Process and printed article

A densified component comprising:

• a printed article having an external surface and at least one microfeature with an internal surface, adjacent to the internal 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 of an article material selected from the group consisting of a nickel-based superalloy, a cobalt-based superalloy, and an iron-based superalloy, and 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 coating has a coating composition other than pure nickel and is selected from the group consisting of nickel-based, cobalt-based, and iron-based materials.
