![]() ![]() Start the printing process by changing the retraction speed and retraction distance step by step and see where the printer is performing well. Print a small object just for retraction tests that can be printed in a short period. It is the best technique to get the best suitable retraction settings. Notice that the retraction settings will be different depending on the fact that whether you have a Bowden setup or a Direct Drive setup. Implementing these processes will surely help you to get the best retraction settings and print the object just as you expected. To get the best retraction settings you can adopt one of the different ways. #Slicer for fusion 360 says material is too small how to#How to Get the Best Retraction Length & Speed Settings? Most of the time the retraction speed works perfectly at its default range but you may need to adjust it while switching from one filament material to another. It can also result in the filament getting ground and chewed up when the speed generates too much biting pressure and rotation. A distance too long can cause a decline in print quality because of that delay. It should not be too fast because the extruder motor will reach the next location quickly and the filament will extrude from the nozzle after a short delay. Retraction speed should not be too low because the filament will begin to ooze from the nozzle before it reaches the exact point. Just like the retraction distance, setting the most suitable retraction speed is necessary to get better results. Retraction speed is the rate at which the filament will retract from the nozzle while printing. 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. 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 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. 5 How to Avoid Stringing in Flexible Filament (TPU, TPE) What is Retraction in 3D Printing? ![]()
