FIG. 4.

Effect of temperature on slurry printability and postprinting integrity. (A) Top: appearance of 3D printed honeycomb construct after removal of support slurry. Middle: the same shape printed in gelatin slurry that was transiently heated to 30°C and then cooled back to room temperature. Bottom: the same experiment using agarose slurry. (B) Top: two helixes printed in agarose and gelatin slurries. Middle: when placed in cell culture incubator for 1 h at 37°C, gelatin slurry melts, releasing the helixes. 3D, three-dimensional.
