Simulations of Extrusion 3D Printing of Chitosan Hydrogels

Extrusion-based three-dimensional (3D) printing has recently become a major field that provides significant benefits, as it is principally employed to fabricate 3D scaffolds, exploiting soft biomaterials. The hydrogel-based ink requires crucial properties, such printability and fidelity the appropriate structure. However, typically uses trial error techniques achieve structure, which wastes material time. This study multiphysics simulation predicate potential of chitosan hydrogel desirable biomaterial used in tissue engineering. flow was presumed be laminar two-phased simulations. Furthermore, impact different velocities viscosities extrusion-based investigated. Moreover, model validation printed investigated confirm outcomes for high-quality printing. effect settings studied during experimental test. results obtained from experiments provide information deciding optimum parameters chitosan-based with high quality.
