This work introduces a novel approach for fabricating purposeful robots using 3D printers. Simultaneously depositing photopolymers and a non-curing liquid allows complex, pre-filled fluidic channels to be fabricated. This new printing capability permits complicated hydraulically actuated robots and robotic factors to be robotically built, with no meeting required. The method is showcased by using printing linear bellows actuators, equipment pumps, tender grippers and a hexapod robot, the usage of a commercially-available 3D printer. We element the steps required to modify the printer and describe the sketch constraints imposed by using this new fabrication approach.
