Abstract: The present invention relates to preparation of bioink composed of cellulose nanofibril hydrogel with native or synthetic Calcium containing particles. The concentration of the calcium containing particles can be between 1% and 40% w/v. Such bioink can be 3D Bioprinted with or without human or animal cells. Coaxial needle can be used where cellulose nanofibril hydrogel filled with Calcium particles can be used as shell and another hydrogel based bioink mixed with cells can be used as core or opposite. Such 3D Bioprinted constructs exhibit high porosity due to shear thinning properties of cellulose nanofibrils which provides excellent printing fidelity. They also have excellent mechanical properties and are easily handled as large constructs for patient-specific bone cavities which need to be repaired. The porosity promotes vascularization which is crucial for oxygen and nutrient supply. The porosity also makes it possible for further recruitment of cells which accelerate bone healing process.
