Researchers at the U.S. National Renewable Energy Laboratory (NREL) have developed a novel way of manufacturing wind turbine blades that improves both their performance and end-of-life recyclability.  Rather than creating blades from normal thermoset resins, the team has devised a unique set up for 3D printing them using thermoplastics, which can later be heated to … Continue reading U.S. National Renewable Energy Lab 3D prints 13-meter turbine blade from recyclable resin
