Title: The Influence of Infill Direction on the Tensile Strength of High-Speed FDM 3D-Printed ABS †
Keywords: 3D-printed, ABS, FDM, high print speeds, infill direction, influence, orientation, tensile strength

Abstract: The paper presents an experimental evaluation of the influence of infill direction (raster angle) on the tensile strength of 3D-printed ABS (Acrylonitrile Butadiene Styrene) samples produced at high speed (200 mm/s infill), flat orientation, and 100% infill density via FDM (Fused Deposition Modeling). The printing material was dried before printing and then stored in a low-humidity environment with desiccant in order to minimize moisture absorption during the experiments. The testing and conditioning of the samples were performed in accordance with the EN ISO 527 standard. The results revealed that the highest mean tensile strength of 39.28 MPa is obtained with the aligned rectilinear pattern at 0° infill direction, while the lowest, 34.56 MPa, is obtained with the same pattern at 90° infill direction relative to the load direction. The tested material demonstrated moderate tensile strength anisotropy in the direction of the load based on the change in infill direction. Moreover, productivity when printing ABS can be significantly increased when the correct conditions are available, as the resulting mean tensile strength is comparable to or higher than that reported by the filament’s producer, which recommends printing at low to moderate speeds for optimal layer adhesion and structural integrity.
