Can you make pulse jet engine? (Valved version)
Pin this before it gets lost😂
I have been requesting the same video for years. Tesla turbine vacuum pump. NOBODY has measurements of the ultimate vacuum you can reach with them and it is one of the main use cases listed in the patent. PLEASE do this. If you can reach 1x10-6 it would advance the DIY semiconductor hobby by leaps and bounds.
@integza. Put a water cooling system on the tiny pulses get so that you can get the most trust out of it.let me know how it goes..or LIQUID NITROGEN COOLING RUN IT TIL THE WHEELS FALL OFF
Can we all take a minute to appreciate how well made that spot welder looks, despite the obvious home made nature of it.
Maybe future video show how it's made!
Edit: Do i have the most upvotes?
P.S. I love tomatoes
Nothing like some fine microwave repurposing.
It is cool but inexpensive, mini cordless spot welders, that are highly capable, are available over the internet, so I’m not sure why anyone would bother building their own, unless they maybe needed something highly specialized.
I think he made it 1 or 2 videos ago
I'm convinced that he will end up learning how to weld and 3d print and physics and get a PhD and whatnot - before he builds a working engine with homemade stuff
@@Yadobler I just wanna see him use a rocket to actually push/lift something
I think a video about you learning to weld better, so that your jet engines can fully shine inhouse would be awesome! The process of your learning and tips you pick up along the way would be amazing to see!
Even if he learned a very specific type of welding and for a specific material and just used that type of metal etc. That would be really easy on him then. All the speeds, feeds, amps, and instructions are already out there on the interwebs.
more like this video is about how to not weld better
@@TrashcanScienceStuff you have added something, yet taken away more. Typical mohamed mindlessness. I’ve seen pigs on a farm smarter than anyone I’ve ever met with that in their name.
plenty of learn to weld videos online
I don't think the world needs another upload on someone learning welding
11:01 is his learning curve.
I’m so envious at people who understand how the math side of these things work, I’m studying electro mechanical engineering next year and I’m bricking it for the algebra side of things. No matter the questions I ask chatgpt or the UA-cam videos I watch, or the book I read, it just doesn’t sink in. It’s like I’m trying to speak Japanese without knowing how to.
you must see 3blue1brown series on basic algebra and calculus, is a masterpiece it should be mandatory in engineering classes
Keep at it. It's normal to be frustrated initially when trying to learn something new. Little by little things will fall into place, especially if you keep at it. Find a handful of approachable concepts, master these, and then slowly add new ones. If you dive in and expect to absorb everything at once, you will be lost. If you stick with it, you will get there.
Unfortunately that’s the teaching method at the uni I’m going to. Every day we learn a new piece of math equation. I had to postpone last year because it was all getting too much and I also had some health concerns but I kept on with it throughout. I understand some and others are like aaaaaaaagh. Derivatives and integrals are my main frustration but I’m hopefully going to get an appointment with the uni soon before I return in September to discuss some options.
@@daveysmith3944 One method that worked for me, is to print out on A4 sheets of paper, then post them up in your room using Blu Tack to avoid damaging the surface of the walls. On each sheet of paper print a set of derivatives and their solutions on one line for each derivative, and each sheet of paper should contain a set of related derivatives. Do the same with different sheets of A4 paper, with integrals and their solution;. For derivatives and integrals try to fit each one on a single line.
This way your brain will subconsciously register them when you spend time in your room, and when you wake up each morning. Fitting each derivative and integral on a single line where feasible, helps the brain to better focus on each one.
Buy a pocket sized notebook and hand write the same information on each page, as the A4 sheets, so when you're out and about, if you're waiting in traffic, or a bus or train and are bored, open the book at a random page and glance at one page then the other in a relaxed frame of mind, don't try to read and think about the derivatives and integrals. When looking at the A4 sheets in your room, don't try to read and think about the derivatives and integrals, just glance at them in a relaxed frame of mind also.
In addition to derivatives and integrals, also print out A4 sheets and hand write in the pocket book, trigonometric and logarithmic mathematical relations. You may prefer to hand write on one page of the pocket book a set of derivatives and the facing page relevant trigonometric or logarithmic equations.
If it helps, write the equations in terms of Electrical/Electronic/Mechanical parameters.
