How to Fix Stringing on a 3D Printer

[@blackredroll]

Thank you so much for pointing it out that tuning should begin from temperature and then retraction. I had severe stringing when printing small parts at regular PETG temp (235) and retraction (5 mm). I decreased temp to 215 and retraction to just 2 mm and it was IT! Part printed beautifully but a bit weak, too little layer welding. I increased temp to 220 and retraction to 2.5 mm. Now it's perfect! No coasting, no wipe, no extra prime. Ender 3 with 1.9 mm ptfe. Thank you :)

5 years later and still useful!

[@Chris7uk00]

It's not just caused from temp alone!, it can be caused by having your travel speed too slow for non printed moves which allows the nozzle to ooze filament because it's going too slow!!! when it shouldn't be printing anything, the faster it moves to it's next location for printing the less chance it has to ooze filament!, if you don't believe me try it for yourself with your temp tower!!!!.........

[@Franto85]

Great video, thanks ! Export the G-code, save it, replace the file, pull out the sd card :D Man, I love it! That's gonna become a great channel

[@lkcustomsau324]

I know I'm a bit late to the party, but you are an absolute legend, and the way you put this video together is great, and thank you.

[@kalmanf]

thanks, however the criticism on this video is valid, however I learn from my mistakes, and I will be posting in the future a better video about this, and fix things I didn't do well here. thanks for your support my friend 😊

[@shigowbt]

nice video... but it could be shorter cutting the "process of saving the file"

[@abdelrahman3287]

my advice not to retract before wipe just leave it 0% to wipe and retract directly not to make the seams notisable and less stringing too. and thank you very much for these information it really worked very well I really appreciate your hard work.❤

[@kxdsh]

that part where you kicked the dog really confused me as i thought you actually did

[@boboscurse4130]

You need Octoprint. :)

[@thedeathshadowking2794]

It doesn't work for my printer for some reason [ender 3 pro (marlin 2.0)]

[@bushabix2676]

Worked perfectly for my HATCHBOX PLA filaments, along with the right temperature, stringing now is nearly non-existent, thanks!

[@toastcrunch9387]

I like how my printer defaults with the settings you recommended and it strings like hell.

[@wurstelei1356]

Might be wet filament. If I lower the temps like in the video my nozzle instantly clogs...

[@B1G_ChUnG5]

This was an absolutely immense help! Thank you! Stringing is completely gone!

[@lucasfalcao3d]

Thank you so much for this help, best result I've get from A LOT of testing.

[@lucasfalcao3d]

Now I need a video "How to Fix Blobs on a 3D Printer" 😅

[@brandonb417]

Have you conducted this test for ABS? I just got a new printer (I've been only doing resin up to this point) and its stringing a bit, but since its an X1E I'll be printing primarily out of ABS.

[@amedeekingchef6552]

Dry filament is also a good factor.

[@practicalguy973]

I wonder if more heat will be better layer strength as it can melt into itself more. I'm currently printing at 203C for PLA and getting some stringing.

[@kalmanf]

Haven't had issues with layers not being strong enough. But this MAY be a problem if you were to use a different filliment than mine. You can always print up a few sticks in different temps and test the strength 😉

[@practicalguy973]

@@kalmanf I haven't broken anything yet but layer adhesion in general is a lot weaker than I'd prefer for parts than need to take a lot of force like a clasp or hook. I've learned that just printing them in the right orientation so the layers are not taking the force is all that I needed! There are some good examples of testing I found recently where you can see a wide variation in strength depending on a bunch of settings like seen here where some layers let go with as little as 12lbs of force. I'm just trying to push it to the hottest I can so the pla melts into itself more ensuring I dont get random weak parts when its a part that needs to be strong. kzbin.info/www/bejne/nJO2gqmAf8-qaLM

[@kalmanf]

Yes I understood that. But like you said rotating a print is a great way to make it stronger (depending on the model). P.S. Don't put CNC Kitchen on my channel. LOL JK, that guy makes great content you can learn from!

[@MM.MischiefManaged]

Im trying to print the temp tower, but prusaslicer keeps overring the temperatures with the filament temps? What am I missing?

