THERMOLEG-3D, a new research project funded by theANR : Development of 3D thermoelectric legs (LEGs) using binder jetting coupled with spark plasma sintering: Impact of manufacturing parameters, through to module assembly.

Thermoelectric (TE) compounds can convert waste heat into useful electrical energy (energy recovery) when formed into components called legs (or LEGs). There is a need to reduce the production cost and manufacturing time of these LEGs. The project aims to study the technical feasibility of manufacturing these LEGs with optimized properties using an innovative method: additive manufacturing via binder jetting coupled with a sintering step. In fact, using this approach would make it possible to design complex shapes conducive to better energy conversion.

The project coordinator is Y. Thimont of the CIRIMAT (UMR 5085 CNRS/University of Toulouse 3)

CRISMAT (UMR 6508 CNRS/University of Caen Normandy, ENSICAEN) andIMN (UMR 6502 CNRS/University of Nantes) are partners in the project.

At the IMN, David Berthebaud and Olivier Hernandez fromthe MIOPS team, as well as Pierre-Emmanuel Petit, are involved in the research project.
