Lattice Boltzmann multicomponent model for direct-writing printing

We introduce a mesoscale approach for the simulation of multicomponent flows to model direct-writing printing process, along with early stage ink deposition. As an application scenario, alginate solutions at different concentrations are numerically investigated alongside processing parameters, such as apparent viscosity, extrusion rate, and print head velocity. The present offers useful insights on rheological effects upon printed products, susceptible geometric accuracy shear stress, by manufacturing processes complex photonic circuitry, bio-scaffold fabrication, tissue engineering.
