Abstract：BACKGROUND: With the development of 3D printing technology, organ and tissue construction can be achieved by constructing a three-dimensional scaffold that is conducive to cell growth. OBJECTIVE: To solve the scaffold over-accumulation during 3D printing.METHODS: Fluent, a finite element analysis software developed by ANSYS Company in the United States, was used to analyze the extrusion process of print heads and to obtain suitable viscosity and extrusion pressure of materials for the 3D printing of cellulose gel composites. We then compared simulation results with experimental results. RESULTS AND CONCLUSION: The error between simulation results and experimental results was less than 5%. The simulated values at a kinetic viscosity of 45 and a pressure of 0.10-0.12 MPa solved the phenomenon of over-accumulation of cellulose gel composites during the 3D printing process, ensuring enough space for the 3D printed scaffold.