[@ripmax333]

but will the lower temp printing make the 3D printed parts weaker?

[@sausagefingers714]

and faster the better for retraction speeds is not true either

[@heikoheusel3638]

Very nice explanation, with the same Settings my print is a dream. thanks very much.

[@GaryMcKinnonUFO]

Cute dog! There's a few more variables at play here, i've rarely seen stringing that bad at those higher temps such as 200-230, especially with your lumpy stringing, perhaps there was a flow rate problem at the time ? Thanks for sharing.

[@mcrsrm]

Export the GCode, Save it, Replace the file, Pull out the SD Card, Put it in the Computer, Drag the file into the SD Card, Replace the Destination, Pull out the SD Card, Put it back into the Printer, ....and Print. Yes, seriously. I can't afford a Prusa MK4 yet, but when I can... my MK3 is going in the garbage... or maybe printing the files that I print a lot and never make changes to. I hate this process of 3D Printing so much, some days I just don't want to do it and I don't print anything. I can't wait to try this fix when I get home! (and replacing ALL my saved prints with the new setting, replacing each GCode in my SD Card one by one...)

[@37Kilo2]

Going to give your settings a go, because I have been experiencing stringing on my recent prints. Thanks for the vid.

[@khaleedairil1975]

Playing with temp is the easiest thing ive done. No hassle for extra tuning

[@jessestirland314]

YOU ARE A GODSEND!

[@josephastrahan6403]

I read that putting the retraction more then 1.0 (you did 2.0) can cause problems later when filament moves into the 'cool area' and clogs it up. Do you find this to be true?

[@kalmanf]

No, to answer your question. I have noticed a problem at 3 though. Maybe I don't have problems because of my printer model.. Thanks for your input though, you are awesome for watching the whole video 😊

[@josephastrahan6403]

@@kalmanf Yeah no worries :). I am using the Mk3S, which printer were you using? It looked like the same printer but wasn't sure.

If you're not going to use octoprint save your time by putting sd card in computer then export to sd card. No need to make extra files. I hope these settings get rid of retraction thanks!

[@KLP99]

Faster retraction isn't better. That's a myth. I set my retraction to 1mm and speed to 20mm. No stringing. Done. And I have a cheap printer with direct drive. If you use a Bowden tube, set retraction to 4 or 5 mm and speed to 20mm.

[@s3bio]

Your retraction speed is too high. Your slicer can't perform it correctly thats why it is red.

[@GTJay]

Yup, the saving and moving file process is just as annoying in video as in real life.

[@colincampbell3679]

Call the Dog Protection Unit... he kicked his cute doggy!

[@ThomasWilent]

please get a pi and use octoprint, it'll change your life. Also more doge

[@kalmanf]

Lol, i got the Pi, i just never set it up.. Should i make a video setting it up or nah, just do it?

[@ThomasWilent]

kalmanf yea I think it could help people it's actually easy and makes printing way easier. Also explore the tons of plugins in there too. Octolapse alone needs more videos on setup, I.e using during case mode

[@TotoGuy-Original]

Why dont you just save the file directly to the sd card then you can save a step lol

[@JaydenLawson]

haha the annoying walk to get that damn SD card - I need to upgrade mine with wifi!!

[@MaNwEMeLoDyAM]

process of saving the file was necessary to see how he kicks his dog :)

[@kalmanf]

For some reason the dog sounds like a cat when he gets kicked 🐈🐕

[@henmich]

But low temperature makes your layers de-laminate more easily.

[@kalmanf]

Yes, it will do that. However for pretty much all my prints its been more than strong enough. Or try to print high temp and get rid of stringing with a blow dryer 😋

[@staniobadjo]

I gave you thumbs up for the effort , but the part with exporting the g code and writing on the sd card is anoying ...don't do it

[@loglandocomando7525]

I had to put it down to 70 but it worked!

[@kalmanf]

I think you mean 170. I don't advise printing so low. if you get stringing on 180 and up then you have moisture problem in you PLA. so, throw your filament into a dehydrator, on 50c for 8 hours. this works for me.

[@loglandocomando7525]
