Its function is pretty simple and works by retracting the filament back into the nozzle before the head moves. Some filaments are worse than others such as Nylon and HIPS. In your 3D printing journey, you're going to come across plenty of software that has its purpose. Our article on cleaning your nozzles provides more details on the possible ways to clean your nozzle. Thus, 3D printing professionals constantly have to adapt and understand problems so that they may come up with solutions. Your email address will not be published. If you feel you have the correct retraction settings, but you are still encountering these issues, try decreasing your extruder temperature by 5-10 degrees. If the Wipe function is active, you can also prevent unsightly dents at the change points of the individual layers.

Other filaments print at much higher temperatures, such as PETG (220 TO 245 °C) or Nylon (230 to 260 °C). If you’re in the field of 3D printing, you might have come across an issue of strings of melted plastic or plastic oozing from your 3D prints. Just as with the retreat distance, you should aim for a sweet spot in the retraction speed.
What Causes 3D Prints to Have Stringing & Oozing? If you lower the temperature while the print speed is too high there’s a chance that your material will start under extruding.
If the nozzle is moving at a high speed, with a high temperature, and no retraction settings, you can bet you’ll experience stringing and oozing at the end of your 3D print.
A recommended small nozzle is the e3d V6*, as it rarely causes stringing problems. The print speed plays just as much of a role as the print temperature. This setting is simple in Simplify3D, while the configuration in Cura is a little more complicated. While the extruder does not receive any command to convey the filament while it is traveling along this path, the portion of the filament that has already been melted tends to naturally drip off the nozzle, leaving behind very thin strands of plastic. This can have a significant impact on the final print quality. Higher settings minimize the stringing problem! 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. All 3D printing filaments are prone to moisture pickup when exposed to open air. It’s not ideal when your 3D prints are stringy so you want to get this sorted out quickly.eval(ez_write_tag([[300,250],'3dprinterly_com-box-4','ezslot_6',110,'0','0'])); Below are some of the simplest and easiest solutions that can be implemented without requiring any major tools or techniques.
The reason for this is that parts of the material were exposed to the heating element. Stringing is just one of the many issues you can encounter when you’ve decided to take on 3D printing as a hobby or as a profession. Setting a faster travel speed for the print head as it moves across gaps in the print reduces the time in which no printing is happening. The filament expands when your PLA is exposed to the high printing temperatures in the hot end. All filament materials have a prescribed range for the printing temperature to get the best results out of them. Intuitively, this means that reducing the printing temperature should help avoid the stringing problem. If you’re unsure if retraction is turned on, it’s always wise to check it. But there are ways you can help reduce or eliminate stringing all together.
Depending on how bad the stringing is, you might still be able to salvage your build with some heavy sanding and polishing.
As with many problems related to 3D printing, addressing an issue with stringing takes a multi-pronged approach. If the temperature is too high, the plastic inside the nozzle will become less viscous and will leak out of the nozzle much more easily.
There is no one-size-fits-all solution when it comes to stringing. The most reliable method to reduce stringing is to take advantage of your 3D printer’s retraction feature. Stringing happens when the plastic filament oozes out of the nozzle in places where there should be no printing taking place (thus, the other term for stringing – “oozing”). This is because a portion of the filament has already been exposed to the heating element and is essentially in a molten state inside the nozzle.

Is PLA more Susceptible to Stringing than other Filaments? However, make sure that the temperature setting is still within the print temperature range for PLA.
