Abstract

Abstract A low-cost 3D-printing system is reported for the deposition of thin films by a dip-coating technique. The structure was constructed using 3D-printed pieces of polylactic acid (PLA) joined by simple snap-fit. This structure assembly and design simplifies the construction and replicability of dip-coating equipment. The components used are affordable and accessible, reducing the cost of implementation. An Arduino controls the system through a C++ program that varies the pulling and dipping speed from 0.5 to 20 mm/s. The pulling and dipping process uses a servomotor motion transformed into linear by a rack and pinion mechanism. The performance of the presented system was validated by comparison of thin-film reduced graphene oxide (rGO) deposition onto gold. The rGO thin films obtained were homogeneous and smooth, capable of being used as electrodes in biosensors.

低成本3D打印系统，用于通过浸涂沉积还原氧化石墨烯（rGO）薄膜，并应用于电极制造

摘要报道了一种低成本的3D打印系统，用于通过浸涂技术沉积薄膜。该结构使用3D打印的聚乳酸（PLA）片通过简单的卡扣配合连接而成。这种结构组装和设计简化了浸涂设备的结构和可复制性。所使用的组件价格合理且易于使用，从而降低了实施成本。Arduino通过C++程序控制系统，该程序将拉伸和浸渍速度从0.5变为20 mm/s。拉伸和浸渍过程使用伺服电机运动，该运动通过齿条和小齿轮机构转换为线性。通过比较薄膜还原氧化石墨烯（rGO）在金上的沉积，验证了所提出的系统的性能。所获得的rGO薄膜均匀光滑，能够用作生物传感器中的电极。

期刊介绍： Instrumentation Science & Technology is an internationally acclaimed forum for fast publication of critical, peer reviewed manuscripts dealing with innovative instrument design and applications in chemistry, physics biotechnology and environmental science. Particular attention is given to state-of-the-art developments and their rapid communication to the scientific community. Emphasis is on modern instrumental concepts, though not exclusively, including detectors, sensors, data acquisition and processing, instrument control, chromatography, electrochemistry, spectroscopy of all types, electrophoresis, radiometry, relaxation methods, thermal analysis, physical property measurements, surface physics, membrane technology, microcomputer design, chip-based processes, and more. Readership includes everyone who uses instrumental techniques to conduct their research and development. They are chemists (organic, inorganic, physical, analytical, nuclear, quality control) biochemists, biotechnologists, engineers, and physicists in all of the instrumental disciplines mentioned above, in both the laboratory and chemical production environments. The journal is an important resource of instrument design and applications data.
