Filament leakage is a common problem when using 3D printers for model printing. This phenomenon not only affects the beauty of the print, but also may reduce the print quality. The following are some effective ways to solve the problem of filaments leakage:
Enable and adjust pullback Settings:
The pulled-back setting is a key step in resolving filaments leakage. As the printhead moves from one position to another, the pull-back function pulls the consumables back some distance from the nozzle, preventing the molten plastic from dripping as it moves. In slicing software, such as Cura and Simplify3D, you can set the pull-back distance and pull-back speed. Typically, the pull-back distance is between 0.5 and 2.0 mm, while the pull-back speed should be between 60 and 100 mm per second, depending on the consumables and printer type used.
Adjust the printing temperature:
Too high a printing temperature can make the plastic too thin, which makes it easier to seep out. Appropriately reducing the temperature of the extruder can improve this problem. Generally, the printing temperature of PLA filament is between 180 ° C and 220 ° C, and ABS is between 200 ° C and 250 ° C. Try lowering the temperature by 5 ° C to 10 ° C to find the most suitable printing temperature.
Optimize printing speed:
Printing too fast can cause the plastic to not have enough time to cool and cure, resulting in leakage. Properly reducing the printing speed, especially in parts of the model with more detail or requiring high precision, can reduce filaments oozing out. At the same time, increasing the moving speed of the print head, especially in the air jump, can reduce the seepage time of molten plastic.
Use high quality consumables:
Low-quality consumables may contain impurities or moisture, which will affect the consistency of their melting and extrusion, resulting in filaments oozing out. The use of high-quality, reliable sources of consumables can fundamentally reduce this problem.
Regular printer maintenance:
Ensure that all parts of the printer are clean and operating properly, especially the nozzle and feeder parts. Clogged or worn parts can cause poor flow of consumables, which can lead to problems with filaments leaking out.
Through the above methods, you can effectively reduce or eliminate the problem of filaments leakage in the 3D printing process, improving the quality and efficiency of printing.
