Application of gel suspension printing system in 3D bio-printing

Clinical applications of soft tissue using 3D bio-printing have been limited due to the difficulty of forming bio-ink materials. In this study, we propose a simple and feasible gel suspension printing system with high printing accuracy using a temperature-sensitive material, Pluronic F-127. The detailed printing parameters of the printing system were confirmed. A heart organ model was successfully fabricated using this printing system, and in vitro cell experiments have demonstrated its good biocompatibility. The results showed that the printing system has the practical ability to prepare soft tissues for application.
