| 20120285114 | Manufacture of Lattice Truss Structures from Monolithic Materials - Methods and systems to manufacture lattice-based sandwich structures from monolithic material eliminate the bonding process which is conventionally used to join lattice-based truss cores to facesheets to form sandwich structures.
