Bone tissue engineering using B-tricalcium phosphate scaffolds fabricated via selective laser sintering

Abstract

β - tricalcium phosphate (β-TCP) is a biodegradable ceramic with potential application for bone replacement. In this work, porous β-TCP scaffolds were fabricated via selective laser sintering, which is a rapid prototyping technique. β-TCP and glue composite was developed as a powder material to product porous scaffolds, using this computer-controlled sintering and deposition process. The β-TCP scaffolds were produced with the strut size 800 μm and max porosity 55.4%. Compressive modulus ranged from 13MPa to 18Mpa, and shrinkage was about 26%. Analysis of the measured data shows a high correlation between the scaffold porosity and the compressive properties based on SLS process relationship. © 2006 International Federation for Information Processing.
