I built a working Hotend out of a CPU cooler!

[@pedrohenriqueboscofi]

That's one of the most gamer hot end extruder setup ever

[@marsgizmo]

Dude, your projects are next level!! 🤘😎🤘 Can't wait to see what's coming.. 👀

[@properprinting]

Thanks Adrian!

[@MaxHackbarth]

The very idea that you can make that extruder with so many parts, make it look so easy and make it without any instructions too is absolutely insanely ridiculous dude!

[@DeadOwlProductions]

10/10 drilling a hole B roll. You got yourself a new subscriber.

[@larrythehedgehog]

Having an existential crisis when you realize the engineering challenge you set out for yourself was actually easy is a crazy problem to have lol.

[@oliverer3]

I've been there it's the weirdest feeling.

[@agapiosagapiou]

It's like cheating yourself

[@shogoonn]

The heat pipes are most likely filled with water (and sometimes with methanol). Definitely not ammonia, as it is used for lower temperatures and, most importantly, it's incompatible with copper, it will eat through the metal (I've tried that, but not with a heat pipe). What you bought is a solution of ammonia in water, which is of no use in a heat pipe (pure ammonia is required). You can put a piece of copper in that ammonia solution, it will turn a beautiful blue colour and the metal will dissolve after a couple of days. Both, pure and dissolved ammonia are corrosive towards copper. If you broke the heat pipe, you wouldn't be able to repair it easily. They contain a very small amount of liquid, and the remaining volume is filled with the liquid's vapour. There is no air inside, and that makes the repair process difficult. Due to the lack of air "ballast", the pressure inside a heat pipe at room temperature is close to vacuum (actually equal to the vapour pressure of the liquid). If you could keep one end of the tube at low enough temperature, you should be able to anneal the another part of the tube safely, provided that you will not damage anything else by the application of heat. However, keeping one end of a such short tube cool may prove difficult, first - due to the high thermal conductivity of copper, and second - due to the heat pipe action, as it will still work, albeit to a much lesser degree than in its intended operating conditions.

[@properprinting]

Thanks for the info! Shame that I never got to that point of finding that out by trial and error.

[@xJackHunter]

As if this is the only one you're gonna build lol@@properprinting

[@noanyobiseniss7462]

@shogoonn I need to repair my fridge in the Winnie that lost the containment, it is ammonia and hydrogen gas. Do you have any resources that can help me find a diy for this? It seems to be a state secret. :)

[@ИванЮрченко-ф2з]

Does it mean that the liquid in the tubes can be replaced with liquid with higher boiling temperature? And high stability and safety over 200C liquid? Like white spirit solvent or ethylene glycol

[@shogoonn]

@@ИванЮрченко-ф2з Water will do fine at 200°C, the heat pipe will run at a pressure higher than atmospheric. That's not a problem for small diameter tubes. I have some water filled heat pipes from Quick-Cool with working range from 5°C to 250°C. Otherwise, yes, you can have heat pipes with other liquids, including liquid metals. Filling a heat pipe is a complicated operation. It requires a filling station with a vacuum pump, liquid metering equipment, some valves and the ability to close to heat pipe after filling. First you have to pump out everything from the heat pipe, and heat it to a higher temperature to remove any residues adsorbed on the surface, and then you close the vacuum and open the metering vessel, (a small one) which transfers the precise amount of liquid to the tube, and then you close the tube (pinch and weld). There are other methods of filling, but this one is AFAIK the most common one at the factories. You could fill a heat pipe at home, which I've done successfully, by partially filling it with the working liquid, heating it until the liquid boils, and then pinching at the top, when enough liquid was removed (that's the difficult part - knowing how much is left), and then welding. The vapours of the boiling liquid will displace the air from the heat pipe. Instead, if you have a vacuum pump, you can add a slight excess of a liquid to the heat pipe and then vacuum it and seal it.

[@AmstradExin]

Not only looks the cut parts very good...the clockwork looks equally impressive!

[@properprinting]

Thanks!

[@kawaii5-0]

That whole assembly looks like it was designed by an extraterrestrial civilization 1000 years ahead of us, or an extremely capable Dutchman.

[@bspenguin2]

Very inspiring!

[@properprinting]

Thank you!

[@d-jm2xs]

Just FYI the amount of fluid in a heat pipe is tiny. Very little in there, and its usually under a low atmospheric pressure. It is almost always water as well.

[@properprinting]

Good to know! I was hoping to get that on camera that nothing was coming out, but it just worked xD

Add an active cooler using a fairly large wattage thermoelectric device with a cold finger to cool the incoming TPU to stiffen it prior to it entering your extruder. It's mandatory to add more RGB LEDs on the TEC hot side fan though 😉

[@ИванЮрченко-ф2з]

Brilliant idea again! Soon it'll become industrial. Adding heatpipes even spares some metall mass on hotend radiator because it cools much stronger on the place needed instead of cooling a 5-7cm radiator pipe. Besides getting the radiator out of the main heating zone gets it cooler and simplifies the setup.

