In the fields of engineering, biomedicine, andaerospace, they have a variety of uses. Therefore, theresearchers aim to reduce costs by balancing materialstrength and lightweight. To study the impact of the porositygradient through thickness, samples of PLA material weredesigned and created using a 3D printer by internationalstandard specifications. An experimental three-pointbending test was performed, and then simulations wereperformed using ANSYS 2022 R1 software on samples withfunctionally gradient different porosity layers to verify theexperimental results.The results from the experiment andthe numerical values were aligned with an error rate of nomore than 13%. The maximum bending load and maximumdeflection of the beam were specified experimentally andcompared with the numerical solution. The maximumbending on the minimum deflection When the porosity layerin the middle of the beam matched the ideal maximumbending load (190,194) N experimentally and numerically,respectively. The minimum deflection (5.9,6.4) mmexperimentally and numerically, respectively, was obtainedin samples with varying porous layers.
