Optimise 3D printing parameter on the mechanical performance of PLA-wood fused filament fabrication

The effect of printing parameter of tensile and compression specimens on production cost and mechanical performance of the material which is PLA with 20% wood content had been identified. The printing parameters selected are nozzle temperature, raster angle and printing speed. The raster angle and printing speed shows higher impact of tensile specimen on production cost while compression specimen only printing speed. Furthermore, for tensile experiment, raster angle gives highest impact than other parameter while for compression experiment each printing parameter giving an equal reaction to mechanical performance. By plotting the S/N ratio graph, higher nozzle temperature, lower raster angle and printing speed show the optimum printing parameters for tensile specimen. While optimum printing parameters for compression specimen are lower nozzle temperature, higher raster angle and printing speed.
