Energy beam based additive manufacturing (AM) techniques are currently the most-adopted in industry. For functional magnetic materials, there are some disadvantages of these technique that preclude their adoption: large thermal stresses in the build and between build and substrate, a complex thermal history, as well as geometrical restrictions e.g. when building overhanging structures. Binder jetting presents itself as an alternative to energy beam based AM techniques since it does not melt powder during printing, but rather shapes parts with binder in a layer-by-layer fashion.
In this talk, Ni-Mn-based magnetic shape memory alloys and magnetocaloric materials will produced with AM. Properties of laser metal deposited and binder jet printed samples will be compared and advantages and disadvantages of each AM technique detailed. Furthermore, the differences between as-printed and heat-treated sample composition, microstructure, magnetic and functional properties will be shown and compared to samples produced with traditional manufacturing techniques.
