    FINALLY someone is testing all hotends with a consistent method.... we badly needed this. THANK YOU!

      Agreed, there's only so far subjective tests can go, the "Look how pretty this disposable trinket is, good hotend!".
      CNC Kitchen does good tests as well, there thankfully are a few engineering minds out there that help it when it comes to pushing limits or getting the best consistency on results.

      @patprop74 I suggest the combination of hot girls and fast printers to achieve the maximum money throughput to keep the crazy fast printing going.

    • Giuseppe Antonio Nanna
      Giuseppe Antonio Nanna 3 หลายเดือนก่อน +3

      @patprop74 actually I sent a small donation as soon as I watched this video and I'm planning to do the same after each episode of this series.
      Because companies do not publish useful benchmarks anymore we need independent testers in order to make informed purchase decisions and award the companies who actually do valuable r&d.
      We have benchmarks for PC, cars, phones, audio equipment, even vacuum cleaners but not for hotends. Without them we are at the mercy of marketing and this is unacceptable.

    Very excited for this to continue. This could end up being one of the most important series of tests/videos in 3d printing. It serves at least 3 purposes. 1 it could help people tune their existing hot ends. 2 it could help people select what hot ends to buy, and 3 it could serve as a huge source of information for future development of hot ends attempting to improve maximum printing speed.

  • Malvix

    Excited for this series! Would love to see how a CHT nozzle changes the flow potential for hotends that could take it, to see how much could be pushed without an entire upgrade

    • MirageC
      MirageC  3 หลายเดือนก่อน +5

      Yes, once I have a few hot end tested, I will do one episode on the CHT's impact on those already tested hotends.

  • Gábor Tóth
    Gábor Tóth 3 หลายเดือนก่อน +13

    Finally, I was looking forward to someone to do such a standardised and detailed comparison for the hotends. My compliments. Please allow me to point out, that every filament type has it's own rheological behaviour characterised with the melt flow rate (MFR) or also called melt flow index (MFI), which is a standardized industrial method to test the flow capabilities of the plastic. As I have done a flow comparison between filaments myself with the Flowtesttool from CNCKitchen Stefan (and being in the plastic processing business for all my life) I know, that the MFR is one major influencing factor for the flow capabilities of the hotend. My advice is, that during the olympics it is important that you use the same filament, even the same batch if possible, as the MFI is changing between plastic batches as well. Otherwise the test results will be not comparable. Can you please indicate the actual MFR of the plastics you used for the test, just out of curiosity? PLA filament MFR values we can buy are ranging from ~5 to 15 g/10min. The difference in flow between MFI 5 vs. 14 on a Prusa Mini hotend with 0,4 nozzle is 11mm3/s vs. 22mm3/s when they reach 10% underextrusion.

    • Gábor Tóth
      Gábor Tóth 3 หลายเดือนก่อน +1

      @Olivier Vincent Yes, I think I understand now. Basically you want to copy the industrial MFR measuring method and use it to determine the real MFR of the filament. What I ment is only to compare the two batches of filament by looking at the curves which are already implemented by MirageC. If the curve is significantly different from the perivous one without changing the process settings (in this case the temperature), then you know that the filament has a different MFR - and can even know if lower or higher - and therefore the result of the hotend comparison will be not accurate. It's not for a quantitative analysis, only qualitative.

    • Olivier Vincent
      Olivier Vincent 3 หลายเดือนก่อน

      @Gábor Tóth yes that is correct what you are saying, but you have to do this comparison in the mm³/sec region where you are sure that the fillament that is leaving the nozzle is exactly at the set temperature. If your flow high the plastic will be melted,.yes, but not stable at the extruding temperaturemaybe 4 degrees lower or more... Or less.... You will only know if you could measure at the exit.of the nozzle... . For example take a super volcano and extrude at 10mm³Sec. Don't do that with a v6 since you are already in the rising curve/ limit of the heating element

    • Gábor Tóth
      Gábor Tóth 3 หลายเดือนก่อน

      @MirageC This is why your series will be a big help not only for every user, but in my oppinion the 3d printing industry as well. There is no standard test procedure for hotend flow yet. You said in the video very correctly, that the print speed is now limited not because of the movement, but the plastic flow. So the industry desperately needs a standard method to compare the performace in an equal way, and so the game rules are becoming equal as well.

