7.2. Printing after Replacing Filament
This section describes the process of changing the filament before a new print job. It is the process of
unloading a filament and loading a new filament, as described in
“
6.6. Replacing Filament
” and then
beginning the print.
The process can be divided into the following steps:
1) Unload the old filament (A) (Remove the filament (A) from the extruder)
{Prepare>Unload Filament} ..
Nozzle heating temperature (UT)
..“Pull Out Filament” ..{Unloading Stop}
2) Remove the old filament (A) from the filament carrier and mount the new filament (B)
3) Load new filament (B) (Insert the new filament (B) into the extruder, melt it and push it out of the
extruder nozzle)
{Prepare>Load Filament} ..
Nozzle heating temperature (LT)
..“Insert Filament” .. {Loading Stop}
4) Select the G-Code file created with the temperature condition of the new filament, and print.
Even experienced users often make mistakes when setting the nozzle heating temperature, i.e. the
extruder nozzle temperature, during loading and unloading.
During unloading, set the nozzle heating temperature (UT) to pull out the existing filament (A).
During loading, set the temperature to insert the new filament (B) into the extruder and discharge
as
it,
well as the nozzle heating temperature (LT) to remove the filament (A) that is already melted in the
nozzle. It is important to load a sufficient amount of new filament (B) and discharge it in order to
remove old filament (A) remaining in the nozzle.
This is the most important step in replacing a filament with a new filament
.
PLA is generally melted at a lower temperature than ABS. When replacing an ABS filament with a PLA
filament, if the nozzle heating temperature during loading (LT) is set to the PLA temperature, the ABS
filament inside the nozzle will not melt, and thus will remain as residue, plugging the nozzle.
When replacing a PLA filament with an ABS filament, the PLA filament remaining on the nozzle’s inner
wall is sticky and cannot be easily removed. For this reason, a sufficient amount must be loaded to
remove the PLA from the nozzle several times to avoid nozzle plugging.
The following table shows the nozzle heating temperatures (UT)/(LT) according to the filament type
(A)/(B) when the filament (A) is replaced by the filament (B) given an ABS temperature (extruder
temperature) of 240
o
C and a PLA temperature of 210

The values in the table are just examples, and are not absolute values. The users must set the
optimum condition based on their experience.
