Moderate absorbance and transmittance can allow for uniform curing throughout the hydrogel, while low absorbance and high transmittance may require prolonged UV exposure to achieve effective crosslinking, albeit with the risk of photodegradation. These findings highlight the importance of tailoring the optical properties of hydrogels to optimize UV curing conditions, enabling the design of photopolymerizable hydrogels with customized performance characteristics suitable for specific applications. Digital light processing (DLP) printing, a layer-by-layer photopolymerization technique using UV light, demonstrated the hydrogel's ability to achieve high-resolution constructs with precise geometries. As shown in Figure , the DLP setup includes a build plate, liquid resin reservoir, and UV light projection system that selectively cures specific areas to form intricate 3D structures. The hydrogel's compatibility with DLP printing is illustrated by its ability to produce microfluidic devices (Figure ) with internal hollow channels (~500 µm in diameter), as well as cell strainers with hexagonal wells (Figure ) that maintain structural integrity and fine detail. The successful resolution of these features is attributed to the hydrogel's fine-tuned rheological properties, which enable precise UV curing without significant resin diffusion.
