Change Filament on Your 3D Printer: A Quick and Easy Guide

Posted by

3D printing has revolutionized the way we create objects and prototypes. With a 3D printer, you can create virtually anything you can imagine, from simple toys to complex machinery. However, one of the most important aspects of 3D printing is changing the filament. Without proper knowledge of how to change the filament, your 3D printing experience can be frustrating and unproductive.

Changing the filament on a 3D printer is a relatively simple process, but it can be daunting if you’ve never done it before. The filament is the material that your 3D printer uses to create the object you’re printing. When you run out of filament, or if you need to switch to a different color or type of filament, you’ll need to change it. In this article, we’ll go over the steps involved in changing the filament on your 3D printer, so you can get back to printing your designs in no time.

Preparing for Filament Change

Before changing the filament on your 3D printer, it is important to prepare for the process. This will ensure that the change goes smoothly and without any issues. Here are the steps you need to follow to prepare for a filament change:

Step 1: Heat the Nozzle

The first step in preparing for a filament change is to heat the nozzle. This will ensure that the old filament is melted and can be easily removed. You should set the temperature of the nozzle to the melting point of the filament you are using. This information can be found on the packaging of the filament or in the user manual of your 3D printer.

Step 2: Unload the Filament

Once the nozzle is heated, you can start unloading the filament. To do this, you need to access the extruder and release the filament. Depending on the type of 3D printer you have, this process may vary. Some printers have a lever that needs to be pressed to release the filament, while others may require you to manually pull the filament out.

Step 3: Cut the Filament

After you have unloaded the old filament, you need to cut it. This will ensure that the new filament is loaded correctly and that there are no issues with the extrusion process. You should cut the filament at a 45-degree angle to ensure that it can be easily loaded into the extruder.

By following these steps, you can prepare for a filament change on your 3D printer. This will ensure that the process goes smoothly and without any issues. Remember to always refer to the user manual of your 3D printer for specific instructions on how to change the filament.

Loading the New Filament

Once you have removed the old filament from your 3D printer, it’s time to load the new filament. Here are the steps to follow:

Step 1: Load the New Filament

First, make sure your 3D printer is turned on and the nozzle is heated to the correct temperature for the new filament. Check the filament spool for the recommended temperature.

Next, cut the end of the new filament at a 45-degree angle to make it easier to feed into the printer. Then, insert the new filament into the extruder and push it through until it reaches the nozzle.

Step 2: Extrude the New Filament

Once the new filament is in place, you need to extrude it to remove any air bubbles and ensure a smooth flow. In your 3D printing software, find the option to extrude filament and push the new filament through until it comes out of the nozzle.

Step 3: Test the Extrusion

Finally, it’s important to test the extrusion to make sure the new filament is flowing smoothly and evenly. You can do this by printing a small test object or using the manual extrusion option in your software to extrude a small amount of filament. Check the extrusion for any irregularities or inconsistencies.

By following these steps, you should be able to successfully load your new filament and continue your 3D printing project with ease.


If you encounter issues while changing your 3D printer filament, don’t panic. Here are some common problems and solutions to help you troubleshoot:

Filament Not Extruding

If you notice that your 3D printer is not extruding filament, there could be several reasons for this issue. First, check if the filament is loaded correctly and is not tangled or caught on anything. If it is, remove it and reload it properly.

Next, check if the nozzle is clogged. Sometimes dust or debris can get stuck in the nozzle, preventing the filament from extruding. To fix this, heat up the hot end and use a needle or a small wire to clear the nozzle.

Finally, check if the temperature is set correctly. If the temperature is too low, the filament may not melt properly, resulting in poor extrusion. Adjust the temperature accordingly and try again.

Filament Jammed

If your filament is jammed, don’t force it out. This can cause damage to your 3D printer. Instead, follow these steps:

  1. Turn off the 3D printer and let it cool down.
  2. Remove the filament from the extruder.
  3. Heat up the hot end to the temperature required for the filament you are using.
  4. Use a needle or a small wire to clear the nozzle.
  5. Reload the filament and try again.

Filament Snapped

If your filament has snapped during the printing process, don’t worry. Here’s what you can do:

  1. Pause the print job and let the hot end cool down.
  2. Remove the filament from the extruder.
  3. Cut off the snapped part of the filament.
  4. Reload the filament and resume the print job.

If you encounter any other issues while changing your filament, refer to your 3D printer’s manual or contact the manufacturer for assistance.
