Zusammenfassung:	A method of additively manufacturing an object includes successively forming a plurality of powder layers by depositing powder over a build platform using a powder-deposition apparatus. The method also includes successively forming a binder shell by bonding select regions of each one of the plurality of powder layers before forming each successive one of the plurality of powder layers using a binder-delivery apparatus. The binder shell encloses a portion of the powder. The method further includes densifying the portion of the powder bound by the binder shell using a consolidation apparatus.
