“…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, [47–49] devices for electrochemical energy‐storage and conversion, [50,51] and sensors [52,53] . In this review, we highlight the fundamental role of 3D printing techniques in the design and fabrication of advanced architectures of electrochemical devices, and some reported works on 3D printing in different fields of electrochemistry are shown in Figure 2.…”
