SLS에 의한 PCL/TCP 복합체 제작공정변수의 최적화

초록

This article investigates the fabrication of polycaprolactone (PCL) composites filled with different volume fractions (10-30%) of tricalcium phosphate (TCP) by selective laser sintering (SLS) for tissue engineering scaffolds. Optimal processing parameters for each composition were developed by design of experiments (DOE). Specimens for compressive testing for each composition were fabricated and tested. The results showed that the compressive modulus increases as a function of TCP volume fraction. The experimentally measured compressive moduli were compared with moduli predicted by Halpin’s theoretical model and were found to be in excellent agreement. This result proved that experimentally determined processing parameters for each composition were well optimized.