[@ColinWithaT]

8:07 "This is a weird video." LMAO! Nice when something actually works. I hope you find a new challenge soon. Love the videos.

[@Vader294]

A few things. Heat pipes require a certain heat load to reach their max efficiency, You can also buy them online so you don’t have to worry about work hardening as much as a pre-bent pipe. Regardless, amazing work like always.

[@properprinting]

You're right and I want to design my own heat block and use individual heat pipes. The temperature range depends on the fluid that's being used. Methanol, ethanol or water is within the temperature range of this use case and I assumed that it must have been one of these fluids. No idea how efficient they are at which temperature though.

[@JanS-i8z]

@@properprinting i love it =D you might try some thermalpaste in the thread its messy but should improve thermal cunduction

[@SianaGearz]

Yeah I think I saw Conrad Elektronik here in Germany (active EU wide) sell individual unbent heat pipes not at all too expensively in any number of sizes, already 20 years ago. I had some thoughts and plans but never got around to make a custom heatsink.

[@mtmtrx]

​@@properprintingCould it work with peltier?

[@properprinting]

@@mtmtrx I haven't tested it, but from what I've heard this is too much hassle with almost no benefit. I was thinking about doing that, but ditched the plan.

[@spriteboost]

The extruder is a work of art :)

[@Ricciolo-oj1nc]

2:10 Heatpipes aren't easly refillable, they have like low pressure to lower the boliling point of the fluid inside, so you need to either fill it and seal it in a vacuum or with the tube really with the boiling liquid inside (and in the second case it will not perform good like the vacuum one)

[@SianaGearz]

This is true of water heatpipe where the boiling point is brought down to near room temperature by partial vacuum. This is also the fundamentally best fluid to be used in a heatpipe. But also you could conceivably give it some other fluid with an inherently low boiling point instead and seal it right with air. The ammonia solution sure seems usable with 38°C boiling point, if it also sticks to the walls and doesn't damage them.

[@SianaGearz]

Yeah no ammonia won't work, it reacts with copper. Methanol is not something you can seal easily, it will just explode on you. Acetone too. The last thing I can think of is diabolical but well. Dichlormethane. It might burn almost every polymer and your flesh to the bone and your gloves but it has a low boiling point and it won't catch fire, you can seal it safely in a heatpipe by soldering it shut. In Europe you can buy pure dichlormethane from Modulor Berlin, but since it's a restricted chemical you have to submit a written signed note detailing why you need it.

[@Mulakulu]

2:36 why didn't you use the other side of the calipers? The ones meant for finding inside diameters

[@properprinting]

Because this was easier to show on camera and was just to make the point. Not to do the actual measurement.

[@Mulakulu]

@@properprinting that makes sense 👌

[@squishy312]

I know that TPU loves to be printed way slower than you would think... That's all it could be. It doesn't melt as fast as other materials, so that's why the slowness is needed. It's not about the extruder not pushing it hard enough. It's about the hotend turning it into liquid fast enough. If you go hotter, it might burn. But you can do testing in both ways.

[@kevintieman3616]

"It's turning in the right direction, this is a weird video" 😂😂🤣

[@jacobmurray3621]

Wait I love it. Really good and cheap DIY heat sink. Revo hotends go for like $100+ and you made one for less then half that

[@properprinting]

And it's also not that hard to make one!

[@dfgaJK]

I love that you were dumfounded that the project went too well🤣 it seemed like you were on the verge of an existential crisis

[@Flumphinator]

Neat! Looks heavy!

[@zora_tech]

The only thing that is missing to make this the fastest 3D printer besides the RGB is to paint the whole thing red and add some racing stripes 🤣

[@eXitusR]

The failure of the flex attempt may be related to the upper filament path. Since the friction of the flex material is very low, it should not get stuck anywhere, so even the positioning of the filament above might be good improvement.

[@ziocrielo6148]

I think the skipping was because the tpu is too grippy and it's sticking somewhere above the extruder belts causing it to pull and stretch the filament then skip. It should help to reduce friction above the extruder belts

[@properprinting]

It was buckling and I think that this was due to the square hole. Once the filament starts buckling, and with 60A this will happen fast, you're done.

[@Hanzi2u]

i liked this video a lot ! thanks for sharing

[@olafschermann1592]

[@thegreatunknown8075]

what is in it is a miniscule amount of water in a near vacuum to aid in evaporation

[@eelcohoogendoorn8044]

That assembled acrylic sure looks sexy. One easy thing to tweak; those free hanging copper pipes look cool but unless that heat sink is bolted onto something they are going to result in some low-ass resonant frequencies ringing all over your part.
