A bi-metal heat break, consisting of copper threads and surgical stainless steel tubing is a pretty interesting concept that can potentially add quite some performance to your 3D printer. Let me show you how I was able to more than double the extrusion capability of my Ender-3 what happened when I first cheaped out and bought a knock-off part and how I was pleasantly surprised when I spent the money and got the genuine one from SliceEngineering! Let’s find out more!

Heatbreak is a pain in the butt to change. You might have to apply thermal grease, you might need a wrench and pliers. Id much rather just have multiple hot ends. Honestly, if it was easily available id rather just have multiple hot ends on hand, and just change them out for differently sized nozzles/heatbreaks/etc

I got my bi-metal heat break from Trianglelabs, works extremely well and the press fit is pretty solid. Dropped 8c on my heatsink and haven't exceeded 40c on it even with both hot ends at printing temp. I have noticed that I was able to print very large extrusion widths very quickly, and for only $17. UPDATE: Benchmarked my max flow rate with a bimetal heat break, copper 0.6mm nozzle, copper heater block, BMG extruder 3:1 gear ratio, and pancake stepper at 0.5amp RMS in DD config. The final results were around 25mm/s^3 cubed, incredible for a non-volcano V6 hotend.

Went to Slice Engineering and purchased the Copperhead Heat Break for my Ender 3. I received it yesterday and quickly installed it. The results were amazing. I printed a curved Lithophane using Silk White filament and the backside was almost smooth as glass. The picture was amazing. Previous attempts were stringy loose layers and inconsistent as well. Your video was well done and your research was very much appreciated. This has changed my printing quality, I highly recommend the Copperhead Heat Break. Their website has a chart to help you get the right one for your printer.

Great video Stefan! I really appreciate that you showed us how you removed your old stock heat break and re-threaded the block, these are useful details for first time hot-end surgeons. One comment however: since the heat block was flush with the heat sink with the knockoff test; this likely cause a significant amount of heat creep and could have been the culprit for printing artifacts. Granted this is in part due to the shorter length of the knock off, however even the genuine part had some spacing issues due to length. I may be wrong but I think the heat block / heat sink screws could still have been used as a spacer.

Thank you for this video, knowing this could make things much easier in the future with my Ender 3. I just experienced many days of jamming after 1.5 hours with 245°C on my Ender 3, the solution was that the original heat sink has thicker fins than the aftermarket I bought (aftermarket but still a good company, just not original). Everything was the same and I was going insane on troubleshooting. If I would've had this heat break I would possibly not have experienced my problems, if/when my original heatsink will break then I know I have to have this product to successfully print with PETG temperatures. Thanks again!

I bought the same style of heat break from Spool3D made out of titanium for the Ender 3 stock hotend. It worked great for CF nylon but clogged constantly with PLA even when oiling. I coated the heat break with a high temp thermal paste and it finally stopped clogging with PLA. I finally switched to the Micro Swiss direct drive and all metal hotend kit and never looked back. Lol works perfectly. Just did my first TPU parts without any issues.

If you have that kind of inconsistency, then that flow is too high for the hotend + extruder setup, so you could limit the flow so that every part has the same "low" flow rate, but this is just one of many, that can "help".

Honestly I think that the main reason for that small extrusion rate on the ender 3 is because the ptfe tube is making the length of the heated section (melt zone) half as much as it normally is in an all metal hotend. v6 lite also has reduced extrusion rate. this one is basically just the nozzle as the heating zone.

I've been using the triangle lab bi metal for a while now and have to say it works great. with dry filament I can get a lot of material down to 1mm retraction on bowden and I can now print at 150mm/s on pla. I have yet to try higher speeds but I think I could get some serious flow out of it. not to mention this is a very cost effective way to upgrade to all metal allowing you to print higher temp filaments.

Yesterday, I printed several big part in PLA with my good old standard E3D V6 2.85 with 0.8 nozzle at 21mm3/s with no troubles, no under extrusion and excellent layer fusion. Extruder is à simple "reprap like" geared with hobbed bolt. Simply played with head temperature in prusa slicer with layer custom gcode M104. Making temperature change from 230° in thin parts to 245° in big area layer (100% infill).

Great insights, Stefan!

