“…Indeed, there are very few reports in the literature employing the SLM technique in the preparation of thermoelectric materials. In 2016, El-Desouky et al 20,21 tried to process Bi 2 Te 3 by the SLM technique, and explored the effect of various processing parameters on the depth of the molten pool and on the resulting microstructure. However, the chemical composition and thermoelectric properties of their SLM-processed samples were not studied.…”

Commercial production of thermoelectric (TE) modules features energy-intensive and time-consuming processes. Here, we propose a rapid, facile and low cost fabrication process for n-type single phase Bi 2 Te 2.7 Se 0.3 that combines self-propagating high-temperature synthesis (SHS) with the laser nonequilibrium 3D printing method based on selective laser melting (SLM). The optimal SLM processing window for high quality single layers has been determined. Results show that the chemical composition of the sample is very sensitive to the laser energy density (E V ) due to the selective vaporization of Se and Te. For energy densities E V of less than 33.3 J mm À3, the composition of the SLM-processed samples is relatively stable. However, as E V exceeds 33.3 J mm À3 and increases further, the vaporization rate of Te and Se significantly increases and is much higher than that of Bi. Empirical formulae relating the chemical composition of the resulting materials with the values of E V are obtained and are used to predict the composition of the SLM-processed material. Most importantly, the temperature dependent TE properties of the SLM-fabricated bulk sample result in a maximum ZT value of 0.84 at 400 K, which is comparable to that of the commercially available material. The work has laid a foundation for the future utilization of this technique for the fabrication of Bi 2 Te 3 -based thermoelectric modules.

“…Selective laser melting (SLM) has been widely used in the manufacturing of structural materials and components , but, so far, rarely applied to functional materials and devices, such as TE modules, This is due primarily to the difficulties with preparing appropriate forms of a powder, which should preferably feature spherical grains with proper size distribution and an excellent ability to flow. In 2016, EI‐Desouky et al tried to process Bi 2 Te 3 using the SLM technique, and found that the Bi 2 Te 3 powder could be consolidated by laser processing, although the process used in their research was based on a compacted powder pellet, the technique far from that practiced in the commercial SLM where a powder bed of loosely stacked spherical particles is typically utilized. Moreover, the traditional powder‐bed technologies can only handle one type of powder in a single‐building period.…”

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 noncontact 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 À152 mV K À1 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.

The patented thermoelectric intensifier of heat transfer between two moving media with different temperatures was investigated. In its design, to increase the intensity of heat exchange between media, the use of fan units is provided. A mathematical model of the device was developed, based on the solution of the heat balance equation for media flows in transport zones for forward flow conditions. The calculated data are presented in the form of the dependence of the temperature change of moving media along the length of the intensifier for different values of the heat transfer coefficient between the junctions of the thermoelectric battery and the air medium in the gap of the device. It has been established that the larger the temperature difference between the inlet media, the more abrupt the dependence of the limiting length of the thermoelectric battery on the heat transfer coefficient will be.
