This manuscript investigates the chemical and structural stability of 3D printing materials (3DPMs) frequently used in electrochemistry. Four 3D printing materials were studied: Clear photopolymer, Elastic photopolymer, PET filament, and PLA filament. Their stability, solubility, structural changes, flexibility, hardness, and color changes were investigated after exposure to selected organic solvents and supporting electrolytes. Furthermore, the available potential windows and behavior of redox probes in selected supporting electrolytes were investigated before and after the exposure of the 3D-printed objects to the electrolytes at various working electrodes. Possible electrochemically active interferences with an origin from the 3DPMs were also monitored to provide a comprehensive outline for the use of 3DPMs in electrochemical platform manufacturing.
本手稿研究了电化学中常用的四种 3D 打印材料（3DPMs）的化学和结构稳定性：Clear photopolymer、Elastic photopolymer、PET 细丝和 PLA 细丝。研究了它们在暴露于选定有机溶剂和支持电解质后的稳定性、溶解度、结构变化、柔韧性、硬度和颜色变化。此外，还研究了在将 3D 打印物体暴露于各种工作电极的电解质前后，选定支持电解质中可用的潜在窗口和氧化还原探针的行为。还监测了可能来自 3DPM 的电化学活性干扰，以提供在电化学平台制造中使用 3DPM 的综合概述。
