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. <b>Tools used:</b> PLA filament: https://www.banggood.com/Creality-3D-White-or-Black-or-Yellow-or-Blue-or-Red-1KG-1_75mm-PLA-Filament-For-3D-Printer-p-1290153.html?p=E01411629100201406T1&custlinkid=926158 FLsun Super Racer: https://www.banggood.com/custlink/GGKYBGkYhZ <b>Feel free to take a look at my other designs:</b> Turning 50 cent into a Bitcoin: https://www.thingiverse.com/thing:4705186 3D printable antweight battlebot: Bulldog: https://www.thingiverse.com/thing:4623536 SpaceX inspired edf rocket: https://www.thingiverse.com/thing:4606751 3D printed high torque servo/gearbox version 2: https://www.thingiverse.com/thing:4547703 UMC - Universal motion controller: https://www.thingiverse.com/thing:4245315 3D-printable Davinci catapult gift card: https://www.thingiverse.com/thing:4067668 Arduino controlled photogrammetry 3D-scanner: https://www.thingiverse.com/thing:3958326 Fully 3D-printable turntable: https://www.thingiverse.com/thing:3723618 RC FPV tank rover: https://www.thingiverse.com/thing:3587738 Fully 3D-printable wind-up car gift card: https://bbprojects.technology/collections/stl-fusion-360-source-files/products/fully-3d-printable-wind-up-car-gift-card-files 3D-printable High torque servo/gear reduction: https://www.thingiverse.com/thing:3292860 'BOOM box' high voltage capacitor bank case: https://www.thingiverse.com/thing:2980012 Subby the interactive youtube subscriber robot: https://www.thingiverse.com/thing:2928254 robot hand || bionic hand prosthesis prototype: https://www.thingiverse.com/thing:2838239 3D-printable linear actuator: https://www.thingiverse.com/thing:2783959 Mini 3D-printable crossbow: https://www.thingiverse.com/thing:2710472 8 legged spider robot: https://www.thingiverse.com/thing:2470882 best 3D-printable bearing: https://www.thingiverse.com/thing:2349065 Have a nice day!
