For its technical and economic reasons, current designs of magnetic materials for electromotors are fairly simple. Technology of add-on production, involving 3D printing, represents a step towards newer and more advanced electric motor shapes. For that we have to provide a certain type of magnetic material, which is transformed into a permanent magnet via 3D printing, which is capable of creating certain shapes of magnets, nearly impossible to create with conventional methods, and produce next to zero waste.
If we want 3D printed permanent magnets to become a part of the industry, three-dimensional products must compete with conventional products. To have an adequate comparison, I compared magnets, made by add-on production with conventional production, by comparing creation time, accuracy, physical, mechanical and magnetic properties. To conclude I tried to predict whether 3D printing technologies will succesfully integrate themselves in the industry or will remain as a prototype and modelling tool.
