Abstract
An additively manufactured article is assembled from a plurality of printed voxels. The article includes a lattice of unit cells of a composite lattice material and an encasing matrix of structural material arranged between adjacent unit cells of the lattice. The structural material has greater mechanical strength than the composite lattice material.
Claims20
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 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 lattice, the 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 the consumable structural material has greater mechanical strength than the consumable lattice material.
A method of additive manufacture of an article, the method comprising:
- printing a first series of voxels of a 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;
- printing a second series of voxels of a consumable structural material in a pattern corresponding to an encasing-matrix portion of a layer of the article, wherein the consumable structural material has greater mechanical strength than the consumable lattice material;
- and
- curing the first series of voxels and the second series of voxels.