What a coincidence! I tested a cheap bi-metal heat break just two days ago (an all metal V6 clone). Clogged hotend approx 14 hours into the first larger print. After disassembling the hotend the heatbreak looked ok, but filament would just not fit through. On closer inspection I saw that the inner tube wasn't actual a tube but a rolled up metal sheet with a slit. That slit delaminated (I guess from the temperature gradient) from the wall and one end of the metal sheet pointed inwards. Filament no longer flowed. Went back to my titanium heat break I had no issues with.

10:27 - I think the shorter "knock-off" heat break may actually be a "Kraken" or "Chimera" heat break made for a clone E3D or Volcano hot end rather than for a Ender 3. If the OAL is 20.5mm, it's a Kraken/Chimera heat break. The Ender 3 one has the same threads and barrel diameter but is considerably longer.

So I've had my copperhead heatbreak in my Ender 3 for a few weeks now. It ran for about a week in Bowden configuration and I was able to cut my retraction from 5mm to 2.2mm. Bowden tube gap cured and print consistency improved. So your results confirmed I didn't really get to play with volumetric flow before I put it in (almost) direct drive with a fake bondtech BMG and a pancake stepper with a printed mount. I'm still tuning flow rates, mostly I'm really enjoying how well it prints flexibles. I'm going through my stack of designs I wanted to print in TPU and cranking up the flow rate. The PrusaSlicer profiles top out at 2.5mm3/s for you and I'm currently riding 3.5mm3/s with Amazon basics TPU (95A I think?) and cranking this up for every print and now going to have to make changes to the linear speed limits for the basic 0.2mm ender 3 profile as I can't ride the volumetric speed limit everywhere... that's pretty cool for a slow melting filament. My tuning for PLA has gone as far as getting retraction down to 0.2mm with some PLA and running a printer default of 0.5mm which has really boosted my print speed on complicated parts. I need to put some time in tuning the PLA speeds now knowing I can push quite a way on volumetric flow before I have to worry.

My experience with a bimetal heat break from biqu is a bit mixed. Performance is amazing, i have no issues with print uniformity, like in the video. However, the tube is a bit loose and does rotate a little bit, even tho it shows no indication of ever coming apart. A bigger issue is that long retractions, overpressure or pulling the filament out, without first pushing it a millimeter in before, results in molten plastic climbing in the cold zone and clogging the nozzle.

I'm relatively new to 3D printing but I have 35 years of experience in technical work on office equipment and I received a working Ender 3 Pro for free and have learned how to use - maintain - and modify it. What I have discovered is that if I remain at relatively slow print speeds I have no problems but when I speed things up the gremlins come out to play. I think the Ender 3 product line is great to learn on but if I was to get serious about 3D Printing I would invest in a Bamboo Lab P1P and move to the next level . Still I'm having fun using and troubleshooting which is what I've done all my life. 3D Printing is relatively a complex hobby - the design CAD programs are an art form onto themselves - learning to use and make adjustments on the slicer program is also quite involved - then there's the printer itself which requires maintenance and knowledge. It's a great hobby but thank God for all the KZfaq videos which are so helpful in understanding problems and solutions. Your video sure explains a lot of things.

Interesting video Stefan! I got a Titanium V6 heatbreak for my MK3S to avoid PLA jamming because of the custom 'notch' the standard heatbreak uses for the MMU2. You mentioned known downsides for a titanium heatbreak, what were you referring to?

Welcome to my grounds Stefan I am using various knockoffs bimetal from China for over a year now in my twin nozzle water cooled heatsink, and yes they are manufactured without any quality concerns. But I managed to find a way to make them work well,I fine tune them phisically (which I would expect from the producers to do but I guess the just don't care) A) the PTEF tube inlet need to be deburred and eventually countersunk enlarged to hep the tube slide in, a 2 mm cone fillet or chamfer does the job,takes a few seconds to do it. B) same think at the filament inlet below, but here a one mm fillet or chamfer is enough, I sort that out with a small conic router bit run once clock wise for a second or two, than anticlockwise for three or four seconds to give my fillet a shine so it does not grip on the filament. You see how some small things can ruin a good concept in a potentially good product? BTW, it took you a hile tochange that head each time... lol, using my snap in place manual tool changing setup that takes 3 mintues, assuming you have more than one heatsink at hand, just fit them in different configurations,and when needed swap them in seconds. One last thing, PLA adores sticking to metals, hence all metal heatbreaks be them one metal or bi metal are not a good option for PLA, Stick tot the PTEF sleeved heatbreaks for that, makes life easy, no cloggs, no jamms. On the other hand PETG, Polycarbonte, Ultem have not such issues, I am still to test HIPS in bimetal setup, will find out next weeks.

