Oak Ridge National Laboratory, in collaboration with the National Renewable Energy Laboratory (NREL) and industry partner Vestas Wind Systems, published a report comparing additive manufacturing—or 3-D printing—processes to produce a component that connects structural beams in the enclosure containing a wind turbine’s energy-generating components (the nacelle). Co-funded by WETO and DOE’s Advanced Manufacturing Office, the study concluded that additive manufacturing could have promise based on future economics and technology advances.