To improve memory and brain function, another tactic that helped me was to take natural Lecithin supplements tablets:
www.ncbi.nlm.nih.gov/pmc/articles/PMC4882550/
When I attended University, there wasn't easily accessible information available about taking wild fish oil supplements; had I known I would've also taken them at the time. Although I did start taking them after I graduated from University with my Electrical/Electronics Engineering degree:
"... Ingestion of omega-3 fatty acids increases learning, memory, cognitive well-being, and blood flow in the brain. Omega-3 treatments are advantageous, well-tolerated, and risk-free ...":

Your dedication to your art of engineering goes above and beyond. When you want something, you learn about it and then learn how to do it.
I know engineers who are not happy to teach beyond their grasp.
Great work my friend!
Your spot welding technique is actually used in some pretty advanced aerospace applications. The centaur upper stage rocket is a "balloon" of ultra-thin stainless steel sheet metal (around 0.020") that's joined and sealed with tens of thousands of spot welds. It's so thin that it has to be pressurized or it'll collapse under its own weight, but it's the highest performing upper stage rocket in terms of mass fraction
Integza: Tomatoes are disgusting.
Also Integza: This Moroccan style tomato-based sauce is pretty good.
@@FLPhotoCatcher only because its the blood of his enemies
Hey it's the cryocooler guy
Tell. Me. More. That. Was. Cool.
You should make an Integza Nerf Gun. Powered by rockets or something and probably illegal in many parts of the world.
If you're aiming to launch normal darts (standard .50 cal) then there is nothing that hasn't been done i think the highest muzzle velocity is 400+fps for a "regular blaster" and backyard scientist and ididathing have broken the sound barrier with a dart.
So, 3d printed gun.
Its an full auto nerf gun using the exhaust of a pulsejet to propel its darts
@@barnabasrsnags4828 probably wouldn't beat Gatlingtommy's moab
This comment is a scam, anyways you'll probably get the 3D printer from integza
Hi Integza, love the material and ideas. Keep them coming! Apologies if you’ve done this already but I would love to see a practical demonstration of a rocket motor idea I was once told about. Essentially, it’s an integral hybrid fuel motor. The solid fuel component is a hydrocarbon. Typically heavy oil mixed with an epoxy resin. During preparation, this mixture is held in a cylinder, turning on a centrifugal turntable, turning at a modest but, appreciable r.p.m. The oxidiser component can be liquid oxygen or nitrous oxide and is injected from the bottom into to the liquid phase as it spins in its mould. The oxidiser often helps to activate the epoxy. Another initiator may also help. The end result is a honeycomb of oxidiser bubbles within a solid fuel matrix. The purpose of the spin is to form a density gradient of bubbles with more at the centre and fewer at the outside. This is supposed to aid initiation, and also to permit thinner walls in the reaction chamber is the solid fuel mass remains a structural component until the end of the burn them, I reducing rocket mass. I’ve only ever heard this talk of and have never seen it done. The strikes me as an excellent practical experiment for your channel.
I have been wanting to get into 3d printing for a while, this channel has inspired a new hobby lol
I think you should try a peroxide rocket thruster! The thrust can be quite amazing!
Edit. I mean using itself as thrust by decomposing with catalyst.
You can get very high pressure whith it!
Edit2. It is a different mechanism!
Yep
Did u win
He already has
Wow so many likes thank you guys!
He already did
Great Video! My suggestion is to build a testing rig for all your engines and see which one has the best thrust to weight ratio! Could be like a tournament between the types of engines.
He already built one, he used linear rails from a 3d printer to do so.
That's impossible when your jet engines last .5 seconds before melting.
@@HideYaWife69eh, even a half second burn is enough to get TWR
haha true@@HideYaWife69
I don't wear gloves either, LOL! Thank you. You inspire and educate this 32-year-old Music-Man tremendously. I wish I had come across your page waaaayyy sooner. Only advice I can give to you. 💯❤ DO NOT EVER STOP DOING WHAT YOU DO, BECAUSE WE NEED MORE PEOPLE LIKE YOU, SO THANK YOU!!!🏁
Integza, you should be given a medal or acknowledgement from NASA for single handedly inspiring a generation of Rocket Scientists to go out and change the world!
Video idea: I would love to see that pulse jet in flight! I don't know anything about 3d printing... but I think making a plane for the jet would be amazing to see!!
THAT WOULD BE AWESOME
@@evy_leevy I would love to see thrust readings and all...but I would much rather see them actually flying! That would be so outstanding, imho!
