Fixing Under Extrusion in a 3D Printer

In this episode I show you how to identify common issues that cause under extrusion in your 3D printer and how to fix them. This is very important when 3d printing miniatures.
UPDATE: The two side alignment screws on either side of the heat break need to be left in as the grub screw does not hold the heat break tightly enough and Creality uses the side screws as a solution to the issue.

You are the man. I'm not a beginner I actually have 6 printers the ender and Tornado included and I've been printing for almost two years now. I've came across so many of these issues over that time and had to figure out and fix them mostly by myself. I wish I had found your channel a lot sooner. I've learned a ton in the few videos I've watch of yours. Thank you so much my friend, your making things a lot easier for me and everyone else with these issues. You know your shit lol.

I've spoken with Creality and the 2 extra hot-end screws must not be removed, they are to prevent bending damage to the heat break, they also give additional stability to hot-end and prevent head crashes from destroying the heat break tube.

@abhijeet_ghosh 4 ай бұрын

A heat break is a few dollars, and many people (me included) run the hotend without the screws. I have never damaged my heatbreak even when crashing my nozzle into the bed. They are just trying to save their butts.

If you properly hot-tighten your nozzle, the heat block should feel immovable without screws.

I can't thank you enough. I'm new to 3D printing, purchased an Ender 3 Pro a couple months ago. Long story short I was having layer separation issues and other difficult to diagnose issues. I had narrowed it down to extrusion, but couldn't put my finger on it. Your video was invaluable, as my extruder mount had a hairline crack only visible from the underside after I decided to replace it with an aluminum one, per your comments. This coupled with a glass bed improved my prints better than factory. I couldn't be happier. Thank you!

Had a sudden under extrusion problem that was quite extreme. I thought I had exhausted every possible solution and was about out of ideas. Then I remembered you talking about heat creep and the cool side of the hot end. The only thing left that I hadn’t eliminated was the hot end heat sink fan. A small piece of melted filament was lodged deep in the fan that only came out after aggressively blowing out the fan. The fan was running just under normal speed due to the debris and it was creating a situation in which the filament was melting in the bowden tube in the heat sink area. With the fan fixed the extrusion issue was completely resolved. I was amazed at the dramatic difference in results due to a slightly slower fan speed. Thanks for all the great resources!

I'm so glad I found this video. I recently came across some printing issues, and I've tried re-leveling the bed and unclogging the nozzle, but now I finally know that the issue is under-extrusion. I thought I was going insane when I had spent 20-40 minutes leveling the bed, then seeing that the nozzle is trying to print in mid air. This has relieved so much stress for myself.

I’ve been plagued by under extrusion for quite a long time. It has kept me from being able to really enjoy my printer for years. After seeing this video I removed my hotend/ heatsink assy from the carriage, pulled out my boden tube and nozzle, and looked through the heat sink and spotted a gigantic wad of plastic that had formed in the hotend between the nozzle and boden tube. Cleaned it out and now my prints are 1000% better! Thanks for the trouble shooting tips!

Great video. Thanks for the tips. I have one suggestion: when you talk about the "cold pull" cleaning, specify that the temperatures you're quoting are for PLA filament. A raw beginner may not know this and try doing it with a material with a higher glass transition temperature such as ABS or PETG and get frustrated that it didn't work.

For me the issue ended up being as simple as increasing the print temperature on my old spook. A great suggestion that I didn't see anywhere else! This was after I had disassembled the hot end like a dozen times. Thanks again!

Sir, you are a master at this. When I bought my Ender-3 I promised myself not to mess around with upgrades and stuff. Just had an under-extrusion problem with it and your video is the best resource (by far) that I have found to help me. Based on your advice I upgraded the Bowden tube couplers and the extruder. In the end I think it was just tangled PLA that caused the problem but I am quite happy that I managed to do all this by myself with your videos and am confident it will save me problems in the long run.

Much appreciated - the video is so clear and thorough. My Ender 5 started misbehaving about 5 hours into an 12-hour print, and I couldn't figure out why. My current guess now is that I forgot to check for filament tangles at the start of a new spool. I was able to unwind/rewind a bunch of the spool to fix the new ongoing print, but I'll have to go in and properly resolve tangles afterwards.

This video was immensely helpful! The material was presented clearly and concisely without (as another poster stated) a lot of KZfaq "antics". Very professional. Thanks! I would add to others who are trying to troubleshoot this problem - I finally discovered that the filament guide lever (the one with the roller and spring attached) on my CR10s, WAS CRACKED! The plastic had cracked where the roller was attached to it so that the roller itself, HID the failure. The result was that every time I did something to stiffen the spring and apply more pressure to the filament "pinch" ... it would seem to work for a bit but the crack would flex giving me variable pressure and VERY inconsistent results. I now have an aluminum guide block to install :) BTW - when I removed the OEM plastic lever and examined it closely, the "guide hole" had become triangle shaped as you mentioned in your video. Impressive, considering I have run only a little more than two rolls of filament through it!

Great video, definitely put me on the right track for fixing my problem, even though it wasn't specifically mentioned.

Ender 3 is my first 3D printer and I went through each of those issues. I actually found a few of those issues lead right into another issue. It took me a couple of weeks to realize the filament gear wasn’t making complete contact and was slipping, the spring just wasn’t strong enough. Replaced that whole system with an all metal system. Ruined my first nozzle with in the first month before I got a consistent extrusion rate (at least enough to actually calibrate). I’ve got it running now ok. I haven’t really found a slicer I’m comfortable with. I switch back and forth between Cura and S3d. But it was your Cura profiles that really resolved a few slicing issues I was having (or better way of putting it, a lack of understanding). Great video, thank you!!

