15. An additive manufacturing system, comprising:
an energy source configured to provide an energy beam for at least one of fusing at least a portion of a material added to a surface of a substrate for forming a cladding layer on the substrate or heating the cladding layer; and
a forging device comprising a forging head configured for reciprocating movement up and down along a trajectory in a vertical direction to contact and forge the cladding layer during formation of the cladding layer by additive manufacturing; and
a forging head fixing device comprising a cavity that receives the forging head,
wherein the forging head comprises a base portion, a forging portion, and a through hole extending in the vertical direction formed through the base portion and the forging portion, and
wherein the through hole and the cavity are aligned with each other to allow at least one of the energy beam or an additive material to pass through during formation of the cladding layer.
