How to Clean Your 3D Printer’s Nozzle?

How to Clean Your 3D Printer's Nozzle

3D printers are one of the best new technologies in the world today. They’ve been used to print everything from prosthetic limbs for amputees, to full scale houses. However, 3D printing is not without its drawbacks and problems. One of these pitfalls is how difficult it can be to clean a nozzle that has become clogged with filament at some point during its use.

The following article will provide an overview on how you can take care of your 3d printer by cleaning out the nozzle so that it won’t clog again. It also provides tips on how you can prevent this problem from happening in the first place.

1. You’ll need a screwdriver and wire brush in order to do this (not included with the printer). Find them, go through the steps below, and you’ll be printing again in no time.

2. First, open up the 3D printer.

3. Once you’ve opened the printer, locate the nozzle assembly. It will have a piece of metal that is shaped like an arrow with two holes in it, one on either side. The filament passes through this hole and into the nozzle itself. You should see a small opening on top of the assembly as well, which will allow you to see how clogged the nozzle is.

4. Insert your wire brush into the upper hole and turn it until you can feel that it has reached the end of its travel. Then, remove the brush and use your screwdriver to unclog whatever filament may be in there. It might take a bit of work, but just remember how much time was spent printing that model you’re trying to unclog.

5. Now, go ahead and insert your wire brush into the lower hole and use it to free up any filament lodged in the nozzle itself.

6. Once this is complete, clean out any excess filament from the piece of metal that we mentioned earlier. You may need to use a small brush like the one that came with your printer for this.

7. Now, you’re finished! You can close up your 3d printer and get back to printing as usual.

How to Prevent Clogs In First Place?

Here are some tips for how to prevent this problem from happening in the first place:

1. The best way to do this is to clean out the 3d printer nozzles after every use. This will help ensure that you have a nice, smooth and easy path for the filament to pass through when printing your next project!

2. Also, try not to print models that have small areas with fine details too close to the end of the filament. This will help prevent filament from being very close to the end of your nozzle, which can then get caught on something and block it!

3. Be sure to check how much filament is left as well! When a printer has been printing for an extended period of time, and there’s not enough material left in the spool, sometimes this can cause the filament to poke out of the nozzle and block it.

4. Finally, how much extrusion you’re using can also make a difference. If you’ve gone too far into fine detail with your 3D print, turn down how much material is being extruded, as doing so can help ensure that there isn’t so much that extends past the nozzle.


We discussed some ways to clean your 3D printer nozzle. It’s important to keep a clear and unobstructed path for the melted material so that it can flow through the machine without any issues. The easiest way is with compressed air; alternatively, you could use a brush or pipe cleaner by inserting them into the opening of the nozzle while running water over them in order to flush out debris or clogs within.
