Oh man you need to find a way to force molten "candy rocket fuel" out of the hot end of your 3D printer!!! or first try to 3D print a mold but then experiment with the flammability of different shapes. Talk to Elemental Maker about it if you are having too much trouble with where to start. and what about making some metal rocket nozzles or cases like it shouldn't be too hard to get some thin walled aluminum tubing and stuck a better sized hole at the end and since they ignite from the end make the internals tapered to match that?
Align your rocket vertically with your rail. By keeping the rocket next to the rail you are actually producing torque on rail because that thing wants to spin.
Serious concerns alongside a video idea: ABS is extremely toxic when burnt. There's a reason why most commercial ABS printers are enclosed and why many people who print ABS encourage building printer enclosures. And that's just melting it. You're burning the ABS and that's releasing even more chemicals into the air. Secondly, I'm pretty sure that your current test stand has way too much friction and way too much mass. Though your printer's linear rail prevents more friction than is necessary within the context of a 3D printer, that's still a lot more friction than necessary. And your rocket mounting method (aka a huge, heavy clamp), means that the moving portion of your rocket has a *lot* of inertia to overcome in order to actually move. These two things together meant that you have a massive wall that your rockets have to pass in terms of force before any movement will be shown at all. If you were to build a system that has less mass on the movement axis and lubricated your rail or replaced it with something that moves smoother at lower forces, you'd see significantly more movement on your rocket tests and be able to judge differences in speed, etc. far more easily. Thus video idea: combine both of these. Build an outdoor test stand designed specifically for testing your rockets. I know you hinted at something like this in the video, but I think you could make an entire video re: your process of building a test stand that is safe (health wise), smooth (rail wise) and light (mass / intertia wise). And the result would also be better, more visual test results for the rest of your videos!
I don’t normally comment, but yeah, ABS is vile... There’s no way I’d print ABS without an enclosure let alone burn it, and especially not inside. My heart skipped a beat when I saw him burning it in his attic?!?!?
@@makennasmith1477 Oh yes, definitely! This video showed that ABS certainly works alright as rocket fuel, but I don't think I'd ever burn it inside like that, let alone inside my own home! I really hope that attic has some windows that were opened after filming this section!! Honestly, he probably shouldn't be burning anything inside his attic, but the ABS was really the thing that worried me 😬
Well i dunno but maybe the pure oxygen helps helps burning off Most toxic components, on the Other Hand it also Melts the Engine in the outside so... Edit: I Just read Up on it and the biggest Problem seems to be ultrafine particles in which case the oxygen probably Made it worse
There are few ideas for improving hybrid rocket that I have. 1. You could incase whole solid fuel and nozzle in metal pipe of some sort, that would allow you to increase the chamber pressure that intern would speed up the exhaust gas that would produce more thrust. 2. If you know the energy density of your plastic filament and burn rate you can increase specific impulse (ISP) by controlling valves using Arduino and a stepper motor connected to the oxidiser valve. 