对于MFC技术的实际应用，应该针对特定的目标用途对设计以及制造和组装过程进行优化。另一项新兴技术--加法制造(3D打印)--通过提供高度的设计自由度，可以为这种方法做出重大贡献。在这项研究中，我们研究了商业上可用的3D可打印聚合物材料作为MFC膜和阳极的使用。性能最好的膜材料凝胶-莱膜材料产生的最大功率为240x±11nμW，是对照CEM的1.4倍，pmax为177x±229fμW。在补料分批循环中，凝胶材料(133.8-184.6μW)的峰值功率值也高于对照组(133.4-160.5μW)。在材料成本方面，测试的膜略高于对照CEM，主要是因为采购量较小。最后，第一个3D可打印聚合物阳极，一种导电的聚乳酸材料，显示出作为低成本和易于制造的MFC阳极的巨大潜力，尽管导电性较差且单位体积的表面积相对较小，但仍能产生稳定的功率输出水平。这些结果证明了以相对较低的成本用单独优化的元件制造单片MFC的实用性。
For practical applications of the MFC technology, the design as well as the processes of manufacturing and assembly, should be optimised for the specific target use. Another burgeoning technology, additive manufacturing (3D printing), can contribute significantly to this approach by offering a high degree of design freedom. In this study, we investigated the use of commercially available 3D printable polymer materials as the MFC membrane and anode. The best performing membrane material, Gel-Lay, produced a maximum power of 240 ± 11 μW, which was 1.4-fold higher than the control CEM with PMAXof 177 ± 29 μW. Peak power values of Gel-Lay (133.8–184.6 μW) during fed-batch cycles were also higher than the control (133.4–160.5 μW). In terms of material cost, the tested membranes were slightly higher than the control CEM, primarily due to the small purchased quantity. Finally, the first 3D printable polymer anode, a conductive PLA material, showed significant potential as a low-cost and easy to fabricate MFC anode, producing a stable level of power output, despite poor conductivity and relatively small surface area per unit volume. These results demonstrate the practicality of monolithic MFC fabrication with individually optimised components at relatively low cost.
