The EX2 Extruder Setup enables you to profit from evolution in plastic recycling and make clever use of industrial plastics. In essence, it is a small-scale solution to a big environmental problem making sustainable manufacturing possible for a larger audience, not only those with expert knowledge. This closed loop system is an example of sophisticated engineering - our specialists managed to downsize an entire filament production line into three elements: EX2 Extruder, Airpath, and Spooler. This bundle is a full setup that includes everything that is needed to develop and produce filament for any FDM or FFF 3D printer.
The EX2 Extruder is our entry-level extrusion system, designed to be simple for those who are just starting to make filament. The EX2 features a compact three-stage extrusion screw made from hardened and polished high-carbon stainless steel. This proprietary, patent-pending screw is designed to pressurize plastic during the extrusion process, assisting in diameter control and boosting the overall output. The mixing capability of the screw is enhanced by the utilization of a progressive compression section, which applies shear force between the polymer and the barrel wall. The EX2 also features extrusion speed control. The speed control board includes an automatic, variable voltage control module that is engineered to regulate the precise RPM of the screw as forces fluctuate in the extrusion process. When used with the Spooler, tolerances of +/-0.05mm can be achieved at a rate of 2 lbs an hour.
The Airpath uses forced convection to cool filament as it is being extruded. The Spooler can be used for the common ABS and PLA materials to help get greater tolerance and easier extrusion setup. The air path is a must for researchers and development labs who are working with higher temperature polymers where the filament needs to be cooled before it is passed through the Spooler. This system has a speed readout so that consistent speeds can be set.
The Spooler is the ultimate compliment to our extruder systems. In addition to conveniently spooling your extruded filament, the unit allows you to easily fine-tune the extrusion diameter for the tightest possible tolerances. This is achieved by adjusting the speed of the puller wheels, which draw the filament from the extruder. The puller wheels have been engineered to be non-compressive, meaning they preserve the quality of the extrusion. This updated model features a variable traverse mechanism to evenly distribute filament onto the spool, an upgraded circuit board for the smoothest possible power delivery, and stainless roller shafts which glide on sealed bearings.
