Abstract

A powder bed fusion additive manufacturing system (100') includes a build powder bed (106') positioned on a build plate (108') in a build chamber (110'), an energy source scanning system (115') configured to scan an energy source (116') across a top layer (118') of the build powder bed (106') to consolidate selected portions of the top layer (118') to build a single layer of a desired part (120'), a build piston (112') configured to adjust the height of the build plate (108') after the layer of the desired part (120') is built, and a fresh build powder distributor (126') configured to distribute a layer fresh build powder (104') over a build powder bed (106') such that the layer of fresh build powder (104') is level and smooth. The fresh build powder distributor (126') comprises a distributor excitation device (126a') configured to cause the fresh build powder distributor (126') to vibrate at a predetermined vibrational frequency while distributing the layer of fresh build powder (104') over the build powder bed (106').
