“…Due to high binder content in low-viscosity DLP inks, binder burnoff is typically a long process with slow ramping rates. To tackle the standing issue of densification in 3D-printed thermoelectrics, inorganic sintering aids, ,, lower-dimensional thermoelectric materials, organometallic precursor solutions, , or high laser power melting , can be utilized. It should be noted that different AM techniques and printing directions may result in varying densities and mechanical properties for the same lattice design, and it is a research area yet to be explored.…”

Thermoelectric generators held great promise through energy harvesting from waste heat. Their practical application, however, is greatly constrained by poor raw material utilization and tedious processing in fabricating desired shapes. Herein, a state‐of‐the‐art process is reported for 3D printing the half‐Heusler (Nb0.88Hf0.12FeSb) thermoelectric material using laser powder bed fusion (LPBF). The multi‐dimensional intra‐ and inter‐granular defects created by this process greatly suppress thermal conductivity by providing numerous phonon scattering centers. The resulting LPBF‐fabricated half‐Heusler exhibits a high figure of merit ≈1.2 at 923 K and a single‐leg maximum efficiency of ≈3.3% at a temperature difference (ΔT) of 371 K. Hafnium oxide nanoparticles generated during LPBF effectively prevent crack propagation, ensuring competent mechanical performance and reliable thermoelectric output. The findings highlight the significant potential of LPBF in driving the next industrial revolution of highly efficient and customizable thermoelectric materials.
