Assessment of artificial bone materials with different structural pore sizes obtained from 3D printed polycaprolactone/-tricalcium phosphate (3D PCL/-TCP).

Artificial bone is the alternative candidate for the bone defect treatment under the circumstance that there exits enormous challenge to remedy the bone defect caused by attributes like trauma and tumors. However, the impact of pore size discrepancy for regulating new bone generation is still ambiguous. Using direct 3D printing technology, customized 3D polycaprolactone/-tricalcium phosphate (PCL/-TCP) artificial bones with different structural pore sizes (1.