I got my Trianglelabs stainless steel bi-metal heatbreak for my Neptune 2 last week. I installed it with a Trianglelabs copper plated 0.4 nozzle and it's a dream. Besides the other upsides I never experienced skipping or grinding since then. The filament flow (with ABS) is just crazy and seems to have no limit. I got a malfunction a few days ago since my Neptune 2 is in a box right now to print ABS and the board overheated, which made the extruderstepper drive at a ridiculous speed. In a few seconds there was a great mass of ABS extruded. I was really happy to see that performance boost, even though i experienced this malfunktion :D The Trianglelabs stainless steel bi-metal heatbreak (and the copper plated nozzle!) is worth every cent. Wouldn't go for the titanium one, since it seems it has no copper part in the heating section.

Hi Stefan! I was wondering if you would suggest this upgrade over a CHT nozzle. I am currently starting to print a bit faster now that I got into Klipper and the only thing keeping me back is the thermal performance of my ender 3. I have switched to direct drive but now that I tweaked and upgraded everything but the hotend under-extrusion is more apparent.

Mine fell apart at the lower thread portion. The center came right out leaving the threaded portion in my heat block. I was pretty disappointed. Big flaw of these. Made sense when I took it apart as a leak had developed and everything was properly tight. Mine were bought on Amazon for my sidewinder x1 v4 , looks to be the same ones pictures.

One little thing is, that the lower part of the heatbreak is a bit longer than the original one from e3d. But some tweaking with my PINDA fixed that.

Upgrades like this seem to be worth it even if you're not going as fast as possible because of the thermal performance which means less heat where it shouldn't be, either on the hot or cold side.

It would be super cool if you could do a video talking about the different types of tests and prints you use to calibrate and test your printers. I'd love to know what you do to get such clean looking prints.

Your are the empirical guru just subscribed because I have learned so much from you!. I am on mission to learn all things possible to optimize print time and quality and find all your post very informative. I wanted to suggest another topic a roundup video. If a good heat break helps melting performance, and CHT nozzle + adapter (your other video) also helps, what results do a unified system of these two combined approaches produce?

This really got me thinking (I like to push my Ender 3 to 5-7mm^3/sec at least for infill) : Shouldn't it be possible to compensate for the reduced flow at higher speed in software? Or possibly by measuring the actual length of filament pulled into the extruder and realtime feedback to compensate for the loss of extrusion efficiency (I imagine a Sensor similar to Thomas Sanladerers filament diameter sensor but measuring filament travel)?

I love your testing protocols. Would it be possible for you to compare the ender with bimetallic heat break to a Phaetus Dragonfly hot end? The hotend does come with a bimetallic heatbreak, copper heater block and nozzle. I would be genuinely curious to see a 1 to 1 test, especially given I'm currently using one in my Prusa Mk2.5s.

4:55 i occasionally keep getting that skipping thing happening. is it always down to too fast extrusion? because for me it seemed to only happen when a print starts printing lots of small sections of infill with retraction, so it pushes and retracts the same section of filament multiple times causing it to gouge the filament, to the point it was so bent it increased the friction in the tube, that happens multiple times and eventually it's too hard to push through and it cant extrude anything and just keeps grinding the same spot of filament. could it be that its a problem that is started by too fast extrusion and the combination of retraction makes the print fail? Would be good to find a solution for this

Did you get any stringing problems after the switch? When I switched from a heatbreak where the bowden tube goes down to the nozzle to one with a second PTFE tube a liner I noticed an increase in melting speed but I also suddenly got stringing. I guess that with an even faster melting hotend the stringing will become even worse.

I actually purchased the knock off "Swiss" all metal hot end from Triangle labs which uses a Ti heatbreak, and am yet to fit and test it on my Ender 6. I have been reluctant to test it as it has taken me a long time to get acceptable prints from the E6, but I'm getting there now, so I think it's time to move on. The quality of the Triangle lab parts, from my past experience, have been exponentially better than that of the usual chinesium cheapo knock offs. Usually as good as, if not better than some of the parts they're copying. Their nozzles are incredible value. I'm hoping the Ender 6 upgrade it will give me adequete TPU results, but think the Ender 6 is in urgent need of better part cooling than the, frankly lazy, duct design that's provided with it.
