Effect of FDM Process Parameters on the Mechanical Properties and Production Costs of 3D Printed PowerABS Samples

Abstract

The main objective of this study is to analyze of the effect of fused deposition modelling (FDM) printing process parameters on the mechanical properties, printing times and production costs of samples printed with Power Acrylonitrile Butadiene Styrene (PowerABS) filament using a three-dimensional (3D) printer. This study is primarily focused on the effects of the mechanical properties of 3D samples subjected to the influence of three factors; layer thickness (0.15, 0.2, and 0.25 mm), raster angle (15, 45, and 750), table orientation (flat, horizontal, and vertical). For the experiment study, analytical methods such as regression analysis, variance analysis (ANOVA), Signal / Noise (S / N) ratio were used to determine the effect of FDM printing parameters on the mechanical properties with Taguchi optimization method. The results showed that 45° raster angle the highest mechanical properties at each individual layer when compared to 15° and 75°. The results also found tensile strength to directly proportionate to layer thickness. As observed in the results, by improving the material properties, it will be possible to provide support for mechanical engineers and designers to reduce printing time, filament material use and printing costs.
