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
