Pretty sure that printing a 2D or 3D model that is responsive to external changes is not a new thing; recall a material that takes two forms based on an electri

  "Novel method" doesn't mean something similar has never been done, it means it has never been done this way. By aligning cellulose fibrils during printing, the hydrogel composite ink is encoded with anisotropic swelling and stiffness, which can be patterned to produce intricate shape changes. The anisotropic nature of the cellulose fibrils gives rise to varied directional properties that can be predicted and controlled.