3. You could make a nozzle from 3d printable ceramic resin, that would allow it to survive longer exposures to high temperatures and could be reused, also if the outer casing is made from steel pipe nozzle could be mounted on flex joints that allow it to gimble, but that is only after the problem of caring enough of oxidiser to power engine and also not too heavy for it to be able to lift off. Few tips that might help from my own research and experiences while I was active in our rocketry club before whole covid and all fun that came with it :D Use standard off the store pipe for the outer casing, you can easily drill through the end cap and fit nozzle and also use a high-temperature sealant for no high-temperature exhaust escaping around the nozzle and starting to eat solid fuel pellet/core. because we are engineering students we have all the tools like lathes and mills so it was a bit easier to weld and centre so we didn't have out of centre thrust. but you could also 3d print a centring guide for drilling in the centre of an end cap of the pipe. If you need help with calculations just send me a message on discord :) boksininkas_LTU [KARAS]#6196
well knowing that he has a welder he could try to weld something up. 2 cones with cut off tops welded back to back. cuz the ceramic cant hold high pressures, also it lets gas through its porous material...
I have a theme for a future video: upgrade your gas setup. For starters, you *NEED* a ball valve with a spring-close mechanism for each type to be able to quickly turn the gas off. (Pull the lever to open the valve; when you let go, it slams closed *instantly*.) You also need a more solid way to mount the cylinders and controls, so why not make a complete solution based on a toolbox? The cylinders can rest in the bottom and the levels/gauges/etc. can mount as a control panel in the tool tray. (The hoses can be stored in the lid, so the toolbox can be closed up with everything in it.) That way, you can have the whole thing completely portable, yet quickly set it up whenever, wherever you need to. You can even take it on the bus without being asked pesky questions.
Also isn't the thrust totally limited by the pressure of the O2 canister? This is why liquid engines have turbopumps. No matter how good the fuel and O2 supply, chamber pressure will never exceed the O2 supply pressure.
You should hook up the oxygen tank to a solenoid so you can wire up a dead man switch that cuts of the oxygen supply when you inevitably set the attic on fire.
It's just insulation behind the wooden beams ya know that stuff that's usually very flammable... He's literally making a rocket in his very flammable looking attic it's just a accident waiting to happen from safety ignorance and lack of common sense
My mom likes nasty tomatoes, how can I convince her to stop eating fruit from the deadly night shade family? You could try using a composite metal filament. The kind you bake out the resin and then sinter it in a high temperature inert gas ore reducing oven. Hmm maybe you need to build an oven first. I have seen people use a kiln like yours but had it like a Russian nesting doll with one segment full of charcoal to prevent oxygen from getting to the part. Maybe you could use tomato based charcoal? Codie's lab has some nice videos that are related to this.
To go along with this, I have always wondered if you could print with a copper material -- or just an electrically conductive one -- and 3d print electronics. I have always wanted to see a _fully_ 3D printed electric motor, although I think it is unrealistic I still think it would be amazing to try.
@@MrScorpianwarrior I have seen 3d printed motors which used normal magnet wire. I have also seen printed motors using conductive inks. ua-cam.com/video/YsSm65DAcCg/v-deo.html ua-cam.com/video/ZHX6LXzhkjo/v-deo.html Printing the winding which needs good conductivity and well insulated, it's a hard thing to do both of these at the same time. I think it won't be practical until we get molecular printers. Most motors also need good permanent magnets, and those can't really be printed with current tech.
Let's all just take a moment to appreciate the fact you're building highly flammable rockets in the attic of what I assume is your house. And wasps bother you more than accidentally burning a hole in the floor 😁

