消费级熔丝制造（FFF）3D打印机用于构建用于纳米颗粒制备和电化学传感的流体装置。器械使用聚对苯二甲酸乙二醇酯打印，并具有螺纹端口，通过由丙烯腈丁二烯苯乙烯（ABS）制备的打印接头连接聚醚醚酮（PEEK）管路。这些装置包括设计为具有800 × 800 µm2正方形横截面的通道，并且是半透明的，以允许溶液填充通道的可视化。使用具有Y形混合通道的3D打印设备在100至2000 µL min−1的流速下制备普鲁士蓝纳米颗粒（PBNP）。然后将PBNP附着到金电极上用于过氧化氢传感。用于电化学测量的3D打印设备具有螺纹接入端口，其中可以插入配备有参考，计数器和PBNP修饰的工作电极的配件。PBNP修饰的电极通过流动注射分析实现了3D打印通道中H2O2的安培检测，检测限为100 nM，线性响应高达20 µM。这些实验表明，消费级FFF打印机可用于制造低成本的流体设备，其应用类似于使用更昂贵的3D打印方法报道的应用。
A consumer-grade fused filament fabrication (FFF) 3D printer was used to construct fluidic devices for nanoparticle preparation and electrochemical sensing. Devices were printed using poly(ethylene terephthalate) and featured threaded ports to connect polyetheretherketone (PEEK) tubing via printed fittings prepared from acrylonitrile butadiene styrene (ABS). These devices included channels designed to have 800 × 800 µm2 square cross sections and were semitransparent to allow visualization of the solution-filled channels. A 3D-printed device with a Y-shaped mixing channel was used to prepare Prussian blue nanoparticles (PBNPs) under flow rates of 100 to 2000 µL min−1. PBNPs were then attached to gold electrodes for hydrogen peroxide sensing. 3D-printed devices used for electrochemical measurements featured threaded access ports into which a fitting equipped with reference, counter, and PBNP-modified working electrodes could be inserted. PBNP-modified electrodes enabled amperometric detection of H2O2 in the 3D-printed channel by flow-injection analysis, exhibiting a detection limit of 100 nM and linear response up to 20 µM. These experiments show that a consumer-grade FFF printer can be used to fabricate low-cost fluidic devices for applications similar to those that have been reported with more expensive 3D-printing methods.
