I was wondering if it would be possible to build a fully 3D-printable hydraulic system that's watertight and can be used for robotics. This double helical gear pump is the first component of the fully 3D-printable hydraulic system. Note: The pump is watertight when using the 3D-printed lid with seal and seal tensioner. at some point in the video you can see me using a laser cut plexi lid, this one is only used for demo reasons, doesn't have a seal and so obviously leaks.
