3D打印为碳热塑性复合材料电化学传感器的制造提供了一种可靠的方法。许多研究已经探索了打印参数对碳热塑性塑料电极电化学活性的影响，但对仪器参数的影响知之甚少，这些参数已被证明会改变3D打印热塑性塑料的结构和机械强度。研究了挤出机温度、喷嘴直径和加热床温度对炭黑/聚乳酸（CB/PLA）电极电化学活性的影响。使用标准氧化还原探针进行循环伏安法和电化学阻抗谱测量。用扫描电子显微镜观察电极表面和电极的横截面。我们发现，使用230°C和240°C的挤出机温度可以提高CB/PLA电极的电化学活性，这是由于表面粗糙度的增加和打印层之间空隙数量的减少。不同3D打印机的喷嘴直径、加热床温度对CB/PLA电极的电化学活性没有影响。然而，高端打印机提供了更好的电极批量再现性。这些发现突出了在使用3D打印制造碳热塑性复合材料电化学传感器时需要考虑的关键仪器参数。
3D printing provides a reliable approach for the manufacture of carbon thermoplastic composite electrochemical sensors. Many studies have explored the impact of printing parameters on the electrochemical activity of carbon thermoplastic electrodes but limited is known about the influence of instrument parameters, which have been shown to alter the structure and mechanical strength of 3D printed thermoplastics. We explored the impact of extruder temperature, nozzle diameter and heated bed temperature on the electrochemical activity of carbon black/poly-lactic acid (CB/PLA) electrodes. Cyclic voltammetry and electrochemical impedance spectroscopy measurements were conducted using standard redox probes. The electrode surface and cross-section of the electrode was visualised using scanning electron microscopy. We found that using extruder temperatures of 230 °C and 240 °C improved the electrochemical activity of CB/PLA electrodes, due to an increase in surface roughness and a reduction in the number of voids in-between print layers. Nozzle diameter, heated bed temperature of different 3D printers did not impact the electrochemical activity of CB/PLA electrodes. However high-end printers provide improved batch reproducibility of electrodes. These findings highlight the key instrument parameters that need to be considered when manufacturing carbon thermoplastic composite electrochemical sensors when using 3D printing.
