Analysis of deposition modeling by particle method simulation

Abstract

Currently, the spotlight for new type production method is on 3D printers instead of conventional production such as injection and extrusion molding. One of the widespread 3D printing method is the deposition modeling method. In the deposition method, the melted material is injected from the nozzle and deposited on the substrate. The final shape of the produced objects depends on viscosity, surface tension of materials, migration speed of nozzle and injection speed. In this study, we develop and simulate the deposition modeling using one of the particle methods, Smoothed Particle Hydrodynamics Method. The height and width of the produced products are examined in various viscosities and injection speeds. The results show that high viscosity and slow injection speed are favorable to produce the objects.
