Love a good cold pull :P Also what can work amazing is to use intentionally moisture damaged nylon next to 'steam clean' the remaining crap out of the nozzle. Like seriously if you let it get wet it pops spits and builds up pressure in the nozzle. It's SO satisfying.
YES! I've only done that once, long ago, on accident. I need to do it again. Plus, it's super easy to do!
Steam clean? My dad would freak out
As I just posted, string trimmer line works well too, with the added benefit of it usually being quite full of moisture, so you get the steam cleaning effect as well.
@@mattelder1971 Thats funny. I was just thinking about that while watching this wondering where I was going to get a nylon string like that. I have some "twisted" trimmer line as well. Maybe turning it around and back and forth in the nozzle will have an "agitation effect" or a "swiping effect" and clean even better :)
@@mattelder1971 What size line trimmer line would be appropriate for a 4mm printer nozzle?
I love these basic videos. It helps everyone. Please do more of these!
Just want to say I'm very new to 3D printing and had no idea what a cold pull is, this is by far the best tutorial I've seen. Subscribed to you! I love the energy and how well you explain things. Made it so easy to follow
I remember the first time I learned this trick. I was extremely excited. Made my printing life so much better. You are still one of like 10 people that have one of my custom faceplate haha.
Joel just feels so personal, like he cares about my happiness and stuff. Thanks Joel, I WILL get something tasty to drink. :)
When I tweeted a number of 3d printing youtubers he was the first to respond back to me.
And I replied here too!
Some heroes don't wear capes :D
Papa Joel, tell us a 3D printing bedtime story
Quick note to add: if you have a hot end where the PTFE tube goes ALL the way down to the nozzle (such as a CR-10), even if your firmware allows you to go to ludicrous temps, you should throttle it around 235c.
Meh, I'm printing PETG at 260°C with this and the bowden tube looks fine...
Eh. Even the UM2+ has a PTFE coupler between the hot end and the Bowden tube that needs to be replaced once in awhile from heat exposure (after1000hrs print time usually). Needs to be replaced more often with higher temps. Not like a cold pull takes that long anyway.
I took an old Bowden tube and cut an 2inch piece to guide my filament when loading hotend. Then after hotend cooled, I removed the tube, reheated hotend and did a cold pull. That way I didn't need to worry about guiding filament or burning my Bowden tube.😅
Joel you're a legend. I have literally been suffering this issue for the past week and this just diagnosed and fixed it. Thank you so much!
Thanks for all of the great info Joel. This helps me out a ton. I'm a noob at this & would never have thought this was an issue until I actually started developing problems. I'm pretty sure you just saved me a bunch of failed prints.
One thing I would add...I would move the print head to the corner and be wary you are not pulling upwards too hard to damage the metal rods. I've never used Nylon for my Atomic Pulls, just PLA...heat to 220, press filament in, then cool to 90C and pull. Rinse and repeat as needed. I'll have to see how Nylon does as a comparison! :)
In work we used PLA to cold pull a fully cloged UM3 BB hot end (with PVA) it takes few pulls and in the end it was like brand new.
Yes, this is the correct way... the way it is explained in the video is not the correct way.
The Explorographer There is no 'correct' or 'wrong' way. Of course, it works with PLA, but if you have some Nylon, thats better. The type of material doesn't really affect the cold pull. It's the action that does the magic. The type of material just changes how well a material works to clean out another material, based temperatures
Well then we can just agree to disagree. I am going by how it is shown to be done right from the Ultimaker site. Do it however you want.
What i dont get is why he heats up the filament before pulling it out. Why call it a cold pull when you heat it up? I Also always use pla and either let it cool down all the way or heat it to 80C because it gets really flexible but it will pull everything out even the little bit right inside the 0.3mm hole.
Great instructions Joel! I had bought some "cleaning filament" for my M3D Micro as it clogged ALL THE TIME. But never really knew the right way to use it. What you showed makes a ton of sense.
I have done cold pulls on my Ultimaker Original and UM2+ for a long time but using nylon adds an extra dimension that I didn't think of before, so gave it a whirl. Couple that with the constant pressure while cooling, it works really, really well!
Nice one, Joel; adding a new twist to an essential technique! #highfive
Thank you for this! I've read plenty of pages on how to do a cold pull, but seeing it is always helpful.
Joel, I love you. I've been having trouble lately and the last print was plain awful. So, I bought 1 roll of nylon filament (I though "what the heck, let's give it a try") and after about 10 pulls, it is now printing as good as new.
Thank you so much for this.
Thank you! Perfect timing! My Qidi X-One printer just clogged last night and I was having a lot of trouble finding out how to unclog it without taking it apart.
As a newbie to 3D printing, I found this extremely helpful (and entertaining!).
Thanks for an excellent step by step detailing of the process. Guess it's something we should be doing periodically anyways.
Thanks for the how to Joel. This is the kind of stuff i love even though i knew how to do this already.
Great tip!! Always good to learn new techniques to clean blockages and even some good ol preventative maintenance 😀
Perfect timing, having some issues with my Prusa I3 Mk3 and came to TH-cam to research this very thing!
