Thermoelectric materials are prepared by developing 3D printing technology. The 3D fabricated Bi 0.5 Sb 1.5 Te 3 samples exhibit amorphous characteristics and thus show an ultralow thermal conductivity of 0.2 W m −1 K −1 . 3D printing fabrication readily generates bulk thermoelectric samples of any shape, which is not the case with traditional hot‐pressing and spark plasma sintering methods.
