Abstract: A polymer-assisted 3D printing method and ink compositions are used to manufacture magnetocaloric devices having many applications including in heat pumps, refrigerators, etc. The ink compositions and printing methods can produce compositionally graded, anisotropically aligned magnetocaloric architectures with designed pores and channels, to bring forth significant improvement in heat exchange efficiency.
