The soil water characteristic curve is an important tool in the mechanical and hydraulic analysis of unsaturated soils as it expresses the relationship between soil saturation and suction. The main objective of this research was to analyze, through the retention curve, the feasibility of using a porous structure created with 3D printing as a suction meter. In addition to the retention curve, the accuracy and precision of the manufacturing methodology were also studied through image analysis and sample weighing. Two additive manufacturing techniques were employed. With the first, Fused Deposition Modelling, it was not possible to print pores with a diameter smaller than 1 mm, and, because of this, the technique was discarded. The second technique was Vat Photopolymerization, a minimum pore diameter of 0.6 mm was achieved. Nine cylindrical specimens (CPs) were produced, with identical 0.6 mm diameter pores and the same spacing between them. Five CPs were printed with a radius of 30 mm and a height of 20 mm, and the remaining ones with a radius of 20 mm and a height of 10 mm. The suction measurement method used was the filter paper method. Since the research s goal was not to obtain the exact curve of the printed body but to observe a behavioral trend, an equilibration period of only 7 days was chosen. Placing a paper at the top and another at the base of the CP allowed the analysis of the equilibrium. The difference between the top and base was approximately constant throughout the curve interval, except for the inflection section, where this difference was significantly higher. Two linear sections (on a semi-log scale) connected by a discontinuity were observed. Therefore, a bi-modal model, like those used in filter paper experiments, better described the obtained results. The calibration curve resulted in a suction reading error of 13.7 percent in the first section and 27.5 percent in the second. However, it was considered that the meter is not yet suitable due to the discontinuity region, which made readings between 10 and 1500 kPa unfeasible. Regarding the manufacturing method, it was understood that the printer has adequate precision, with a homogeneous behavior observed among different CPs, even with distinct geometries. The printer s resolution prevented the production of CPs with smaller voids to optimize the curves. However, the curve behavior and equipment precision suggest that additive manufacturing may be capable of contributing to soil mechanics with the creation of a new type of suction gauge, provided a better void configuration/geometry is used to optimize the retention curve behavior.
