We compared different commercially available materials that are 3D-printable for their suitability for making microwave absorbers by means of additive manufacturing, i.e., 3D printing. For this, we determined their complex permittivity, and, if applicable, the complex permeability. They are responsible for the RF losses within the material and, therefore, determine its usefulness as an absorber material. Further, we made SEM (scanning electron microscope) images of material samples showing the filling materials that have been used to achieve absorbing properties.
我们比较了不同的市售3D可打印材料,以评估它们通过增材制造(即3D打印)制作微波吸收体的适用性。为此,我们测定了它们的复介电常数,以及在适用情况下的复磁导率。它们决定了材料内部的射频损耗,因此决定了其作为吸收材料的实用性。此外,我们对材料样品进行了扫描电子显微镜(SEM)成像,展示了用于实现吸收特性的填充材料。