You’d benefit using some sort of intermediate valve between your fuel source and the flame. I say use a oxy/acetylene cut off torch for the ability to not only mix two gasses, but also have the ability to have the fuel sources on and off instantly.
@@rucker69 I’ve seen flames go up the hoses on oxy/acetylene, hence the main regulator on the bottle as well. When he has the oxy tank sideways is also worrying too.
Try to do Lost PLA casting. You 3d print an object, bury it and sand, and pour molten metal. The molten metal will vaporize the PLA and replace it resulting in a metal version of the 3d printed object. There are also wax filaments manufactured intended for this process.
This. Though, recently, there has been a similar thing but with ceramics. You print the item, dunk it into the ceramic, make the ceramic harden and burn out the plastic. With a bit of handywork you can get a lot more detail to it, though with one more step involved.
Interesting idea, I think you should build the fuel and the rocket separate, I think you're just burning your nozzle off super fast. So you should print a nozzle and case out of something that won't burn as much (perhaps ceramic) and the fuel should be an insert into said nozzle and body
I was wondering why he printed the nozzle and body continuous with the fuel too. He has made 3D printed ceramic nozzles already but getting them to stay attached to the rocket has been difficult. Threads maybe? Some ordinary thin-walled copper pipe and fittings would be a good place to start for the rocket body, with the ceramic nozzle threaded on after loading the fuel.
@@markfergerson2145 realistically he could also take that copper pipe and press it into something close to a nozzle anyways, then thread an end and put a threaded bushing in it that's from his pipe size to his oxygen fitting size, then it'd hold his fuel in and supply his oxygen through the fuel core, and allow for rapid testing of fuels
"those things you put on birthday cakes" are actually called sparklers and I have never seen someone put them on a birthday cake, the're usually just waved around at event with fireworks such as fourth of july or sometimes a new years event
@@steveskeletonneii6336 Fairly certain that's why he made sure that he's in a well ventilated room for doing tests that involve setting things on fire.
Print a ceramic test chamber with ceramic nozzle that holds the 3D printed fuel. Just print fuel cells and insert them in the ceramic engine for a reusable engine that won’t melt 😁
Hi, novice engineering student here and id like to recommend you try an elongated thrust nozzel made of ceramic or brass. The elongated geometry of the nozzel would provide more thrust by causing rapid acceleration of the gas/flame coming from the combustion chamber. Also print a hard outer shell of 100% fill and a burn core of abs at 75-90% in fill to achieve better surface area and more aggressive combustion
Video theme idea: creating an underwater propulsion machine. Or building my own DIY rocket engine thrust measuring device (I actually have a good idea on how that could be built).
i know right... also he's in the attic(heat/smoke rises) why not use an exhaust fan above?? he would be able to exhaust out the side of attic with inexpensive materials he probably has most of the parts lying around to build one lol
Funny you upload this nearly on my birthday and sing happy birthday xD Is quite a strange but wonderful coincidence that one of my favorite UA-camrs would upload this
I don't watch your stuff every day, or even every week. About once a month though I fall down a youtube Integza hole and watch 20 of your videos back to back. Today, is that day.
You could explore creating your own filliment with more... Desirable properties. Alternative suggestion, design a 3D printed rocket (including nozzle) that accepts sugar rockets as a sort of fuel cartridge. You could even rig up a way to pump oxygen through a sugar rocket!
Ayyy you actually wore your safety goggles the whole time! Now you just need to get an emergency cut-off valve for your propellant so you don't end up blowing your attic up.
It’s painfully obvious his family’s home insurance company has no idea what he has been doing in the attic. Reminds me of a story about a kid in the 90’s. Yes it was the early 90’s, I think, maybe it could have been the 80’s but I digress. This little American Boy Scout trying to earn a badge builds a damn breeder reactor in his moms shed in the backyard.
You should coat the plastic with fireplace sealant and carbon fiber. The fuel would be able to continue burning with no leaks and it would be fast to make.
The humble sparkler is not far from how the Russians ignite their rockets, even in the present day, they use PZU pyrotechnic devices (think giant match with a sparkler type head) to launch their Soyuz rockets.
" Polylactic Acid (PLA) is different than most thermoplastic polymers in that it is derived from renewable resources like corn starch or sugar cane" SUGAR CANE
@@Panda_Gibs yup. I barely print with PLA. For my applications I prefer abs or petg but even if it as a lower melting point I think pla is better suited for this application.
Use 10% filling on the chambers and parts of the engine that are hollow (maybe modifying the filling pattern to help with the flow) to give the engine more fuel to burn on. And making a metal or clay sheath where you can put the engines in, since you're using the same outside format for most of them, you could ideally use the same sheath for all the tests.
I was going to suggest a sheet metal sheath that way easy to produce (pair of tin snips and a vice) and diameter won't matter. Also it's cheap I mean economical😉
@@iczer01 that's basically what I had in mind when I said "sheath", although the clay might be a good option if you want safer shreds in case of an explosion.
