron beam melting (EBM) technology. An Arcam AB A1 machine is used as tool for experimentations, with titanium (Ti-6Al-4V) as material. The objective of this study is to show the correlation between workpieces geometrical deformations and their position in the manufacturing space ...

Powder bed charging during electron-beam additive manufacturing [PDF]
Acta Materialia, 2017 Abstract Electrons injected into the build envelope during powder bed electron-beam additive manufacturing can accumulate on the irradiated particles and cause them to repel each other. Under certain conditions, these electrostatic forces can grow so large that they drive the particles out of the build envelope in a process known as “smoking”. In the
