Additive manufacturing techniques of magnetocaloric materials are limited by the fact that melting the magnetocaloric phase has deleterious effects on the functionality of printed parts. In fact, laser melting techniques make the active phase transform, reducing the magnetocaloric response of the sample.
In this talk we present a physical method for the production of uniform polymer based composite filaments for fused filament fabrication. The presence of functional fillers in the composite alters the transformation temperatures of the polymer and modifies the printing conditions. A comparison between the magnetocaloric response of the fillers (Heusler alloys and hydrogenated La(FeSi)13 powders) and that of the filaments and printed parts demonstrate that this printing technique does not affect the functionality of the active material.
