Advancing Applications with Gradient TetraLattice Structures

1. Solid Freeform Fabrication Morphology TetraLattice MSOE • TetraLattice Intro • With the additive nature of Solid Freeform Fabrication it is possible to create structures never thought possible, such as complex, three dimensional lattice structures. TetraLattice is one of these structures. • TetraLattice is modeled after the crystalline structure found in diamond -tetrahedron- offering a simple repeating lattice unit. Arrays of TL units form complex structures as well as complex channels within objects, resulting in many useful characteristics. • Applications of TetraLattice • Based on this TetraLattice geometry -interconnected in all directions- several applications have emerged and more are anticipated. • TetraLattice has been used for metal and composite castings. TetraLattice has more applications, including: • Conformal cooling & heating systems • Micro lattices & scaffolds • Fast build style • Advanced Applications of TetraLattice • Since the inception of TetraLattice, MSOE has realized that it is possible to intertwine two of these lattice structures. The ability to intermesh two lattice structures opens many new opportunities including: • Gradient morphologies • Conformal thermal cycling • Transfer and filtering systems • Stress-reducing build style Negative or Positive CAD Representation Simple, Efficient 3D Lattice Structure Can be Intertwined for Advenced Applications Conformal Cooling Air-oil Heat Exchanger For further information, please contact: • Milwaukee School of Engineering • Rapid Prototyping Center • 1025 N.
