“…In a work developed by Granados-Fernández et al, they demonstrated that it is possible to design and build an electroabsorption unit (Figure 3B) for the capture and subsequent degradation of benzene through SLA 3D printing, integrating two operations that are usually separated, thus saving space, material and simplifying the system. [49] In this case the degradation performance obtained is similar to those reported in the literature, so the innovation is the integration of 2 devices in 1. In terms of fabrication complexity, 3D printing allows to fabricate cylindrical and rectangular pieces at once with [56,67,68] , respectively.…”

“…In the field of electrochemistry, 3D printing has become increasingly useful, facilitating the construction of complex custom electrochemical devices, at reduced prices, with higher performance, versatile, sustainable, and more durable. In particular, 3D printing can be employed to produce electrodes, [45,46] electrochemical cells, [47][48][49] devices for electrochemical energy-storage and conversion, [50,51] and sensors.

An efficient and successful electrochemical process must take place in an electrochemical reactor with an adapted and optimized design that allows superior performance to be achieved. Traditional manufacturing methods have made the task of optimizing and adapting reactors very expensive. However, 3D printing allows prototypes to be built in a very short time and at a very low cost compared to traditional manufacturing techniques. This has caused research into new electrochemical reactors in different laboratories to skyrocket in recent years. The rapid evolution of 3D printing technology, as well as the appearance of new materials, have meant that they can be included in many applications, such as the electrochemical treatment of contaminated water or energy devices, batteries or fuel cells. In this review, the latest advances in the manufacture of electrochemical reactors and the main applications that have made use of them will be presented and critically discussed.

“…However, in the last five years, progress in the development of this technology slowed down, and no relevant challenges were identified except the search for synergistic combinations between electrochemical technology and other technologies looking for the activation of oxidants during the electrolytic process, especially with photochemical and sonochemical technologies. − Also, the search for new applications and the expansion of the possibilities of treating liquid to gaseous waste through electrochemically assisted reactive absorption processes was also set as a new objective, something that has been successfully addressed. − …”

Boron-doped diamond (BDD) electrodes are the most effective and resistant electrodic materials to perform advanced oxidation processes. Having a reactor that can provide adequate hydrodynamic conditions is mandatory to use these electrodes effectively. In this work, the diamond anode electrochemical reactor (E3L-DAER) is designed to fulfill this necessity. Several features are included to improve its efficiency, like conic inlet/outlet, flow enhancers, and a reduced interelectrode gap. The fluid dynamic validation has been performed using computer fluid dynamics (CFD) calculations, residence time distribution (RDT) curves, and mass transfer analysis. The reactor has been made using a threedimensional (3D) printing stereolithography (SLA) technique, which allows us to build chemical-resistant reactors with nonstandard and tailored features in a cheap and fast way. The obtained results demonstrate that the designed reactor has the required fluid dynamics properties to perform reliable BDD electrode studies and applications. Finally, a BDD electrode was used to test the production of different oxidants such as persulfate, peroxophosphate, and chlorine-derived species.

Ecosystems and environments are impacted by atmospheric pollution, which has significant effects on human health and climate. For these reasons, devices for developing portable and low-cost monitoring systems are required to assess human exposure during daily life. In the last decade, the advancements of 3D printing technology have pushed researchers to exploit, in different fields of applications, the advantages offered, such as rapid prototyping and low-cost replication of complex sample treatment devices. In this work, we present the fabrication and testing of 3D printed cartridges based on both commercial photopolymer and a modified version with the intrusion of nano graphite. The air scrubbing performances towards some volatile organic compounds have been investigated, inserting the cartridges into a low-cost monitoring system using a photoionization sensor. In particular, the cartridges were tested in the presence of concentrations of ethanol, benzene, and toluene to evaluate the abatement percentage with and without their use. Although the results have shown that all cartridges abated ethanol and toluene, the abatement of benzene increased 20 times in the case of cartridges based on modified resin with nano graphite. These results could enable their employment to reduce the concentration of interfering compounds in low-cost monitoring systems.
