Abstract Scope |
The current social challenges demand new energy-efficient technologies and the ability of obtaining 3D structures in a green and a cost-effective way. Recent progress in caloric materials (magneto- or elasto-caloric) as part of the next generation energy saving devices open new possibilities to explore future technological developments in additive manufacturing. In this way. metamagnetic shape memory alloys are promising candidates for magnetic refrigeration due to their high entropy change around the first-order martensitic transformation, but their crystalline phase is unstable at high temperatures. In this work, we develop original inks and pastes to be implemented in extrusion printing techniques at room temperature to fabricate complex 3D structures using high-performance NiMnSn-based magnetocaloric powders. Cellulose and water were used as green matrix and solvent, respectively. Ink containing more than 85 wt.% of powder was used to print a maximum number of layers of about 250. |