This but i would also do something about the nozzle, it being burning as well doesn't help much. Maybe get some nozzle made out of metal or clay that you can attach to the sleeve and make the Burnable part like a solid stick just dropped into the sleeves. If the nozzle is made out of metal it should be easy to reuse, even if it got really dirty from the resin you could just burn it away or maybe use some acid if compatible with the metal.
Recycle your burned down models and when you use them again you can enrich them with sugar or wood petrol (when you burn wood and the gas condenses it's like petrol made of wood)
Yes... print it and put it in a compacted "green" sand. Heat it in your oven to burn/melt off the plastic and then cast the part. Depending on the metal you choose to cast the part you could easily braise it to anointing parts. Blam! No more leaking parts and longer test times!
What of you bought yourself one of those 3D Printer „waste Recyclers“ where you Melt down the plastic again, and With this you could enrich the abs plastic With Sugar!
The candle topper things look a bit like what people here in Iowa call "Sparklers", a type of firework that consists of a a long, thin metal rod, with about half the rod coated in a layer of a grey, flammable substance. When lit, the grey substance gives off a bright light, and gives off sparks as it slowly burns along the length of the rod... In case it wasn't obvious to anyone reading this, you're supposed to hold the end of the rod that doesn't have any flammable stuff on it.
Yeah, we just call them sparklers in the UK too. It's some sort of magnesium/aluminium with potassium nitrate paste. You dip the rods into it, let them dry and light them up.
There is a Magnetic filament you could use to 3D print Bullets or little Rockets and fire them in your Railgun. You know.. the Railgun you should be working on!
To get the fuel to burn more entirely you need a metal casing. In highschool I was in a rocket club that got funding and advice from NASA. We had commercialy produced hybrid engines that had a metel casing and acrylic fuel. Plastic is actually pretty energy dense.
5:30 Yes, when sugar melts it becomes caramel. Not exactly the same as the caramel that gets put in sweets, but it is caramel. Onions have sugar in them, hence the cooking method: caramelisation.
You could try fitting the fuel into a ceramic shell that lets the fuel burn completely maybe you could try and make nosles that can be screwed onto the creamic body or otherwise be attached and only make the fuel out of abs(you could also try pla)
Hey Integza. The sparkly things you put on birthday cakes are called "sparklers" in English. Also I've never seen them put on birthday cakes anywhere but in Portugal. But I digress. Rocket on!
Trying to power a RC Plane or Car with such an engine would be a cool video! and you could try to use a scale to measure the thrust for your Rocket Engines! Your pronounciation of "Dankeschön"was actually pretty good :)
Those sparkly birthday cake things (which we actually don’t put on birthday cakes in the US) are called “sparklers” in English. I know, it’s not exactly a creative name, but it does what it says on the tin.
@@VulcaNtGoF I’m in Maryland, literally an hour’s drive from Delaware without traffic. I’ve never seen a birthday cake with sparklers on it. Maybe it has something to do with fireworks regulations in Maryland?
you should try to use variable infill+ Gradient Infill, so you get more fuel, in a small place. Were in the worst case you slice a separate cylinder with another infill than the nozzle, and then modify the g-code to combine them. PS I would love to get a response from you Integza.
I liked the bit at the end with your sister (are both of them your sisters?) Nice change of pace, I got a laugh out of it, you should include them more.
You should add external threads to the outside of your "engine" then print a bell nozzle that can thread on. All tests that I have done actually worked pretty well.
Rocket propulsion engineer here - First thing, 3D printed fuel is very much a thing. In fact, many test labs use ABS to test different designs, you are on the right track there. What I noticed most about each of your designs is that they don't account for erosion as the engine burns away. That is why you kept getting chunks blowing out. For future designs, think about what shape the inside will look like after half of it has burnt away. Will it still look the same? Second is the thrust. Rocket nozzles are specifically designed to maximize the amount of thrust based on the pressure inside the chamber. What I noticed about your designs is that they are WAY over expanded. You could get a lot more thrust out of all your rockets if you made the cone a little more narrow. Given that you are burning a fairly low pressures, your cone does not need to widen much at all.
You should collab with the plasma channel try to make a glider powered by ionic wind and you should also try using other solid fuels like black powder mixed with oxygen in a stronger rocket chamber, like a steel pipe.
Future video (series!) idea: Colin Furze and Integza collab doing a fully fabricated rocket build - ending in an attempt to reach the Karman line... and then livestream the launch and the descent!
Agreed, definitely wear a full respirator approved for VOCs when burning plastics! I'm not sure exactly which type would be needed, but if it stops the odor, it's probably good enough
Yea produces hydrogen cyanide which itself is pretty dangerous but I think with good ventilation the amount shouldn't be dangerous but I also think that's intended to be typical exposure from printing it and such not using it as a combustible fuel.
This needs more upvotes. Burning plastics in general isn't exactly healthy and I don't think that there's enough ventilation in that attic. A good respirator mask would be highly recommended.
"Maria, the neighbor's building missiles in the attic again! Get me my ultramar rifle!" I suggest moving out of the attic with all this knowledge, make a basic small rocket to go up and come down on a wee parachute. That being said, you'd probably just start katyusha'ing the neighborhood. But you might get sponsored by the Portuguese artillery command, so there's that!

