3D printing technique is applied to electro-active polymer material-ionic gel. Solution configuration method is employed in hot pressing process for preparing ionic gel. The characteristic size distribution of the ionic gel core layer and electrode layer after the single line and line assembly experiments are studied under combinations of parameters such as flow rate and scanning speed. The experimental results show that the extrusion flow rate and the scanning speed influence the width of the fiber width, and then influence the single layer quality of fiber spelled surface. On the basis of the optimum process parameters and layer thickness, an ionic cylindrical ring structure with thickness of 0.5 mm is printed by multi-layers. The force of about 500 mN is applied to the measurement point of the structure, and the voltage response of 0.35 mV can generate on the upper and lower surface of the structure. The sandwich structure of ionic gels is made by composite printing technology. The printed ionic gel specimens are driven by DC voltage of 3.5 V, and 1.5 mm deformation could generate within 18 s at the end of the specimen. The sensing and driving performance test results prove that the 3D printing process of ionic gels is feasible, which lays a foundation for subsequent complex manufacturing of materials and applications in soft robots.
