In addition to tensile strength, further physico-mechanical properties of hydrogels must meet specific demands to ensure cytocompatibility, which include fast hydrogel formation, a matrix stiffness matching to the target tissue, a sufficiently high hydration degree for fast nutrient diffusion, and structural robustness in physiological environments. Hence, crosslinking time, shear moduli and swelling behavior of photocrosslinked GelMA/bPE hydrogels were studied for different compositions and solvents (Figure ). Despite the slight turbidity of GelMA/bPE inks (Figure ), we did not observe any adverse effects on crosslinking time or penetration depth. Curing tests revealed no significant differences between crosslinking times of GelMA and GelMA/DbPE films of varying thickness (Figure ).
