Stereolithography 3D printing, although an increasingly used fabrication method for microfluidic chips, has the main disadvantage of producing monolithic chips in a single material. We propose to incorporate during printing various objects using a “print-pause-print” strategy. Here, we demonstrate that this novel approach can be used to incorporate glass slides, hydrosoluble films, paper pads, steel balls, elastic or nanoporous membranes and silicon-based microdevices, in order to add microfluidic functionalities as diverse as valves, fluidic diodes, shallow chambers, imaging windows for bacteria tracking, storage of reagents, blue energy harvesting or filters for cell capture and culture.

使用“打印-暂停-打印”策略在立体光刻 3D 打印微流体中进行功能集成



立体光刻 3D 打印虽然越来越多地用于微流控芯片的制造方法,但其主要缺点是用单一材料生产单片芯片。我们建议在打印过程中使用“打印-暂停-打印”策略合并各种对象。在这里,我们证明这种新颖的方法可用于合并载玻片、水溶性薄膜、纸垫、钢球、弹性或纳米多孔膜和硅基微型器件,以添加多种微流体功能,如阀门、流体二极管、浅层室、用于细菌追踪的成像窗口、试剂存储、蓝色能量收集或用于细胞捕获和培养的过滤器。
