Manufacturing processes used to develop permanent magnets are time-consuming and demand very specific machinery able to apply exceptionally high pressures, temperatures, and magnetic fields. Furthermore, these manufacturing processes generate by-products and hazardous waste, making the whole process not environmentally-friendly. On the other hand, as a main advantage, the magnets produced using such approaches present extremely large magnetic fields. In this work we address this problem using 3D-printing technology to develop polymer-based permanent magnets, a much simpler technique that allows production in a more time-efficient and environmentally-friendly manner and permits to develop different types of magnets by simply modifying specific parameters of both the matrix and the filler. Here we report on the results of attempting to 3D-print magnetic materials on the micro-scale and their full magnetic characterization. 3D-printing materials with different magnetic properties at this scale, allows their application in a wide range of applications such as in biomedicine, biotechnology, medical science, and information storage among many others. The M-H hysteresis loops, the curves of the change of magnetic moment, and the surface plots of the magnetic field intensity and orientation of the 3D-printed samples before and after magnetic poling are shown in Fig. 1 and 2, respectively.
