3D printing using cellulose nanomaterials is explored as a processing route for developing materials for different functional applications due to the inherent shear thinning property of nanocellulose aqueous gels . We have recently shown that the remarkable mechanical, chemical and biological properties, and the possibility to support living cells delivers tremendous possibilities for developing nanocellulose based medical implants and scaffolds via 3D printing. For eg. nanocellulose based porous hydrogel scaffold was successfully 3D printed to have gradient porosity / density and cellulose nanocrystal orientation in the pore walls which favors cartilage tissue regeneration. The biocompatibility and cartilage regeneration potential of these scaffolds with osteoblast cells was further enhanced by coating the printed scaffolds with dopamine and growth factors as Fibroblast growth factor (FGF-18). Nanocellulose can also act as template for in situ processing of hybrids with metallic organic frameworks or hydroxyapatite which generates 3D printable inks for hierarchically porous multi-functional materials for targeted drug release and tissue regeneration. Nanocellulose gel based 3D printing thus provides a flexible and green platform for producing a variety of functional materials for biomedical implants, environmental remediation, wearable electronics, etc.<br/><br/>
