Effect of 3D Printing Parameters on Microstructure of Tissue Engineering Scaffolds
摘要
Abstract
Extrusion-based 3D printing is one of the most important techniques for preparing tissue engineer-ing scaffolds.A well-performed tissue engineering scaffold must have an internal microstructure with small pores and high porosity.A thermo-mechanical coupling dynamics model of printing material forming process is established for the scaffold forming dynamic process in extrusion-based 3D printing.The influence of the main parameters in printing process on the pore size and remelting properties of the formed scaffold is studied by numerical simulation.The results show that the pore size of the scaffold increases with both the printing time interval and material viscosity increasing,but with the substrate temperature decreasing while the re-sults of the remelting degree of the scaffold is competely opposite;and the change of material viscosity has the most obvious influence on the pore size and remelting degree of the scaffold formed.关键词
