@@lisandropena9403 you're tomatoes?
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?
@@lisandropena9403 EVIL
"Looks like glaze you put on cake" I would have gone with something else but okay
I watch both if your channels a d you both are amazing
Now that's just inappropriate. I like it
you're still alive after destroying the local drug dealers house?
Hi
Whatever you're thinking of, I think its technically still a glaze
Put tomato concentrate into the resin, then you can use the blood of your enemies as rocket fuel
I like the way you think Joel !
Better yet you can use it in every project you make like an rocket engine made entirely by tomatoes blood
@@integza just use the entire tomato! use the plant itself for the rocket stand for launching!
What we don't won to celebrate tomatoes everybody stay calm
@@matteoaversa2726 you could theoretically make fuel out of tomatoes, just like (wood gassing
"Don't smoke" he says while burning plastic in an enclosed space with no respirator xp
2:11 so close. Accidentally almost called them what they are - - Sparklers.
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.
This!! I was thinking the same
yeah i mentioned this a while back, that torque prevents it from moving linearly
Yes!
I was thinking the same thing
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
4. Be more safe and logical, don't play with fire and high pressure systems like it's your friend
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...
it's criminal how under-subscribed this channel is, he is like a mad rocket scientist from the movies. so glad youtube recommended this to me.
As a type 1 diabetic the joke @ 4:32 was freaking hilarious! Thumbs up from me sir!
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
Trying to figure out why this comment is so far down the page. This is pretty damn important info
UV resin is also incredibly toxic when uncured so I imagine it's rather unhealthy to burn it too.
"Sparkler" is the sparkly thing you put on birthday cake. love the video
"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
The editor version of you giving the other you in the past an idea is just glorious!
The most ballsy thing about these experiments is the lab location - under a wooden roof xD
not wooden. you can see the tiles
@Landon Garciasmith good one, but what about tulips, hmm?
@@OliverFlinn tulips on deez nuts lmaoo
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
also no respirator..... would not want to breathe resin VOCs
might it be an idea to use a ball valve so that you can shut off the oxygen faster and you don't burn down your attic?🙃
it could be remotely controlled by an arduino-bluetooth setup..
@@dans-designs or by tomato slave
@@dawidhojny4887 tomatoes are disgusting but so is slavery.
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.
@@Jacob-gg1rt Integzabot 2.0
your channel has grown so much since i first started watching your videos! great video as always! keep up the amazing, unique work and high charisma
Me at the start of this video: Man he must have a special fire safe room for this testing
Me at 11:06: Is that a wooden roof?
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.
"Keep burning."

Tuga ta em todo o lado, continua com o bom trabalho
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.
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.
Melting the metal isnt terribly hard to do either, especially if you use something like aluminum which has a relatively low melting point
I think he already tried, I don't know...
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
@@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?
Man !! you are one step away from changing human history of rocket science
Youre freaking awesome glad I found your channel
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.
Yeah, I was wondering what the risk is that the flame burns back to the tank
@@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.
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.
th-cam.com/video/YsSm65DAcCg/w-d-xo.html
th-cam.com/video/ZHX6LXzhkjo/w-d-xo.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.
*sinter it
@@ansleylobo8042 Thx
@@zyxwvutsrqponmlkh3 phase induction motors don't need permanent magnets. The efficiency might suffer though.
In English, the sparkling things are just called sparklers, but your analogy about them works too
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! 🤣
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).
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 😁
i bet you he is going to use the flamey end of the rocket to burn those wasps
Or ceiling lol
There is very little difference between rocket fuel and explosives...
Us: Integza! Where do you get these crazy ideas!!
Integza: FUMES!! Burning plastic cleanses the sinuses and sharpens the mind, plus it keeps away the bees and tomatoes! 🤪
Houses in Portugal are made of brick and mortar they don't burn like American houses.
How have I only just come across this channel!! It's amazing
Of all the places to do this. An attic full of insulation is by far the best

Nice! Looking forward to the follow up

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.

