Systems and methods provide for forming layered structures. Textured tapes may be fabricated, having cast and/or embossed patterns that provide for desired flow characteristics in an assembly of stacked, rolled, and/or otherwise assembled tapes. In some cases, shear thinning materials may be formed into textured tapes using localized shear stress to induce shear thinning during a pattern formation. A pattern may be maintained after removal of the shear force due to the high viscosity of the material at low shear stress.
