Abstract: Compaction systems and methods of compacting components are provided. In one aspect, a laminate of a component can be laid up on a tool of a compaction system. The laminate defines a cavity. A noodle is positioned relative to or in the cavity. A noodle ring is then positioned relative to the noodle. For instance, the noodle ring can be placed over the noodle. A cross section of the noodle ring can be shaped complementary to a cross section of the noodle. A plunger of the compaction system is moved so that it engages the noodle ring. Particularly, the plunger is moved in such a way that a force is applied on the noodle ring so that the noodle ring compacts the noodle into the cavity.

Abstract: A system for recoating a powder bed includes a build platform holding a powder bed and an electrode assembly including an electrode and an insulating shield. A voltage supply produces a high voltage alternating current and communicates with the powder bed and the electrode. The electrode assembly is positionable over the powder bed, such that when the electrode assembly is over the powder bed, the shield is between the electrode and the powder bed's top surface. The voltage supply produces a high voltage alternating current that creates an alternating electric field between the electrode and the powder bed that causes the powder of the powder bed top surface to oscillate in a region between the shield and the bed and then reposition themselves on the bed such that the top layer of the powder bed is smoother than it was prior to when the powder particles began oscillating.
