Recently, 3D hybrid bioprinting process have been introduced, which concurrently delivers high strength synthetic polymer and bio-inks. The process can produce a sophisticatedly designed 3D cellular structure with substantial size and enough physical properties. Channels for nutrient and oxygen supply can be also incorporated in the 3D structure. To achieve the hybrid printing process, we constructed a bioprinting system. Bio-ink materials were also designed and optimized for the 3D hybrid printing process after which it was applied to the study of 3D printing of cell spheroids, hepatic model, and pre-vascularization. In this presentation, the constructed 3D hybrid bioprinting technology and our recent accomplishments in study of its applications will be introduced. |
