DOE Study Explores 3D Printing of Rare-Earth-Free Magnets
A recent study funded by the Department of Energy investigates the potential of additive manufacturing to produce critical rare-earth-free magnets for electrical machines.
Researchers have evaluated the feasibility of using additive manufacturing (AM) techniques to create magnets that do not rely on critical rare-earth elements. These magnets are essential components in various electrical machines, including electric vehicles and wind turbines. The development of such magnets is crucial for reducing reliance on globally concentrated supply chains for rare-earth materials.
The study specifically focused on materials that offer comparable magnetic properties to traditional rare-earth magnets but can be sourced more reliably and sustainably. AM offers a promising pathway for fabricating these complex magnet geometries, potentially enabling novel designs and improved performance in electrical systems. This approach could also lead to more efficient manufacturing processes, reducing waste and energy consumption compared to conventional methods.
By exploring AM for rare-earth-free magnets, the Department of Energy aims to bolster domestic manufacturing capabilities and enhance the resilience of critical energy infrastructure. The findings of this research are expected to guide future development in advanced magnet materials and manufacturing technologies, paving the way for wider adoption in key industrial sectors.
This research addresses a significant bottleneck in electric motor and generator design by exploring AM for rare-earth-free magnets. Success here could reduce reliance on potentially volatile supply chains, a key concern for aerospace and defense applications. It aligns with the broader trend of using AM for functional components, enabling customized magnetic properties and geometries for improved efficiency and reduced material usage.
