This is exactly the kind of ridiculous, non sensicle, unreasonable over engineering that inspires so many people to innovate and make awesome things. Please keep doing this!

[@probablywrongagain2151]

I love this project!! Looking so forward to the day of an actual run.

[@MatrixRay19]

About the temperature control loop: Danger Klipper has MPC as an option other than PID, which works just like how you described.

[@Mouhfighter]

ok, lets face it, we have reached a pooint where ii have to write it, please load RGB colors and create a code that does mix different amounts for different colors....

[@markfen88]

and no benchys. ive been bamboozled.

[@fravier10001]

I thought the same, but the title says that "he could print" not that he printed it.

[@blackpete]

Bambu-zeld? 😂

[@kingkasma4660]

Its perfect to make an art deco style 3D Printer! :D

[@eclsnowman]

So happy to see Martin and the guys at Bontech hooking you up with the best extruders out there. I have known Martin for many years. He's always done a lot to help people in more demanding applications. And as you said... if yours isn't a demanding application, whose is 🙂

[@BRUXXUS]

Spectacular work! Seeing melted filament blasting out like a firehose is wild!

[@DanM2509]

Brahma is a god with four heads, believed to have originated from the four Vedas. The name for the hot end

[@bunkie2100]

Just before you said “I’m not a native speaker”, I was thinking about how well you were explaining your reasons for the differences in finishes along the path of the filament!

[@scythelord]

I see a LOT of moisture in that filament. All the bubbling out the hotend, especially around 1:09:40

[@VicknairDoesThings]

46:56 “…this is pretty much a complete unit.” One may even say it’s an Absolute Unit 😂😂😂

[@BRUXXUS]

I love this idea for the name!

[@evren.builds]

This exceeded my expectations! I love how you're making the impossible possible step by step I was also thinking it would be amazing to be able to lap the channels via *abrasive* *flow* *machining* Can be done with a hydraulic press. looking forwards to the print!

[@polarbear2272]

Crazy idea for a crazy project: have you considered direct heating the block by shorting say 200a through the block at low voltage? Might be possible to control heating location by mapping resistance and should be very responsive.

[@BTom16]

That is absolutely wild. Impressive work. Congratulations. ❤

[@keinschwein8467]

You should definitely keep the name for the second heating stage sub assembly "Just the tip" (and the cooling assembly "Only from behind"). (But we shouldn't get ahead of ourselves before we draw any cockclusions. SCNR)

[@wreckexplorer]

Hello Jan, love your content 👍🏻 A little "off topic" but is it possible to do a test mixing the filament with this model and create different colors (RGB) while printing? Very curious about this.... And could be a gamechanger...🤓🍻

[@Roetz40]

I don't plan on going RGB or anything but we will definitely get some color going on in the next prints. ;)

[@jaykop2611]

Theoretisch könnte sich das Fielament beim Polierten Port den leichtesten Weg ja aussuchen. Die harte Seele muss bei der groben Oberfläche aber an der gerade so plastifizierten Randschicht gleiten was am Ende ja mehr Reibung bedeuten würde. Stick Slip gibt es ja eher bei festen Gleitflächen. Bei Zähflüssigen Flüssigkeiten spielt eher Wandreibung eine Rolle in der die Flüssigkeit am Rand fast "steht" und zur Leitungsmitte dann an Geschwindigkeit zunimmt. Damit wäre eine schnelle Plastifizierung Key...aber das ist mit diesem Juwel kein Problem bzw kaum zu verbessern... Respekt für die Konstruktion und Fertigung! Am Ende denke ich macht es aber warscheinlich keinen merkbaren Unterschied ob Poliert oder Sandgestrahlt.

[@blackpete]

Ich würde tippen, dass die rauhe Oberfläche turbulenten Fluss ermöglicht. Das würde eine bessere Durchmischung des Filaments und schnellere Erhitzung begünstigen. Fluiddynamik ist jetzt nicht mein Gebiet, kann daher auch falsch liegen.

[@paul_devo]

Well done, no leaks!!’ Don’t group the ptfe tubes together that the top, you’re adding resistance

[@Hiltomatt]

10g extrusion in 60seconds. Fast and the Furious popped into mind. Going to need some overnight parts from Japan.😂

[@blackpete]

Nope. In 30 secs. That's more like topgun on speed.

[@TheFutureIsEloi]

Ah, The Bulldog. Now I understand...

[@chovavmordechai]

Great video! It felt like 30 minutes. Can't fault a single thing. Waiting for the next video! Keep them long.

