Different Ways To Solve The Problem Of Blockage Of 3D Printer's Nozzle
The nozzle is the most simple and crucial part of the parts of 3D printing machine, it is important to keep the daily maintaining for the nozzle. In order to ensure the successful ratio for the model, we will show you some easy methods to clear the nozzle.
1, Prevent the cleaning of 3D FDM printer
The best way to prevent the block of nozzle is to clear it regularly, especially for the people who usually replace different filament. Because some filaments have different characteristics, and there’s different reaction for the changing of temperature, especially rubber-like filament. While changing the filament, must change it while the nozzle is over-hot in order to avoid the material become cold. When you put in the new filament, do not push filament in it with force, this can also avoid the accumulation of inner material in the nozzle.
2, Clean Large 3D printer’s nozzle
Before cleaning the nozzle, first please make sure if it can work. Sometimes, due to push its gear, the filament will be broken at the enter of nozzle. Another question probably is the malfunction of heater, and it causes the unusual heating, etc. In order to avoid the malfunction and block, first you need to make sure that the tip of nozzle and the area around the heater are clean. The simplest way to confirm it is using the wire brush the nozzle and its surrounding area.
3, Using needle to solve the blockage
The most common problem with nozzle is blockage, it is also possible because the cooling filament become solidity in the nozzle then the filament can’t squeeze out while printing. At this moment, the first thing you need to do is heat the extruder and nozzle to avoid filament become soft and block the filament, then using needle pull it out.
Tips:
Or you can use a hot air gun to manually heat the printing head without turning the machine on, and then use a needle to push it out. As shown in below picture:
Also, if the printing head is still blocked, there is another thing you can do. In other words if you use ABS for large 3D printing. You can take the nozzle off from large FDM 3D printer, then put it in acetone and let stand for a few hours. The acetone will melt the filament which is in the nozzle and make it clear.
These are some simple and effective ways to solve the problem of blockage of nozzle. If you can’t solve this problem by the different methods. You can consult us, we will arrange professionals to help you
