5500 ml Linear actuator Ram


5500 ml Linear actuator Ram


Linear actuator RAM only. This is an ideal option if you already have an existing 3D Printer. RAM can be adapted to almost any style of machine.

We have recently developed a large new system for large scale delivery of paste. This linear actuator RAM is fully controllable from within the standard 3D printer control software. You can change and control the flow rate as the print is printing.  Utilizing the larger capacity 5500ml and the extremely robust components our extruder is able to flow at much higher rates then most others. 
In a commercial application this gives you the ability to produce your product at a higher cycle time. During the design and construction of our RAM we paid particular attention to easy disassembly and cleaning. Everything is constructed with food grade materials for safe food handling.  Specifically designed for thicker materials like heavy clay, thick dough, and confectionery products. The larger volume capacity is also suited for less frequent loading and bigger extrusions.

ClearPath® - Integrated Servo System

These are incredibly quiet, very efficient, and extremely fast.


Our large capacity 5500 ml extruder holds approximately 24 lb of clay. This extruder is specifically designed for large-scale vessels or projects that need continuous extrusion without reloading. It is also ideal for production environment as down-time will be kept at a minimum. The extruder is constructed from high-grade precision CNC parts with heavy American-made Acme screw. The drive mechanism consists of a robust gearbox and DC servo motor. This motor is extremely sophisticated and have many advantages compared to just a plain stepper motor. The servos have a full on board diagnostics which can be analyzed real time on your laptop.

This new extruder can be driven with any standard 3D printer controller board that produces pulse, step, and direction signals.

We also have an optional stand alone touchscreen and controller board.

Included is a very robust power supply to handle the heavy loads that this motor is capable of delivering. 

The 5500 ml extruder also has all of the same features our smaller 2000 ml extruder has including easy disassembling and cleaning. 

The extruder can be utilized in several different configurations: 




5500 ml extruder comes with 1  3.75 diameter poly-carbonate/carbon reinforced tube.

Extruder drive motor is state-of-the-art DC servo with integrated drivers.

Power requirements 75 volts input 110/220 volts, 60/50 Hertz

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

Overall dimensions when fully loaded 94 inches from nozzle to top of Acme screw (installed on 3DP 7XXL machine).

Overall empty weight: 15 lbs (Fully loaded: +35 lbs)


Mounting application


Use one of our smaller machines like the 3D PotterBot 3DP-7 and have a direct connection from the Z-axis arm via hose assembly to the horizontally positioned 5500ml extruder. 


Scara arm robot holding it directly with the robotic arm and either utilizing our controller or on-board step controller.


Use your own 3D printer with the hose assembly, just be aware that the hose is almost 0.75" diameter and does present a resistance to your printer mechanism.
