This CMI-funded research was conducted at Ames Laboratory and Oak Ridge National Laboratory, in a collaboration between CMI projects Additive Manufacturing of Polymer Bonded Magnets (2.1.11) and Recovery of Critical Materials from Dilute Electronic Waste Streams (3.3.13).
Successfully demonstrated recycling of additively manufactured (AM) rare earth magnets with nearly 100% yield and no magnet degradation
Significance and Impact:
- Reduced manufacturing wastage and potentially offset any rare earth element demand and low production costs
- Research advances efforts to ensure sustainability in critical materials by forming a close loop supply chain
Details and Next Steps:
- Remanent magnetization and saturation magnetization increased by 4% and 6.5% respectively, due to enhanced density by 6% while coercivity and energy product were retained from the original additive printed bonded magnets
- Being extended to anisotropic AM gap magnets