@@Davinator2662 I'd worry about the copper absorbing too much heat from the flame. Still it could be worth a try. Integza, you reading this stuff?

"those things you put on birthday cakes" are actually called sparklers and I have never seen someone put them on a birthday cake, the're usually just waved around at event with fireworks such as fourth of july or sometimes a new years event
I had a buddy stick one in a cigarette on me once. I didn't know it, and lit it while driving
you should be amazed at the creativity of the english language to know that it has named those sparkly things sparklers.
Almost as creative as how every single driver on the road is named "Jerkoff!" in American English.

Print a ceramic test chamber with ceramic nozzle that holds the 3D printed fuel. Just print fuel cells and insert them in the ceramic engine for a reusable engine that won’t melt 😁
was about to comment that, could plate it in copper too!
Was thinking the same. Any nozzle you 3D print out of the fuel will burn up in seconds
Hi, novice engineering student here and id like to recommend you try an elongated thrust nozzel made of ceramic or brass. The elongated geometry of the nozzel would provide more thrust by causing rapid acceleration of the gas/flame coming from the combustion chamber. Also print a hard outer shell of 100% fill and a burn core of abs at 75-90% in fill to achieve better surface area and more aggressive combustion
"Keep burning."
"But we're out of-"
*I said we burning today*

Video theme idea: creating an underwater propulsion machine. Or building my own DIY rocket engine thrust measuring device (I actually have a good idea on how that could be built).
"one of those sparkler things you put on birthday cakes, I dont know how to say it in english." Sparkler, you got it... its just... sparkler. lol

i know right... also he's in the attic(heat/smoke rises) why not use an exhaust fan above?? he would be able to exhaust out the side of attic with inexpensive materials he probably has most of the parts lying around to build one lol
Funny you upload this nearly on my birthday and sing happy birthday xD
Is quite a strange but wonderful coincidence that one of my favorite UA-camrs would upload this
considering the view count almost 900 people watching this video are celebrating their birthday when watching it.
I don't watch your stuff every day, or even every week. About once a month though I fall down a youtube Integza hole and watch 20 of your videos back to back.
Today, is that day.
Yea same lol
hoard them together until one day you watch them all. make sure to have some snacks
Estes vídeos são incríveis. Fico contente que há um canal português com tanta qualidade
Sou brasileiro mas também me emociona quando eles acidentalmente falam português! 🤣
You could explore creating your own filliment with more... Desirable properties.
Alternative suggestion, design a 3D printed rocket (including nozzle) that accepts sugar rockets as a sort of fuel cartridge. You could even rig up a way to pump oxygen through a sugar rocket!
Ayyy you actually wore your safety goggles the whole time! Now you just need to get an emergency cut-off valve for your propellant so you don't end up blowing your attic up.
I have this scary feeling that one day Integza will blow the roof off of his house.
Integza: "So, that poses the question: Can I turn my house into a rocket?"
It’s painfully obvious his family’s home insurance company has no idea what he has been doing in the attic. Reminds me of a story about a kid in the 90’s. Yes it was the early 90’s, I think, maybe it could have been the 80’s but I digress. This little American Boy Scout trying to earn a badge builds a damn breeder reactor in his moms shed in the backyard.
@@kwhp1507 oh yeah
@@kwhp1507 that's why you don't have insurance, so you can do whatever you want
Also this roof looks pathetic as hell
You should coat the plastic with fireplace sealant and carbon fiber. The fuel would be able to continue burning with no leaks and it would be fast to make.
As far as I'm aware, the sparkly thing is straight up just called a sparkler.
And Foguetes Mágicos in Portuguese apparently.
In germany it's "Wunderkerzen"
The humble sparkler is not far from how the Russians ignite their rockets, even in the present day, they use PZU pyrotechnic devices (think giant match with a sparkler type head) to launch their Soyuz rockets.

