“…Especially, for conductive polymeric filaments, there are gaps for improving electrical and conductive properties. In another study, Hüner et al 96 prepared graphene-based 3D printed electrodes using the 3D printing method and then were co-deposited with different molar ratios of Ni and Pt to examine the HER features of the electrodes in the alkaline medium. In the electrochemical measurements of the prepared electrodes, they determined that the uncoated graphene-based electrode had the least HER kinetic activity in an alkaline medium.…”

Additive manufacturing (AM) technologies have many advantages, such as design flexibility, minimal waste, manufacturing of very complex structures, cheaper production, and rapid prototyping. This technology is widely used in many fields, including health, energy, art, design, aircraft, and automotive sectors. In the manufacturing process of 3D printed products, it is possible to produce different objects with distinctive filament and powder materials using various production technologies. AM covers several 3D printing techniques such as fused deposition modeling (FDM), inkjet printing, selective laser melting (SLM), and stereolithography (SLA). The present review provides an extensive overview of the recent progress in 3D printing methods for electrochemical fields. A detailed review of polymeric and metallic 3D printing materials and their corresponding printing methods for electrodes is also presented. Finally, this paper comprehensively discusses the main benefits and the drawbacks of electrode production from AM methods for energy conversion systems.

In this study, polylactic acid (PLA) composites containing different ratios (5%–15%) of graphene (GRP) and carbon nanofiber (CNF) were filamented using an extruder and then, 3D printed electrodes were produced by fused deposition modeling (FDM) method using the obtained GRP‐PLA and CNF‐PLA based filaments. The Electrochemical measurements of the 3D electrodes toward the hydrogen evolution reaction (HER) were investigated. According to the results obtained from the cathodic curves; It was determined that the current densities of 15% GRP/PLA and 15% CNF/PLA 3D electrodes were higher than the other electrodes and these values were around 0.325 and 0.329 mA cm−2, respectively. From the EIS results, the resistance values (Rct + Rad) for 15% GRP/PLA and 15% CNF/PLA 3D electrodes were found to be around 1465 and 9135 Ω cm2, respectively. It was determined that these two 3D electrodes had the lowest resistance values compared to other ratios. To increase the efficiency for HER, after soaking in 1 M KOH for 1 h, the activation process was carried out using the CV method by taking 100 cycles in the 0/−3 V range. The results were compared with the activation method reported in the literature (DMF and 2.5 V electrochemical treatment).

Additive manufacturing (AM) is pivotal in modern manufacturing, allowing diverse materials to create functional parts. Polymer composites, with superior properties like enhanced mechanics and conductivity, are highly regarded. Fused deposition modeling (FDM) is a favored, cost‐effective AM technique. Despite popularity, FDM struggles with poor surface quality, impacting final part properties. This challenge affects composite part performance, prompting a need for surface quality enhancements in AM processes, like FDM. The review explores essential post‐treatments required to optimize composite parts for various applications. It examines surface finishing techniques for FDM 3D printed polymeric composites, categorizing them into chemical, thermal, and physical methods. Recent research is extensively analyzed, offering a comprehensive guide for academia and industry. The review covers diverse aspects, including properties, surface morphology, electrical conductivity, and mechanical properties pre‐ and post‐finishing methods. Additionally, it summarizes leading companies worldwide providing surface finishing services for 3D printed polymer parts. Discussions on future trends, challenges, and research gaps in this field are included, emphasizing its significance in refining surface finishing methods for FDM 3D‐printed polymeric composites and encouraging broader industrial adoption of AM. This overview serves as a crucial roadmap for engineers, scientists, customers, and companies interested in surface finishing services.
