Opening claim text (preview).
What is claimed is: 1 . A metal lattice for a carbon dioxide scrubber, comprising: a metal lattice body defining a plurality of intersecting ligaments, wherein nodes are formed at intersections of the plurality of intersecting ligaments; and wherein a node density of the metal lattice body varies. 2 . The metal lattice of claim 1 , wherein the metal lattice is formed by an additive manufacturing process comprising one of a powder bed fusion process and a directed energy deposition process. 3 . The metal lattice of claim 2 , wherein the additive manufacturing process is a laser powder bed fusion process. 4 . The metal lattice of claim 1 , wherein the metal lattice body comprises a cross-sectional profile having a first portion comprising a first node density and a second portion comprising a second node density at least partially surrounding the first portion. 5 . The metal lattice of claim 4 , wherein the first node density is different from the second node density. 6 . The metal lattice of claim 1 , wherein a thickness of each the plurality of intersecting ligaments is constant. 7 . The metal lattice of claim 1 , wherein the metal lattice is made from a metal material comprising aluminum or an aluminum alloy. 8 . The metal lattice of claim 7 , wherein the first portion defines a channel extending longitudinally through the metal lattice. 9 . The metal lattice of claim 1 , wherein a ligament thickness of the metal lattice body varies along at least one of a longitudinal direction or a transverse direction. 10 . The metal lattice of claim 1 , wherein the metal lattice body comprises a cross-sectional profile having a first portion comprising a first ligament thickness and a second portion comprising a second ligament thickness at least partially surrounding the first portion. 11 . The metal lattice of claim 10 , wherein the first ligament thickness is different from the second ligament thickness. 12 . The metal lattice of claim 11 , wherein a node density of at least one of the first portion or the second portion is constant. 13 . The metal lattice of claim 10 , wherein the first portion defines a channel extending longitudinally through the metal lattice.
