They work on filament types, such as TPU, PLA, ABS, and PETG. Here are a few surefire ways of getting rid of stringing and making sure it never bothers you, or your prints, again. It also involves keeping your nozzle and filament clean. It entails adjusting your temperature and print settings. You can solve stringing by adjusting your retraction settings. 8 Steps for Fixing Stringing on Your Prusa i3 Mk3s: This causes stringing and oozing when it feeds filament again.Ī dirty nozzle will also develop blockages if you aren’t careful. NozzleĪ dirty nozzle is more likely to form clumps of melted filament right outside it. This solid string gets dragged to the next layer, ending as a string. Printing slowly ensures smoother print lines.īut it can also allow time for the leaky filament to solidify. Keeping your nozzle at temperatures that are too high results in stringing. This excess filament is dragged to the next layer and glued into place. Having a nozzle that is too hot for the filament means that more filament melts and leaks out. Retraction is the most important factor in eliminating stringing. It is also how long it takes for your printer to retract your filament up the extruder. Retraction is how far and how fast your extruders pull back the filament. Here are the main reasons why stringing occurs. Stringing is a printer error that can happen to the most seasoned printer user. When left unattended, you may need to scrap your whole print because of stringing. This leaves ugly strings sticking out of your print and may ruin its integrity. With too much pressure in your hotend, filament leaks out of the nozzle rather than getting sucked up the extruder. This is more common with Bowden extruders (not your Prusa) but can happen on Prusa’s, too. Without the proper retraction settings, the hot nozzle will continue to leak filament, which turns into strings. It happens when your nozzle travels some distance without printing. Plus, stringing can make some prints unsalvagable if not managed and contained. Of course, better is if it doesn’t string in the first place. If you have a bunch of stringing on a print you can fix it by cutting the strings with a nipper or hobby knife. It commonly happens when you haven’t fully calibrated your slicing software. This causes strings of filament to stick out of your print. This string gets dragged to the next print layer and sticks to it. Stringing is what happens when your printer extrudes melted plastic unnecessarily. We’ll also go over some easy ways of ensuring it never happens again. Let’s go over what stringing is and why your Prusa Mk3S is tringing. You’ve become a victim of printer stringing. But what’s this? Thin spider webs and tentacle-like strands of filament surround your print. You got yourself a Prusa i3 Mk3s+, one of the best printers on the market. So, you’ve decided to invest in a 3d printer.