    • Gábor Tóth
      Gábor Tóth 3 หลายเดือนก่อน

      @Olivier Vincent I cannot interpret fully what you mean, but the last sentence: "Then the only difference in pressure is because of the MFi of the plastic" tells me, that we are talking about the same thing here. We used this method with actual extruders producing medical tubes. If the extruder pressure rised or lowered without changing any of the process settings, it was an indication that we have to rise or lower the barrel temperatures accordingly to compensate for the change in MFR. Especially during charge changes. So the idea is to do the same on the 3D printer hotend. If you change nothing in the test settings, and run the test again, but a different spool of the same filament type and the force applied to the filament (extruder pressure) changes, you know, that the MFR changed and the flow test is not any more apple to apple comparison.

    • Olivier Vincent
      Olivier Vincent 3 หลายเดือนก่อน

      @Gábor Tóth well problem with this is that depending on the flow your filament is not equally warm. With the melt flow meter you wait 2min before you extrude so temp is all the same. If you extrude at let's say 10 % capacity of your biggest hotend and you then measure the pressure then I would say that the filament ists temperature is equal. Then the only difference in pressure is because of the MFi of the plastic

  • Justin Moritz
    Justin Moritz 3 หลายเดือนก่อน +3

    I thought your analysis of the cross section was really interesting! Very good idea to easily examine the elastic deformation of the filament post extrusion.

    Great stuff, looking forward to seeing the results. I think this could be a valuable resource even for those not chasing ultimate performance. For that reason it would be nice to see some other more modest hot ends included. For example, the Revo would be something I would like to see run through these tests, although I know it wouldn't be near the top of the leader board.

    Hey, absolutely brilliant video! I can't wait until new episode release, can't come soon enough! Brilliant presentation and I can understand it pretty well as I'm not an engineer. So many different data points your using and that's incredible for finding out different hotends for our needs, the amount of time and effort this requires must be pretty intense.
    Just wondering what schedule are you going to be releasing these videos? Once a week, month, day etc? I suspect you've done the vast majority of the data collection now and it's just the presentation to do now?

    Awesome! I'm looking forward to the rest! I mainly focused on the extruder, but the hotend is at least just as important, nice setup!

  • Griffin

    I would love to see a klipper feature which uses a rotary encoder for some kind of active flow compensation.
    I guess the hot end could be characterized, but it would be really tedious to do that at every temperature with every filament and flow rate.

    • aharkey1077
      aharkey1077 3 หลายเดือนก่อน

      @Condorman you are right, for some reason I swore the BTT runout sensor was JUST a runout sensor with no way to detect a jam but it appears it does. Neat guess I’ll buy one of those instead lol.

    • Condorman
      Condorman 3 หลายเดือนก่อน

      @aharkey1077 You mean the BTT filament sensor?

    • aharkey1077
      aharkey1077 3 หลายเดือนก่อน

      I plan on doing an encoder to detect runout and jams as that seems like low hanging fruit, closed loop control, while interesting, is a completely different can of worms.

    • Griffin
      Griffin 3 หลายเดือนก่อน

      @aharkey1077 it could do both. Maybe even detect potential nozzle jams before they happen.

    • aharkey1077
      aharkey1077 3 หลายเดือนก่อน

      I'd be more interested in a filament runout sensor that could also detect jams with an encoder

      @R M yes, ive been using a load cell for some parts of this, as well as an lgx which makes skipping harder.

    • R M
      R M 3 หลายเดือนก่อน +1

      Actually - measuring the force needed to push the filament into the hotend is one of the objective which is really reflecting what is going on into the melting zone.
      Most of the studies available here on TH-cam uses wrong approach of the skipping extruder (which can be a result of million things but the processes ongoing inside the hotend).

  • GrossGeneralization
    GrossGeneralization 2 หลายเดือนก่อน

    Nice work! One idea that might help: you could extrude onto a rotating drum to simulate the pressure profile during printing. That would allow you to measure the pressure and flow with the partial obstruction of a print surface beneath the nozzle.

    • GrossGeneralization
      GrossGeneralization 2 หลายเดือนก่อน

      @MirageC That makes sense - the data you are getting looks consistent enough to be pretty compelling anyway. Keep up the good work!

