Abstract
A three-dimensional, biocompatible scaffold precursor composition for room-temperature printing a bio-compatible polymer/hydroxyapatite composite scaffold includes a room-temperature slurry, comprising a mixture of a sold phase that includes a mixture of tetracalcium phosphate (TTCP; Ca(PO)O) and dicalcium phosphate anhydrous (DCPA; CaHPO), and a liquid phase that includes a polymer in a solvent. The solvent may be Ethanol (EtOH) or Tetrahydrofuran (THF), and the polymer may be polyvinyl butyral (PVB), polycaprolactone (PCL), or poly lactic-co-glycolic acid (PLGA). The slurry is printed at room temperature in aqueous phosphate (NaHPO) bath, which works as hardening accelerator, forming the polymer/hydroxyapatite composite scaffold.
