我们提出了一种新型的3D打印多材料微流体比例阀。微流体阀是一个基本的原始，使可编程的，自动化的设备，以精确的方式控制流体的发展。我们讨论了瓣膜表征结果，以及通道宽度、膜厚度和膜刚度的探索性设计变化。与之前的刚性单一材料3D打印阀相比，这些打印阀通过刚性和柔性材料的组合在空间上限制流体变形，以实现致动的功能梯度装置中的复杂几何形状。该研究标志着在一个步骤中向3D打印多属性可编程流体设备的转变，其中集成的多材料阀可用于控制各种应用的复杂流体反应，包括DNA组装和分析，连续采样和传感以及软机器人。
We present a novel 3D printed multimaterial microfluidic proportional valve. The microfluidic valve is a fundamental primitive that enables the development of programmable, automated devices for controlling fluids in a precise manner. We discuss valve characterization results, as well as exploratory design variations in channel width, membrane thickness, and membrane stiffness. Compared to previous single material 3D printed valves that are stiff, these printed valves constrain fluidic deformation spatially, through combinations of stiff and flexible materials, to enable intricate geometries in an actuated, functionally graded device. Research presented marks a shift towards 3D printing multi-property programmable fluidic devices in a single step, in which integrated multimaterial valves can be used to control complex fluidic reactions for a variety of applications, including DNA assembly and analysis, continuous sampling and sensing, and soft robotics.