Okay, just found you and you sir have won me over! Subbed!
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
Almost every time, when I starting to watching video on this channel I think: "Nooo... It can't be! He can't do this" But at the end of video: " He did it... Again!" :))
Bruns I did a thing and integza?...am I dead?
А интегза никто не переводит?
Bruns' rockets are awesome :) отлично, благодарю вас Брюнз!
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
Brilliant, I love outside of the box thinking
To increase the efficiency, i would model a thin tube of material through the fuel body to channel the oxidizer towards the end at first, and slowly shifting backwards as the tube burns
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
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!
This was one of the best episides yet
thanks 4 your passion mr.
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.
A cool idea to try would be to print a solid propellent grain in one go by adding an oxidiser in the resin (KNO3), the resin itself is fine enough reductor so you do not need to add sugar. This could give you a lot of control over grain geometry, and you could make it fit in any shape pressure vessel. I would recommend a pretty thick piece of PVC tubing or a little thinner aluminium/steel tubing, put a thin insulator between the grain and the tubing to prevent burning your PVC to much or melting your aluminium.
you are insane! thanks for the video!!!!
Bom trabalho com estes vídeos, realmente é um canal com qualidade continua com o bom trabalho!
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 TH-camrs would upload this
considering the view count almost 900 people watching this video are celebrating their birthday when watching it.
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.

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!
One that actually works and can proceed with testing. Well done
So it turned out you were doing the right thing all along. What seemed like failure was actually successful
Love your videos, very funny and enjoyable. I would like to see you use some safety precautions though. Especially since you are burning some resin, it may be a good idea to wear a respirator.
Keep the good work going.

@@DavidGarcia-nx2gj we need some Presto logs like the ones in the locomotive from back to the future
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.
This guy is the funnest insane person I have yet to find on TH-cam. I hope he does not blow himself up. The content is too good.
Hey Integza.
The sparkly things you put on birthday cakes are called "sparklers" in English.

3:29, Integza just created a Paradox. Godamn.
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.
@@sakelaine2953 except for those drivers named "motherfskr."
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.
Nice video, you have a new subscriber!
Saludos desde España!
You could make a metal housing with a nozzle that compresses the output thrust therefore making more thrust and more use of the fuel. Make the housing two parts held by screws so you can replace the fuel core.
love your videos integza
Your second point is exactly what I was thinking too.
" 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!
Great job
You rock
This is pretty interesting, you got yourself a new subscriber
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.
I think you should build a rocket powered plane
ya i swear he’s gonna end up 3d printing a plain
@@noahwaaga5079Yeah no doubt
12:21 when i used to turn on the old TV for SNES or Sega Genesis
If you want better thrust you must focus fire in a spot and cement that spot with steel (or idk maybe a lighter material that wont burn down easily
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!

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.
@@leelo3252 why do all German words sound like some evil weapon from the underworld dimension lol
@@supermaster2012 do you think this sounds evil? Lol

Future video idea:
3d print a better setup for testing your rocket thrust
rocket engine- reusable pvc based holder for components. hybrid engine that uses nitrous charges (like for whip cream) fed into a tube made of wax as the solid propellent. using a thin plastic burst ring to begin the injection of the nitrous into the wax motor upon ignition. the trick is controlling the amount of nitrous that comes out once the burst ring has melted.
People don't seem to grasp the implications of this experiment, Solid fuel boosters not leaving trash behind, minimising mass whilst maximising fuel and thrust. Truly fascinating.
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.
Those names sound like candy crush combos! Can u guys imagine the smell of candy over there?! Such a cool vid!
Very interesting concept
Solid rocket segments are often very different shapes to provide for some variable thrust over the life of the motor. You may get some extra thrust by looking at the layouts.
Also, a theme for a video - How to Set Fire to your House by Setting of Explosives in your Attic. lol, but seriously you should be doing this outside, away from flammable things like houses.
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 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)

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.
