How to Change Ender 3 (Pro/V2) Nozzle

The Ender 3 (Pro/V2) 3D printer is one of the most popular printers in the market today. However, one of the downsides of this printer is that it requires occasional maintenance, including changing the nozzle. Changing the nozzle might seem like a daunting task, especially for beginners. In this blog post, we will guide you through the step-by-step process of how to change your Ender 3 (Pro/V2) nozzle.

By the end of this post, you will be able to switch out your nozzle with ease, giving you more control over your printing experience.

Step 1: Preparing Your Printer

Before starting the nozzle changing process, you must ensure that your printer is turned off and unplugged from its power source. Next, remove the filament from the printer by manually extruding it. After that, heat the printer’s hot end to a temperature of around 250 degrees Celsius to melt any filament that might have been left in the nozzle.

Step 2: Removing the Old Nozzle

With the hot end at temperature, use a socket or a nozzle wrench to unscrew the old nozzle from the hot end. Be careful with the nozzle as it may still be hot- use a cloth or protective equipment to handle it. It’s vital to ensure that the nozzle is completely screwed out before you move to the next step.

Step 3: Installing the New Nozzle

Now that the old nozzle is removed, it’s time to install the new one. First, ensure that the hot end is still at a temperature of around 250 degrees Celsius. Take your new nozzle and apply some thermal paste or heat-resistant tape to the threads. After that, screw the new nozzle back into the hot end using the nozzle wrench or socket and tighten it accordingly.

Step 4: Finishing the Installation

Once the new nozzle is tightly screwed into the hot end, it’s time to cool the printer down. Wait for the printer to cool down and then reinsert the filament into the printer’s extruder’s gear system. Manually extrude the filament to ensure that it is flowing smoothly through the nozzle and then do a test print to ensure that everything is working correctly.

Step 5: Clean Up Process

During the installation, there might be some filament that leaked out of the nozzle area. Be sure to clean this excess filament with a cloth or some solvent. Clean the surrounding areas around the nozzle and also take this time to clean out your hot end by using a hot end cleaning kit or some cleaning filament.


Changing the Ender 3 (Pro/V2) nozzle might seem like a difficult task, but it’s not impossible. With this guide, you now have the knowledge to change your nozzle safely and effectively, giving you more control over your 3D printing experience.

Always remember to take precautions when working with hot parts and take your time with the installation.