    • MirageC
      MirageC  2 หลายเดือนก่อน +1

      Yeah, i thought of that, but getting the drum perfectly centered, level and heated is making it a bit too complex for the resources I currently have in my possession. This being said, I did find a way to measure pressur in an effective manner during printing. Working on the video now ;)

    Speed has got crazy on these machines but I have 2 concerns: integrity/strength of the part and increased wear on the machine and what the increased ownership cost would be but its exciting to see how far this tech has come.

    • MirageC
      MirageC  2 หลายเดือนก่อน +1

      You are totally right. Printing faster needs to be matched with extra care to the print temperature and to the cooling mode. Once we figure out the maximum speed at which no quality loss is observed, we should focus on the difference in layer adhesion between this maximum value and slower speeds.

    Nathan Builds Robots 3 หลายเดือนก่อน

    16:46 Have though about this before, the unmelted core is real. Larger nozzle size is mostly just a way to let a larger semi-solid core pass through the middle, so its not the best way to increase flow rates for effective printing.

    Crazy excited. Love most of your methodology, I'd be interested to see differences with wattage changes in heater cartridges.

    • MirageC
      MirageC  3 หลายเดือนก่อน

      Wattage will mainly affect heat up time and will allow crazy cooling solutions. Given we are not exceeding thermal output capacity of a low power heater and that both units have been properly PID tuned, there would be no extrusion flow gain from installing a more powerful heater.

  • Billy Westendorf
    Billy Westendorf 3 หลายเดือนก่อน

    Very nice! This is just the kind of data I am interested in. Another thing that I think would be good to do is to test the melt flow index for different brands and different materials. It would be interesting and helpful to know how a high melt flow index affects the printing speed. My theory is that you can upgrade to the biggest and best extruder, but if you are trying to force a low melt flow index material, the material is going to become the bottleneck. I work at a plastics company and I am very familiar with how much the melt flow index matters.

    • Billy Westendorf
      Billy Westendorf 3 หลายเดือนก่อน

      Maybe a good TH-cam video on the subject will give them a hint! I have seen a few filaments advertise the melt flow index but mostly that spec is not available. The highest advertized I have found was 12 melt. Most of them range from around 1 - 8 melt. But I don't know how realistic it is without testing it. I think somewhere around a 20 melt would be interesting to see what happens.

    • MirageC

      Totally agree with you! I cannot wait to see some Filament manufacturers to embark the 3dprinting speed wagon!

  • Kilian Gosewisch
    Kilian Gosewisch 3 หลายเดือนก่อน

    I'm also very excited to see where this is going. I'm not really interested in the "physical" part because my hotend is stationary on my quantum delta printer.
    I am really curious which hotend you will find the best with the shortest meltzone. My current hotend is rapido with a supervolcano nozzle which sticks out at the bottom. The bottom part is covered with a chc pro heater and a 0.5 cht nozzle. The ridiculously long meltzone probably is the cause for my relatively poor pressure advance calibration. But this is just a guess and we all are always looking for an upgrade :P

    May I suggest the haldis k1 hf, round ceramic heater. I have just started playing around with one of these. It's very impressive. One piece nozzle,heartbreak,heatsink similar to the Revo but superior mechanical design .

    Great video, we need more proper science in the comunity.
    Btw, you dont want to use moment (nm) as your measurment as this presumes the force comes from gravity.
    You instead want to use moment of inertia (kg*m^2) = mass * distance squared. This is what determines how much rotational force (and this vibration) your printhead will cause under acceleration.

      @harry loud What length of melt-zone would you use?
      The nozzle length only, or the nozzle and the section that is screwed into the heat block or event the heat block itself being a path for the melting zone?
      As nowadays, to increase flow capacity, for similar nozzles, the heat break tube is also a pre-heating melting zone, depending on its material employed, very variable from manufacturers and can increase highly that characteristic. It could be interesting to evaluate it.
      An example would be E3D V6, nozzle length is 12.5mm, heat break tube into the heat block, between 4 and 5mm, that would bring the melting zone to 12.5+4mm = 16.5mm? compare to an MK8, where the Bowden tube goes against the 13mm long nozzle, that would be its only melting-zone.

      @MirageC Mabye length of meltzone is a good metric?

