Nozzles are the simplest and most critical part of 3D printer components, and it is very important to maintain them on a daily basis in order to ensure the success rate of model printing. Here, we show you some simple ways to clean your mouth.
I. cleaning and prevention of 3D printers
Cleaning the nozzle regularly is the best way to prevent nozzle clogging, especially for people who often change different consumables for printing. Because some consumables have different characteristics and react differently to temperature changes, especially those that imitate rubber. When replacing consumables, please be sure to replace the printing head when it is overheated to prevent material cooling. When loading new consumables, do not push consumables into the printing head with force, which can also prevent the accumulation of materials inside the printing head.
Ii. Cleaning the nozzle of 3D printer
Before cleaning the nozzle, first make sure that the nozzle can work normally. Sometimes, the material may break at the entrance to the print head because of the gears that push it. Another problem may be that there is a fault in the heating block, causing abnormal heating, etc. In order to prevent nozzle failure and blockage, first of all, it is necessary to ensure that the tip of the nozzle and the surrounding area of the heating block are clean. The simplest way to ensure this is to brush the nozzle and the surrounding area with steel wire, for example.
Use linear motion and make sure you approach from multiple directions. Using a wire brush, which provides greater friction, the charred material can be easily removed from the metal nozzle and the surface of the heating block. It is important to note that the strength of the brush should be maintained as some parts may be damaged by the wire brush.
Three, with the needle to solve the problem of blockage
The most common problem of nozzle blockage may also be that the cooling consumables solidify inside the nozzle, so that the consumables cannot be extruded during printing. At this point, the first thing you need to do is heat the extruder and nozzle to soften the clogging material and then push it out with a needle. To give you a little advice, or if you do not turn on the machine, try to use a hot air gunner to move the heating nozzle, and then push it out with a needle, which is also a good method, as shown in the figure.
Of course, there is one other thing you can do if the nozzle is still blocked after trying the steps above. That is, suppose you use ABS for 3D printing. Remove the nozzle from the head of the 3D printer and leave it in acetone for a few hours. Acetone melts the material in the nozzle and allows it to be removed with a needle.
