Geosynthetics commonly utilize plastic materials. The utilization of plastic items presents a significant environmental hazard because of their decomposition, focusing on the environmental issues arising from the limited ability to directly degrade conventional plastic geogrids, as well as the impact of material-filling patterns, filling forms, filling ratios, and tensile rates on the mechanical properties of geogrid. A polylactic acid (PLA) geogrid was fabricated using 3D printing technology and subjected to indoor tensile tests. An analysis is conducted on the mechanical properties of geogrid, focusing on the effects of material-filling patterns, filling forms, and filling ratios. The test findings indicated that PLA is a viable and eco-friendly material for manufacturing geogrids. Furthermore, it accurately represents the mechanical characteristics of various geogrids. The Gyroid printed biaxial geogrid has a higher strength when the filling ratio is 50%. As the elongation increases, the slope of the curve decreases more in Gyroid 0 degree printed biaxial geogrid. As the filling ratios rose, the tensile strength of the geogrid initially increased and subsequently declined. Notably, at 51% filling ratio, Gyroid 0 angle and Gyroid 45 angle printed geogrid show the same tensile strength.
