I think partial FMD 3D printing lovers have had met the same trouble when they are applying to use the machines, getting the nozzle clogged of your printer is quite an annoying yet normal phenomenon. So today, I would love to share my experience on how to avoid trouble based on the theory and my practice of it.
In this article, I will explain to you why and how the nozzle gets clogged while extruding in a stumbled way.
First, the quality of the filament should be the first to bear the brunt. There exist various brands of filaments in this marketplace, some are of rather bad quality while others possess a perfect one. Printing with filaments of bad quality sometimes will cause a bad consequence, like coagulation in the place of the nozzle or carbonization of the nozzle. On the other hand, if filaments are stored in any environment of unsealed package, oxidation, or dampness, they can be easily clogged inside the nozzle. I have been using some unused filaments for my printing works for a short period. With those filaments, getting my machine’s nozzle clogged is quite a common issue I faced in my every printing work. That’s rather annoying, isn’t it? As a result, I have changed new filaments which are preserved perfectly (tightly sealed under a perfect environment), and currently, I get my printing work much smoother.
Second, the printing environment and dampness of the printing process. If the environmental temperature can impact the biological clock of creatures, it also influences the machines. The printing process should be strictly controlled under a range of temperatures, any higher, colder, damper temperature or environment will directly affect the working performance of the extruder, causing the phenomenon of clogging and jamming. And in its ensuing course, it will directly influence the finished product.
Third, various filaments require different temperatures, in this case, setting the printing temperature in fitting the filaments is crucial to every single 3D printing process. Normally speaking, the optimal temperature of the PLA filament from our Geeetech brand should be in the range of 190-200℃, and, of course, some deviations are allowed for certain filaments in different environments, this can be easily adjusted in using our filaments. Lower temperatures in the printing process will cause a full dissolution of the filaments, and higher temperatures will bring out the carbonization of its filaments inside.
Fourth, an extruder with multiple nozzles is not allowed to apply filaments of different brands at the same time. For instance, to use of different types of filaments that come from the same brand or the same type of filaments that come from different brands should be strictly banned avoiding the clogging or jamming problem. Filaments of different qualities differ from each other to a large extent, and in a nutshell, they can’t be blended smoothly and perfectly.
How To Prevent Clogging of Your 3D Printer. Fifth, no extruding operation while the heating process has been triggered for a long while.
Sixth, the capability of heat radiation is insufficient. For instance, if the cooling fan in the printer fails to cool down the machine itself, or the environment is muggy, the higher temperature will indirectly cause the heating-up temperature of the machine.
