• Resumen

  • Extrusion bioprinting is an additive manufacturing technology with huge possibilities in the creation of engineered tissues. There are lots of works regarding to this technology and the materials used. Nowadays researches are using computational simulations to study different parameters that can have influence on the cellular survival. In this way we have done Computational Fluids Dynamics (CFD) simulations to check how the extrusion nozzle geometry affects the flow pressure distribution. Results show that variations in geometry will lead to variations in pressure distribution. It is necessary to perform further simulations in future studies with parametric modifications in nozzle geometries to achieve the optimum nozzle geometry which can help cell survive by reducing the pressure.
