Thermomechanical behaviors of printed composites made up of resin matrix with water–glycerol inclusions. a) The uniaxial tensile and b) thermal expansion tests of pure resin and resin‐based composite with liquid inclusions at a volume fraction c _i = 15%. c) Thermal deflection of a printed two‐layer beam (top layer, pure resin; bottom composite layer, resin containing liquid inclusions). The dashed line shows the theoretical prediction in Equation (5) with c _i = 15%. d) Bending of two‐layer beams at different c _i from 0% to 25%. e) Thermally induced flower‐shaped complex based on the two‐layer beam structure. The beam could maintain at the flower‐shaped configuration upon fast cooling to the room temperature. Scale bars, 1 cm.
