Extrusion-based embedded 3D bioprinting, where bioinks and biomaterials are extruded within a support bath, has greatly expanded the achievable tissue architectures and complexity of biologic constructs that can be fabricated. However, significant scientific, engineering, and process-related challenges remain to recreate the full anatomic structure and physiologic function required for many therapeutic applications. This perspective explores the future advances in extrusion-based embedded 3D bioprinting that could address these challenges, paving the way for clinical translation of bioprinted tissues.
