奥地利维也纳技术大学的研究人员研制出一种特殊的3D打印机,能够打印出拥有复杂形状和精确定制磁场的永久磁体,为特殊磁体的制造开辟了新途径,可用于制造磁性传感器等器件。通常,采用喷射成型方法制造磁体时,研究人员需先在计算机上设计磁体,并不断调整其形状,还需制造模具,耗时且昂贵。维也纳技术大学的研究人员开发的磁体打印机与传统的3D打印机功能类似,但其以特制的磁性微颗粒长丝为原料,打印机加热材料并使用喷 Researchers at the Technical University of Vienna in Austria have developed a special 3D printer that can print permanent magnets with complex shapes and precisely tailored magnetic fields, opening up new avenues for the manufacture of specialized magnets that can be used to make devices such as magnetic sensors. In general, when producing a magnet by injection molding, researchers need to design a magnet on a computer and continually adjust its shape. The need to make a mold is time consuming and expensive. Magnet printers developed by researchers at the Technical University of Vienna are similar in function to traditional 3D printers but using specially made magnetic micro-particle filaments as raw material, the printer heats the material and uses a spray
