摘要：

Thermoelectric materials are prepared by developing 3D printing technology. The 3D fabricated Bi0.5Sb1.5Te3 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. © 2015 WILEY-VCH Verlag GmbH & Co.
