Step by Step Guide to Change the Filaments

Here's a step-by-step guide to changing filaments during a 3D print:

Pause the Print

Initiating a filament change begins with pause print to change filament, which can typically be done directly from your printer’s control panel. Adjust the bed and nozzle temperatures as necessary—lower the temperature for the current filament or increase it for the new filament, especially if it requires higher print temperatures.

Retract the Filament

Next, retract the filament from the extruder. For AnkerMake 3D printers, click the "Retract" button, and consider a retraction length suitable for your specific printer and filament type. It’s crucial to retract it sufficiently to avoid any clogging or jamming issues, ensuring a smooth change filament during print process.


Remove the Old Filament

After retracting, carefully remove the old filament. Handle this step delicately to avoid damaging the extruder or filament feeder.


Load the New Filament

Now, it's time to load the new filament. This could be a different color or type of filament, such as switching from PLA to ABS. It’s important to make sure that the new filament is properly aligned and fed into the printer. If you are using our AnkerMake 3D printer, it is advised to cut the filament head at a 45° angle. This will make it easier to put into the printer.



Before resuming the print, perform a 'purge' by extruding some of the new filament. This step helps flush out any remaining old filament from the nozzle, ensuring a clean transition. Extrude enough filament to see a consistent flow of the new material, confirming that the old filament is completely cleared from the system.


Resume the Print

Once the new filament is loaded, resume printing. Keep in mind that while the printer should resume from where it paused, there might be minor imperfections or color variations in the print area where the filament change occurred. Post-processing or adjustments may be needed based on the print's specifications.


Tips for Changing Filaments During the Print

Changing filament mid print is a crucial skill in 3D printing, requiring meticulous attention to detail to ensure a smooth transition. Here's how you can master this task:
  1. Compatibility Check: Before making any changes, confirm that the new 3D printer filaments are compatible with your printer and the filament you were previously using. This is especially important when switching between different types. Adjust your printer settings to accommodate the new filament's requirements.
  1. Preparation: To reduce downtime and the risk of print errors, prepare the new filament before pausing the print. This step is crucial for a smooth changeover.
  1. Temperature Considerations: Different materials require different temperature settings due to their varying melting points. For instance, PLA generally prints at around 190°C to 220°C, while ABS needs a higher range of approximately 220°C to 250°C.
  1. Clean Transition: Before inserting the new filament, ensure that the extruder is free from any residue of the previous filament. This prevents issues like color mixing or blockages, ensuring a clean transition.
  1. Firm Installation: It's essential to install the new filament firmly. A loose installation can cause uneven printing or extrusion errors, compromising the quality of your print.
  1. Test Extrusion: Conduct a brief test extrusion before resuming the print to confirm that the new filament is flowing correctly. This step verifies that the printer is ready to continue with the new material.



Learning how to change 3D printer filament mid-print is a valuable skill. Whether you need to change filament during print due to it running out or you're looking to add a splash of color, these steps will help you achieve a seamless transition without disrupting your print. Practice plays a crucial role in honing this skill, empowering you to better understand your printer's functionality and optimize your designs. By embracing these techniques, you can fully leverage the diverse color options available in filament and unlock endless possibilities for your creations. Don't hesitate to experiment—your next remarkable masterpiece might just be a filament change away!


Frequently Asked Questions About “How to Change Filament Mid Print?”

What to Do When Filament Runs Out Mid Print?

If you run out of filament during printing, simply pause the print, replace the spool, and resume the printing process. Additionally, an external filament monitor can be used to automatically pause the print when the filament runs out.


Can I Change Filament Mid-Print with Different Types of Filaments, Such As PLA to ABS?

Yes, you can change filament while printing with different types. However, ensure that your printer supports the new filament type and adjust the temperature settings accordingly for a smooth transition.


How Do I Ensure a Smooth Transition between Filaments?

To ensure a smooth transition, pause the print to change filament carefully, and make sure the new filament is properly loaded and extruding smoothly before resuming the print. Additionally, regular maintenance of your printer also helps in achieving better results.
