While adjusting the retraction distance, increase or decrease it in small increments to get the best suitable length because it varies depending on the type of filament you are using. The default retraction distance on Cura is 5mm.įor Direct Drive extruders, retraction distance is on the lower end, of around 1mm to 3mm. The distance will tell the nozzle to pull back the amount of filament according to the specified length.Īccording to the experts, the retraction distance should be between the 2mm to 7mm distance for Bowden extruders and should not be more than the length of the printing nozzle. The retraction distance should be adjusted accurately because both too low and too high retraction distance can cause printing problems. Retraction distance or retraction length specifies the length of the filament that will be extruded from the nozzle. Now that you have a basic understanding of retraction in 3D printing, let’s explain the basic retraction terms, retraction length and retraction distance. We can be specific on telling our 3D printer how exactly to retract, whether that be the length of retraction, or the speed at which the filament is retracted.Īccurate retraction length and distance can reduce the chances of different problems mainly the stringing and oozing. It is a setting which you’ll find in your slicer software, but it isn’t always enabled.Īfter you have understood the basics of printing speed, temperature settings, layer heights and widths, then you start to get into the more nuance settings like retraction. When you hear that rotating noise backwards and see filament actually getting pulled back, that is retraction occurring.
