19 Claims

1. A densified component comprising:

a printed article having an external surface and at least one microfeature with an internal surface adjacent to the external surface, the internal surface of the at least one microfeature including a non-line-of-sight surface relative to the external surface, the at least one microfeature being an additively manufactured feature with a predetermined structure and the printed article being formed by additive manufacture with a porosity such that the printed article is not at full density, the porosity including surface-connected porosity at the external surface and at the internal surface; and

a metallic microlayer coating the external surface of the printed article and the internal surface of the at least one microfeature, including coating the non-line-of-sight surface of the at least one microfeature, to seal the surface-connected porosity of the printed article by overlaying the surface-connected porosity along the external surface and the internal surface,

wherein the metallic microlayer is formed of a material other than pure nickel.
