Assessment of robustness and elasticity of Alg/HAT/dAECM multicomponent vascular constructs. A) Compression strength graph comparing the stiffness of single‐component and multi‐component hydrogels. Macroscopic demonstration of compressibility showed that Alg hydrogels are more resistant to compression than the visco‐elastic Alg/HAT/dAECM multicomponent hydrogels. B) Tensile strength curves of Alg and Alg/HAT/dAECM hydrogels (2 × 4 cm). While pure Alg‐based hydrogels were fractured under low stress values and below 5% strain value, Alg/HAT/dAECM multicomponent hydrogels remained intact up to 30% strain, confirming the elastic property of the vascular constructs. C) Tensile strength for 3D printed vascular constructs; can withstand up to 120% strain value. D) Cyclic tensile graphs for Alg and Alg/HAT/dAECM hydrogels further demonstrated the strength of Alg/HAT/dAECM against repetitive deformation. E) Dynamic amplitude measurements supported the elasticity and ability of Alg/HAT/dAECM multicomponent constructs to self‐recover from high shear force.
