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

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.

5 years ago I introduced 3d printing to MirageC and now THIS!!!! I'm very proud of what your accomplishing and keep up the work, you are well pushing the boundaries of 3d printing!

excellent video! 👏😎 looking forward to your next discoveries!

I'm very excited to see you doing a video series like this. You're the kind of thorough the community needs.

So much work has gone into this! Love the outcome! Was worth this! Crazy amount of data and detail! Hats off! 🤠

This video is amazing in its quality of engineering thought! Such a great value for 3d printing community. And great example of how to organize engineering research process and glimpse into what physics is about - learned a lot from this video! I’ll be rewatching this time over time. Great job MirageC!

I'm looking forward to seeing the next episodes! Your projects and videos are amazing! Thank you for your contribution to the 3D community!

holy crap. I LOVE the amount of detail youre putting into these tests. This is MORE than a 3d printing channel.

One of the best videos on 3D printing I’ve seen in a long time. No oink.

The quality of this video is incredible! So much info presented in an extremely clear and logical way. Just the 3D models alone, goodness. Well done!!🎉🎉🎉

This is incredible. Too often people point to intangible aspects of a part when recommending it or not - you’ve brought it back to my wheelhouse of introducing a consistent and repeatable process with data to back up the answers! Can’t wait for the Next one!

Thank you Mirage, from the bottom of my heart, for letting the data be free, as it should be! Long live open source innovation!

This is great work. Love the insane attention to detail, data capture, visualisation, analysis and explanation. Really great work man. Subscribed!!

My god you're taking this in a serious and scientific way, such a good work, you earn us a lot of work thank you so much for your intense work

I have been waiting for this! I cannot emphasize this enough, this is AMAZING. The amount of work here is crazy, i can't wait for the rest! I'm sure i speak for many in the community when i say: BIG thank you for all your continued contributions! Awesome work, will be very useful for all of us going forward!

This is gonna be AWESOME! Best of luck and I'm looking forward to the results!

actually so excited for this series, nice to have some really care and approach it in a standardized scientific manner

The best video quality in the topic, i hoped so much to see a real tests to be put out in any review and finally i saw them. Also, i laughed a lot from jokes about 2m/s extrusion and 1g conversion for average "3d printing" auditory. My respect for yours work. Definitely remember to donate smth after the war

What a return! Great to see you back, Olivier!

What an amazing series. I loved every second of it. You're going the extra mile in every aspect and we (the community) can't thank you enough for your hard work.

Amazing what You are doing, you are just answering all my questions i have with high speed printing, making a vez3d clone and im struggeling with the heated end. I donated some money for doing awesome science, thanks for your time and keep doing great work!

So cool that you take the time to do these tests. I really appreciate it, thank you.

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!

Wow, this must've taken a crazy amount of work! Super interesting, I'm curious to see future results and tests 👌🏻

Great test! Excited to see the next one

Wow. I cannot wait to see future episodes! Your findings are astonishing, seeing how close the 15.1 mm3/sec you measured is to the 14.1 mm3/sec that E3D rates the V6's maximum melt rate at...

A very professional test comparison work done👍👍👍. Awesome details, remarkable CADs, lots of data & graphs 💪. Thank you very much for sharing your wonderful work💕

Wow, your work is amazing! This analysis is more complex, complete and well explained than many scientific articles. Thanks for such a great job. The relationship between temperature, flow and pressure is really complex, but your analysis explains it very well

Been waiting for this to come back for the past year!

Cant wait untill next episode !!!! First time when im donating someone for this crazy job you had done

This is the most important 3D printing series in a long time. Thank you for doing the legwork!

13 min into the video. this content is insane! i really appreciate you as a content creator

This is a very thorough data intensive approach to the subject. Thank you and looking forward to this and learning more about this critically important component of 3d printing.

There are no words for that how amazing work you did!

Rewatching this now that I know a little more about the tech and I gotta say the shake you added to the "Dong" was a hilarious addition that totally flew over my head the first time I watched! :D

Best review I've seen ..I look forward for next one!

THIS, is the kind of videos im looking for when planning out my build. very well done.

Just discovered this! This is awesome. Cannot wait to watch more of these

So much data!!!! Thank you, I love it. Very excited to see the trends that start to form.

You're simply the best man! I like the way you approach the technique. I like your printer project too.

My man, this is an insane amount of work. Fantastic.

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

wow, what a task. I really appreciate your work and wait anxious for the next episode!

Love IT! This could be the definitive quide on which hotend to buy for a particular use for quite some time.

This is fantastic! I can’t wait to see the rest of the series

This is spectacular! I'm eager to see the results and how this all shakes out. A huge resource for open source 3D printing.

What an incredible amount of work you're setting yourself up for!

