Other Abstract

This study is based on the multi-nozzle biological 3D printing system and the solvus. The composite tube structure is constructed by using the ultra-low temperature printing technique,the collagen as the wall material and the hydrogel F127 as the core material. After the solution is crosslinked and freeze-dried,the stent is immersed in deionized water at 1℃ to remove the core material. The structure of the collagen lumen is obtained. The technique of gelatin/sodium alginate as the wall structure and gelatin is used as the core. The feasibility of the gelatin regards as a core material for the preparation of tube structure. The structures of collagen and gelatin/alginate lumen stent with good structural and mechanical properties are prepared. The multi-nozzle biological 3D printing system has a good effect in the construction of luminal bio-structure by the method of soldering process,which provides an important manufacturing process base for clinical and regenerative medicine.