Ender 3, v1 You saved me. Between this video and a bit more digging I nailed it. I'm back to printing. I have been having issues since getting a glass bed, but maybe it wasn't the glass bed after all because I hit a point where my nozzle just wasn't extruding anymore. I was out of hope. Putting my original/stock bed cover back on did not fix the issue. -Disconnected Boden tubes on both ends, removed visible clog, sprayed air through it. -Heated up the nozzle, removed it, pushed a small Allen key through the top and sure enough POP a big chunk came out of the heat sync/nozzle end (with nozzle removed). -Put in a new nozzle to not take any chances -Used a tooth brush to brush the gear that feeds in the filament (with isopropyl alcohol for good measure!) ...Still no printing -Final step, I added 3 small washers between the spring and screw on the extruder. Photo of washers installed --> imgur.com/T2xA9E9 Next steps, I ordered a replacement aluminum extruder assembly and new connectors for the boden tube. I suspect that once I replace those I'll be beyond back in business and will hopefully future proof against this happening again. Thank you for this amazing video.

This actually is a very informative video. Great job, the PTFE tube not close enough to the nozzle was the problem in my case. It caused underextrusion and another problem, the filament started to build up in de heat block. Because of this friction the extruder gear started to slip, resulting in even more underextrusion.

To be honest, I kinda wanted these techniques to not work - especially the 90*c filament trick - to pull out gunk and burned filament from the inside of the heating block. Why?... because they are tedious - especially if you do a lot of printing. Unfortunately, the 90*c filament trick fixed my “under-extrusion” issue - so lol - I have to do it now about every 6 to 8 prints to fix “under-extrusion”. Although, since my 3D printer is a Geeetech A20M, and I am using ABS - I have to amp my temperature to 100*c to remove debris from the top of the heating block - using this filament technique. Now, when I remove the nozzle, I have to amp my temperature to 120*c - to remove debris from the bottom of the heating block - using a filament. As tedious as your trouble shooting might be - it worked for me - so thank you so much!!! Now I have to figure out how to fix under-extrusion on my “Qidi” X-MAX 3D printer - extruder on that one is attached to a heating block - so one piece. “Filament-pulling” technique will not work on that one. Thanks again!

I am still experimenting but as my printer is running I adjusted the screw located at the extruder and increased temp for 7 degrees and while the video is still going on, the sound of failed extrusion is gone :) I instantly subbed, and am looking forward to exploring your channel :) Thanks a lot!

Thank you, Sir. You have a very clear diction, pronounciation and lack of accent so that foreigners like me can easily understand even at very low sound volume. You can see for yourself that automatic subtitles identify 100% your words. This is quite rare on youtube, believe me. Seems like nothing, but it's not, a lot of youtubers have like 75, 80% of their words identified by the automatic subtitle service. This should be a warning sign for them to work on their pronounciation or accent because really voice recognition software is full of artificial intelligence, trained with various accents and pronounciations so that to understand as much as possible,. If automatic subtitles cannot cope, than probably the target audience would be very much restricted to natives only, or worse, from that specific region of the country or neighborhood. I enjoy your presentations as they have a very good balance of informative, usefull content presented in a logic manner.

Thanks for the tip. Prints were working fine for a long while. Had 7mm extrusion so I thought this may have been it. But previous printing sessions were fine. Noticed it was right after retraction. It wasn't melting fast enough (lots of humidity lately). Added 10 (then changed to 5) degrees more and that allowed it melt quick enough upon reextrusion.

Thank you for sharing your knowledge and tips. I am brand new to 3D printing (so new that my first ever printer is still en-route and yet to be delivered, ha-ha), so I am searching for every scrap of information I can find so as to prepare myself as I begin my journey down this 'rabbit-hole'...I've subscribed to your channel, and am working my way through your videos, and am thankful for the time and effort you have put into creating them. Your explanations and way of speaking is helpful to me as I find that you are not presuming that a viewer has a lot of prior knowledge, and so I, as a complete beginner, can understand and grasp the concepts. And thankfully you do not have annoying music and special affects which so many u-tube "wanna-be's" use...that in and of itself makes your channel stand-out above others in my opinion. Thank you again for the time and effort you've put into all these videos...I am learning a lot and am grateful. 👍

7:36 Thank you so much man, this fixed my under extrusion problem, I just need to tighten it up a little bit and change my nozzle temp to +10 (190c). I subscribe.

This has to be one of the most helpful videos out there for 3d printers. New to the hobby or a old hand you're going to learn something from this video, if not then you just weren't paying attention. Thanks for the video, it definitely helped a major head ache I was having with my cr-10s. Sub'd

Good stuff Tom, I totally fought that Cura 3.5 filament size issue. spent a week trying to figure it out because I had just started printing. I think you posted on FB about it and boom problem solved. Thanks for doing what you do.

Ha. This happened to me, too - I changed material and for some reason the filament diameter got changed to 2.85mm. The print came out with wire mesh sides...

Thank you so much! Living in Florida definitely added moisture to my filament but on top of that I'm about 3/4ths through my roll and the gear was having a hard time getting that tight wind to pull through. I upped about ten degrees and unrolled my filament a bit. I'm going to need to babysit this roll until it's end but plan on doing a few upgrades soon that will hopefully help on the pull.

Another super useful vid. I've been having some extrusion issues on my Ender 3 after a retraction so I'll try some of these suggestions. Also, after your last video on mini's I managed to print my first successful mini!

Awesome! We have a 'part 2' for our printing minis video coming in November :)
