Direct‐write assembly of a three‐ dimensional periodic structure comprised of hexagonal filaments is demonstated. The structure is created by robotically depositing a concentrated colloidal gel‐based ink through a cylindrical deposition nozzle modified by attaching a UV‐LIGA (lithography, electroplating, and molding)‐fabricated hexagonal micro (μ)‐tip that controls filament geometry.
