Abstract:This study uses a computational fluid dynamics model to investigate the effect of direct ink writing process parameters on the quality of 3D-printed sedimentary materials. The numerical simulation employs the level-set method of the two-phase flow module of COMSOL Multiphysics software. The selected bio-ink consists of the powder portion (45s5 bio-glass and β-TCP nanoparticles) and the polymer portion (polyvinyl alcohol), which has applications in constructing biological bone scaffolds. First, the empirical re… Show more
