Abstract: A powder bed deposition apparatus comprises a movable build plate, a powder delivery system, an energy beam apparatus capable of selectively steering at least one focused energy beam over successive quantities of metal powder, a non-metallic barrier layer, and an anchor removably secured to the build plate. The non-metallic barrier layer is disposed over a metal upper surface of the build plate. The anchor has a metal bonding surface flush with the non-metallic barrier layer, the non-metallic barrier layer and the anchor defining a removable build assembly with a powder bed working surface.
