The manufacturing cost has been a bottle neck for broader applications of thermoelectric (TE) modules. We have developed a rapid, facile, and low cost method that combines non‐contact dispenser printing with selective laser melting (SLM) and we demonstrate it on n‐type Bi 2 Te 3 ‐based materials. Using this approach, single phase n‐type Bi 2 Te 2.7 Se 0.3 thin layers with the Seebeck coefficient of −152 µV K −1 at 300 K have been prepared. Assembling such thin layers on top of each other, the performance of thus prepared bulk sample is comparable to Bi 2 Te 3 ‐based materials fabricated by the conventional techniques. Dispenser printing combined with SLM is a promising manufacturing process for TE materials.
