ToAuto Studio: How to Prevent 3D Print Stringing

During 3D printing, the nozzle needs to move continuously. When the nozzle moves to next point through the open space, it might ooze melted plastic and then solidify and stick to printed parts. That's 3D printer stringing. 

1. Retraction
Solution: Set the retraction distance

Note: The most important setting for retraction is the retraction distance, which determines how much filament will be pulled back from the nozzle. Generally speaking, the more filaments are pulled back from the nozzle, the less likely it is to sag when the nozzle moves. The normal retraction length is set in the range of 6-10mm. Of course, it depends on the characteristics of the filaments.
2. Retraction speed
Solution: Set the Retraction speed

Note: Another setting related to the retraction is the retraction speed, which determines the speed of the filament retract from the nozzle. If the retraction is too slow, the filament will hang out from the nozzle and start to leak before moving to a new position. If the retraction is too fast, the filament may be disconnected from the filament in the nozzle, and even the rapid rotation of the driving gear may shave off the surface of the filament . There is a range, the retraction effect is better, between 3600-6000mm/min (60-100mm/s). The most ideal value depends on the actual material you use, so you need to do experiments to determine whether the different speeds reduce the amount of retraction.
