The efficiency and reliability work best in renewable energy systems highly dependent on the wellness of the designing of wind turbine blade. Additive manufacturing, namely 3D printing, opens new possibilities for manufacturing scaled models with complex geometries and advanced materials. This paper brings a significant study on the modal and fatigue life analysis of a wind turbine blade using ANSYS software which is 3D printed with the scale of 1:3.75, and further validated in the experimental view. Fabricated out of 0-degree-oriented carbon-fiber-reinforced PLA, the blade is extensively studied for structural integrity and vibrational response. Geometric and dynamic scaling laws are applied to ensure an accurate representation of full-scale blade behavior in scaled models. Modal analysis in ANSYS Workbench elucidates mode shapes and frequencies, while fatigue life analysis assesses structural durability under realistic loading conditions. Experimental testing employs precision instrumentation, validates numerical predictions, and confirms enhancements in structural integrity achieved through design modifications. The findings underscore the efficacy of additive manufacturing and iterative design optimization in advancing wind energy infrastructure, exemplifying a symbiotic fusion of computational modelling and experimental validation.
