In recent years, the use of additive manufacturing (AM) has been demonstrated in the fabrication of components in polymer electrolyte membrane fuel cell, solid oxide fuel cell (SOFC), microbial fuel cell (MFC) and laminar flow-based fuel cell (LFFC). Various AM technologies have been successfully demonstrated in fuel cell manufacturing include material extrusion, powder bed fusion, vat photopolymerization and binder jetting. One of the unique advantages of AM is the ability to handle sophisticated design with features ranging from macro to micro scales, which are inaccessible by conventional manufacturing technologies. Well-designed complex 3D structures were reported to have the potential for increasing the performance of fuel cells. Therefore, AM presents itself as a promising fabrication method to promote the development of fuel cells. Besides, AM also showed its specialty in time-saving, flexibility, and on-demand manufacturability in the fabrication of fuel cell components. In spite of the prospects of AM in fuel cells, more studies and researches are required to overcome challenges, such as availability of material, manufacturing quality, and the costs. This review focuses on the advantages and applications of additive manufacturing that enable improvement in fuel cell performance. The critical challenges and directions for future development are also highlighted.

“…In 2013, Comina et al published a paper in which they used 3D printed templates which were fabricated by a DLP 3D printer for glucose sensing [3]. PDMS casting and characterizing the roughness of 3D printing has been demonstrated in a report by Bonyar et al [4] and new method for fabricating helical channels by 3D printing the structure, casting PDMS around it and removing the structure from the molds was used by Hwang et al [5]. In this research, a microfluidic device for cell stimulation was achieved by 3D printed templates [6].…”

-The application of channels with multiple thicknesses is a major area of interest within fields of tissue engineering and microfluidics. 3D printing facilitates cost-effective fabrication of PDMS-based microfluidics using 3D printed molds. In this work, the limitations and the accuracy of using 3D printed templates for microfluidic applications with commercial SLA and FDM 3D printers, are presented. A 3D microfluidic cell culturing device that contains multiple thicknesses is proposed and the accuracy of printed parts in three dimensions is demonstrated. The reusable molds can be printed in less than two hours, with the average cost of 0.35 US$, which lead to fast and cheap fabrication compared to conventional fabrication methods which require clean room facilities. The surface roughness of these 3D printed molds are 0.25 and 1.12 for flexible and clear resins.

“…The rapid prototyping nature of this technology also offers an affordable means to enabling agile iterative design and optimization. Components of microfluidic devices and integrated functional platforms have been fabricated using various commercialized 3D printing techniques, i.e., stereolithography, digital micromirror device-based projection printing, two-photon polymerization, fused deposition modeling (FDM), inkjet, and bioprinting [7][8][9][10][11][12][13][14][15][16][17]. A variety of biomedical fluidic devices have been developed using 3D printing technologies [7,8,17].…”

Polydimethylsiloxane (PDMS)-based casting method was used to fabricate PDMS cell culture platforms with molds printed by a fused deposition modeling (FDM) printer. Cell viability study indicated that the produced plates have the suitable biocompatibility, surface properties, and transparency for cell culture purposes. The molds printed from acrylonitrile-butadiene-syrene (ABS) were reusable after curing at 65 °C, but were damaged at 75 °C. To understand thermal damage to the mold at elevated temperatures, the temperature distribution in an ABS mold during the curing process was predicted using a model that considers conduction, convection, and radiation in the oven. The simulated temperature distribution was consistent with the observed mold deformation. As the maximum temperature difference in the mold did not change appreciably with the curing temperature, we consider that the thermal damage is due to the porous structure that increases the thermal expansion coefficient of the printed material. Our study demonstrated that FDM, an affordable and accessible three-dimensional (3D) printer, has great potential for rapid prototyping of custom-designed cell culture devices for biomedical research.
