Abstract(s)
The effect of the key 3D printing manufacturing parameters [Infill pattern and Build orientation] on the influence of mechanical strength of two thermoplastic filaments used in Fused Deposition Modelling [FDM] or Fused Filament Fabrication [FFF] method. I e. Acrylonitrile Butadiene Styrene [ABS] and Acrylonitrile Stereyne Acrylate [ASA], which is touted as a potential successor to ABS were inspected in this academic work. From experimental findings, it tentatively suggested that the tensile, flexural, and compressive strength of the ABS specimens is consistently higher than that of the ASA specimen. The empirical findings of ABS purportedly show a lower variance and optimum reliability than in the case of ASA. Tension tests indicate the ultimate strengths for Y oriented ABS specimens are marginally highest. The minor variations in ultimate tensile strengths are relevant for all pairwise correlations for different orientations of the ASA specimens. The findings of the flexural and compressive tests are well correlated with the results of the tension tests, again signaling that the flexural and compressive abilities are relatively high for Y oriented ABS and Vertical ABS model, respectively. Another imperative observation that was voluntarily made while printing ASA is, it was more prone to warping when compared with ABS, as a broader trend, Y orientation, and Rectilinear Infill offered greater strength to the exposed parts investigated on both the materials. These experimental findings further indicate that the processing parameters, such as Build Orientation and Infill Pattern of the FDM specimens, directly contribute to impacting the mechanical strength of the tested materials
