Abstract: A directed energy deposition (DED) additive manufacturing system may be utilized for manufacturing a cylindrical component from a feedstock material. The DED additive manufacturing system may comprise a rotary build table, a deposition assembly for depositing melted feedstock to form the component upon rotation of the build table, and a compression rig positioned proximate the deposition assembly and operable to continuously apply a compressive load to deposited melted feedstock material during deposition of the melted feedstock material.

Abstract: An additive manufacturing system for producing a component includes a deposition assembly having a deposition head through which melted feedstock material is deposited, and a compression rig comprising a compression head supporting an inside roller, an outside roller opposing the inside roller, and a top roller, the inside roller applying a compressive load onto an interior side surface of the component, the outside roller applying a compressive load onto an exterior side surface of the component, and the top roller applying a compressive load onto a top surface of the component.

Abstract: A directed energy deposition additive manufacturing system may include an apparatus for applying a compressive load to a component being built in the system with an overhanging geometry. The apparatus has a compression head that applies the compressive load. The apparatus may apply the compressive load at a compression angle that may be complementary to an inclination angle of the component. The apparatus may operate in multiple degrees of freedom.
