Introduction To Replicator 2X And Its Extruder System
The Replicator 2X by MakerBot is a dual-extruder 3D printer, meaning it can handle two filaments at once, giving users more flexibility for complex prints. Whether you want to print objects with different colors, or you need support material for overhangs, the ability to change the extruder settings is a key feature.
The dual extrusion system is designed to allow two filaments to be loaded simultaneously, with one extruder typically used for the primary material, and the other used for support or a secondary material. You can also print in dual colors or experiment with different combinations of filaments.
Understanding how to change the material and adjust the extruder settings is crucial in maximizing your 3D printer’s performance.
Why Change The Extruder Settings Or Filament?
Changing the extruder settings or filament type on your Replicator 2X opens up new possibilities. Here’s why you might want to change it:
- Different filament types: Not all filaments work the same way. PLA, ABS, and Nylon each have unique properties, requiring different temperatures and extrusion speeds.
- Specialty filaments: You might want to use filaments with unique properties, such as flexible, carbon fiber-infused, or high-temperature materials.
- Improved print quality: Switching filaments can improve your print results, whether you want smoother finishes or more durable parts.
- Experimentation: By changing filaments, you can explore creative possibilities with mixed material prints.
Steps To Change The Filament On Replicator 2X
Changing the extruder settings or filament on the Replicator 2X is an easy process, and it can be done in a few simple steps.
Prepare the Printer
Before making any changes to the extruder or filament, it’s essential to ensure your printer is properly prepared:
- Turn off the printer: Always start by turning off your 3D printer for safety.
- Check the extruder heads: Confirm that both extruder heads are free from obstructions, as old filament or debris can affect performance.
- Choose the filament: Decide on the filament you want to use. Different materials (e.g., PLA, ABS, or Nylon) have different temperature requirements.
Unload Old Filament
Once your printer is ready, follow these steps to unload the old filament from the extruder:
Turn the printer back on and access the LCD screen.
Navigate to the “Filament” menu, then choose the “Unload” option.
The extruder will heat up to the appropriate temperature based on the material. Wait until the extruder has reached the required temperature (check the Filament Settings for guidance).
Once the extruder is heated, the system will retract the filament automatically.
Gently pull the filament out of the extruder if necessary.
Load New Filament
Now that the old filament has been unloaded, it’s time to load your new filament. Follow these steps:
Prepare the new filament: Make sure the filament is cut cleanly and is free of tangles.
Insert the filament into the filament guide tube leading to the extruder.
Navigate to the “Filament” menu on the LCD and select “Load”.
The printer will heat the extruder and start feeding the filament into the nozzle.
Once you see the filament coming out of the nozzle, you’re ready to begin printing with your new material.
Adjusting Extruder Settings For Specific Filaments
Different types of filaments require different extruder settings. To ensure optimal performance, adjust the temperature and speed settings accordingly.
PLA Filament:
- Extruder temperature: 190-210°C
- Print bed temperature: 50-60°C
- Print speed: Moderate (50-60mm/s)
ABS Filament:
- Extruder temperature: 220-250°C
- Print bed temperature: 90-110°C
- Print speed: Moderate to fast (60-80mm/s)
Nylon Filament:
- Extruder temperature: 240-260°C
- Print bed temperature: 80-100°C
- Print speed: Slow to moderate (40-60mm/s)
It’s essential to adjust these settings based on your filament to avoid issues like warping, poor adhesion, or clogs.
Troubleshooting Common Extruder Problems
Changing filament might sometimes lead to issues. Here are some common problems and their solutions:
Clogs:
- Cause: Filament buildup or incorrect temperature.
- Solution: Try cold pulling—heat the nozzle, then let it cool down to remove the blockage.
Poor adhesion:
- Cause: Bed not properly calibrated or wrong print settings.
- Solution: Level the bed and check that the correct print settings are used for your filament.
Under-extrusion:
- Cause: Insufficient filament or wrong extruder temperature.
- Solution: Make sure the filament spool is feeding correctly and adjust the temperature.
How To Use Advanced Filaments
The Replicator 2X supports a variety of advanced filaments, including:
- Flexible filaments: These are great for creating flexible parts but require slow printing speeds and precise extruder settings.
- Carbon fiber-infused filaments: They are more abrasive and require hardened steel nozzles to prevent wear.
- High-temperature filaments: Filaments like Polycarbonate (PC) or PPSU require higher extrusion and bed temperatures, making them ideal for tough industrial parts.
To use these materials, always check the manufacturer’s recommendations for temperature and speed settings.
Maintaining The Extruder And Printer
Regular maintenance is vital for keeping your Replicator 2X running smoothly:
- Clean the extruder: Regularly check for filament buildup and clean the nozzle.
- Lubricate moving parts: The rails and other moving parts should be lubricated periodically to avoid wear.
- Calibrate the bed: Ensure the print bed is level and free from debris to maintain good adhesion.
Conclusion
Changing the filament and adjusting the extruder settings on your Replicator 2X is a straightforward process that opens up a world of printing possibilities. Whether you’re switching between PLA, ABS, Nylon, or other specialized materials, taking the time to adjust the printer’s settings will result in higher-quality prints and a more enjoyable 3D printing experience.

FAQs
What is the Replicator 2X and how does it work?
The Replicator 2X is a dual-extruder 3D printer that allows for printing with two filaments at once, enabling users to print multi-color or multi-material objects. It uses Fused Deposition Modeling (FDM) technology to melt and extrude filament through a hot nozzle to build objects layer by layer.
How do I unload filament from the Replicator 2X extruder?
To unload filament, navigate to the Filament menu on the printer’s LCD, select Unload, and allow the extruder to heat up and retract the filament. Gently pull the filament out if needed.
What temperature should I set the Replicator 2X for ABS filament?
For ABS, the extruder temperature should be set between 220-250°C, and the print bed should be heated to 90-110°C.
How can I prevent clogs in the Replicator 2X extruder?
To prevent clogs, ensure you’re using the correct temperature settings for your filament, and regularly clean the extruder nozzle. If a clog occurs, perform a cold pull to clear the nozzle.
Can I use flexible filaments with the Replicator 2X?
Yes, the Replicator 2X can use flexible filaments. However, you’ll need to adjust the print speed and temperature settings, as flexible filaments tend to require slower speeds and different extrusion settings.
