报告内容:

3D printing technology can create a three-dimensional object using 3D CAD model by printing successive layers of various materials under computer control. The 3D printing technology can be applied to the biomedical field to produce tissue engineered constructs imitating complex organ or tissue structure. 3D bio-printing technology makes it possible to not only fabricate 3D shape, but also precisely place various cell in a single structure. In this talk, I will introduce 3D bio-printing system (3DBP) and its bio-applications. The 3DBP can fabricate the 3D polymer scaffold which serves a 3D supporting structure for cell adhesion and proliferation for artificial organ. The system has data conversion software which can convert 3D CT/MRI files into the NC code. And the system composes of multi-dispensing module, high precision multi-axis stages and controller. It can control the shape, size, pore size and porosity of the scaffold. I will also present the cell printing system which can fabricate 3D hydrogel scaffold. The greatest advantage of the cell printing system is that it can fabricate the cell-laden hydrogel scaffolds. Homogenous encapsulation of the cells can be done using the cell printing system. Both systems can fabricate 3D scaffolds with interconnected porous structures to increase the efficiency of the transport of the nutrient and waste. The mechanical properties of the scaffold, proliferation and differentiation of the cells are compared with different biocompatible polymers and hydrogels. Finally, I will discuss about the potential of 3D printing technology for artificial organ fabrication.
