Abstract: Extrusion- grounded 3D bioprinting (eclipse) critically depends on the parcels of hydrogels, which serve as bioinks. These accoutrements must combine precise rheological geste, mechanical strength, and cytocompatibility to support complex towel structures. This paper investigates a range of hydrogel phrasings natural, synthetic, and mongrel — through mechanical, rheological, and natural lenses. Our findings emphasize a “rheological window” pivotal for printability and identify gelatin- alginate and MeHA hydrogels as high- performing campaigners. The study also highlights the eventuality of stimulants- responsive hydrogels and AI- guided design as arising inventions in biofabrication.
