img-tetralattice-photos2With the additive nature of Solid Freeform Fabrication it is possible to create objects never thought possible, such as complex, three dimensional lattice structures. TetraLattice is one of these structures.

TetraLattice is modeled after the atomic bond structure found in diamond offering a simple repeating unit-cell. Arrays of TL units form complex lattice structures as well as complex channels within objects, resulting in many useful applications.
