| Abstract Scope |
3D and 4D printing have proven to be powerful manufacturing platforms for producing high-performance tissue engineering scaffolds for regenerating body tissues. Compared to other fabrication techniques, they have distinctive advantages for constructing complex scaffolds for regenerating complex tissues such as osteochondral tissue and gastrointestinal tissue. Different 3D printing technologies have different requirements for materials/inks to be used, and in many situations these requirements are highly demanding. The requirements for 3D printing materials/inks in tissue engineering include printability, biocompatibility, biodegradation properties, and mechanical properties of printed products. Regarding 4D printing for tissue engineering, the material/ink availability is very limited. We have been investigating 3D/4D printing in tissue engineering and employing/developing 3D printing technologies such as selective laser sintering, cryogenic or low temperature extrusion 3D printing, and digital light processing. This talk will share our experience in developing new materials, particularly composites and hybrids, for 3D/4D printing of advanced tissue engineering scaffolds. |
