Abstract Scope |
Additive manufacturing of thermoelectric devices enables unprecedented customization of thermoelectric devices. Our prior work communicated the process-structure-property relationship for laser-based additive manufacturing of thermoelectric materials for low and high temperature applications, namely bismuth telluride and silicon germanium compounds. We build upon this work to show how additive manufacturing is leveraged to tune both intrinsic and extrinsic thermoelectric material properties, enabling customization of devices for specific applications without necessitating substantial changes in the manufacturing process. Machine learning approaches are used to determine how adjustments to process parameters such as laser power and scan speed result in graded thermoelectric properties. For example, Seebeck coefficients that range from positive to negative values are achieved in the same material using controlled adjustment of laser processing parameters. We present an analysis of which thermoelectric materials are most conducive to laser-based additive manufacturing with results on processing of the most promising materials based on that analysis. |
