To investigate the water uptake behavior of the samples, the mass swell ratio was examined. Cylindrical disc-shaped hydrogels with dimensions of 16 mm × 5 mm were prepared following the previously described procedure. Immediately after photo-polymerization, the mass of the hydrogel constructs was measured. Subsequently, the hydrogel samples were placed in a well plate and submerged in MilliQ water before being incubated at 37°C overnight. This allowed the samples to absorb water and reach equilibrium swelling. After removing the samples from the water, any excess moisture was gently blotted using Kimwipes, and the swollen weight of the hydrogel samples was determined. Next, the samples were placed in a -80°C freezer overnight to facilitate freeze drying. The samples were then subjected to lyophilization at -50°C for 24 h, followed by the measurement of their dry weight.
