The Brim option creates a single layer of
filament contacting and surrounding your
model, while the Raft option creates a layer of
material beneath the model. Click the ... button
to adjust Skirt settings (when None is
selected), as well as expert settings for the
Expert
Brim and Raft options. Refer to the
Settings
section for option details.
Diameter (mm) - This is one of the most important settings to get right. This should be set
to the average filament diameter specified by the filament manufacturer.
Flow (%) - This determines the amount of filament extruded in relation to the speed. This is
used to adjust for filament density variations. We recommend leaving this at 100%, as
changing it can lead to surface quality issues.
