The United States uses 3D printing to significantly shorten the production cycle of blade mold

the operating environment and scope of the dynamic stiffness testing machine in the past 40 years. Researchers at Sandia National Laboratories (referred to as Sandia) designed a variety of wind turbines with higher efficiency in addition to hardness, which can capture wind energy more effectively than existing technologies, thus reducing the cost of renewable energy. However, it is difficult to manufacture the prototype. Before the production and testing of each type of blade, it takes 16 months to make a set of labor-intensive customized molds

Sandia's partnership with Oak Ridge National Laboratory (Oak Ridge n), the leader in 3D printing, and TPI composites, the largest wind turbine blade manufacturer in the United States (t British PCI film consulting company recently released a report that Pi composites, or TPI), has shown that this time has been shortened to three months. Sandia uses 3D printing technology to directly print the digital design scheme into a mold, shortening the time of more than one year. The figure shows the mold of a relatively small 13m blade. If it is used for larger scale industrial production, the designer can improve the anti risk ability of the technology through experimental design and accelerate the innovation of wind technology

in the cooperation process, Sandia led the blade design, including evaluating the feasibility of using 3D printing; TPI consulted the mechanical parameters and carried out the structural design and CAD geometry required for the successful manufacture of the die; Oak Ridge printed the mold in several parts in just two weeks, and finally assembled the blade mold and manufactured the blades in TPI factory