Hey Integza, talk to RC Test Flight!
would you be able to do a homemade telescope?
I'm not sure if the lenses or mirrors can be homemade and work well enough
The important question is what's your budget... If you just wanna see the moon and planets .. even saturns rings , you can make one for pretty cheap , I made one for about 25 usd
@@zakirsheikh4209any link for that?
That would be pretty impossible without expensive technology

The vibrating water tube looks like an awesome engine idea. Simpler than a stirling. Just apply tidal engine to it. A floating magnet and a coil and it's done.
Wish I had a science teacher back in my day that held my attention the way you do🤔. Great job brother
You should make a hall effect thruster by using a magnetic field to limit the electrons' axial motion and then use them to ionize propellant, efficiently accelerate the ions to produce thrust, and neutralize the ions in the plume.
But hall thrusters only work in vacccum not in earths atmosphere
The atmospheric version of that is the ion thruster.
@@brktegebrehiwat5699 The atmosphere does not prevent them from working it just makes the thing they are pushing slow down too much
He could do it in a vacuum chamber…
I think it would be interesting to make some sort of engine powered directly by the output gases from water electrolysis. There are a lot of videos on how to do electrolysis but not much on what to do with it.
electrolysis consumes the materials used, uses a lot of power to generate relatively little amount of gas, and the mixture is more an explosive than a fuel; so I ask what's the "interesting" part of carrying water, batteries, to produce so little thrust with a happy explosiveness twist to it? It'd just be a gas-fired engine, HO or HHO gas, it's not "electrolysis powered", like why.
If you put a very fine screen vertically between your electrodes and make sure they always stay submerged, the gas bubbles won't flow thru it as they rise vertically. Then you have pure H2 and O2. This is much more useful as you can recombine them in a controlled manner, instead of a difficult to handle explosive mixture.
Also the ideal voltage is about 1.5V for maximum efficiency. It shifts a bit based on pressure and temperature, but that is more complex than most hobbies are going to take into account. Using a higher voltage produces more gas, but heats up the water. So it is less efficient. The electrodes need to be as close together as you can make them while still having a separation screen. To lower the resistance and increase the current, which results in higher gas output. Also adding KOH to the water lowers the resistance dramatically and increases output.
@@dimitar4y No need to small brain everything in your life.
The output gases don't need to go into an engine. It could just be a novel way to get the gases relatively safely. Like for example a mobile balloon filling machine that you charge at home, take to park and fill baggies or balloons with the hydrogen and cool. To make it more entertaining, could make them blow up in the air after a small delay. Now that's a new years special episode.
@dimitar4y For the fun of it. Why not? I never said it's useful. I personally know how inefficient it is. Why do people try to prove they "know more" than someone else in this ridiculous of a context. I find it interesting because I do. Why does there have to be a reason for finding a challenge interesting?
Where do you think he got all that hydrogen?
Man, I was literally just watching the latest video from Stuff Made Here, and he bought a super powerful and cool water jet cutter. It would be really awesome if you could do a collaboration! Love both of you guys, you both really inspire me in my engineering career 💪
That little pulse engine is brilliant! I’d love to see it fitted to a tether car and see how it goes compared to the little nitro two stroke engines.
I think you should build a test stand !
It would allow you to actually put numbers on your engines. And depending on what you measure it could help you troubleshoot the engines.
Interesting videos, keep it up !
I am a sheet metal worker and have used spot welders millions of times but never seen one made from pliers... my man ur a genius! with that said I have always been interested in attempting to build a model sized hybrid solid rocket engine / jet engine. I think this would be an awesome project for you to take on.
this vid has given me many ideas about using my sheetmetal expierence to build a rocket🚀
I would like you to reattempt the first jet engine you ever tried to create with all the knowledge you have learned over the years
Amazing. The part with the fireplace silicon and carbon mesh was very clever, even if it wasn't the final solution.
You should try using electrolysis to make a hydrogen thruster! Love your content.
good idea
yea
Imagine the potential of combining two powerful techniques: electroplating and 3D printing. By utilizing electroplating, But let's not stop there. Have you ever considered the synergy of two different engine types working together? Envision a Rotary (Wankel) Engine serving as the powerhouse to drive a pulse engine. Such a combination could unlock unprecedented efficiencies and capacities in the realm of engineering and innovation. Let's explore the possibilities!
