Impact score: 13
The IMDEA Materials Institute in Spain has developed a low-loss metallic glass 3D printing process, aimed at high-efficiency motor cores. The grain-boundary-free structure of metallic glass gives it far lower hysteresis losses than silicon steel laminations, but traditional casting/strip methods struggle to form complex core geometries, and 3D printing offers a new path to direct shaping. The research used laser melting to build amorphous alloy layer by layer, verifying the feasibility of printing magnetic motor components with complex geometries; if industrialized, it will create new demand for iron-based amorphous alloy powders. Iron-based amorphous alloy powder suppliers can track the progress of metallic glass motor pilot projects, as this route imposes stricter requirements on powder purity and oxygen content control.

IMDEA 3D打印低损耗金属玻璃，电机铁芯效率再提升
西班牙IMDEA材料研究所开发出低损耗金属玻璃（metallic glass）3D打印工艺，目标用于高效电机铁芯。金属玻璃无晶界结构使其磁滞损耗远低于硅钢叠片，但传统铸造/带材法难以成形复杂铁芯几何，3D打印直接成形打开新路径。研究通过激光熔融逐层成形非晶态合金，验证了复杂几何电机磁性部件的打印可行性；若产业化，将催生对铁基非晶合金粉末的新增需求。铁基非晶合金粉末供应商可跟踪金属玻璃电机中试进展，该路线对粉末纯度和氧含量控制要求更严。