This is exactly what I've been looking for that the internet didn't seem to have. Lets Goooo!!

Excellent format, looking forward to additional episodes.

Look forward to the rest of the series, nice work :)

This is the most scientific thing related to 3d printing I have ever seen, amazing!!!!

Incredible video man !! You da best !! Thanks for doing this for the community. I know how much time and work you have put in this one... It is very well done and documented and very professional, bringing science in. Hats off to you my brother. You deserve a big bottle of rum!! Everyone should be buying you a paypal beer :)

I was just looking for some mosquito hot end alternatives or what was the latest innovations I should be looking at. I don’t normally check reviews from random channels I’ve never heard of. And in the rare cases I do, I almost never watch the whole thing, and don’t think I’ve ever subscribed. But I was so thoroughly impressed by this video (aside from the opening that almost made me leave from the overlapping audio) that I had to subscribe. Very well thought out tests and an incredible amount of thorough and considerate work went into this and that certainly earned a sub from me. Well done!

A very professional movie and it's a pleasure to watch, lots of graphics effects added and explained very well. You do things right got a lot your experience and you put a lot of work into making this movie, thanks for it.

Amazing stuff. Can't wait for the other episodes.

Absolutely Amazing Project. I think this kind of data like the "Filaween" Series by Thomas Sanladerer, or all the testing done by CNC Kitchen, or the "#SpeedBoatRace" "Speed Benchies"; even just all the amazing calibration/diagnostic prints people have designed and posted online are seriously what push the movement forward. Seriously Amazing Work, This is Pushing Your Channel to Another Level, and no need to rush things, This Will Be Well Worth The Wait !

I like the methodology of this and appreciate the empiricism. Looking forward to the next in the series.

Great stuff. Cant wait for the next part. I am starting a new printer build and this will really help me in selecting the hotend.

Amazing work @miragec i love it! Keep up the good work! This goes so much further then speedy benchy printing video's. Stuffs becoming a science this way. Merveilleux!!!

Loving it bro :). Glad you’ve spent the time getting it right !!

That's quite a project. Good job! Very impressive!

Dude I'm getting into 3d printing and this has been one of the first videos about the matter I've seen. Is the community always like this? Focusing on variables that affects the printing, getting loads of data... Are you guys secretly building a 3d printed rocket to take over the world or something?? Impressive stuff👏👏

Insanely useful information, I have never hit the subscribe faster.

Wow , Great work , and yes lots of time , Thanks For your great efforts !

Thank you very much for doing this for the community.

Fantastically Detailed and Nerdy Kudos for TopGear reference

I’m looking forward to see the result of all these hotends, great job thus far

Ayyyy finally it's out ! 🤩

great to see some proper study behind this. now I know for sure 220 is the sweet spot for PLA and that PETG prints faster, things I had observed but wasn't completely sure. Cant wait for the next videos!

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.

Great work. Thank you for your efforts.

Great stuff!! 👏👏 tks for sharing :) looking forward for the next videos

Amazing work has already been done 🙂🙂🙂

Can’t wait to see the full series!!

Dude, that level of data gather and analize. You get yourself a subscriber!

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.

Very cool. I’ve been looking for help setting up flow rates for my mosquito magnum, can’t wait for that! Cheers

j'ai pas d'autre choix que de te lever mon chapeau pour tout ton travail ouffff et hop un petit Don... continue comme ça c'est des personnes comme toi qui font avancer le 3dprinting!!!!

Ayo as a french Canadian I congradulate you on the script. It shows you really spent time to spell check and get the proper definitions

Pretty awesome 👏 props for the scientific approach.

amazing video explaining important phenomenon in 3D printing and crucial to understanding bottlenecks.

this is going to be the gold standard for hotend testing 👍👍👍👍👍💪

This is gold! You deserve more subs!

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.

Oh my lord, what a great job you've done !

Awesome video! Looking forward to see your complete test results. After this, you need to design the ultimate hotend!

Im new in 3d print and in 5 mn you provided me all the vocabulary I couldn't understand elsewhere. Hotend hotsink, ect, thank you !

Great job)) looking forward to next parts

Love you! Love your work! Pls continue :)

Good lord this video is the sacred graal of extruder videos and has only 40k views. Gj, that’s awesome!!

The video we've all been waiting for!

Top Gear reference is all I needed to trust this. Thank you!

Now this is nerdgasm x10 🤤🤤🤤 Awsome video!!!

excellent video! looking forward to the rest

You're doing gods work here !

Amazing video! Videos like these are my favourites.

it's mind blowing! Great job!

We need more of these episodes!

Excellent content! Would be nice to include the humble cr10 too, with so many Enders out there it would help many people know exactly how much performance they'll gain for each of those upgrades
