Extruder(Management)

The nozzle of the Extruder is located at the very bottom of the Extruder, and it is a part that creates a
sculpture as the filament gets melted and pushed out.
The nozzle is a consumable part in the printer, and it needs to be replaced after it is used for a long time
due to the normal wear or due to the accumulation of carbonized residues of the filament and foreign
substances inside of the nozzle. However, if it is not appropriately managed, the printing quality becomes
poor as the problem occurs a lot earlier than the estimated lifecycle, and in severe case, the nozzle needs
to be replaced as the hole of the nozzle gets clogged. In order to use the nozzle with stable printing
quality for a long time, clean the nozzle regularly.

1. How to Maintain the Nozzle in a Good Condition

Once the clogging of the nozzle occurs, there is a high probability that the problem constantly occurs until
it is replaced. Since the nozzle can be maintained cleanly according to user's care, keep in mind the
following items.
① Check and manage the condition of the nozzle regularly
② If the thickness of the filament that is discharged from the nozzle is too thin or the discharged
amount is not consistent during the printing, stop printing and proceed with the nozzle cleaning.
Since it is unknown when the foreign substances inside of the nozzle would deteriorate the
condition of the nozzle, the counter measure must be taken immediately when the symptom
appears.
③ When replacing a filament, clean the nozzle sufficiently as much as possible. Especially​ when
the filament is changed to a filament with different printing temperature condition, the
nozzle must be cleaned as mandatory.
④ In general, the filament causes more and more pollution on the nozzle as it has colors
(including white) and as it gets darker. If such filament is mainly used, frequently clean the nozzle.
⑤​ If a filament gets hardened after getting melt once, it gets different characteristic from the initial
state. In other word, if the filament inside of the nozzle continues to repeat being heated/cooled
without being discharged, it turns into a pollutant that can't be discharged normally. Therefore, do
not let the filament in the nozzle repeat being heated/cooled without being used.
⑥​ Once the vacuumed packaging of a filament gets opened, the filament starts to be polluted by
the humidity and dusts. If such pollutants get accumulated a lot, it causes the clogging of the
nozzle. Therefore, use it as fast as possible once it is opened, and it is very helpful to use a dust
filter in order to filter the dust on the surface of the filament.

2. Cleaning the Inside of the Nozzle using the Loading

①​ Take out the filament sufficiently by using ​ { Control → Filament → Loading}​ of the function
menu. If a user doesn't stop it, the loading automatically stops after a certain amount of the
filament gets discharged.
Set the temperature of the Load Filament to the temperature of the filament to be used.
② If the printing condition is not satisfactory even with the method in ​ ① ​ , repeat the process of ​ ①
once again after setting the temperature of the Load Filament higher than the temperature of the
filament that is used.
