An investigation into the layer thickness effect on the mechanical properties of additively manufactured polymers: PLA and ABS

Abstract 3D-printed artefacts are becoming more common, and the effect of printing parameters on their properties is key to performance in applications. Although like build orientation raster direction well-studied layer thickness less well-known. This study determines influence mechanical polylactic acid (PLA) acrylonitrile butadiene styrene (ABS) 3D printed specimens made with fused filament fabrication (FFF). Samples were differing thicknesses tensile tested according ASTM D638. The also found that when increasing for both ABS PLA decreased. When it came ultimate strength, was significant than ABS. Considering as well aspects such time simplicity printing, an optimum print setting could be determined. significantly affected by change compared
