  • SHAPE-SHIFTING STRUCTURED LATTICE AND METHOD OF MAKING A SHAPE-SHIFTING STRUCTURED LATTICE
    Publication number: 20200130261
    Abstract: A shape-shifting structured lattice comprises a printed lattice including printed ribs joined at nodes. Each printed rib has a predetermined sweep angle {tilde over (?)}i between adjacent nodes and a bilayer structure including at least two printed filaments in contact along a length thereof. The at least two printed filaments comprise different linear coefficients of thermal expansion and/or different values of elastic modulus. When exposed to a stimulus, the printed lattice adopts a predetermined three-dimensional geometry.