    • MirageC
      MirageC  3 หลายเดือนก่อน +1

      @harry loud Well, we need a certain balance between mass and flow capacity. If mass was the only criteria, we could get a super light hotend with barely no flow to score high on the chart. Anyways, I am sure that looking at the numbers as we go, something is going to pop out loud and clear in termes of what makes a good hotend VS a bad one for speed/quality printing.

    • harry loud
      harry loud 3 หลายเดือนก่อน

      @MirageC Even still, mass is the more important metric as this is primarily a linear system

    One more thing is important to know about the hotend: how much filament can be extruded very fast.
    I'm pretty sure that any hotend can extrude almost all the melted filament which is already well melted inside the nozzle.
    So it is almost the volume of the nozzle internals. You can reach let's sat 100 mm3/s for 100 millisecond or so with no problem (the only thing is needed is to slowdown afterwards to let all the cold filament to reach desired temperature inside the nozzle)

    Have you considered the effects of the different thermal conductivity of the plastics used? Obviously it will vary due to formulation but I believe PLA has the lowest thermal conductivity, followed by PETG, and then ABS with the highest. I’m not sure to what extent this variation might account for the different pressure profiles you see in the data.

    Would love to see how clones compare to the real deal in these tests. I'm sure there is some level of degradation of quality, but is it offet by being 1/5 the price?

    • MirageC
      MirageC  3 หลายเดือนก่อน +1

      I am not planning to measure clones right now due to the simple fact that they should be within reasonable margins of the real deal and second, they are clones... ;)

  • Gábor Tóth
    Gábor Tóth 3 หลายเดือนก่อน

    Please allow me one correction for the part: swallen melt phenomenon. The swell of the melt after leaving the nozzle has two main reasons.
    Firstly it is connected with the flow speed distribution of the melt in the cross section of the nozzle path. Inside the nozzle the speed of the melt directly next to the nozzle wall is normally zero, so it sticks to it. In the middle of the cross section the melt speed is the highest. In between there is a bell-like shaped speed profile. When the melt is leaving the nozzle, this speed distribution of the melt becomes instantly flat (equal speed in the whole cross section), because there is no more nozzle wall to stick to. To this almost instant cross-speed change the melt reacts accordingly and forces the melt naturally to take a swallen form.
    The second reason: plastic is basically a bunch of entagled molecule chains / macromolecules / polymer chains (the lenght of the chain can reach few million links). Like a microscopical dense cotton wool ball. If the melt is being deformed in one direction (passing trough a small nozzle hole), the molecule chains are going to be unidirectional, they will be more or less parallel to each other instead of entangled equally in any direction. It requires energy to get to this parallel-form (squeezing the melt trough the small hole by the pushing force). When the melt is leaving the nozzle to free air, this squeezing force is gone and the macromolecules are going to get to their lowest-energy shape again, which is entangled (due to entropy). When this happens, the melt is changing the shape accordingly, it gets swallen. This is also called the memory effect, the plastic wants to get to it's original form again. This is partly the reason, why you have inner stress in your 3D printed part. And this is the reason, when the 3D printed part is heated up over a certain temperature, it is deforming. The filament wants to get back to it's original shape.
    And to couple this back to the MFR topic: when a melt is more viscous (more thick, equals low MFR), it requires more energy to push trough the small nozzle-hole, the speed profile is more sharp and you bring in more energy to make the polymer chains (more) parallel, it will swell more. With more flow speed even more. A high MFR plastic is behaving the opposite way, you will barely see any swell. By the way, the MFR is directly connected with the length of the polymer chains. Short, entangled chains can be reoriented more easily, long chains are harder to reorient.
    Cold core extrusion exists (the core of the melt does not reach the melting temperature), but I dont know if it has an influence on the swell. Probably yes, but this is not the main issue for this penomenon. In my oppinion, what you see when you cut the extrudate is probably the not uniformly crystallised plastic.

    • Gábor Tóth
      Gábor Tóth 3 หลายเดือนก่อน

      @MirageC Nothing to thank for, I am glad to be able to help to understand plastics better. I was looking for a link for a more detailed description and pictures, but did not found a good internet source for this topic. I only have my books as a reference, but all written in german.
      If it helps you with your hotend olympics even just a bit, I am happy, because your work is very important for the community and 3D printer industry.
      A little related to this, but rather off topic, which I want to add to this conversation because it bothers me a lot: there are a couple of myths about the filaments in the 3D printer community in regard of the physical/mechanical properties and choice of material. My advice to everyone is to read, try to understand and compare the datasheets of the filaments. Any information is there, free of charge, it takes just a little background learning, how to understand all the data. Many of the PETG and ABS fans would be surprised, how "low-level" material those are. My message is, that if a plastic is more expensive and is harder to print, does not necessarily mean, that it is better.

