In the 3D printing process, the plug problem of PLA wire often causes problems for makers and enthusiasts. The plug not only affects the printing efficiency, but also may lead to the decline of the printing quality. This article will introduce several methods to solve the problem of PLA wire plug in detail, to help users effectively deal with this common fault.

First of all, clogged nozzle is one of the most common problems. After each printing, the nozzle is not cleaned in time, and the residual material solidifies in the nozzle is the main cause of blockage. Methods to solve this problem include: first heating the nozzle to the normal temperature of PLA consumables melting, usually between 195 ° C -220 ° C. Then, try to manually insert the wire into the nozzle. The downward pressure of the manual feed will cause the consumable wire to penetrate and bring out the blocked residue. If the nozzle still does not produce the wire normally, you can use a 1.5mm six-edge wrench to dredge the throat or nozzle. In daily maintenance, the nozzle must be emptied as soon as possible after printing to avoid solidification and blockage of residual materials.

Secondly, the loss of the consumable line is also one of the common reasons for the plug. In the feeding process, if the consumable line is damaged, it is easy to get stuck in the pipe, affecting the normal feeding. The solution includes: return the material and cut off the damaged part of the consumable line, and then re-feed, pay attention to maintain the smoothness of the consumable line. The use of high quality PLA wire can reduce the plug problems caused by impurities and expansion.

In addition, the nozzle heating temperature is not up to standard is also an important reason for not producing silk. Check whether the heating temperature setting of the nozzle matches the melting temperature of the consumables. If the temperature setting is correct but the nozzle is not heated normally, check whether the heating rod and heating resistor are in poor contact. The ABS printing nozzle temperature is between 210 ° C and 230 ° C, and the PLA printing nozzle temperature is between 195 ° C and 220 ° C, ensuring that the correct temperature setting can effectively prevent plugs.

The cold pull technique is another effective solution. The trick is to wait for the temperature to drop slightly below the freezing level and quickly pull the wire out, at which point most of the wire should be solid. In this process, the solid wire will carry out scattered residue in the hot end. Cut off the contaminated part and repeat the process until the pulled out wire is clean. Then, insert the real wire into the extruder, replace the piece of wire used for cleaning, and try to extrude some plastic, which should work normally.

If the preceding methods fail to solve the problem, turn off the power immediately and contact after-sales engineers. In daily use, regular maintenance and cleaning of 3D printers, the use of high-quality PLA filament, and following the correct temperature Settings can effectively reduce the occurrence of plug problems.

Through the above methods, makers and enthusiasts can effectively solve the plug problem of PLA wire, improve the efficiency of 3D printing and the quality of the work.
