- In this video i'm going to show you how to safely remove a hotend blob from your 3d printer without causing any damage.
Firstly, don't panic.
It can be quite easy when you see something go so obviously wrong with a print to immediately start pulling on the melted mess or cutting away parts.
This is nowhere near as bad a problem as it looks and, if you are careful, you may get away without replacing anything and be back printing within about 10 minutes.

I have been 3d printing for close to 5 years and cannot believe that I ran across your channel just recently. The common sense (which seems to be lacking everywhere) you exhibit is nothing short of refreshing. Love your channel.
Yet another perfect video.
Right to the point.
No dramatization, no shilling 3d party products.
Thankyou so much, i was so shocked and so panicked when i saw my 3D-Printer looking like this this morning. This helped a lot! Thanks!
This really helped me. I was printing overnight and a blob happened. I tried to peel it away but the thermistor came off and I had to buy a whole new head. Thank you!
I wish I had seen this video before I bought 3 hot ends after my prints kept coming un attached. II even bought a new printer! When i happened again on my new printer, I saw this video, and these methods worked a charm. Thanks so much for sharing!!
your bed might be causing the problem as there is not enough adhesion, to avoid it happening again you could try increasing bed temperature to secure the print down
Great video. I woke this morning to a massive blob on my hot end. Thanks for the tips here I was able to remove it with the only casualty being my silicone sleeve
Fingers crossed that I can do this tomorrow
The effort you put in your videos is jaw-dropping. Great work man!
Thanks for the support 👍
You're the best. Clear and concise explanation and it worked. I'm an archi student with a deadline tomorrow that woke up to this after setting up an overnight print - on a borrowed printer. Panicked. Cleaned up and just started again!
Awesome! Really glad it helped👍
I had my first 3D printer for a few months now before this happened and I was so worried when this happened, I thought I'd have to replace the whole unit. It looked like a terrible mess with the clog but thanks to you, I fixed this and now I have resumed printing in less than 10-15 minutes as promised. Thank you for making this video. I really appreciate it.
Really glad it helped👍
If you chose a temp. slightly below melting point (for example 180 pla), it still melts, but still sticks together enough to get it off in one piece without wiping.
Short, sweet and to the point I love it
I have no idea how it took so long to find this channel. I own a QIDI X Max, a Prusa MKS3+, a CR-10s pro v2, and now an Ender 3 V2, which might be my favorite machine thanks to your channel.
The Prusa is great, but thanks to my Ender and your videos I feel like I actually understand these machines.
Awesome 👍 Welcome to the channel Josh🙂
A lot of effort went into this one! And poor hotends :) Thank you, very informative.
Man, ran across this issue during the first week of having my printer. Unfortunatly couldn't heat up the handle since even though i checked the initial layer this happened to me for a large portion of the print. Observed the beginning of the print to make sure it was adhering fine then went to bed. Woke up with this giant blob all over my ender 3 s1 plus and the printer refused to preheat the nozzle (likely due to how much of the filament showed up, it even ate two cables pulling one off the mechanism slightly but hardening enough that I can't plug it back in.
After some fiddling I ended up just ordering replacement parts, once I verify the replacement parts working fine I'll go back and try fixing the broken extruder myself as a learning experience.
Thanks for the video man, will note this knowledge for the future. Just a warning for those using a heat gun - there is a large heatsink (at least on my extruder mechanism) that ended up permeating across and lifting one of the cable connections. Should be an easy fix once I get the blob off but just a warning for those in the future. A bit worried since it did seem to mesh together some of the smaller cables near there but plugging it in the mechanisms those are related to are working fine, will just make replacing those individual parts harder if needed.
To imagine all this damage from me not releveling after purchasing one of those adhesive sheets and putting it on the print bed. My laziness cost me a near $200 replacement parts fee qq.
Thanks for sharing your experience. Sometimes there can just be no easy recovery and you have to replace some parts as you've had to.
Good grief! now that's commitment, flooding your printers with filament just to demonstrate how to clean the Quatermass level of blob on a brand-new printer. Well impressed.