" Polylactic Acid (PLA) is different than most thermoplastic polymers in that it is derived from renewable resources like corn starch or sugar cane"
SUGAR CANE
I can confirm that PLA not only prints odorlessly, it also burns odorlessly. Until you put it out and it smokes. Then it smells like burning sugar.
@@Panda_Gibs yup. I barely print with PLA. For my applications I prefer abs or petg but even if it as a lower melting point I think pla is better suited for this application.
And would melt in a stream of goo fast. LOL
I was thinking exactly the same!
I think a smaller project like a Emergency stop for the oxygen would be potentially handy 😅
Awesome stuff!
inline ball valve wouldn't hurt
Use 10% filling on the chambers and parts of the engine that are hollow (maybe modifying the filling pattern to help with the flow) to give the engine more fuel to burn on. And making a metal or clay sheath where you can put the engines in, since you're using the same outside format for most of them, you could ideally use the same sheath for all the tests.
yeah, the gyroid infill could be fun to experiment with this
I was going to suggest a sheet metal sheath that way easy to produce (pair of tin snips and a vice) and diameter won't matter. Also it's cheap I mean economical😉
@@iczer01 that's basically what I had in mind when I said "sheath", although the clay might be a good option if you want safer shreds in case of an explosion.
This but i would also do something about the nozzle, it being burning as well doesn't help much. Maybe get some nozzle made out of metal or clay that you can attach to the sleeve and make the Burnable part like a solid stick just dropped into the sleeves. If the nozzle is made out of metal it should be easy to reuse, even if it got really dirty from the resin you could just burn it away or maybe use some acid if compatible with the metal.
Love how this guy tries his best to make his videos funny and understandable by also trying his best at English. Keep up the good videos.
Recycle your burned down models and when you use them again you can enrich them with sugar or wood petrol (when you burn wood and the gas condenses it's like petrol made of wood)
I think it is about time you start casting some of the parts
Yes... print it and put it in a compacted "green" sand. Heat it in your oven to burn/melt off the plastic and then cast the part. Depending on the metal you choose to cast the part you could easily braise it to anointing parts. Blam! No more leaking parts and longer test times!
@@maybethistime6761 anointing?
You should try to power a Tesla turbine with one of your rockets! Try and measure its rpm to see if you break your record.

What of you bought yourself one of those 3D Printer „waste Recyclers“ where you Melt down the plastic again, and With this you could enrich the abs plastic With Sugar!
The candle topper things look a bit like what people here in Iowa call "Sparklers", a type of firework that consists of a a long, thin metal rod, with about half the rod coated in a layer of a grey, flammable substance. When lit, the grey substance gives off a bright light, and gives off sparks as it slowly burns along the length of the rod... In case it wasn't obvious to anyone reading this, you're supposed to hold the end of the rod that doesn't have any flammable stuff on it.
Also call them sparklers in New Zealand
It is magnesium and burns very hot.
Yeah, we just call them sparklers in the UK too. It's some sort of magnesium/aluminium with potassium nitrate paste. You dip the rods into it, let them dry and light them up.
They're "Sparklers" in New England, too.
So basically the whole (relevant) world agrees they’re called Sparklers and this is just something the Portuguese got wrong.
3:29, Integza just created a Paradox. Godamn.
In your next video make a car that's powered by a rocket engine.

Worse, you look at them after pissing them off so they scream and say you hit them
There is a Magnetic filament you could use to 3D print Bullets or little Rockets and fire them in your Railgun. You know.. the Railgun you should be working on!
To get the fuel to burn more entirely you need a metal casing. In highschool I was in a rocket club that got funding and advice from NASA. We had commercialy produced hybrid engines that had a metel casing and acrylic fuel. Plastic is actually pretty energy dense.
The moment when they said it smeels like caramel and inetzga just looks at the rocket like he wanna lick it so bad....
He loves his rocket and wants to lick it so bad, but he'd rather watch it pop everywhere instead.
What I have learned from this video:
If it sounds like a demon, it probably has a lot of thrust

Same. And now he's burning stuff that probably gives off very nasty fumes.
@@SamFisk Extremely nasty, both when 3D printed, and when burned in an attic with a manually controlled LOX feed.

Yes, when sugar melts it becomes caramel.
Not exactly the same as the caramel that gets put in sweets, but it is caramel.
Onions have sugar in them, hence the cooking method: caramelisation.
You could try fitting the fuel into a ceramic shell that lets the fuel burn completely maybe you could try and make nosles that can be screwed onto the creamic body or otherwise be attached and only make the fuel out of abs(you could also try pla)
Hey Integza.
The sparkly things you put on birthday cakes are called "sparklers" in English.
Also I've never seen them put on birthday cakes anywhere but in Portugal. But I digress. Rocket on!
They are just an excuse to burn things.
You should try to make a metal Cnc/mill so you can make things out of aluminum.
He should just use steel piping from the hardware store for the rocket.
Man !! you are one step away from changing human history of rocket science
Trying to power a RC Plane or Car with such an engine would be a cool video!
and you could try to use a scale to measure the thrust for your Rocket Engines!
Your pronounciation of "Dankeschön"was actually pretty good :)
It would be awesome if you got some metal working tools and made a rocket engine!
I think you should build a rocket powered plane

Those sparkly birthday cake things (which we actually don’t put on birthday cakes in the US) are called “sparklers” in English. I know, it’s not exactly a creative name, but it does what it says on the tin.
Perhaps not in the part of the US you're in. Happens here in Delaware. 🤷🏻♂️
@@VulcaNtGoF I’m in Maryland, literally an hour’s drive from Delaware without traffic. I’ve never seen a birthday cake with sparklers on it. Maybe it has something to do with fireworks regulations in Maryland?

