This research explores the utilization of acrylonitrile butadiene styrene (ABS) material for structural applications, addressing the growing demand for polymer composites. Employing fused filament fabrication (FFF) 3D printing with a 2 mm shell thickness, ABS samples were reinforced with basalt, hemp, and glass fibers using epoxy resin to enhance material strength. Mechanical behavior under axial, flexural, and impact loading conditions was investigated, revealing the basalt-reinforced ABS composite's superior performance with a maximum load of 9540 N - three times that of pure ABS (2975 N). The load-bearing capacity of basalt-epoxy reinforced ABS reached 880 N, surpassing glass-epoxy and hemp-epoxy variants. Impact energy was notably higher for reinforced composites (28.9-32.2 KJ/m2) compared to pure ABS (10.3 KJ/m2). The SEM analysis also carried out for better understanding of fracture surface of composites. This study recommends the application of these reinforced ABS composites in structural contexts.
