Abstract: The present disclosure relates to a system for removing an upper layer of powder from a powder bed, wherein the powder bed includes metal powder particles. The system makes use of an electrode subsystem having an electrode and a dielectric layer secured to the electrode. A metallic build plate is used for supporting the powder layer thereon.
