Figures & data
Figure 1. a) The schematics of the 4D-printing method which allows flat-constructs to be assembled and shifted with external stimuli such as magnetic field, heat, and water. b and c) Simple flowers pattern with various bilayers oriented with respect to the long axis of each petal. d-g) A 3D-printed orchid structure e) and time-lapse transformation into a more complex 3D structure stemming from swelling effects. f and g) The orchid flower could demonstrate a range of morphologies inspired by a native orchid (scale bars, 5 mm).
