Evaluation of compressive strength and the biophysical properties of the 3D-printed nHAP-reinforced hydrogel scaffolds. Panel (a) represents the stress–strain curve obtained from the uniaxial compression test. Panels (b–d) are obtained from compressive modulus, fracture stress, and fracture strain, respectively. Panels (e, f) represent the percentage of swelling and degradation of the synthesized cross-linked freeze-dried hydrogel-based grafts with respect to time.
