sure that plastic can be properly attached to the surface before starting the next layer. If you
print the first layer too fast, the plastic may not have time to stick to the build platform. To
solve this problem, it is typically very useful to print the first layer at a slower speed.
EasyPrint 3D provides a setting for this exact feature. Go to the speed tab; you will see a
setting labeled ―First Layer Speed‖. For example, if you set a first layer speed of 50%, it
means that your first layer will print 50% slower than the rest of your part. If you feel that
your printer is moving too fast on the first layer, try reducing this setting.
6.1.3 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 EasyPrint 3D that can help with this issue. The most common setting used to
combat excessive stringing is known as retraction.
If retraction is enabled, when the extruder finishes 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
―Settings‖, choose [custom] mode and click on Retraction tab. In the sections below, we will
discuss the important retraction settings as well as several other settings that can be used to
combat stringing, such as the extruder temperature settings.
