3D printing is additive manufacturing process to fabricate the three-dimensional objects from a digital image files. 3D printing objects from computer-aided design (CAD) file were made by adding material layer by layer. 3D bioprinting has begun to incorporate the printing of scaffolds. These scaffolds can be used to regenerate tissues and organs. Bioprinting scaffold can produce interconnected structures with precise control of pore size or the spatial distribution of pores by the CAD. These pore structure support cell growth and proliferation for tissue regeneration.
In this presentation, we review 3D bioprinting applications in the biomedical field and present research results of Korean Institute of Machinery & Materials (KIMM). We introduced hard tissue scaffold with various pored structure, soft tissue scaffold with cell-laden structure, and vascular scaffold with tube typed structure. These 3D bioprinted scaffold can be considered as an artificial tissue or organ for tissue engineering and regenerative medicine.