12:37 "WHO NEEDS A FIRE EXTINGUISHER WHEN YOU HAVE MY LUNGS"
Id realy like to see you assemble some of your Rocket ideias, like your Turbojet engine with a nozle Spike and a hibrid fuel
^^
you should try to use variable infill+ Gradient Infill, so you get more fuel, in a small place. Were in the worst case you slice a separate cylinder with another infill than the nozzle, and then modify the g-code to combine them.
PS I would love to get a response from you Integza.
Holy shit this sounds like movie scientific jibber-jabber and I love it
And here I just suggested making ribs or something inside to increase surface area. Seems like you know a lot more about how slicers and such work.
I liked the bit at the end with your sister (are both of them your sisters?) Nice change of pace, I got a laugh out of it, you should include them more.
they are so cuteeee
12:21 when i used to turn on the old TV for SNES or Sega Genesis
You should add external threads to the outside of your "engine" then print a bell nozzle that can thread on. All tests that I have done actually worked pretty well.
I was thinking this exact thing. Or try making a resumable jacket.

Theme for a future video: therapy sessions for integza's future depression for going blind.
Rocket propulsion engineer here - First thing, 3D printed fuel is very much a thing. In fact, many test labs use ABS to test different designs, you are on the right track there. What I noticed most about each of your designs is that they don't account for erosion as the engine burns away. That is why you kept getting chunks blowing out. For future designs, think about what shape the inside will look like after half of it has burnt away. Will it still look the same?
Second is the thrust. Rocket nozzles are specifically designed to maximize the amount of thrust based on the pressure inside the chamber. What I noticed about your designs is that they are WAY over expanded. You could get a lot more thrust out of all your rockets if you made the cone a little more narrow. Given that you are burning a fairly low pressures, your cone does not need to widen much at all.
what about if you get out of your workshop... put one of those engines in a simple, small and light car and let it explode or burn in the way.
You should collab with the plasma channel try to make a glider powered by ionic wind and you should also try using other solid fuels like black powder mixed with oxygen in a stronger rocket chamber, like a steel pipe.
I just noticed the Alan Rickman photo next to Nikola Tesla. This was amazing to watch!
This guy is the funnest insane person I have yet to find on UA-cam. I hope he does not blow himself up. The content is too good.
Future video (series!) idea: Colin Furze and Integza collab doing a fully fabricated rocket build - ending in an attempt to reach the Karman line... and then livestream the launch and the descent!
They gotta make this happen
@@mattpearce4313 RIGHT! Get your friends, neighbors, and family to like it! Let’s us the fans make it happen!!
Future video idea:
3d print a better setup for testing your rocket thrust
You could make a "replica" of the SRB of the space shuttle, with the same way of working and the same solid fuel
4:38 i can think of something else it looks like
good to see you wearing eye protection. hope my comment on your recent video inspired you! great work!
Your German pronounciation was actually really good👍👌
True
I thought burning ABS produced some toxic fumes... for what I am reading is not THAT bad, but still be careful bro! Nice video as always.
Agreed, definitely wear a full respirator approved for VOCs when burning plastics! I'm not sure exactly which type would be needed, but if it stops the odor, it's probably good enough
Yea produces hydrogen cyanide which itself is pretty dangerous but I think with good ventilation the amount shouldn't be dangerous but I also think that's intended to be typical exposure from printing it and such not using it as a combustible fuel.
This needs more upvotes. Burning plastics in general isn't exactly healthy and I don't think that there's enough ventilation in that attic. A good respirator mask would be highly recommended.
You could put the fuel inside a ceramic tube with a ceramic nozzle to avoid it losing thrust as it melts/burns away.
I almost want to see that rocket on a tiny drag car. I wonder just how far and fast it would go
"Maria, the neighbor's building missiles in the attic again! Get me my ultramar rifle!"
I suggest moving out of the attic with all this knowledge, make a basic small rocket to go up and come down on a wee parachute. That being said, you'd probably just start katyusha'ing the neighborhood. But you might get sponsored by the Portuguese artillery command, so there's that!
