3D Printing Powers Wind Turbine Research at TU Berlin

Researchers at TU Berlin have successfully 3D printed wind turbine blades for research purposes. Using a large-build volume 3D printer, the team created scaled prototype blades measuring 1 meter in length. The 3D printed blades were compared to traditionally made wooden blades, and the researchers discovered that 3D printing allowed for greater experimentation with different infills, shapes, and materials. The use of 3D printing offered efficiency in printing the blades and allowed for customizable complex structures. The blades were printed using BigRep's industrial-grade PRO HT filament and featured a gyroid infill, which provided stability and reduced material usage. The printed blades underwent rigorous structural testing and wind tunnel tests, demonstrating their durability and aerodynamic efficiency. The research paves the way for further studies on enhancing the efficiency of wind turbines using 3D printing technology. Read more
