Abstract:
Nowadays, Additive Manufacturing (AM) has revolutionised current production methods in many areas like aeronautics, military or medicine. Among these methods, Laser Powder Bed Fusion (L-PBF) is prevalent to printing complex metallic parts for small and medium series. Recent studies in L-PBF processing develops the production of new materials via this process, including thermoelectric (TE) materials. This study presents the manufacturing of silicon-germanium alloy by L-PBF, a TE material intended for high temperature applications. It is the first time that this material is manufactured by AM technology. Several dense samples were produced, and a first process window was identified. Structural analyses have been performed, highlighting very good densification but unfortunately mechanical cracking.
