Water Cooling - Hot Environment Ready
The RD-M25 is able to operate in any environmental condition. The water-cooling loop keeps the whole system (motor, screw shank, reducer and feeding zone) at a constant temperature.
4 Zone Heating Barrel Control
The quadruple heat zone design helps to keep the polymer at a constant temperature. The feeding section receives cold pellets and generates more heat to melt them. Then, the compression zone stabilizes the polymer at a precise temperature ensuring the plastification process (all the solid pellets turn into a molten status). Finally, the metering heater ensures an even flow.
Multiple Nozzle Size
RD-M25 can be used with large nozzles from 3.00mm up to 12.00mm. They can also be customized.
Customized Extrusion Screw
The bimetallic customized screw design is optimized for high-resolution 3D printing. Two tapered bearings, which support the screw, allow a low friction rotation, a bore centering of the screw in the barrel and can handle the whole high axial force required to extrude in high-speed and pressure conditions.
Melting Zone Sensor
The temperature sensors are placed only 0,5 mm away from the molten polymer. Readings are reliable and accurate.
Precise Temperature Control
The four K-type thermocouple sensors are class 1, high precision sensors. The circuit has been designed to use the best resolution between 20°C and 500°C.
Powerful 2kW SERVO Motor
The powerful 2kW Geared SERVO MOTOR can handle high flow without any strain. To maximize RD-M25 extruder’s compatibility, the motor driver can accept step and direction signals, 0-10V, EtherCAT, CANopen or RS-485 as communication protocols.
The fast speed of RD-M25 is managed by a breaker. Like the faucet filter does with the water, the breaker aligns the output flow in order to avoid the spiral effect created by high-speed.
The spiral heaters wrap the whole heated barrel and ensure uniform temperature along the whole length end of the extruder.
A special insulation blanket is used to coat the Cylinder, in order to keep the heat inside and save the energy required to reach the temperature setpoints.
