| Abstract Scope |
The development of environmentally sustainable and energy-efficient cooling technologies requires both novel functional materials and advanced processing methods. Magnetocaloric materials, including NiMn-based metamagnetic shape memory alloys and La(FeSi)13-based compounds, exhibit significant entropy changes near structural and magnetic phase transitions, making them suitable candidates for solid-state refrigeration. In this work, both alloy systems were formulated into printable inks using hydroxypropyl cellulose as the binder medium and deionized water, achieving high solid loadings of up to 98 wt.%. The composites were processed via screen-printing and direct ink writing to fabricate 2D and 3D structures. Post-printing treatments included polymer removal by calcination and sintering to obtain dense metallic structures with porosity below 8 vol.%. Structural and magnetic characterization confirmed the preservation of the magnetocaloric performance in both systems, with La(FeSi)13 samples showing a slight increase in Curie temperature after printing. These results highlight the viability of additive manufacturing for next-generation magnetocaloric cooling devices. |
