3.1 Rheological Testing of A-SA-Gel hydrogel
Viscoelasticity is one of the key features that determines the ability of a biomaterial to be suitable for 3D printing application. The viscoelastic properties of the A-SA-Gel hydrogel are shown in Figure 2A, which represents its shear thinning behavior. The results of steady-shear rate sweeps are plotted in Figure 2B, which shows higher storage modulus and lower loss modulus of the crosslinked hydrogel. It is one of the highly required behaviors of any biomaterial to be 3D printed into various structures with high fidelity.
