2021

View full text Add to dashboard Cite

In recent years, additive manufacturing has gained importance in a wide range of research applications such as medicine, biotechnology, engineering, etc. It has become one of the most innovative and high-performance manufacturing technologies of the moment. This review aims to show and discuss the characteristics of different existing additive manufacturing technologies for the construction of micromixers, which are devices used to mix two or more fluids at microscale. The present manuscript discusses all the choices to be made throughout the printing life cycle of a micromixer in order to achieve a high-quality microdevice. Resolution, precision, materials, and price, amongst other relevant characteristics, are discussed and reviewed in detail for each printing technology. Key information, suggestions, and future prospects are provided for manufacturing of micromixing machines based on the results from this review.

An efficient fluid mixing performance was achieved at the microand milliscale by a new design "Elis" in a wide range of Reynolds numbers. The micromixer is composed of internal walls and circular obstacles inducing three mass-transfer mechanisms: reduction of the diffusion path; change of the flow direction/vortex generation, and split and recombination of streams. The design was proposed and optimized by numerical simulations, allowing its application as micro-or millidevices. The device performance was numerically assessed by computational fluid dynamics (CFD) in the mixing process of two systems (vegetable oil/ethanol, and water/ethanol) for a Reynolds number range of 0.01−100 and also in the biodiesel synthesis for a residence time range of 10− 180 s. High mixing indexes (M = 0.985) were observed for the oil/ethanol system at low Reynolds numbers of 0.01 and 10. The CFD predictions for oil conversion were 91.32% (height of 1000 μm) and 92.22% (height of 2000 μm) for a residence time of 30 s. For the water/ethanol system, higher mixing indexes were 0.93 at Re = 1, increasing to a maximum of 0.99 at Re = 50 and 100. The numerical results demonstrated good performance of Elis as a millidevice, providing mixing efficiencies similar or even higher than microdevices from the literature.

“…The 3D printing can be employed to fabricate a chemical microplant for biodiesel synthesis, including microreactors, flow distributors and mechanical supports [ 49 , 50 , 51 ]. In the separation engineering, 3D printers were used to manufacture distillation and absorption columns, including the development of trays and packs aiming higher specific area internals to enhance the separation [ 52 , 53 ].…”
