Cell Behavior on 3D Ti-6Al-4 V Scaffolds with Different Porosities.

Porous titanium (Ti) and its alloys fabricated by additive manufacturing (AM) techniques have attractive potential for dental and bone defect repair fields. Understanding the relationship between cells and the surface of the as-built three-dimensional (3D) scaffold interactions is not only necessary for tissue engineering but also promising for improving the fabrication process in the manufacture of artificial implants by AM technology. In this study, we have aimed to investigate the cell behavior including adhesion and proliferation of fibroblasts (L929) on Ti-6Al-4 V scaffolds fabricated by the electron beam melting method.

A Novel Bio-carrier Fabricated Using 3D Printing Technique for Wastewater Treatment.

The structure of bio-carriers is one of the key operational characteristics of a biofilm reactor. The goal of this study is to develop a series of novel fullerene-type bio-carriers using the three-dimensional printing (3DP) technique. 3DP can fabricate bio-carriers with more specialized structures compared with traditional fabrication processes.
