  Abstract

In this study, the rheological properties, output characteristics, and mechanical properties of hydrogel mixed with κ-carrageenan and Laponite-XLS were quantitatively analyzed according to 3D printing process conditions. The 3D printing device was designed and manufactured as a pressure-type device with temperature control for stable transport and precise layering of hydrogel. The printing quality map was obtained according to printing conditions (nozzle temperature, pressure, nozzle movement speed, etc.) and it was confirmed that stable printing was possible under optimal printing conditions. The stability was confirmed through a tensile test on the joints between the printed fibers, and Dog-bone-shaped specimens were manufactured under printing direction (parallel, tilted) and infill density (30%, 50%) conditions and tensile tests were performed. As a result, the tensile strength tended to significantly increase as the printing direction was aligned with the tensile load and the infill density increased. As a result, it was confirmed that the κ-carrageenan/Laponite-XLS composite hydrogel has sufficient potential as materials that satisfies structural precision, rheological controllability, and mechanical stability when combined with 3D printing technology.
