How To Clean 3D Printer Nozzle Effectively?

When you use the best 3D printer, the filament melts and releases the nozzle, but it might get stuck and clog the equipment. If you realize the filament is not going via the nozzle or it releases stringy, it can be time to sanitize. You could both force the clog out, whereas the nozzle is attached to the machine, or take it off entirely to do an intensive clean. When you are completed, your printer might work better and effectively.

Technique 1: Pulling clogs from the nozzle

1. Unload the filament at now in the printer

Search for the “Unload” option with the 3D printer’s menu or the program you need to run it. When you choose it, keep waiting till the nozzle heats up before pulling out the filament. Next, you can slowly pull out the filament so that you might not damage the machine. 

If your filament can not come out, heat the nozzle much more till you could pull it simply. 

2. Preheat the nozzle up to 200 degrees Celsius

After the filament is unloaded, the nozzle might begin to cool down on itself. Move inside the printer settings and begin heating the nozzle until 200 degrees. That might assist in loosening the leftover filament which can be clogging the nozzle. Make the nozzle heat entirely before moving on. 

Hint: 3D printers permit you to customize the heat settings in various components of the equipment. Ensure you are specifically heating the nozzle while you can sanitize it.

3. Push the clear ABS or filament inside the nozzle 

ABS plastic and nylon get high melting points so that it is handy to manage to choose clogs. Feed the filament’s end inside the hole above the nozzle. Next, you might push the filament as far as you could through the nozzle till it can stop. 

Keep the filament here within 15 seconds so that it comes with a chance to melt mildly. Besides, you might avoid using materials that get a low melting point as they will not retain the shape at all. 

4. Pull out the filament and test the dirt before cutting the end off

After 15 seconds, rapidly pull the filament back out of the nozzle. As the ABS or nylon is melted mildly, you can simply realize any residue which was pulled out of the nozzle. Then, you can cut around 5cm from the dirty filament’s end with a pair of snips. 

5. Repeat the process till the filament comes out clean

Keep going to put the filament’s end inside the nozzle, and pull it out after 18 seconds. As you keep operating, the filament might pull up less dirt and grime. Next, keep sanitizing the nozzle till the filament is clear while you can pull it out. 

You have to cut the dirty end off of the filament so that you might not return it to your nozzle. 

Technique 2: Making a deep clean with Acetone

1. Scrub the stuck-on material above the outside with the wire brush

You can leave the nozzle above the printer so that it is held conveniently. Operate in back-and-forth movements and implement firm pressure with the brush to scrape the filament residue off. Alter the angle and brush’s direction as you operate. 

The wire brushes might be bought from the local hardware shop. You might test the nozzle’s packaging to test if it is convenient to use the metal brush on it. 

2. Heat the nozzle until 150 degrees Celsius

Heating the nozzle supports to loosen the threads and make them simple to remove. You can set the temperature minimum of 150 degrees so that the metal might enlarge. Taking out the nozzle cold might ruin the threads and make it quite tough to screw back on. 

3. Take out of the nozzle with a wrench

When the nozzle is heated, you can guarantee the wrench to the nozzle and rotate it counterclockwise to take it out. Next, you might set the nozzle on the surface which might not get damaged by the heat. You could not touch the nozzle with the bard's hands or else you might get burned. 

4. Submerge the nozzle in the Acetone within 15 minutes before drying it

You can fill the container with sufficient Acetone so that the nozzle is entirely submerged. Then, you might leave the nozzle alone within 15 minutes so that the acetone takes time to break down. Moreover, you get the nozzle out of the acetone and dry it with a lint-free cloth or paper towel.

Acetone is popularly utilized as a nail polish remover and might be bought at your local shop. The acetone assists in loosening the dirt on the nozzle’s outside and breaking apart the filament. 

5. Heat the nozzle with the heat gun within 1 minute

You might set the heat gun so that it is pointing straight up and switch it on. Take the nozzle with pliers and hold it quickly onto the heating unit. Make the nozzle heat up entirely, and rotate it nearby so that it is evenly spread. At this moment, the filament residue might loosen up a lot. After one minute, you can switch the heat gun off and set it aside. 

The heat guns might be purchased from the hardware shops. You can not point the heat gun directly at anybody because it might lead to burns over time. 

6. Push the clog via the nozzle with a slimy wire or needle

Keep a firm grip above the nozzle with the pliers while you can poke the wire or needle inside the nozzle. Next, you have to scrape the sides above the internal nozzle to take out the residue. Keep going cleaning the nozzle till the clog is eliminated and you might realize it through it. 

Finally, wipe the needles or wire clean whenever there is residue stuck on them. 

Final thoughts

That’s all about the tips related to cleaning the 3D printer nozzle. Finally, we hope you can accumulate some knowledge involved in cleaning the nozzle rapidly and effectively in the near future.
