Yunfeng Liu, Xing Tao Dong, Fu Dong Zhu

Open full text 12 citations

Abstract

The scaffolds of bone tissue engineering (BTE) are designed with complex interconnected pores for providing mechanical support, cell attachment and nutrition delivery, and can be directly fabricated via rapid prototyping (RP). Based on reviews on amount of papers, fundamental of BTE, including research procedure and biomaterials for scaffold are presented. And various RP methods for scaffold fabrication, including selective laser sintering (SLS), fused deposition modeling (FDM), 3 dimension printing (3DP), are introduced. The conclusions including existing problems and future researches about BTE scaffold fabrication are given at the end.
