Geosynthetics, especially geogrids, have gained attention in geotechnical engineering for reinforced soil structures due to the ease of construction, adaptability, and strong performance. Among, the material, geometry, and surface characteristics of geogrid significantly influence the reinforcement effect (Hung et al., 2024). Previous research used thermoplastic polyurethane (TPE) to print additive manufacturing (AM) geogrids with square and triangular apertures. Results showed that the TPE geogrids can effectively improve the strength and ductility of soil (Lin et al., 2024, Liu et al., 2024).

This study further examines the effects of different AM materials geogrid—polylactic acid (PLA), acrylonitrile butadiene styrene (ABS), and TPE on soil reinforcement. Results showed that the PLA geogrids always make the greatest contribution to improving soil strength. This may be due to high shear resistance of PLA geogrids. Further study should be done to explore geogrid aperture shape and surface texture to find the optimal pattern, which may serve as reliable data for theoretical and artificial intelligence developments.
