Extrusion-based bioprinting is a 3D printing technique that involves the controlled deposition of bioinks, which are materials composed of living cells and biomaterials, to create three-dimensional structures. This method utilizes a nozzle to extrude the bioink in precise patterns, allowing for the fabrication of complex tissue-like structures with desired shapes and functionalities. The ability to print living cells in a layer-by-layer fashion is crucial for applications in tissue engineering and regenerative medicine.
