3.2 3D printing of A-SA-Gel hydrogel scaffolds
The A-SA-Gel hydrogel scaffolds were fabricated by extrusion-based 3D
printing technique followed by crosslinking under the optimal conditions
as described previously. The scaffolds were printed with eight layers,
having the final size of 20 × 20 × 5 mm (L×W×H). A representative gross
view of the as-printed scaffold is presented in Figure 2C and top-angle
view of the same is shown in Figure 2D. The scaffold was printed as per
the pre-designed architecture without any deformation.
