Abstract Scope Our work expands the materials capability in additive manufacturing to enable new thermoelectric energy conversion devices. We apply selective laser melting (also known as laser powder bed fusion) to thermoelectric materials, semiconductors which convert heat to electricity with a solid-state process. This approach could enable new geometries and architectures, nano- to meso-scale structuring, and material-to-device integration. This talk will present the process-structure-property relationships for laser-processed bismuth telluride. We characterize the microstructure and phases, and we measure key thermoelectric properties (Seebeck coefficient, electrical resistivity, thermal conductivity) as a function of temperature. We also demonstrate the impact novel geometries can have on thermoelectric device performance using multiphysics modeling.
