Self‐regulating rheological properties of designed ink formulations. a) Shear‐thinning behavior of the three inks. b) Log–log plot of storage modulus (G′) and loss modulus (G″) as a function of shear stress for three ink formulations. c) Recovery measurement of Ink1‐4‐0.5, which sweeps from low stress to high stress and back to low stress. d) Schematic illustration of the typical printing settings of DIW 3D printing. Comparison of experimental data with theoretical data of Ink1‐4‐0.5 at e) different air pressure P and f) different nozzle diameter D. Data in (e,f) are means ± S.D., n = 3.
