Numerical Modeling of the Material Deposition and Contouring Precision in Fused Deposition Modeling
Abstract
We present a numerical model of the material deposition in fused deposition modeling. The flow of the material extruded from the printing head nozzle is simulated within the computation fluid dynamics (CFD) paradigm. The molten thermo plastic is modeled as an incompressible Newtonian fluid with a free surface. The numerical model provides a prediction of the shape of the printed road. Four deposition strategies are investigated to print a road along a tool path with a 90° turn. The investigated scenarios include the ideal case of an extrusion rate synchronized with the printing speed, as well as the cases of a sharp tool path with a stop-at-turn trajectory, and as moothed tool path with blended acceleration. The CFD simulation provides a way to optimize the tool path planning and the deposition strategy, in order to improve dimensional accuracy in extrusion-based additive manufacturing.
