Study of the effect of the fused deposition 3D printing process on the tensile properties of ABS specimens

To study the influence law of parameters such as print layer thickness, print speed, placement angle, and fill angle on the tensile properties of specimens in the process of fused deposition 3D printing of ABS specimens, a 4-factor, 3-level orthogonal experiment was used, and through the range analysis deviation and analysis of variance of the test results, the magnitude of the influence of the four factors on the tensile properties of ABS specimens was obtained in the following order: placement angle, fill angle, print speed, and print layer thickness. The level of influence of the placement angle was significant, and the optimum tensile properties of ABS specimens were determined within the range of orthogonal tests to be obtained at a print layer thickness of 0.3 mm, a print speed of 55 mm/s, a placement angle of 45°, and a fill angle of 90°. The results of this study are of great significance for the in-depth analysis of the relationship between the placement angle and the tensile properties of the specimens and provide a certain theoretical basis for the optimization of the 3D printing parameters of the actual ABS specimens.
