The National Science Foundation awarded a $135,113 Project Grant to the University of Michigan under the Engineering (47.041) federal grant program. The grant will support research to develop an additive manufacturing process using selective laser melting for thermoelectric waste heat recovery materials and devices. Key activities include establishing a correlation between laser processing variables and thermoelectric material characteristics to provide a net-shape and scalable additive manufacturing method. Researchers will test hypotheses regarding using non-equilibrium laser conditions and nano-particles to reduce thermal conductivity and improve properties. The laser-based additive manufacturing process aims to enable graded doping, variable cross-sections, and direct manufacturing of thermoelectric materials, insulation, conductors and heat exchangers as an integrated energy harvesting system. Outcomes include increased efficiency of energy systems and reduced U.S. dependency on foreign energy sources.