Hi Joel I will be getting my first 3d printer in December and I feel that your channel is preparing me for the frustration and solutions
Thank You! I've been sitting with a clogged extruder forever. I looked up how to do an "atomic pull" and was thoroughly unimpressed with the results. You're technique seems much better, and I'll give it a try so I can get back to printing toys for my kids.
Thanks, Joel! I have yet to get my first printer, but this is the first time I've encountered this idea. Yay for learning! #HighFive!
Thanks Joel for the tip, I hab also this special problem, but I such for a really good step by step tutorial, good job👍🏻😊
thank you so much, i had to try this while my printer had paused a print and it worked :D didnt want to wait another 2 hours to print something that was almost done.
Wow Joel this was super Helpful, for someone who has just gotten started I'd appreciate more of this format
I don't even have a filament printer, yet this was very interesting to me! Surprisingly, I still get asked a lot of questions about filament stuff, so always appreciate having more knowledge on hand to share when I can! :)
welbot wouldn't it be nice to have a 3d printer with an "autoclean" feature? Hope manufacturers take notice.
@@jorgeespinoza3938 actually it looks like it would be pretty easy to write a piece of gcode for it. would work especially well with direct extruders. I wouldn't be surprised if such a gcode already exists
Thank you so much. I have never understood how to do this. A visual guide made this misunderstood method easier to understand.
A little hint, if (like me) you don't normally print in nylon, and therefore don't have nylon filament around to do this, look for a small pack of string trimmer line at a home improvement store or the garden section of Walmart. You can usually find a small roll of it for just a couple of dollars. Be sure to get ROUND line (it does come in other shapes), and make sure the size is one that will fit your extruder (.065 inch line works well since it works out to 1.65mm, just under the normal 1.75mm size of filament).
good to know
Nice video Joel. Good idea for alternative methods ...
I use cleaning filament (eSun) which has a little gritty feel and seems to help scrub the insides as it moves through the nozzle. I then set temp to 100°C and let sit for a few minutes just before slow pulling.
Huge help! I’m always learning great things from you!
Thank you for sharing and helping me learn in my 3d printing endeavors.
I actually needed to do this for the first time today. Perfect timing :D
Am new to 3D printing so yes, I appreciate this. I'll order some nylon.
A cold beverage sounds nice…I think I will indulge while engaging in this practice. Thank you! Still learning everything with 3D printing
Great video. I successfully used this method before. Work like a charm.
Thank you for sharing this! It really helped!
Just got 7 year old printer for pennies. This video cleared biggest problem i had whit it (after rewiring controlbox😅).
Thank you for your 5+ years old video!🎉
That’s great news! You’re welcome:)
thank you Joel, this is exactly what i needed to see
Great video mate. Put it on my watch later playlist so I can always come back to it for refresher.
Bacon jalapeño jam?
You've changed my life and now I'm on a mission to find such a thing
This is just what I needed! Thanks so much! Life changed!
Great stuff, thanks for sharing this!
Quality video, nice job.
Thank you!!!! This was an awesome lesson... please keep on teaching!!
I occasionally find myself frustrated by random clogs in my Prusa i3 MK3 and after being benched for a month -- and fearing that a complete teardown and PTFE-tube replacement was in my future -- I thought that a cold pull might help, so I watched this video. I turned up the extruder temp to the max (295C, IIRC) and when I inserted my regular PLA filament, noticed that molten filament was flowing, so clog problem solved! :) While I may do a cold pull down the road, it just didn't dawn on me to really crank up the temp to unclog the printer! Thank you, Joel, for making such clear (and helpful) videos for newbies like me!
Oh, I was going to say that you listed the steps in your video and I'd find it even more helpful if you listed those in the description (or had a link to a page containing same), so we short-term-memory-challenged folks can use it as a checklist during the process. Thank you!
Great info, especially for people newer to printing.
Well presented and very useful. Thank you.
Excellent video - thank you! My first printer (Ender 3) has just arrived 20 minutes ago too! Happy days...
Nice!
Watch out for wear on the filament intake; that 90 degree bend is harsh! I suggest your fist print be a filament guide.

This one looks quit nice, and uses bearings for a smoother filament path: www.thingiverse.com/thing:303550
James Laine Excellent! Thanks for the tip and the links - very much appreciated! 👍🏻😎
I had not seen this method using nylon, good idea . Thanks
Thanks Joel, great info.
Thank you! I'm new to 3D printing. On forums I occasionally read the suggestion that someone should do a "cold pull" on the printer and the rest of the folks on the forum all nod like we all know that means. NOW, thanks to you ... I know what that means! Thanks Joel!
Amazingly some searches on the internet for “cold pull 3d printer” gives you loads of results.
No need to wait for a spontanious TH-cam algorytm to present you with the answer.
Love the video Joel! Quick side note to Sean, when Joel was talking about jam, I was sad that there was no SpaceBalls reference. "Jammed, Raspberry!"
12 minutes. awesome. helps with my stress right now.
This was not remedial for me! This was so helpful! Thanks, 3d Printing Nerd!
Joel. Love the videos also love the Rock, Paper, Scissor, Lizard, Spock shirt.
