How to Clean a 3D Printer Nozzle? Easiest Methods

The 3D printers are not only fun to work with but the precise, accurate, and crisp results of a good quality printer can astonish you. Learning more and more about 3D printers gets us excited to try 3D printing each time but the 3D printer is not only a name for fun or excitement as it is a mechanical object, it requires some attention and maintenance too. Over time, you might have noted that your 3D printer is not giving results as it used to. The reason for this problem is nozzle gets fully or partially blocked or clogged.

What can be done in such a situation? Should you replace the nozzle? Or do you need to buy a new 3D printer? Relax, there is no need to panic as we came forward to save the day by helping you with this problem. To solve this matter, we brought a complete article with a step-by-step guide that will prove to be a lifesaver for your 3D printer. In this article, we are going to have a look at how to clean a 3D printer nozzle for better and enhanced working.

How to clean a 3D printer nozzle?

Excessive or continuous usage of a 3D printer makes the nozzle dirty that results in clogging or blockage so it is very crucial to clean the 3D printer’s nozzle on time. If you do not keep up with the cleanliness of the nozzle, you might lose your precious or expensive 3D printer. Let’s get into the deep waters to find everything related to the cleanliness of the nozzle and enhancing the printer’s performance.

Procedure: Cleaning a 3D printing nozzle

Before we start our guide of cleaning the nozzle of a 3D printer, it is important to discuss some crucial factors such as safety measures, protocols, or precautions so you do not get hurt while cleaning the nozzle and can have a safe experience. The safety measures you need to consider are:

  • Make sure the power cord of the 3D printer is unplugged from the socket.
  • If you recently used the printer then the nozzle can be hot, do not touch it and let it cool down.
  • Be careful while using pointed or sharp things like a cleaning pin.
  • Use heat-protective gloves where needed.

Let’s begin with the main part of today’s guide.

Step 1: Identifying the issue

The first and foremost step of the procedure is to identify where the problem is. If your 3D printer is not working properly then some chances are that there can be other problems too. Before opening or disassembling the nozzle, you should check other parts so you do not have to disassemble the nozzle in vain. The other problems can be:

  • Faulty extruder
  • Z offsetting
  • Unlevel bed
  • Hot end jam
  • Inconsistent filament supply

Step 2: Dusting the exterior

The second step you have to follow after the determination of the clogged nozzle is to dust the exterior of a nozzle to clean the dirt and debris. It is crucial to remove outside debris so it does not get inside while cleaning to create more problems. You can use a wire brush to dust the outside of the nozzle. A brass wire brush will prove to be a great option as it will clean efficiently and will not scratch the nozzle.

Step 3: Cleaning the nozzle with a pin

The next and most crucial step of the procedure is to clean the nozzle with a pin. In this step, you have to heat the nozzle to make it soft but do not heat it to the melting temperatures. You can use a heat gun to set the temperature accordingly. Make sure you are wearing heat-protective gloves to be safe from the heated nozzle. Now, take a pin or a needle and remove the excessive filament in the nozzle by pushing it out.

Step 4: Checking the results

The fourth step in the cleaning procedure is to check the nozzle for performance. You have to print a 3D model or just print a small 3D layer to check if the nozzle works properly as the new nozzle would. If it works properly, you can end the procedure right now but if you are still facing some issues, we recommend you move to the next step.

Step 5: Re-cleaning

You are almost done and here is the last step in case you are still having troubles after step number 4. The reason that nozzle still does not work properly is that there is still some clogging in the nozzle and you are required to re-clean it by following the procedure again from step number 3 until it starts to work fine.

Conclusion

As you are at the conclusion part of the article on how to clean a 3D printer nozzle, we can assume that you must have gone through everything in detail for easy and convenient understanding. At first, you might think of the procedure as a complicated or complex one but we are sure after reading this guide your thoughts are changed and there is no problem for you in understanding and following the guide to make sure your nozzle is clean and provide you, high-quality 3D models. All that is left for you is to follow the steps listed above.

To help you more in this concern, we summarized all the steps of the cleaning procedure so you can revise them and check again in case you missed something essential. First, we identified the problem by looking at different parts then we dusted the exterior of the nozzle. Lastly, we cleaned the nozzle with a pin, checked the results, recleaned it if it still does not provide proper results. You are all set to go.
