Integza is competing with Electroboom to see who can put his skeleton into orbit first.

Tbh i would have liked to see more of the hydrogen with compressed air and experimenting with that cuz invisible fire making a red hot knife is COOL. cool video otherwise

I like the idea that you went, "not a fan of this plastic spinning next to me. I think ill stop." But you were just playing with hydrogen and oxygen in a shared line. As someone whose accidentaly caused a small explosion in that same way, that made me fucking nervous.

The duality of man's inclinations for technology: Can we make war with it? Or can we make food with it?

By using metal with holes, you're essentially making a... Swiss knife.

a bit disappointed to see you accepting a sponsorship from temu :(

A sword version of this with only half of the blade burning would be a terrifying weapon. Keeping the fire a half a meter or a foot and a half away would be a big improvement for the user too.

Alright, now that you've made a knife, we need a flaming sword

I've never feared for you life more than the moments i watched you hold a knife with a supersonic gas output with a flame front that was traveling back to the source.

I love when someone looks at one problem and realizes it's actually a solution to another problem they have.

Another material that looks just like the 3d printed porous knife, is the air mufflers/diffusers on industrial pneumatics. Under magnification, some of them look like brass beads that have been heated and pressed into a truncated (blunted) cone shape. If Integza wants an off-the-shelf porous material, that has pipe thread already attached, I would use the pneumatic muffler method. I just checked the industrial supplier McMaster-Carr here in the USA, and I see they even make stainless ones.

Mans just casually makes a lightsaber when testing a jet engine theory, Fucking sick.

The most incredible thing in this video is that he did all of these INDOOR. In a somewhat closed room.

A 3D-printed knife with a billion tiny hydrogen rocket nozzles in it is just too appropriate for this channel lol.

The repellant feature is awesome! Propeller and boat hull would make a low friction and perhaps efficient boat.

Next logical step is a Star Wars style light saber using plasma and magnetic fields to contain and shape the plasma.

As a guy who bakes bread, I love the idea that a bread company is trying to be as high tech as aerospace companies.

Please no more Temu😢

The video was awesome. I was a little worried about your ceiling in a couple of those shots though. Anyway I am an aircraft technician and totally agree with you. I can't wait to see how you incorporate it into a jet engine.

This concept has been in use in high-performance (military) jet engines for more than a decade. They don't use it for fuel injection, but rather air cooling the rear turbine blades. Turbojet power density increases with combustion chamber temperature, but past a certain point no existing materials can withstand the heat. The solution was to bypass some of the air from the compressor section through tiny holes in the rear turbine blades to cool them well below their melting points, minimizing turbine blade creep.

A TEMU-ad.... Would have preferred a Raid-Shadow-Legends app over TEMU

i don't know if anyone has suggested this, but try to create a rig for the knife you just made that spins the knife while it's rotating at around a 1000 rpm, and figure out the optimal rotational speed and gas injection pressure to create a literal flame wall... !!! props if you can do this with a long bar instead of a knife... this would be a good concept to start working on the jet engine tbh.... if the fan design can literally spew fire and rotate fast enough to suck in enough air, you have what you want.. :D if you like my idea, please conisider sending me that 3d printer... i would be absolutely thankful.... i don't even want it for free, i'm literally willing to pay what i can afford on my end to have one !!! living in a third world country is absolutely shit, can't find good deals anywhere and even if printers are available parts are missing that make it impossible for me to get it in my city in working condition...

I am honestly impressed you haven't burned down your house yet.

That hydrogen and oxygen experiment was a 50/50 chance of never seeing Integza’s neighborhood ever again.

4:30 nah bro, he enchanted his knife with fire aspect

Integza really be roleplaying as "THE GOD OF LONDON" in this video

You should make a "hot/ cold" house fan, make the blades out of your new porous metal 3D Print all the casing but have hydrogen source pumping into the fan blades so when it ignites you can have hot air or switch it off and have cold air. Major dangerous but watching you wave that knife around with fire all over the place. I'm guessing danger is your middle name. Keep up the good work. Have been watching you for years

Imagine a thief breaking into his house, seeing that flaming knife lighting up in the dark

Video idea: You should make a video collaboration with NileRed, where you turn tomatoes into rocket/jet fuel!

The fact that this entire video was shot INSIDE is insane.

"I'm a big fan of bread, but my true passion is jet engines." -Absolute poetry.