    Science B*! I think this will make history and difference for whole 3d printing community and industry. Hopefully we will see even better hotneds at future after you have cracked down key factors of good hotends. Anyway I recommend that you will also test to cut one CHT extruder screw part and put it in to longed heat block with another CHT extruder. Or cut normal extruder and use it as pre heater with CHT.

    nice video! Great data for a future printer build for work (...can't afford another for myself or expensive upgrades...), but it's also funny to see how the results of the genuine V6 correlate so much with the results I'm getting on my Aliexpress clone V6. Frankly, that's quite an achievement for the cheapo part!
    Let's see the later videos to know what I might be getting if I ever end up going faster, heck even my own machine with a wide line width and taller layers can benefit from a good hotend anyway.

    • Kalvinjj

      @MirageC One day... One day I'll have the money to just go with originals and not bother with hit or miss clones, probably gonna be with a Revo or such.
      I hope this day ain't taking long!

    • MirageC
      MirageC  3 หลายเดือนก่อน +1

      I would not expect a V6 clone to be miles off from the real deal. The simplicity of this unit makes it difficult to miss. No special coating or complex machining. Unless you have material inclusion in the aluminum raw mat or very bad machining tolerances, the results should be extremely close yes.
      The difference between clone and real resides in the amount of support you want to give the original inventor who has put his heart and sweat at developing the best product for your needs.

    Wow, great data. 3D printer scientist. What is the frame rate on the high speed video? That fan looks like its going to bust! Can you just rely on the hotend moving rapidly through the air to produce enough airflow/heat transfer?

    • Nathan Builds Robots

      @MirageC looking forward to your theory on heatsinking. I think you are on the right track!

    • MirageC
      MirageC  3 หลายเดือนก่อน +1

      Printing PLA with opened enclosure on a large part could potentially generate enough air flow to avoid using fan. As a matter as a fact, I did it a few times using the Nova. The only problem I kept having was when preheating the printer and then tune stuff or work on it, then I would forget about not having fan and would systematically get clogs. This being said, I am now evaluating a theory about the heatsink playing a larger role than what we think.

  • Bo Pedersen

    FANTASTIC series idea ABD firnat!
    I believe you have struck 3D printer TH-cam gold with this! On a side note, I don't believe the V6 like E3D is their flagship. Up until very recently, I believe it would have been the humera, but the V6 officially being the unofficial gold standard!! 😅
    As funny as that may sound, I actually rather mean it, because I don't believe any other print head m, since the reprap movement started, has been more heavily copied than the V6.
    However, I could very well be mistaken -
    Is there anybody in the know that could update this line of thinking with a better, more copied (and flat out ripped off if course🙄) hotend?
    Either way, as a fellow cannot, I salute you! I was only introduced to you a couple of years ago but always look forward to your next video.
    And as for flattery?
    I incorporate as many of your ideas as I can into my own builds! 😁
    ...Because, as they say, imitation is the most sincere form of flattery, correct?

    The swelling that happens is also related to "die swell" which happens because the polymer chains get get stretched out in the hole and after contract again which makes the whole thing short and thicker.

    • MirageC
      MirageC  3 หลายเดือนก่อน

      Yup ;)

  • Tessie spotter
    Tessie spotter 3 หลายเดือนก่อน

    One thing I've always wondered is: Does die swell affect a line's ability to stick to the underlying layer? Die swell is the result of compression of a fluid through an orifice and subsequent expansion after it exits. Therefore, since the printhead is moving while extruding (sometimes very fast), is it likely that per a given point on an extruded line, the plastic does not have time to fully expand once out of the orifice before the nozzle has moved away from its position, resulting in it not being squished down onto the layer below?

    • MirageC
      MirageC  3 หลายเดือนก่อน

      It is a question that gets affected by many parameters. For example, I could print a filament that has descent amount of flex using a big nozzle at higher than recommended temperature. The non melted core could be bent into shape while the external layer be super hot to guarantee good interlayer adhesion...
