means that your nozzle is not extruding as much plastic as the
software expects. For a full description of this issue and how to
correct it, please read the Not Extruding Enough Plastic section.
6:Stringing or Oozing
Stringing (otherwise known as oozing, whiskers, or “hairy”
prints) occurs when small strings of plastic are left behind on a 3D
printed model. This is typically due to plastic oozing out of the
nozzle while the extruder is moving to a new location. Thankfully,
there are several settings within Simplify3D that can help with this
issue. The most common setting that is used to combat excessive
stringing is something that is known as retraction. If retraction is
enabled, when the extruder is done printing one section of your
model, the filament will be pulled backwards into the nozzle to act
as a countermeasure against oozing. When it is time to begin
printing again, the filament will be pushed back into the nozzle so
that plastic once again begins extruding from the tip. To ensure
retraction is enabled, click “Edit Process Settings” and click on the
Extruder tab. Ensure that the retraction option is enabled for each
of your extruders. In the sections below, we will discuss the