I can't believe we've looped back the internet to see integza do the 1000 degree hot knife videos

Disappointed that integza accepted temu sponsor

This is revolutionary. Now a jet engine can achieve trust and efficiency that couldn't even imagined. And they can operate in very high working temperature as well.

Bro this video is one of the more dangerous videos on yt.

You're thinking too small. You MAY be able to create not just a normal jet engine but a DETONATION engine. The trouble with detonation engines as I understand it is the combustion mixture comes into contact with a hot surface or hot gas and ignites before the detonation flamefront reaches it. This technology might be able to provide a forcefield of constantly incoming cold (and yet unmixed) gas that prevents this contact from happening. Just like bread dough sticking to a knife.

Not temu sponsoring the video 💀

I am excited to see what you come up with. As a 50 y/o retired Army officer I am blown away by the level of sci-fi that has become reality. There are even some technologies that I used in the military that have not become public yet but they have SO MANY possibilities. I love to see what happens when someone with a high IQ thinks outside the box and changes the world for everyone!!

You need a longer HANDLE made out of CERAMICS :) A sword variant is obviously the next step...

as an avid Temu enjoyer, here's a thought although challenging it would be : Make a rocket/jet/flying device with only products from temu. this would obviously not include ready made flying things like drones and the like.

That is so cool! I tried making a flaming sword once by casting aluminum over a tube that ran down the length of the tube, then drilling through the edges of the blade. It was a bad design.. for a lot of reasons haha. That works so much better and you can still use it like a knife!

I don't believe for one second that you actually use TEMU to get anything.

Dude that screeching is called flashback. U could end up an exploded smart guy who had a good idea but was not smart enough to install a flashback arrestor in the fuel line.

I am amazed your house didn’t burn down.

Cmon, even a RAID shadow legends sponsor is better than Temu

Okay so the coolest part to ME was that it "Self-Cools". Air is a super good Insulator, that's why Insulation is often just very very porous materials or Fiber's of something. So, when the knife is burning something without an oxidizer, it would probably never get hot enough to damage itself. BUT when you add a little more "Power" with the oxidizer, it get's Red-Hot and the SECOND the oxidizer is gone, it self-cools and stops glowing. To me, that is incredibly cool!

So basically you made a religious knife, since it's holy.

Who ever insures any of Integza's home/ property, liability, life, health, neighbors is the real legend here.

This is the perfect activity to do indoors

I don't get a chance to mess with aero engines too often, but I do work rather frequently with large gas turbine fuel systems at my engineering job. They've been using diffuser-type reverse flow fuel delivery systems for a while now with pretty interesting results! I highly recommend that you look up the General Electric DLN 1.0 combustor system sometime, Integza. Its an older design from the 80s but in terms of flame stability in high-flow combustion its really quite impressive, and being older a lot of the documentation is freely available online.

For a future video see if you can 3D print a battle axe or a sword with the same material and then put them to the test in some epic sløw mo shots.

you don't understand how much i wanna grab that knife and turn the pressure to max then just watch it go super saiyan in my hands

Glad to see Integza get back to his roots: almost lighting his ceiling on fire with unchecked open flames.

a temu ad? really? i really hope they paid you very very good

Oh my goodness... This is awesome! So here is a thought... Instead of a combustion chamber that pushes air... Push water... With hydrophobic coating on the wall... Then hydrolyze the water to browns gas... The browns gas can pass through... The water cannot and the water can be circulated as a better coolant for the combustion wall...

I remember back when rocket scientists were smart and didn't try to do every highly dangerous thing all at once for the admiration of randoms strangers they will never meet in life.

he literally made this sponsorship like "hi thanks for ur money temu im gonna maka a sarcastic ad for u" I LOVE THIS KIND OF IRONIY

Not Temu 😭

As a Metal 3D Printing Engineer, I can only say one thing; the things that are possible with this technology, sky is the limit.

I was thinking that I would love to see a fan driven, Nitromethane liquid rocket engine. With an aerospike nozzle, so it looks like the blackbird's engine. Great video.

"okay here's the bread, i am going to turn on the knife." words you never thought you'd hear from Integza 🤣

Electroboom: "Finally, A Worthy Opponent , Our Battle Will Be Legendary!"

Could this be used for active cooling and heat deflection on engine components?