[@GuediRawstyle]

Ich möchte hier mal deine Lesezeichenleiste erwähnen. Nicht das ich neugierig wäre aber als mir 3D Pimmel aufgefallen ist musste ich erstmal lachen 😂. Trotz allem hat mich alles umgehauen wie viel arbeit du in allem gesteckt hast und was dabei heraus kam. Klasse Video 💪🏻

[@erickong9]

Possible to feed RGBW or RGBK filaments with different flow rate to mix out all colors?

[@BRUXXUS]

I don't see why not! I would be interested in just seeing what it would look like with 4 colors all at once! :)

[@controlflow89]

This hotend looks TOTALLY EPIC!!!

[@qanoz8020]

I love this project so much, is is so innovative compared to the usual route to getting a fast benchy. I am now building my second custom printer to print fast thanks to you

[@JohnHansknecht]

Nozzles should be designed with a bevel on the end to match a bevel on the hot end, similar to a swagelok fitting that can handle 20,000+ psi without leaking.

[@SarahKchannel]

31:40 thought question about the surface finish - cant wait to see the results. One hand hand, having a rough surface increases surface area, yet maybe less contact area for un-molten filament. On the other hand I see nothing wrong with your approach and argument either.

[@ScienceMessiah]

Nice project. However, it's not about pushing force, what's important is that you get the plastic to temperature quickly. The steppers skipping steps is because it's trying to push unmelted plastic. You can see it's getting too cold when the extruded plastic expands and looks like sausage. But I like your attitude. Just trying stuff no one else tried before. Way to go. Viele Grüße

[@CarloVaccariPlus]

I think if you just tapered the 2mm holes into 1mm wide slots before joining you could dramatically improve the heat transfer without ever running into what I call the "cht wall" where the unmelted filament reaches the splitter.

[@Roetz40]

Yes, that's an interesting thought. But that comes also with a very drastic and sudden change in melt velocity. (Twice actually). I have no idea how much trouble this is going to cause...

[@CarloVaccariPlus]

​@@Roetz40 Everything is so laminar regardless of surface finish that there's no issue with speed fluctuations in the melt pool. Also, if you *are* concerned with that, simply make the narrower slots deeper to maintain cross-sectional area.

[@CarloVaccariPlus]

This slot design is used in the Nanoflow tungsten carbide nozzle.

[@fravier10001]

It is an absolute monstrosity, I love it.

[@iFilipis]

This extruder looks straight out of injection molding machine. I wonder what kind of pressure it can make

[@coorexz]

All I could think of at the 41:05-mark is, that's an LGX Hydra taking form.

[@methlonstorm2027]

what i dont get with direct extruders is why use contact wheels when you could get a better grip over a longer area using a track/belt system to grip the filament from both sides would give huge friction without damaging the filament any way super impressive work. i think you have a solid theory on surface melt look forward to see the results. thanks

[@jamieclarke321]

10/10 if it looks good it performs good

[@AwesomeSaussage]

I would say even 20/20!

[@blackpete]

Looks and performs... GOOD? 😂😂😂

[@mihalydozsa2254]

You can use it for injection molding too :D

[@BRUXXUS]

That's what I was thinking. 🤣

[@nathangek]

Would you be able to do CMYK color mixing with this if you had some sort of "rifling" in the final combined path?

[@blackpete]

Regarding the heat drop problem, would it be possible to have multiple sensors at multiple locations, averaging them or using the lowest, median or what works best?

[@Markusfried78]

Love it!! Will die swell not be a Problem to get a precise benchy shape?

[@Roetz40]

We'll see. If it's becoming a problem we have to find a sweet spot between back pressure and a longer nozzle zone. ;)

[@Markusfried78]

@ looking forward to it! :)

[@Nevir202]

42:15 looks like some crazy motorcycle W engine configuration lol

[@KnowArt]

awesome stuff

[@heyrpe]

Have you looked into more detailed heater control in klipper? It looks like you have a couple of heaters in the big block, that you just control as one in the context of a bed heater. Klipper should be able to control a bunch of separate heaters, you could set them up all separately. You would need to drill a separate hole for each heater and install a thermocouple. In clipper you could then set them up as extruders oder other types of heaters. In the slicer you would just add a couple of commands to set them to the correct temperature.

[@kingkasma4660]

You can maybe use leather for the copper polish

[@Laborchet]

Let’s gooo!!! 75 min of content hell yeah!!

