Impressão 3D (Manufatura Aditiva) Aplicada à Química Eletroanalítica

Resumo

3D printing, also known as additive manufacturing, has transformed various fields of science, especially Analytical Chemistry. This innovative technology presents advantages such as low cost, reproducibility in printing, large-scale production capacity, and design flexibility in device manufacturing. Currently, 3D printing has been widely adopted in Electroanalytics, bringing significant innovations in the production of electrochemical sensors. In this context, this work explores and details relevant information about 3D printing in the development of electrochemical sensors, with an emphasis on Fused Deposition Modeling (FDM) and its advantages, as well as the main challenges faced and strategies used to overcome the limitations of this technique. Relevant topics such as the filaments used, the optimization of printing parameters, the surface pretreatment of electrodes, and the implementation of modifications on these surfaces are addressed. To deepen these issues, examples of electrochemical sensors are presented that highlight the applications of this technology in various areas, underscoring the potential of 3D printing in the field of Electroanalytics.