Thank you this was such a lifesaver
this is still great, thank you
Great tip, thank you
Great video, helped me recently.
I had this happen a few times now over the course of 6 months, it ruined the hot end so much I had to fully buy a new full hot end.
The thing that made me do so was because after fighting to remove the filament blob and doing all that you said.
The problems for me was the hot end was so encased that all the tiny gaps and screw holes and even the tiny holding screw below the heater cartridge was full of the now hardened once melted
filament such that no cleaning could get out the melted filament of the tiny heater holding screw!
So I could not remove the heater cartridge at all as the Allen key could not get into the tiny screw to undo it and the mess even was wrapped around the thermistor cable too and would have broken the wires if I had tried to remove it?
The melted filament just made it impossible to remove without the wiring being damaged. and yes a hot gun was tried after I got the hot end off the back plate and placed in a small metal hobby vise. So I now lost 3 hot ends. I had to replace them and change the bowden tubing to Capricorn and had either a all metal hot end with the bi-metal throat or us tight fitted Capricorn tubing down t the nozzle to stop out flowing hot filament. The new problem I now got is almost as bad?
I have silk pla's and every time I tried to print with them on any of the now 4 printers I got each time the silk pla flow fine and print but soon block up the hot end such that I am forced to strip it fully down to clear out the blockage as heating more and such don't remove the blockage.
And I even had a silk pla that I started at the stated temp on the nozzle on the help info box label and it would not even flow so I tried again at 5 C higher and so on, then I get it to flow at a 220 C temp and walk away and come back and see it put down 3 layers and then totally blocked up the hot end. Only my silks do this, my normal pla's and petg's are fine.
Really a pain.
fr similar thing just happened to me. Pretty sure it's lodged deep inside the mechanism in my case and it even pulled some cables. Lesson learned on my part but it does suck. Ended up also buying a replacement part. Thankfully I have an ender and replacement parts seem readily available (although their listing of what printers are supported isn't quite accurate from what I can tell)
Is there any solution to this? Or do I have to just expect to cough up $30 every other week for a new hotend?
Great video, my Heat block ended up being threaded. I think by the heat. I have Cr-10 Smart Pro. Are heat blocks interchangeable. Like can I take a heat block from my Ender 3 V2 and place it on my cr-10?
Thanks so much!!!
Thank you sir , 👍✌️
Omg this helped so much! If you can take out the nozzle and heatbreak and pull a bit of cloth on wire or with your plyers that helps too. I only use PLA but have a spider v3 on my enter 3 and it leaks out the top and bottom so I am trying to tighten it at 270c and I only print at 200-210 c
Ricky your videos are amazing, I am new to 3D printing got an Ender 3 S1 for Christmas. I watched your videos to learn so much before I started and as I made mistakes, I wish that I saw this one before I boiled my hot end in water to clear it. LOL Thank you for the great information you provide.
Ah, yes, this would have been easier. Hope you are up and running again now.
@@RickyImpey Let it sit overnight and it is running great. Again, I have learned so much as I go through your videos, thank you for sharing your knowledge
yes someone made the vid, thank you!
This helped me a lot for cleaning mine up! Although instead of a towel or shirt, I just use paper towel. I'm not sure why that wasn't really covered as good/bad for the use-case, but it seemed to work well for me as an alternative material!
Thanks! You saved my bacon.
Thank you👍
Hopefully you'll get to my question I could use your help, what happens if the filament gets all around the heatbreak area , I have a voxelab Aquila v2 and there is the tiniest gap between the nozzle and the square part and twice already I have gotten filament that goes up and I think is getting in there going through and around the heat break coming out of the top of the square and just replaced it twice , would this work
Thank you but my thermistor was dammaged so i cannot heat up the pla. What do I do then?
So I know its a bit late but lets say that you panicked and tried to remove it but now the heat measurer cable gets cut and the blob is still on the printer what should I do?
Wow I've never seen that before but I'm new to this
Mine shorted once the blob happened now I can’t even get the wires removed to put in a new hotend. What should I do?