Make a multi-stage rocket solid or liquid fuel, for the solid rockets adding aluminium powder to the resin should make if more efficient such as in solid rocket fuel
I like this idea
you were my inspiration to sturt studying mechanical engeneering
Congrats on 1 mil! ❤
The pulse jet needs a lot more fuel, try turning the propane tank upside down to inject the liquid propane instead. Another thing you can do is to look into Lockwood pulse jet designs, they are said to be easier to start and also simpler in design.
You should try to design a 3d printed shaped explosive charge.
A rocket is a controlled explosion, but so is a shaped charge. Would be awesome to see if it would be possible blow a hole through like 2 inches (5cm) of solid metal using 3d printing
he doesn't have explisive so I don't think it would be possible.
That is probably illegal😂
@@Pman353 Probably not, here in Sweden it’s illegal to even ignite a model rocket or a firework with more than 100 g of propellant. I don’t know what the laws are in other parts of the world, but obviously not as strict as in Sweden
@@hampusmollgard4954 it’s illegal in the US so I’m gonna assume it’s illegal in Portugal as well
That's illegal in the most of EU
this is also one of the things that causes the guns to have such a loud sound it's not the bullet breaking the sound barrier it's actually the hot gases hitting the amblant temperature that causes that loud cracking banging noise
This video popped up on its own, but I liked it so much I had to watch it through! Very cool my friend!
A huge improvement to the 3d printed plastic version would be to fill the "walls" with water! Just imagine putting a bigger cylinder over it and filling the gap with water.
Did you ever throw a water filled PET water bottle into fire? It doesnt melt, because the water cools the plastic better than the fire heats it. Same should work here too! I dare you to try it in a future video!
Until the water evaporates.
And explodes and throws super heated water and steam everywhere
Haha very very bad idea, as stated below there are 2 options
1. You make a vent and it eveporates
2. You don't make a vent and it explodes
In both cases the water won't do much if anything, because it is spread thinner than in a bottle, and will heat up faster.
A PET bottle will usually melt before it explodes, and the fire will make microscopic holes that relieve preassure.
add 2 ports intake and outlet and water cool it with a pump and radiator
@@kubik7203 that would make it way to heavy and complicated
10:02 imedeatly thought about an aztec death whistle when i heard this
An idea for a video: Build a 3D printed sterling Engine and try to extract the most power possible from it
I love your enthusiasm. Just a small correction, the V1 rocket of WW2 was propelled by steam from a chemical reaction.
You should try out a arcjet engine! I haven't seen a proper one on youtube and it woud be awesome!!!
A suggestion for a future video: My pc fan recently broke down so I bought a new one, more powerful but also stupid loud. Since you're pretty good at building ionic thrusters, try building an ionic pc fan. I know it won't fit in the case, but at least it should be able to plug in the motherboard. I know you can do it!
That would be cool even if it isn't powered by the motherboard
Have you ever tried to do the same but using a sterline engine concept? You could try to use various modern day nethods and liquids to keep it running to cycle
You are awesome, man! Keep doing the great stuff!

Please build the " THUNDERSTORM GENERATOR " for internal combustion engines using water as anatomic fuel invented by Malcolm Bendall
Are you TRYING to get him assassinated by the C.I.A?
Build a ram jet or turbo jet engine and compare the amount of thrust to the pulse jet engine..
I like the pulse jets, but I think one with some kind of cooling and/or throttling (to control both temperature and thrust) would be the next logical step.
EFI is making this relatively easy now days.
Dude, you rock! I took a welding class a few years ago and I’m super impressed by your home brew spot welder. If it helps weldingtipsandtricks is super helpful.
You should make an MHD thruster
hi Integza, quick welding tip when you weld you want to heat up the area where you want the join to be. try putting the blowtorch a bit closer and then apply the material you can also then reheat the surface. This avoids potentially harmful dripping and discolouration of the metal. But so far you're doing great soo keep it up!
that mini spot welder ❤❤❤ love it mate 👌
Somewhere in the fields of thermodynamics, frequency modulation, and high energy sources lies the fundamentals to space travel. I've felt this in my bones since I was young. Something to do with the controlled resonance of metallic/ceramic materials and the resulting vibration interacting with the surrounding medium is fascinating to me.
Anyone else think it’d be a cool idea for Integza to put one of his engines in an RC plane or rocket? I’d pay good money to see him play Kerbal Space Program IRL.