Thanks for sharing this. I need to do this. I suspected partial clog, based on the last print. Now I know how to clean it out. Thank you
I have had super success with esun cleaning filament. Rescued a nozzle after multiple cold pulls have failed. I was about to throw away the nozzle. Came out loke new. Ran around 10 cm of cleaning filament through the nozzle then did a cold pull using the same cleaning filament. The cleaning filament cold pull is at room temperature. Amazing stuff
Thanks, Joel - Just what I needed.
Decided to do a cold pull after having seen this video. I am currently waiting for the hot end to cool down and am enjoying my cold beverage! :)
Nice tip !
I don't do it exactly the same ... My method differs in only 1 point : I don't re-heat once it's at the desired temp. With nylon, I let it reach 120°C or so and then pull the whole stuff. Works like a charm.
also works with PLA, going down to 90°C.
Loved the Sesame Street moment "cold pull" , another good video thanks for sharing. Have a great day. God bless
great piece of info. I didn't know of this techniques until this video.
I've always wanted to know what a cold pull was! Thanks joel!
Good stuff! More like this in the future, please.
I’ve read the term cold pull so many times but honestly was afraid of asking and looking dumb. Thanks for the video!
Thanks for watching!
Good to know that works lol, I've been doing that with PLA for a long time and has worked flawlessly ;-)
I have a different method but same principles, while it cooling I just keep jamming it back in and out cutting off the tip each time until it won't melt anymore.
I love the homemade look of the ultimaker.. looks like some one in jr. high school made it.
great content actually showing what happen when you have a 3d printer and how to fix it,
Probably the best cold pull video ever. Also, looking for a followup video on this where we get to see the Full Joel Cold Pull. Lastly, those subtle little inserts from Sean might be the highlight of videos like this :D
Thank you! I try to spice things up here and there, but I'll never be as spicy as bacon jalapeno jam. :)
I subbed when I saw you're in WA. I'm in Kent lol. Thank you for this video. I think I have this exact problem. Not a full jam but partial blockage.
big thanks for explaining this, I got a lot old filament out of my nozzle! /Henrik
Having a clogged nozzle was the worst experience ive had starting out. It took me FOREVER to get it right, although once i realize cleaning the nozzle is very important everything came together and my life changed for the better lol i no longer get frustrated and give up on my 3d printer. it still is a process to have it clean, the cold pull method is something id have to try for myself!
#3DPrinting101
Thank you so much for this video! I've learned a lot!!
Thank you for the very well explained reminder. :)
Thanks! Very good video for a beginner like me.
thanks a lot your video helped me solve my jam , and i even found out(thanks to you showing me the cold pull) that my printer came with a tool to use on the jams
Glad I could help
Im liking these kinds of videos Joel!
Thanks for doing this.
your the only person how helped me clean my nozzle thank yo soooooooooooooooooo much man!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Thanks!! Great advice
Very good video! Thanks!
Thanks Joel I was struggling trying to figure how the cold pull works
Perfect timing on this video!...
I remember my first jammed nozzle, back when I couldn't find replacements. I was printing with ABS and was getting all kind of tension and build up in my hotend. I took the nozzle off and let it sit in acetone overnight to unclog it! 😆
Stephen Zura now that is an idea I like! Screw putting force on your z-axis... Just soak it!
I've done this before and just end up with a bunch of gooey abs still choked in the nozzle. Had to keep agitating and rinsing it out with acetone several times. Maybe that plug was extra bad, but it seems like a cold pull could do just as well and maybe a little faster.
Unfortunately, Acetone wont clear out PLA, etc., only ABS
I think this was great. Thank You.
Joel, thanks. Something I had not learned yet.
It's good to have videos like this how about a video on maintenance for 3d printers good example would be what kind oil is best on guide rails.
Thank you for your help
Wasn't remedial for me. Defined the problem well and presented the solution. Was perfect for me as I'd heard of the technique but didn't know how to do it. Off I go to give it a go.
thanks for the infor. I learned something here.
Thanks Joel!
Just had my 4 week old Ender 3 V2 clog up after about 100 hours of printing (last 3 projects were over 20 hours each). It clogged just about 3 layers short of completing the last model (sigh). Between the Creality video and this one, I should be able to get running in no time. Thanks!
Been a while since i saw some good content Thank you
I preffer doing it outside with a heatgun.
With it clogs i just jam in a new nozzle and then clean it later. I also give it a few brushes with the steel wire brush till its all clean too
thank you Joel, i didnt know about this problem..
Is there a way to search topics of your videos. I think they are great and I often need to research a particular topic. As an example, I want to know the ins and outs of printing with Nylon. Thanks
sweet info, been doing this for years. One thing, actually I've found things like Nylon aren't the best. Reason, they release at higher temps, so lets say the PLA you are trying to clean out is actually liquid already before the nylon releases. Honestly I've found Flexables (TPU TPEE) work the best as you can let it get near room temp to do the pull. Everything is somewhat solid and when you pull it you'll hear a satisfying POP and everything in the nozzle gets yanked out.... nothing gets left behind.
Thanks for sharing :-)
Good demonstration :-))
Thanks. Your the best.
Thanks so much it worked!!!
