“…However, the two main factors hindering the applicability of these technologies are the difficult optimization of process parameters (thus complicating the achievement of the process reproducibility) and the high process costs (as an example, magnetron sputtering requires a high vacuum chamber to maintain high quality during deposition, high voltage discharges, and highly expensive magnets [241][242][243]). Therefore, research has focused on deposition technologies that can guarantee high quality materials but with lower economic costs [233,234,238,[244][245][246][247]; currently, inkjet printing and aerosol jet printing are candidates satisfying such requirements, since a variety of promising cases have been collected in literature [248][249][250]. Aerosol jet printing (AJP) is especially interesting thanks to the possibility of using almost any material dispersed in a liquid phase [251][252][253].…”

Solid-state energy conversion has been established as one of the most promising solutions to address the issues related to conventional energy generation. Thermoelectric materials allow direct energy conversion without moving parts and being deprived of greenhouse gases emission, employing lightweight and quiet devices. Current applications, main thermoelectric material classes, and manufacturing methods are the topics of this work; the discussion revolves around the crucial need for highly performing materials in the mid-temperature range, and around the development of more scalable fabrication technologies. The different manufacturing methods for thermoelectric bulk materials and films are also discussed. Small-scale technologies are generating increasing interest in research; the high potential of aerosol jet printing is highlighted, stressing the many advantages of this technology. A promising approach to scale the production of miniaturized thermoelectric devices that combines high energy ball milling and aerosol jet printing is proposed in the conclusion.

“…The research method of the paper includes two pillars: the search/identification of existing applications of 3D printing and the analysis/evaluation of the selected case-studies. Regarding the first pillar, and in the context of the set of results, we focused on three AM methods (see Table 1) whose contribution in circular benefits (repair, remanufacturing and refurbish) have been also spotted in the corresponding literature [10][11][12][14][15]. In this line, we identified 27 case studies based primarily on academic publications, also including a small number of technical reports.…”

Additive Manufacturing (AM), also popularly known as 3D Printing, refers to a group of manufacturing methods which are guided by a digital model and use incremental addition of material, usually in a layer-by-layer manner, for the fabrication of objects. Lately, AM is widely used in both industry and academia, exhibiting, among others, the advantages of flexibility and ability to produce on demand, with reduced cost, time and waste. This paper seeks to shed light on the contribution of 3D printing in the transition towards the objective of circular economy. Towards this end, we focus on three AM processes (Cold Spray, Direct Energy Deposition, and Powder Bed Fusion), and we review 27 distinct case studies in the laboratory as well as industrial settings, exploring their circularity based on the comprehensive 9R framework (recover, recycle, repurpose, remanufacture, refurbish, repair, reuse, reduce, rethink, refuse). Overall, the results provide a structured assessment of the degree of circularity, and identify the dominant “R” strategies employed by the specific methods of AM. They also reveal the positive impact, and the corresponding advantages, of 3D printing in the extension of product(s) life cycle, with respect to specific material and industry sectors.

“…The new layer is deposited by creating metallurgical bonding with the first layer along the profile under the guidance of computer. A similar process, in which latter layers are sequentially created on the preceding layer, is repeated to build a three-dimensional (3D) part layer-by-layer [8,9]. Owing to the features of the laser beam and layer-by-layer process, laser material deposition possesses advantages including high production flexibility, low thermal inputting, and high geometry freedom [10,11].…”

As a very common type of laser additive manufacturing technology, laser material deposition (LMD) is widely used, having exceptional application advantages including surface enhancing, repairing damaged parts with high value-add, and building functionally graded material. At present, the continuous wave laser is a common laser mode used in the LMD process. The investigation of pulse shaping, which can add a degree of control over the thermal history, is limited. In this study, the effects of pulse shaping on the geometrical characteristics, microstructure, and microhardness were investigated through conducting single-track experiments with different laser shapes, including continuous, rectangular, ramp up, ramp down, and hybrid ramp. The results indicated that the clads created by continuous and ramp up laser shape presented the maximum and minimum dimensions of geometrical characteristics, respectively. The rectangular and hybrid ramp laser shape deposited the clads with similar dimensions. The continuous laser shape produced the clad with the coarsest microstructure and lowest hardness because of the lowest cooling rate. The smallest grain size and highest hardness presented in the clad were seen with the rectangular laser shape owing to the biggest cooling rate. The cooling rates in ramp up and ramp down were restrained by the gradual heating and gradual cooling, respectively.
