Abstract

Abstract β-tricalcium phosphate (β-TCP) and polycaprolactone (PCL) composites were manufactured using the lab-made 3D bioprinting system to produce 50TCP50PCL (50% β-TCP with 50% PCL) and 70TCP30PCL (70% β-TCP with 30% PCL) composite scaffolds for bone tissue engineering. The 70TCP30PCL scaffold containing the highest β-TCP content exhibited rougher morphologies and more porous than the other scaffolds ( i.e. , PCL and 50TCP50PCL). In vitro studies revealed that cell proliferation and alkaline phosphate activity were improved on the β-TCP-based composite scaffolds. Our results suggest that our 3-D printed β-TCP-containing PCL scaffolds would benefit new dental applications or regeneration therapies.
