论文摘要
在这项工作中，我们展示了使用融合细丝制造的聚合物基质内部单晶磁颗粒的原位简易轴对齐。研究了两种不同的磁性材料：（i）PA6矩阵内的标晶胶质，填充等级：49 vol％和（ii）PA12矩阵内的氮化液，氮化矩阵，填充等级：44 vol％。在外部比对场的情况下，PA6矩阵内的腹膜六膜颗粒可以很好地对齐，而含量为0.7的饱和磁化磁化强度的比例。无法实现氮化亚铁的显着比对。结果表明，使用融合细丝制造使用任意和局部定义的易于轴制造磁铁的可行性，因为用于对齐的永久磁体（或或者是电磁体）可以安装在可旋转的平台上。
Within this work, we demonstrate in-situ easy-axis alignment of single-crystal magnetic particles inside a polymer matrix using fused filament fabrication. Two different magnetic materials are investigated: (i) Strontium hexaferrite inside a PA6 matrix, fill grade: 49 vol% and (ii) Samarium iron nitride inside a PA12 matrix, fill grade: 44 vol%. In the presence of the external alignment field, the strontium hexaferrite particles inside the PA6 matrix can be well aligned with a ratio of remanent magnetization to saturation magnetization of 0.7. No significant alignment for samarium iron nitride could be achieved. The results show the feasibility to fabricate magnets with arbitrary and locally defined easy axis using fused filament fabrication since the permanent magnets used for the alignment (or alternatively an electromagnet) can be mounted on a rotatable platform.