When it’s does in a lab it’s called science but when it’s done in a garage it’s called a felony

Stumbled across this and then subscribed. Finally the algorithm paid off.
Measuring the thrust on a bunch of your old engines would be cool to see.
Try optimizing the jam jar pulse jet engine (using something else than the jar), to get the longest run time and put it on a small boat or car and see how far it goes
Is it just me, that it actually sounded like an aztec whistle. Anyway it was a cool project Integza, i hope yo see more about jet engines.

6:50 Who else is just sitting here & waiting for the stuff at the wall to start melting?.... :/
Really smart to start a "flame thrower" inside.
Oh nice I love this effect. It can also work in reverse allowing you to use a specific sized tube and its matching frequency of sound to create a heat pump. I'd love to see you try that out btw.
Here's an idea for ya! I think 3D-Printing a pulse jet rocket and mounting it on a flywheel/Alternator assembly might just grab the attention of StyroPyro, AND ElectroBOOM both! I think a colab with all three of yall would be amazing.
Bro you’re smart you can be good at anything you put time and effort to including welding
Video idea: use one of your rocket engines and put it in an actual rocket, but with a tomato underneath the rocket as it launches.
That spot welding is amazing I bet you could make a turbojet with that. Also you could use brass pipes to make a radiator
A fun theme would be taking this really awesome engineering and fabrication for a super complicated Rube Goldberg to make like tea
I made a waste oil heater for my garage that functions like a pulse jet. It resonates at 48hz, so it's a little more like the hum of a subwoofer. It's gotten me through a few winters so far and can run steadily on as little as 24 ounces per hour.
Could you link a video which you used as a template?
@@Boz1211111 it's an original. If you're on Facebook, I shared a couple of videos in a group called Waste Oil Burners. That's the only place I've made it public though.
I think you should try liquid cooling for your engines. It sure takes a longer time to make, but the benefits could extend burn time to multiple minutes if not more. Maybe "weld" a long metal tube in a spiral pattern around the burn chamber, attach a pump and a coolant reservoir, make the pump move the liquid through the pipes into either a large coolant reservoir that would act as a heat bank or a radiator from a moped or pc or something. It sure would make an interesting video. You could also try adding some heatsinks to your engines to radiate just enough heat to stop the engine from melting. Remember to use thermal adhesive, thermal pads or thermal paste between any cooling element and the surface.
That's kind of what's happening with that coil of fuel line around the combustion chamber, but I agree, a dedicated water line would help get some life out of these little engines.
Just put a tube over the tube that makes up the engine and pump water through the gap between them, much simpler to produce and just requires a couple of large washer like plates to seal it each end and a small in and out hole for circulating coolant
why not having that modeled in the file and printed in metal, pipes around the engine for liquid nitrogen, i think a rocket engine is far more efficient at heat dissipation since the combustion occurs outside the engine body.
Love the music you use in your videos
Congratulations integza, you got one million subscribers
You should strap that jet engine to an RC plane! I'm working on one myself (electric). That homemade spot welder looks awesome! I would really like to make one myself. I also like how he says every time, “Remember, tomatoes are disgusting!”
I love your videos! I can't wait for the next one!
I’ve been trying to get into 3D printing for a while yet can’t bc of price and your videos are really amazing to show what it can do. Also an idea for a next video could be trying to practically/semi-practically apply a jet you’ve made for something like a model plane or rocket
Great! There's a fascination to making big stuff tiny and working like the big ones! Would have loved to see the thrust it produces.
Congrats on 1 million subs!
I have 2 ideas that you could try:
1st. Use BrownGas(HHO), it will be more powerful because it's already mixed with oxygen and it's has a quicker ignition time and fire propagation times. Instead of pure hydrogen, BrownGas is easier to make(12V 7A electrolysis) and more safer, because you can control the production debit by a potentiometer =))
2nd.Also, to be sure that the jet engine has a proper cooling, why don't you make some fins on the body of the engine? You can use a simple fan or some water that is flowing over the body, in that way, you will solve the problem with "thermal isolation". The fins can be some metal strips welded on the body, you don't have to make it look fancy =))))
But isn’t there a risk that the engine might explode when he decides to ignite it, since there is already HHO in there?
