Abstract

A new potential biomimetic polymeric 3D scaffold is fabricated using collagen entrapment and 3D printed polylactic acid scaffold. The modified scaffold was characterized by compressive modulus, degree of swelling, water contact angle (WCA), and Fourier Transform Infrared Spectroscopy (FTIR). The findings show that sample PLA/col40 with 40s entrapment duration is the optimum composition that meets the requirement for artificial bone tissue replacement. In vitro biomineralization using simulated body fluid (SBF) demonstrates that the PLA/collagen 3D scaffold is able to promote the growth of hydroxyapatite (HA) after 7days which will subsequently improve the osteoconductive and osteoinductive properties of the 3D scaffold. The overall results suggest the potential of the 3D PLA/collagen scaffold as a prospective material for bone tissue engineering applications.
