Ni-Mn-Ga-based magnetic shape memory alloys have been recently fabricated by binder jet 3D printing, direct laser deposition, selective laser melting, and 3D ink printing additive manufacturing (AM). Each of these fundamentally different AM techniques results in functional magnetic materials with very different as-manufactured and final microstructures and properties. While energy-beam-based AM methods melt feedstock powder and build dense as-printed parts, other AM methods, e.g. non-energy-beam-based methods, build highly porous green samples. Nevertheless, for all AM method, post-AM processing is needed to either homogenize highly segregated microstructures or to (partially) densify porous green structures. In this talk, the microstructures and properties of additively manufactured Ni-Mn-Ga magnetic shape memory alloys and post-processing routes will be compared, and paths to functionality will be discussed.
