“Very large wind blade molds will be printed on the world’s largest polymer 3D printer located at the UMaine Composites Center using recyclable bio-based materials reinforced with wood,” said Habib Dagher, executive director of the Advanced Structures and Composites Center. “By combining cutting-edge 3D printing manufacturing with bio-based feedstocks, our team estimates that new blade development costs can be reduced by 25% to 50% and accelerated by at least 6 months. Molds produced using these materials can be ground up and reused in other molds, making them a more sustainable solution.”

“Oak Ridge National Laboratory will apply expertise in additive manufacturing, carbon fiber technology and materials science to advance the use of 3D printing in wind energy applications,” said ORNL’s Xin Sun, interim associate laboratory director for energy science and technology. “We look forward to collaborating with UMaine to optimize these clean energy technologies to benefit the environment and boost the economy.”
