Additive manufacturing (3D printing), particularly fused deposition modeling (FDM), has rapidly advanced, offering customized designs, reduced waste, lower costs, and fast prototyping for electroanalytical applications. Herein, the electrochemical secnidazole (SCZ) behavior was studied using additive manufactured electrodes (AMEs) based on commercial carbon black polylactic acid (PLA) conductive filament. Before use, AMEs were submitted to electrochemical/chemical activation (+1.4 V -1.0 V, both 200 s) in basic medium (0.5 mol L-1 NaOH). Under optimized square wave voltammetry (SWV) conditions 0.12 Britton Robinson buffer (pH = 2.0) as supporting electrolyte, SCZ exhibited excellent linearity within concentration range of 2.5 250.0 μmol (R2 0.998). The proposed method successfully applied detect quantify pharmaceutical seized samples. obtained results statistically similar (95% confidence level) values by HPLC. These findings demonstrate that 3D-printed developed this study provide a cost-effective, facile, highly sensitive platform on-site analysis, presenting significant potential future forensic

Additive manufacturing (AM) has emerged as a transformative technology for producing complex, high-performance components across industries such aerospace, healthcare, and automotive. Central to enhancing the precision, reliability, scalability of AM is integration advanced sensors real-time monitoring systems. These technologies enable in-situ process control, early defect detection, adaptive feedback mechanisms that elevate both production quality efficiency. This chapter delves into diverse roles sensor technologies—including thermal, optical, force, gas, acoustic sensors—and how their deployment facilitates intelligent decision-making through machine learning artificial intelligence. In addition, we discuss real time data analytics computational modeling are being used predict control outcomes move away from reactive predictive. The growing relevance hybrid manufacturing, which combines additive subtractive processes also examined its high precision applications.
