This is a stepper paste extruder in bowden style. It is ment to be used with a silicon tube(6mm OD) and bowden connector(PC6-M6) in the front.

The silicone tube leads to the printhead made out of anything you want(needle, silicone cap..)

The tube that is the main part of the extruder is a PVC pipe(50mm OD and 1.8mm thick walls)

soon to be replaced with food grade INOX pipe of the same size.

Il be making a printing head for the Printrbot simple metal.
