3d bioprinting is an advanced additive manufacturing methodology focused on fabricating complex biological constructs. It involves the precise layer-by-layer deposition of bio-inks, composed of living cells suspended in biomaterials, to create three-dimensional tissue or organ structures. This research field investigates the integration of biological principles with engineering techniques to enable the creation of functional living tissues with defined architecture and cellular composition, holding significant potential for applications in regenerative medicine, drug discovery, and *in vitro* disease modeling.
