When you lot use a 3D printer, filament melts and comes out of the nozzle, but it can get stuck and clog your machine. If you lot notice your filament isn't going through the nozzle or it comes out stringy, information technology might exist time to clean. You can either force the clog out while the nozzle is fastened to your car or take it off completely to practice a deep make clean. When you lot're finished, your printer should run smoothly!

1
Unload the filament currently in your printer. Look for the "Unload" option on your 3D printer's carte du jour or the plan you employ to run it. Once you select it, wait until the nozzle heats upwards earlier pulling out the filament. Slowly pull out the filament and then you don't impairment your machine.^[one]
- If your filament doesn't come up out, estrus upward the nozzle more until y'all can pull it easily.

Go into your printer settings and start heating the nozzle to about 200 °C (392 °F). This will help loosen whatsoever leftover filament that could be clogging the nozzle. Let the nozzle heat completely before moving on.^[2]

Tip: 3D printers let you to adjust the heat settings in multiple parts of the machine. Make sure y'all're only heating the nozzle while you lot clean it.

Push a articulate ABS or nylon filament into the nozzle and agree information technology for ten-fifteen seconds. ABS plastic and nylon take high melting points then it's easier to command to pick up clogs. Feed the end of the filament into the pigsty on superlative of your nozzle. Push button the filament equally far as you can through the nozzle until information technology stops. Go on the filament there for about 10-xv seconds and so it has a chance to melt slightly.^[iii]
- Avert using whatsoever materials that have a lower melting point since they won't retain their shape every bit well.
iv

Pull out the filament and check for dirt before cutting the end off. After 10-15 seconds, quickly pull the filament back out of the nozzle. Since the ABS or nylon is clear and melted slightly, you should easily meet any residue that was pulled out of your nozzle. Cut about 5 cm (2.0 in) from the muddy end of the filament with a pair of pair of scissors or snips.^[4]
5
Repeat the process until the filament comes out clean. Keep putting the terminate of the filament into your nozzle and pulling it out afterward 15 seconds. As yous keep working, the filament should pull up less dirt and crud. Keep cleaning the nozzle until the filament is clear when you pull it out.^[5]

- Wire brushes can be purchased from your local hardware shop.
- Bank check the nozzle's packaging to see if it's safe to use a metal brush on it.
two
Heat the nozzle to 150 °C (302 °F). Heating the nozzle helps loosen the threads and make information technology easier to remove. Set the temperature to at least 150 °C (302 °F) so the metallic can aggrandize.^[7]
- Removing a nozzle cold could impairment the threads and make it more difficult to screw back on.
three
Remove the nozzle with a wrench. Once the nozzle is heated, secure a wrench to the nozzle and rotate it counterclockwise to remove information technology. Fix the nozzle on a surface that won't go damaged past the heat.^[8]
- Don't touch on the nozzle with your bare hands or else you volition get burned.
iv
Submerge the nozzle in acetone for 15 minutes earlier drying it. Fill a container with plenty acetone so your nozzle is completely submerged. Leave the nozzle alone for fifteen minutes and so the acetone has fourth dimension to break down. Then, take the nozzle out of the acetone and dry it with a lint-free cloth or paper towel.^[nine]
- Acetone is commonly used every bit boom polish remover and can exist purchased at your local drugstore.
- The acetone helps loosen the clay and crud on the exterior of your nozzle as well as breaks apart the filament inside.
v
Heat the nozzle with a oestrus gun for i minute. Set a heat gun then information technology'due south pointing direct up and plough information technology on. Catch the nozzle with a pair of pliers and concord it straight to a higher place the heating unit. Let the nozzle heat up completely, rotating it effectually so it'due south evenly distributed. At this time, any filament residuum should loosen up more. After 1 infinitesimal, turn the oestrus gun off and set up it aside.^[10]
- Heat guns can be bought from hardware stores.
- Don't bespeak the heat gun straight at anyone since it could cause burns over time.
six
Push any clog through the nozzle with a thin wire or needle. Proceed a house grip on the nozzle with your pliers while you poke a wire or needle into the nozzle. Scrape the sides on the inside of the nozzle to remove any residual. Proceed cleaning the nozzle until the clog is removed and yous can see through it.^[11]
- Wipe the wire or needles clean whenever there's residue stuck on them.
Tip: If the nozzle still isn't clean afterward 2-iii minutes, estrus it again so the filament doesn't solidify again.
