Hydrogels have emerged as pivotal materials in biomedical applications, particularly in the realms of bioprinting and tissue engineering. These hydrophilic polymer networks can retain substantial amounts of water while maintaining structural integrity, closely mimicking natural tissues' extracellular matrix (ECM). Their biocompatibility, high water content, and capacity to encapsulate cells and bioactive agents make them ideal candidates for creating biomimetic tissue constructs. However, the diverse mechanical and functional requirements of various tissues necessitate the development of hydrogels with tunable properties. Gelatin, a denatured form of collagen, is widely used in hydrogel formulations due to its biocompatibility and cell adhesion properties. Methacrylation of gelatin (MG), also widely known as GelMA , makes it photo-crosslinkable, enabling stable hydrogel formation under UV light in the presence of a photoinitiator. This characteristic makes methacrylated gelatin (GelMA) particularly suitable for advanced bio-fabrication techniques like digital light processing (DLP) and extrusion-based 3D printing, where cross-linking control is crucial. Yet, single-component hydrogels often lack the mechanical robustness required for loadbearing applications or long-term stability. To address this limitation, the incorporation of microparticles into hydrogels has emerged as a promising strategy for enhancing these properties without compromising biocompatibility. In this study, we introduce a composite hydrogel system that incorporates precrosslinked porcine gelatin microparticles within a methacrylated fish gelatin (MFG) matrix. This hybrid approach was specifically chosen to address the physical property differences between porcine and fish gelatins, with direct implications for 3D printing performance. Notably, porcine skin gelatin possesses a higher gel strength and gelation temperature than fish gelatin, causing it to solidify rapidly at room temperature. Such behavior presents significant challenges for 3D printing, which requires materials to be in a fluid or semi-fluid state to enable precise deposition and shaping. If porcine skin gelatin were directly mixed with fish gelatin, the composite would rapidly increase in viscosity and could even solidify at room temperature, resulting in a material unsuitable for DLP and extrusion printing. By pre-crosslinking the porcine gelatin into microparticles and subsequently dispersing them in a methacrylated fish gelatin matrix, we achieve a composite hydrogel that retains fluidity until UV cross-linking. This structure provides essential shear-thinning behavior and stability suitable for various 3D printing modalities, including embedded printing, a technique in which bioinks are extruded into a support bath to construct intricate tissue structures. Embedded printing has gained considerable traction as a method for achieving detailed, multilayered designs that require additional support during fabrication. Our microparticlereinforced hydrogels demonstrate the essential characteristics for this application, with the mechanical and rheological properties necessary to act as support baths.
