Compared to traditional production methods, 3D printing (3DP) by material extrusion has many advantages, such as fast and flexible design, the possibility of prototyping, mass customisation, innovation in business models, and environmental friendliness through waste reduction and recycling . One of the most promising implementations of 3DP in electrochemistry concerns sensing , where the number of reports and citations is growing exponentially, see Fig. . 3D-printable sensors offer a promising approach for rapid, cost-efficient, and customisable monitoring of chemicals in environmental and biological matrices. They thus could play a crucial role in addressing concerns related to potential health and ecological impacts by enabling rapid on-site analysis and early intervention. 3DP electrodes have been used to detect trinitrotoluene , tetracycline , dopamine , and caffeine , and much more. However, only a few available reports focus on pharmaceutical diagnostics , usually reaching micromolar detection limits.
