Abstract Scope |
Thermoelectric energy conversion materials are used for waste heat recovery and thermal management. Traditional thermoelectric manufacturing methods are complex, limited to planar shapes, require use of expensive equipment and result in a substantial loss of material. Additive manufacturing has effectively been used to address these limitations lately. In this research, process-structure-property relationships of three different laser additive manufactured thermoelectric compounds, bismuth telluride (the standard reference material) along with earth abundant copper sulfide and silver selenide were studied. The impacts of various laser processing parameters such as scan speed, laser power, number of scans and scan pattern on microstructural features and thermoelectric properties are reported in this work. |
