Advancement made in 3D printing anisotropic magnets
The U.S. Department of Energy’s Critical Materials Institute has taken a major step toward printed, aligned anisotropic magnets via additive manufacturing processes. Hybrid nylon bonded neodymium-iron-boron and samarium-iron-nitrogen magnets were manufactured using the Big Area Additive Manufacturing (BAAM) located at Oak Ridge National Laboratory. The research is discussed in the paper, “Additive Manufacturing of anisotropic hybrid NdFeB-SmFeN nylon composite bonded magnets,” co-authored by Kinjal Ghandha, Ling Li, I.C. Nlebedim, Brian K. Post, Vlastimil Kunc, Brian C. Sales, James Bell, and M. Parans Paranthaman; and published in the Journal of Magnetism and Magnetic Materials.
