An additive manufacturing system and an input material that overcomes that need to heat and extrude solidifying materials to create a three-dimensional structure. The system arranges subunits of the input material into repeating, interlinked subunits that can be arranged to manufacture a three-dimensional structure that is flexible but also has sufficient structural integrity to retain a desired shape during the additive manufacturing process or post-manufacturing usage.