Very excited to see where this goes. This was my first video I’ve watched from you and I’m hooked now

Integza just casually playing with a pretty big flame indoors is giving me anxiety :D

Bro made a rare fire knife skin IRL and an ultra legendary SUPERSONIC FIRE KNIFE SKIN

Making the holes be smaller and only on the edge cold make like a ligth edge.

You can also try doing a somewhat thin rocket nozzle that goes al the way to the end and returns to the center, cover all of it but the very center ( or end, for the nozzle to cool with the hydrogen) with coating the outside with metal so that the pores to the atmosphere are closed functioning more like a pathway for the hydrogen to pass by, just like the actual rocket nozzles, u can cool your nozzle while distributing fuel. These micro pore would probably work perfect

You should add a thermally resistive ceramic handle with a guard so it doesn't get to hot.

Is it a bad thing that I was on the edge of my seat watching you eat an entire dinner meal on camera? haha. I see the potential this tech has, and fully expect you to expand upon this.

5:10 this genuinely looks like some sort of demonic or magical energy enveloping the knife, especially with the sound accompanying it.

A suggestion for a video I think, would be teaching someone about rocket engines face to face and having them build one after a weekend being taught by you. And seeing the carnage when or if something blew up. I nominate myself for this experience.

Video idea: "A jet powered leaf blower" Dont know if its possible, but also the option to spit flames and burn the leafs😂

Brings whole new meaning to "like a hot knife through butter"... and bread, and cheese... HAHA!

If you get a lean (oxygen rich (air rich)) mixture going into the blade and run it for a few seconds then the metal should get hot enough to ignite the mixture within the knife leaving fully combusted exhaust, and the heat will be focused on the blade instead of making a huge 3 foot torch, so you could toast bread better You'll want to turn down the flow a bunch to keep the blade from melting You could also drill a hole through the handle, and insert a pipe to seal off leakage in the handle, and increase transmission speed/capacity to the blade

this video was like watching an unhinged Beakman from Beakman's world given free reign with dangerous science to build future weapons for some industrial complex

This channel has been such a good source of reference for 3d modeling post apocalypse weapons

Make a flaming broadsword that takes 2 cartridges in the hilt for a flame out the end!

You're really planning on bringing a weapon to San Francisco? Not just any weapon, but a literal flaming knife? Oh boy... good luck.

You looked like a kid in a candy shop already and then you come in with "you know what would be more intense? If I tested it with hydrogen." 👏🤣

I swear, your channel is a near constant barrage of super interesting forays into jet engines but this video was completely novel and exciting. Thank you for showing us this kind of stuff (and I'm happy for you that you get to do this, too)

ouch, a Temu ad. it's really time for creators to start vetting their sponsors properly.

i know this man is not done experimenting with this kind of 3D printed metal shizzle. And i will be here waiting for the next thing he does with it.

this is really going to reignite the 1000 degree hot knife videos

uff Integza.. An TEMU Ad? big oof on that... -.-

Integza needs to go back to all the jet engine ideas he had in the past and award the best one. It'd be like an award ceremony and a celebration for getting millions subs.

Suggestion: Make a Rocket Engine With A Metal Injector, Copper Nozzle And with the hole filled engine you used in your glass rocket engine video. Also a better idea would be to use fuel air impinging injector so it burn smoothly.

Integza is the only reason I got into 3d printing. He made it look so useful and cool.

That was awesome! I hope that you get it through security so I can see it at Open Sauce!

you should try to make a pulse jet engine out of the porous metal, you could seal the outside of the metal body to make sure all the gas only going inside the engine, this would allow for even spread of the fuel throughout the engine and possibly make new and very efficient engine. (from there you should put it on a rocket and launch it up to see what happens)

Interesting how $1,000,000.00 is written in Portugal. Very cool. This channel rocks.

You should make a future video about scramjets or making a brand new type of jet engine using the same technology as the knife

I'd love to see a video that explores other unconventional uses of 3D printing, and the potential they hold! So cool that all this came from a hiccup in the printing process!

You should absolutely do a giant axe or sword with this technology. A Battle axe could maybe even be self contained.

I wanna see a katana made out of this, right NOW! The version with the red blade and invisible flames will make a stunning sword

i NEEED to see someone make this same thing but in the shape of a sword

the fire knife cheese melting would be an amazing thing to see at a restaurant

What do you paint your ceiling with?

For a future video you need to make an electric bread knife slicer with this new knife 😮❤🍞🥖🔪
