In this chapter, we review the progress in printing microstructures made of magnetic nanoparticles as active elements from self-assembly approaches on substrates to scanning probe lithography for 2D digital pattern generation and more complex 3D microstructure fabrication. Over two decades, dip-pen nanolithography has been developed to create chemical templates to bind nanoparticles, direct-write nanoparticles or synthesize them on the substrate. While 2D printing of magnetic nanoparticles has extensively been explored, additive manufacturing technologies require a further degree of improvement in terms of resolution and optimization of functional materials. However, pioneering work on the fabrication of magnetic-responsive micromachines through vat polymerization techniques has opened the path to this promising new field.
