A team from the Research Center for Nano-Biomaterials at Sichuan University worked on four groups of scaffolds, namely: PCL, PCL/PVAc, PCL/HA and PCL/PVAc/HA. By 3D Printing them on 3D Bioprinter V2.0 (manufactured by Hangzhou Regenovo Biotechnology Co., Ltd, China), they revealed that although they had almost similar porosity, the mechanical properties were different. PCL/PVAc/HA scaffold was selected the winner with more favorable characteristics during in vitro cell culture experiment and in vivo bone formation.
