Ink formulations comprising bioactive particles, methods of printing the inks into three-dimensional (3D) structures, and methods of making the inks are provided. Also provided are objects, such as tissue growth scaffolds and artificial bone, made from the inks, methods of forming the objects using 3D printing techniques, and method for growing tissue on the tissue growth scaffolds. The inks comprise a plurality of bioactive ceramic particles, a biocompatible polymer binder, optionally at least one bioactive factor, and a solvent. |
