Storage of filaments such as PVA/PA/PACF

As PVA is water-soluble and highly water-absorbent, and filaments will soften
after absorbing water, it will easily cause printing failure. During printing, it is
necessary to place desiccant in the filament bin, and it is recommended to keep
the humidity of the filament bin within 15%; Humidity status can be viewed on
the screen.
PVA will soften when the temperature is higher than 50℃, so it is not
recommended to dehumidify it during the chamber-heating state when printing
PVA.
PA/PVA/PACF all need to be stored in a sealed and dry environment. After
finishing printing, it is recommended to store the filaments in a drying box.
Filaments are easy to cause stringing and oozing when being exposed to
moisture, which will cause poor printing quality of models.

Thickening the height of the first layer and increasing the filament extrusion
amount of the first layer are beneficial to the adhesion of the first layer.
When printing small models with PLA (or the printing environment temperature
is lower than 25℃), it is recommended to set the raft temperature to 40℃.
When printing large models with PLA (or the printing environment temperature
is lower than 10℃), it is recommended to set the raft temperature to 50℃.
Make sure to close the equipment door and front door when printing models with
ABS.
When printing partial and small models, different printing speeds can be set in
the slicing software according to the layer height.
If you need to strengthen the partial part of the model, different filling amounts
can be set according to the layer height.
If the model is required to feature strong performance, it is recommended to
select 100% filling.
If the support is easy to break, it is recommended that the thickness of the
support should be more than 90%.
If the support is difficult to remove, it is recommended to increase the Z-axis
clearance of the support.
If you need to improve printing efficiency, you can increase the layer thickness.
5.5 Filament Parameter Setting
In order to obtain high-quality printing effect, different printing filaments require
different parameter settings, and Flashforge will configure the corresponding
printing parameters in the slicing software. If filaments of other brands are used,
the characteristics of the filaments corresponding to different filament brands will
be different, which may involve fine adjustment of parameters. You can use the
expert mode to adjust different parameters when slicing. The following are some
adjustment suggestions for reference only:
