Abstract Scope |
Thermoelectric (TE) materials have long been of interest for their ability to convert thermal energy to electrical energy directly. However, TE devices traditionally have a low conversion efficiency and remain uneconomical for many applications. Additive manufacturing has recently gained interest as a means to decrease TE production cost and increase conversion efficiency through unique geometries. Most studies have investigated powder bed fusion printing; binder jetting printing is a low cost, high throughput additive manufacturing technique that has yet to be investigated with TE materials. In this study, TE materials such as silicon germanium were powderized using ultrasonic atomization to control spherical morphology. The effects of binder jetting process parameters on sample density were investigated. The thermal transport properties were measured to evaluate the TE material performance. X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy dispersion spectroscopy (EDS) were used to characterize the powder, green part, and final component. |
