3D Printing for wind turbine blade manufacturing: a review of materials, design optimization, and challenges

Abstract

and 3D Printing-enhanced Large-Scale Additive Manufacturing (LSAM), are examined in detail for complex and large-scale wind turbine blade production. Materials used in 3D printing wind turbine blades, such as thermoplastic composites, epoxy resins, and fiber-reinforced polymers, are assessed with a focus on their mechanical strength, durability, and environmental considerations. Furthermore, the importance of design optimization and customization for wind turbine blades, including aerodynamic and structural design optimization, is emphasized. Customization for site-specific conditions, infill structural optimization, and infill printing speed and cost are also discussed. The review highlights the importance of structural optimization in developing efficient and cost-effective 3D-printed wind turbine blades, customization for site-specific conditions, and infill structure. The review also mentions these technologies' challenges, such as material limitations, surface finish quality, size limitations, and structural integrity. Therefore, addressing these challenges to utilize these technologies' potential fully is crucial.
