11. An additively manufactured article based on a plurality of printed voxels, the article comprising:
a printed and cured lattice of unit cells of a consumable lattice material, the printed and cured lattice including a first series of voxels of the consumable lattice material in a pattern corresponding to a unit-cell portion of a layer of the article, the consumable lattice material including a host material and a nanoparticle filler; and
a printed and cured encasing matrix of a consumable structural material arranged between adjacent unit cells of the printed and cured lattice, the printed and cured encasing matrix including a second series of voxels of the consumable structural material in a pattern corresponding to an encasing-matrix portion of a layer of the article, wherein a loading of the nanoparticle filler of the consumable lattice material exceeds a loading of nanoparticle filler of the consumable structural material, and wherein the consumable structural material has greater mechanical strength than the consumable lattice material.
