Fabrication of a 3D-Printed Horizontal Windmill for Electricity Generation and Water Pumping

Abstract: This study investigates the design, fabrication, and performance of a small-scale horizontal-axis windmill integrated with dual-purpose functionality: electricity generation and water pumping. By leveraging renewable wind energy, the system captures kinetic energy through a 3D-printcd aerodynamic rotor and converts it into mechanical energy, which is subsequently transformed into regulated electrical power. The system incorporates an energy storage and conditioning unit to ensure continuous operation under Fluctuating wind conditions, The stored energy is utilized to drive a diaphragm pump for water lifting, while simultaneously providing il regulated electrical supply for external louds, "The proposed system demonstrates a cost-effective, decentralized energy solution tailored for rural and off-grid regions where access to conventional power and water infrastructure is limited. Experimental evaluations confirm the feasibility of the integrated architecture, achieving stable power conversion and reliable water pumping performance. 'The study underscores the significance of modern fabrication techniques, such as 3D printing, in enhancing the modularity, accessibility, and scalability of small-scale renewable energy systems, The results provide a practical demonstration of how small-scale renewable infrastructure can contribute to sustainable development and resource management in resource -constrained areas.
