Three-Dimensional Printed Multiresponsive Structures of Smart Hydrogel.

ABSTRACT: Hydrogels, as soft smart materials, have been widely used in the manufacturing of responsive biomedical structures. The manufacturing process of smart hydrogels is critical for their application; however, the production efficiency and precision of the extrusion-based 3D printing method for the fabrication of responsive structures of gelatin-based hydrogels have not been extensively studied. In this study, a gelatin-based shape memory hydrogel was designed and prepared with the addition of sodium alginate, tannic acid, and sodium iron ethylene diamine tetra acetic acid to improve its mechanical strength and photothermal properties. The printability of the hydrogel based on extrusion-based 3D printing was studied under different mixture ratios of hydrogel components. The appropriate printing
