This new extruder fills in the gap between the 2000 ml extruder which most of our customers have and the high-capacity 5000 ml high performance extruder.
Our 4000ml extruder is driven by a large closed loop hybrid stepper motor  and extra stuff .625" (15.87mm)  Acme screw. This is a much more robust drive system compared to the 2000ml extruders. It's also capable of extruding thicker clay or paste at a much higher rate then the 2000 ml.
Because of the larger tube and the larger tube nozzle it is capable of larger-diameter nozzles up to .5" (12.75mm) . This gives us the ability to extrude higher volumes of clay through large nozzles that we offer with our machines. It's now possible to print at relatively high speeds with nozzles up to 16 mm.

4000 ml extruder comes with one 3.75 diameter poly-carbonate/carbon reinforced tube.

Power requirements 24 volts

Included T-Glass plastic nozzles: 5, 6, and 7 mm. Additional nozzles custom built upon request.

Overall empty weight: 13 lbs (Fully loaded: 26 lbs)
