  The current fabrication and assembly of fluidic circuits for soft robots
relies heavily on manual processes; as the complexity of fluidic circuits
increases, manual assembly becomes increasingly arduous, error-prone, and
timeconsuming. We introduce a software tool that generates printable fluidic
networks automatically. We provide a library of fluidic logic elements that are
easily 3D printed from thermoplastic polyurethanes using Fused Deposition
Modeling only. Our software tool and component library allow the development of
arbitrary soft digital circuits. We demonstrate a variable frequency ring
oscillator and a full adder. The simplicity of our approach using FDM printers
only, democratizes fluidic circuit implementation beyond specialized
laboratories. Our software is available on GitHub
(https://github.com/roboticmaterialsgroup/FluidLogic).