Subbed based on title lmaoo

[@methlonstorm2027]

oh and for a name its Frankenstruder cause that monster is built up from so many different parts :)

[@machinaexmente2729]

This is the stuff man.

[@henrivanderriet3895]

Is that fumes or steam coming off the extruded filament? Asking because the filament seems to expand at the high flow.

[@KD0AFK33]

I noticed the plate that said The Bulldog on it. Is that a plate from a bar?

[@docbrown172]

Immediately subscribed lol

[@paolopace10]

use klipper danger , has another option thats not pid and has filament density option

[@jimka385]

Need to tune those retraction settings! :P

[@iopfarmer]

Isolation on the big bloc?

[@platin2148]

Possible to Diamond coat the inner pipes?

[@ReNeyer]

Love the Bulldog tray to catch filament and the scale... Dont build anything with this, please...

[@max_bro34]

Servus Jan! Welche CAM Software benutzt du? Sieht aus wie etwas von Autodesk

[@iaa66]

Why don't you try ABS filament? It has a better thermal conductivity

[@hanswurstusbrachialus5213]

Sieht eher aus wie ein W4 Mopedmotor :D

[@stefanguiton]

Excellent

[@captianmorgan7627]

25:55 Tiny quibble. What you have is a hypothesis, not a theory.

[@apenaslink]

At this point a water jet, underwater or cooled air would prob be better for cooling.

[@xzzxz6368]

LGX + Slice = power! :)

[@thomaskletzl6493]

i would probably dosnt do anything for finishing because im lazy

It's not CHT. It's not CHT. IT'S NOT CHT. If you say it trice, Bondtech won't notice.

[@DiomedesDominguez]

5:30 be careful of using that splitting method, it's under a patent in US

[@Roetz40]

I'm not in the US and I don't intend on making any money out of this. I don't care for parents in that regard. But thanks for mentioning ;)

[@DerEbi84]

Würde ein größerer Filament Durchmesser (zB. 2,85) mit solch einem Setup mehr Flow verursachen?

[@rasmuskruger3179]

Amazing and excellent in every aspect. In my believe, the only setup to harvest the full ability of this hotend, is to have the the 4-headed beast actuated by a direct drive in order the supply the needed accuracy, acceleration and rigidity and at the same time have the workpliece steady and avoid quality lag. Good onya !!!! 💪💪💪💪

[@aliasjones3156]

This loocs really cool, but I can see one big hurble for you to overcome s soon as you really wont to go for a even remotely dimensionally akurat print. In your designe the diameter is really high just befor the nosel itself end has ohnly a vary short section of you 0.5mm diameter. This leads to a springback of the jst extruded material (this normally also happens with more normel printspeeds), In your case this seams to be pshed to the extream (like most other things of the designe). It locks to me that you would need a less steep transition from full diateter to final nozel.

[@thomaskletzl6493]

but isnt that a good thing if its consistent? you have basicly a bigger nozzle while beeing in the rulls

[@ziocrielo6148]

Hell yeah

Back pressure reducing maybe with a Tesla one way valve milled in?...

[@Gabs_Labs]

Nice idea, but seems too heavy! Maybe use some kind of bowden connecting to the multi extruder head.

[@Grayswandiir]

The extruder and hotend are stationary in this setup so it doesn't really matter how heavy it is.

[@Gabs_Labs]

@@Grayswandiir I will see all, ty for the explain!

[@The_Privateer]

Possible or not - why would you want to? Printing anything that fast (except for maybe a poop emoji) is going to result in hooooorible layer adhesion and dimensional accuracy. I guess, if you;re just printing bookshelf doo-dads, sure. Go for it. But if you actually want functional parts... speed is NOT your friend.

[@Roetz40]

We'll see ;)

[@woody442]

Speed = money

[@Jeralddoerr]

Overcomplicated... 10x more extrushin than needed.. unless you plan on 3D printing a house with that little extruder. You're going to have more problems in the future than you seem to have thought about.

[@Grayswandiir]

Why not leave a productive comment instead of just hating?

[@nikolaitoxvaerd]

It seems pretty simple? Instead of trying to extrude at crazy pressure and speed your splitting the workload in 4. Also the extruder and hot end is stationary so I can't see why it wouldn't be the best way to do it?

[@Grayswandiir]

​@@nikolaitoxvaerdI mean, it looks like he was provided the extruders for free, so why not use them? They are adjustable, so he can dial back the tension on the filament.

[@nikolaitoxvaerd]

@@Grayswandiir agreed as I said it seems like a really good way of having high flow rate
