High Viscous Flow Analysis in the 3D Printer by SPH

摘要

The methodology of solidification simulation of high viscous resin using Smoothed Particle Hydrodynamics (SPH) was developed. An implicit scheme was adopted to calculate the viscous term of a high viscous non-Newtonian fluid. The methodology was applied to thermal melting, lamination and solidification of high viscous resin ABS injected from the 3-D printer nozzle. As a result, it is confirmed that this methodology has a potential to express lamination and solidification of high viscous resin.