Got a blob and it encapsulated the wires to the heater and thermometer on the hotend (as well as completely encapsulating the sock), had to spend hours gently trying to clear it away but broke all the wires, it's also up between the heating element and the cooling block and filled up the screw heads so making it difficult to pull the heating element off to clean up. Grrr. Ender 3 V3 KE.
I've had this happen on my ender 3 max neo, got most of it off but there's some still stuck in there I don't know how to remove the fan cover
Hi, Thank you very much. My Printer produced a blob 2 days ago and I was able to clean everything up with your instructions. I just have one problem, it still stinks when I heat my hot end up. What do?
The smell with most likely be from any remaining filament. The only real way to clean it off is wiping it with something like a rag when the hotend is hot. Be careful not to burn yourself!
@@RickyImpey Thank you I tried exactly that, and after a couple of hours the rest of the stench disappeared.
This kind of hotend is very easy to clean, but my printer is a sovol sv06plus with a hotend that is not so easy. The temperature sensor cable is so thinny and they will brake very fast at the try to temive a blob. I have ordered now my 3. hotend. 😢 the blob came at first to my printer because the Z Level was wrong, so i keep an eye on a good z leveling. The 2. was broken because the adhesion of the bed was not enough, so i buyed an adhesion spray and now its good. The 3. Get broken because i had layershifting and the print goes on in the air. This thing drives me crazy. I have so much problems with my printer and im running out of options to solve it.
Brand new to 3d printing and this has happened 2 times and this time it’s smoking I can’t tell if it the electrical part or the filliment
Question when your wiping the hot end with the rag how do you stop the thermistor from blowing since you removed the fan?
As long as the thermistor and heating element are both still attached to the heat block then there is no problem. The heater heats and the thermistor tells it when it is at the correct temperature and to stop heating.
"The sock" had a damage. It took the better part of an hour to get it all done. Other than that success!! (I was surprised how well the cotton rag cleaned the mess)
Hi Ricky, i kept my printer to print over night and woke up to the same issue, i paniced and tried to cut off the dry PLA of the nozzel and hotend and by mistake i broke the nozzel and there are 2 white electric wires that got disconnected :(, im lost on what to do now its my first time owning a 3D printer and this issue occured on my 3rd day, the printer i have is Xvico x3s. do i need a new hotend assembly? i can email you some pictuers of how the hotend looks like now if you want.
Many thanks
Oh dear, it sounds like you may have cut through the thermistor or heater wires. This also means you won't be able to heat it up to clean off the hard filament. You could try gently heating with a heat gun but be very careful of any plastic parts around your hotend. The other option is to replace the whole hotend and wiring.
@@RickyImpey Hi, thanks for taking your time and responding to me ! i ws able to heat the the the extruder, however, the thermostate wires are disconnected. and the nozzel is broken :(
Today I was lucky. I preheated to PLA and blob just pulled off.
i didnt have a big print and i checked on my thing and there was a blob, I pannicked so i stopped it quickly and gently ish pulled it off, now theres just strands that I need to clean up
when I saw it I pannicked and pulled it off when i came to check on it and it was still hot
I wish I had found this video a week ago.
Had a massive blob and removing it made my Hotend completely unusable.
Oh no! Unfortunately it's not uncommon to damage parts removing a filament blob. At least you will hopefully have an easier time removing it if it happens again.
This did not pop up I watch multiple video from 7:00 am searching different things like nozzle melted material around it help, how to fix, how to remove, how to take apart none ever showed this video I get this video after I pull on it after I try to get it off I fucking TH-cam and it’s algorithm, is there way to buy parts or did I just ruin my printer ?
The Sock Is A LIFESAVER my printer came with one and HOLY CRAP the blob got everywhere when finally got it off the sock was destroyed but the nozzle was just fine
Yes, they are a great sacrificial part to save the more expensive bits.
I used a toothpick to clean the narrow tricky bit. Be careful though, you don't want to break the toothpick
hello, how can I contact u?
Hi, my channel email address is in my 'About' section if you need to contact me. Alternatively, I offer any help I can here through comments as they can be read by others who may have the same issues.
Don't Panic... but if your thermister is damages, you screwed... just toss the whole thing
