Abstract

Additive manufacturing (AM), also known as 3D printing (3DP) has revolutionized the development of components with complex shapes, enabling better developed surfaces favoring aerodynamic shapes, using moldable, and easy-to-reuse materials for aerodynamics, hydrodynamics, energy, and transportation industries. One industry that has been benefited from this progress is the wind generation industry. In this research, a small-scale H-Darrieus type wind turbine is designed to be manufactured by a 3D printer, using a filament of polyethylene glycol terephthalate (PETG) with carbon fiber. The turbine was made a laboratory scale a height and diameter of 0.20 m and 0.22 m, respectively, tested later in a wind tunnel. The maximum power coefficient obtained was 0.21 at a tip speed ratio (TSR) of 0.12. The life cycle of the turbine was analyzed considering manufacturing process, operation, and its disassembly to be recycled or reused. Results show the manufacturing of turbines such as the H-Darrieus is a sustainable solution for the environment and communities. This research shows innovative results in the design, materials, and environmental impact calculations of a low scale wind turbine.