It's a good idea, the browngas is too ez to made,lol
@@xmysef4920 nope, I test a thing like this( I made a torch for melting and welding), and I have 2 control systems: the power from the PSU and the gas valve + if it's backfire the HHO, it will burn just what you produce, not an entire tank full of gas at 4 PSI =))))
Good ides, i up this
daddy uwu
Hey Joel! You should make an Electrostatic Piston Engine. Allow me to explain.
Basically, if you have two metal plates charged at the same polarity, they will repel. If they have different and opposite polarities, they will attract.
What if you made the Piston of your engine negatively charged, and there were plates on the bottom and top of the whole cylinder which would switch polarity? You could repel and attract the piston in a reciprocating motion, thus causing a crank to move, and rotary motion.
Theme for a future video: build a microwave electrothermal thruster (MET). Basically, use the magnetron from a microwave oven to heat water vapor within a resonant cavity into a plasma, then accelerate the plasma using an electric field and eject it through a nozzle. This is one of the newer technologies being used for space tugs.
a rollbar for a truck that has a logo lit up from the back by a solor powered motion sensor light sold at local hardware store. Love the video. And would like to get into 3D printing. I am a general contractor who is always learning.
I would have liked to see how well a ceramic printed pulse jet engine performed.
Possible future video/implementation
you could build a small thrust measuring setup, guided on air pressured rails (atmospheric railway), so the future jet engines can move with minimal traction. More air pressure could also support the weight of the whole system. The thrust could be measured by the sled pushing against an precision scale. This way you could directly record it for the your videos
It would be really interesting to see and compare the thrust from different engines
Congratz on 1 million subscribers!
3D print a Nixi tube clock housing that allows for the tubes but also a Tesla coil on either end so you get a cool electric field above the tubes. Always wanted to build one.
You should get a larger version of it and fit it on a small 3d printed plane the the v1 missile and try the new one using hydrogen to see if it’s better
Imagine what could be done when integza gets a metal 3d printer! 💪🤘😤
I just saw your Chanel hit 1m. It went from 999k to 1m. Congrats
you are the best the best inventer i ever seen!
I would love to see a return to some old projects now that you can get certain metal parts 3D printed. Just being able to see what potential some of your old designs would have I think would be awesome.
you should make somthing with a 3D printed roman steam engine (Aeolipile). i belive that this will be interesting to try getting the engine working without it meltin gbut also being light weight enough to spin at high speeds.
A video on the rotating detonation engine, the most powerful type of rocket, with comparison to a normal one and a jet engine in flight will be your best video
Love your videos
Dude I don't have any suggestions on what you should build so I suggest you pick something and I'm sure I'll be equally as amazed as I was with the pulse jet engine. Good stuff bro!
Its been so cool watching you over the years making more and more complex rockets and other cool stuff! I would love to see if you could make some sort of RC car or boat with your engines. Keep up making awesome videos!
RC AIRPLANE!
As always great video! Love seeing your takes on these integral engine designs. Perhaps you could try and combine the designs of your best engines to make a super engine? Kind of like the SR-71 turbo-ramjet.
Actual rocket combustion chambers have air/oxy entry ports all around the outside of fuel/oxy entry area. It keeps the outer shell cooler w a buffer of cooler oxy while fuel burns mostly inbetween the center fuel stream and oxy layer where it mixes.
Fun Fact: the V-1's pulse jet created a steady 45Hz drone (smack dab between an F1 note and F#1 note on a midi keyboard for reference) that earned it the name "Buzz Bomb" by the british
And. . . Doodle bug.
Video idea: you should make a magnetohydrodynamic thruster powered boat. Or just try to make a well optimized MHD thruster that could be eventually used to power something.
It seems like very few have attemped to make something like this on youtube and i would love to see you put your own spin on it.
(Yes I liked my own comment)
Magnetohydrodynamic drives suck... you need passive amounts of power
Integza has now started making serious and very informative videos. This is so satisfying! I hope it continues like this!
Put the truster on a helium balloon, also again a very good video keep it up!
for your next attempt at it, you could try to pre-cool the fuel before sending it into the line (the way you have it wrapped around it like that) to help the material not overheat. My concern would be the fuel line itself could fail and cause a dangerous situation while giving an added advantage of keeping the 3d printed metal from possibly failing as well. since it requires a temp difference though you may have to split the line before it wraps around it so that way you could wrap both sides before rejoining it at the injection point. this way you can cool both sides while still getting the temp difference.
