The 3D printer nozzle usually accumulates a large amount of plastic that, if not cleaned, burns and turns black over time.<\/p>\n\n\n\n

This implies a danger in the quality of the pieces, since if burnt plastic comes off the nozzle can leave black dots around the printed models.<\/p>\n\n\n\n

One of the symptoms that the nozzle needs cleaning is that when extruding the filament does not flow down consistently, but bends<\/strong> to one side. <\/p>\n\n\n\n

The correct thing is always that the filament extrudes smoothly downwards (without deviating to the side).<\/p>\n\n\n\n

Today I want to do a list of the different ways to clean the 3D printer nozzle<\/strong> (inside and out), since keeping the extruder nozzle clean can save you money<\/strong> and also deliver high quality 3D printed parts.<\/p>\n\n\n\n

To clean the nozzle the Hotend must be hot<\/strong>.<\/p>\n\n\n\n

1. Keep the mouthpiece clean<\/h2>\n\n\n\n

One of the best ways in the world to clean is to find the origin of the dirt and eliminate that cause from the root.<\/p>\n\n\n\n

In case of 3D printer nozzles, the reason they get dirty is because you never clean them and you let the plastic build up<\/strong>.<\/p>\n\n\n\n

You must clean the nozzle before and after using the 3D printer, always<\/strong>.<\/p>\n\n\n\n

Use a rag or paper napkin to clean the nozzle (being very careful not to burn yourself), since you must do it while hot when the plastic is loose.<\/p>\n\n\n\n

Get into the routine of always cleaning, before and after each print<\/strong> and you will see how the nozzle of your printer will not only always be clean, but it will last much longer, saving you money.<\/p>\n\n\n

2. Use tweezers to remove the burned plastic<\/h2>\n\n\n\n

When the molten filament has stuck to the nozzle and cannot be removed with a rag, then use tweezers or pliers to remove it.<\/p>\n\n\n\n

In this case, you can play with the temperature so that it softens and it is easier to peel it off.<\/p>\n\n\n\n

Try putting it between 150\u00b0C and 215\u00b0C and then carefully remove any plastic stuck to the mouthpiece.<\/p>\n\n\n

3. Cold pull<\/h2>\n\n\n\n

One of the options for clean the nozzle inside<\/strong> is to use the cold pull, this method consists of lowering the temperature of the nozzle to 90 \u00b0 C and then pulling the filament until it is completely removed.<\/p>\n\n\n\n

To use this method you need that the nozzle is hot<\/strong> (at the temperature at which the filament melts) and with the filament inside the nozzle<\/strong>, including extruding a bit manually.<\/p>\n\n\n\n

Then you have to lower the temperature to 90 \u00b0 C and then simply pull the filament until it comes out or "unstuck" from the nozzle, coming out completely.<\/p>\n\n\n\n

You may encounter a little resistance when pulling, but the filament will come off making a little noise as you do so.<\/p>\n\n\n\n

Some recommend doing it with PETG filament that melts at a higher temperature and sticks to the PLA, pulling everything together.<\/p>\n\n\n\n
