In fact, in many cases, the software may be able to find a travel path that avoids crossing an open space all together! This means that there is no possibility to create a string, because the nozzle will always be on top of the solid plastic and will never travel outside the part. The software is smart enough that it can automatically adjust the travel path to make sure that nozzle has a very short distance to travel over an open space. Thankfully, Simplif圓D includes an extremely useful feature that can help minimize the length of these movements.
However, long movements are much more likely to create strings. Short moves may be quick enough that the plastic does not have time to ooze out of the nozzle. The length of this movement can have a large impact on how much oozing takes place. 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.Īs we discussed above, stringing occurs when the extruder is moving between two different locations, and during that move, plastic starts to ooze out of the nozzle. Ensure that the retraction option is enabled for each of your extruders. To ensure retraction is enabled, click “Edit Process Settings” and click on the Extruder tab. 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. 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. The most common setting that is used to combat excessive stringing is something that is known as retraction.
Thankfully, there are several settings within Simplif圓D that can help with this issue.
This is typically due to plastic oozing out of the nozzle while the extruder is moving to a new location.
Stringing (otherwise known as oozing, whiskers, or “hairy” prints) occurs when small strings of plastic are left behind on a 3D printed model.
