Effects of Build Orientation and Raster Angle on Total Cost, Dimensional Accuracy, and Tensile Properties of Various Fused Filament Fabrication Parts 2022-01-5106

One of the crucial factors determining mechanical behavior, dimensional accuracy, and total cost is part orientation and raster angles. To investigate the impact of this parameter the standard specimen on PLA and ABS parts are fabricated by using fused filament fabrication (FFF) at various orientations and raster angles. In this regard, three build orientations and three raster angles were taken into consideration. Before the mechanical characterization by the tensile test, the primary dimensions and weight of the produced samples are then measured. Therefore, the result shows that the tensile strength increases with decreasing raster angle and by aligned from upright to flat direction for both material because of the fracture mode and loading direction. Also, the manufacturing orientation and raster angles significantly affected the dimensional accuracy and total cost. In terms of material, result showed that PLA has lowest total cost and highest tensile strength compared to ABS. In light of this, the purpose of current work is to complete tensile experiments to investigate the impact of flat, on edge and upright build orientations as well as raster angle on the total cost, tensile strength, and dimensional accuracy for PLA and ABS material. The results of this investigation will advance our understanding of ideal printing angles and build orientation.
