Recent developments in additive manufacturing (3D-printing) give the possibility of production of magnet structures which are not possible to obtain by using conventional methods. 3D-printing started as a pioneering method for polymer and ceramic materials giving the opportunity of rapid prototyping. First attempts have been made now in the production of permanent magnets. In this work, we used different polymers (PLA, PA12) and commercial magnet powders (MQA, MQP-S) for the production. We compare the properties of polymer bonded magnet with magnets made by Fused Deposition Modeling (FDM) and Laser Powder-Bed Fusion (LPBF). For the comparison of these different production routes, we investigate the microstructure and magnetic properties (Br, Hc,(BH) max) and the density (filling ratio of the magnetic material) of the produced samples.
