#rocket #engine #3dprinted
Video Idea: 3D print some rocket powered toy cars and race them against each other (as a way of measuring the thrust of the rockets)
3d print rocket fuel cars and light them on fire for science
I concur! Rocket powered 'slot cars' would be a fun video
I have footage of that, although we used store bought rocket engines.

Never mind, don't ball mill ammonium perchlorate. Forgot how bad an idea that is. K nitrate will work much better if milled though.

You're welcome. I still would love to see the video XD
@@Argosh 😆 I liked your way of pointing it out
Hello!
COLAB WITH NIGHTHAWK!!!!!
His scale setup is also weighing his rocket, as well as measuring it's thrust. Since the fuel is being converted into gas.. the weight of the rocket goes down, making it look like he has negative thrust.
Video idea: make a rocket test stand that properly measures the thrust it produces! Beats a kitchen scale and it would be a fun project to watch.
Tomatoes are disgusting!
good idea. Copy something from genius Matthias Wandel of woodgears.

Integza, you could try spiraling the fuel grain instead of having it be a straight bore, that might help it burn less chaotically.
I'm wondering if you could 3d print a multi-tool, it would be interesting to see what kind of an edge you could put on a ceramic 3d printed blade.
you mean like in a vortex cooled engine ?
The spiral might introduce an uncontrollable spin. For a firework it would be cool but rocket engine tech is to get us as passengers safely up into space. 🤔😆

ngl what im thinking that is happening is the first solid fuel igniting then the second seperately because the sparkler goes and ignites the first before getting pushed out so maybe gun cotton inside the fuel?
after you've nitrated the cotton, dissolve it in a solvent and reconstitute it. The surface area will be lower, so the burn rate will be more manageable.
Video idea: create a launchpad for 3d printed rockets and measure how high they will fly using different rocket nozzle designs+
And: Tomatoes are disgusting🍅🍅🤢
I 3D Print the connector on my launch pad's and then use a metal plate as a blast deflector, and 20mm PVC conduit for the legs. And 3,2 mm brazing rod for the launch rod, 1 meter, or 3 feet for the small rockets.

Wow, your explanation of how a de Laval nozzle works was simple and effective. The visual aid was very helpful.
The progress on the rocket engines is increasing exponentially and always entertaining 👏😎 Looking forward to the next one! 😉
For your next project you should 3D print a "World Peace" button. Sure it may not work, but you never know!
3D print a mini A380 engine?
5:15 It's my understanding that the gas heats up in the chocking point, it can't gain speed so the energy goes into heating up the gas, when you expand the nozzle the gas is able to expand and the speed increses.
ScottManly explains this very well on his Hypersonic wind tunnel video, go check his channel, I think you may like it
yeah, now that make sense to me, the gaz can't gain speed so it heats up, and has you let it expand, that extra heat is converted back into kinetic energy.
Video Idea: Try to make APCP as a printable propeller, this would create much much higher thrust. Then insert the printed rocket motor in a 3d printed shuttle model like this you could create a semi accurate test flight of a miniature shuttle.
Video idea: Mostly for visuals, use an old school kitchen scale with an analog interface. You could see the movement in real time. Most have a clock like interface.
Hey Integza, I make rockets every year (Guy Fawkes) in the same way commercial ones are made. The sugar KNO3 works fine (a small addition of sulphur helps) in a card tube. The grain is also the combustion chamber. I use builder's plaster filler to make the nozzle by laying it over a former. A tube shaped whole works well. I use a metal rod as a former.
Those oscillations in your burn were caused by two things, 1) the shape could be slightly inconsistent and 2) Up to a certain limit the rate of burn is proportional to the pressure in the chamber. So everything gets exaggerated.
The boosters for the shuttle are much the same. They use rubber and aluminium powder as the fuel with perchlorate as the oxidiser. The core is a simple tube. P.S. Have you heard the story about the boosters and the size of a roman horse's butt? let me know...
nice ngl i was thinking
that what was happening is the first solid fuel igniting then the second seperately because the sparkler goes and ignites the first before getting pushed out so maybe gun cotton inside the fuel?
Suggestion: Go get some gunpowder that is "smokeless powder" (smokeless powder is nitrocellulose). Dissolve the smokeless powder in acetone. Be sure to stir it thoroughly for good consistency. The result you will have is a gooey fluid to paste onto things, or pour into things. If you need it to be thinner, add more acetone; if you need it to be thicker allow the acetone to evaporate out of it. Once it is on, or in, whatever your using it for, allow it to dry THOROUGHLY for all the acetone to have evaporated out of it. The end result will be a hardened pyrotechnic coating or filling. I'm not sure how well it will work if you mix it with resin, but that's up to you to find out.
And I am with you, tomatoes are disgusting. Have fun!
@LabRat Knatz true, ping-pong balls are made out of nitrocellulose, and I had a lot of fun in my childhood lighting ping pong balls on fire. But using smokeless powder as the core ingredient is a lot easier than grinding up a bunch of ping-pong balls.
INTEGZA, if you don't believe me about this simple recipe, just Google a little bit of research into it. Trust me. You're going to have fun with it. And for added enjoyment, add a tiny bit of powdered aluminum for pizzazz.
Very cool. From what I've researched, I think in general it's just going to be a problem until you can find out the perfect mix of oxidizers and fuels that can be printed because I know that they typically moderate ammonium perchlorate with other chemicals to control the Burn Speed and I'm sure that NASA has multiple documents on it they use a couple different kinds of plasticizers that also have moderation capability
well, mythbusters found the perfect misture for air + water bottle rockets once, it was 1/3 water 2/3 air and a bike pump.
just had a stroke trying to read this
You can read the exact ratios on Wikipedia, but they use PBAN as fuel, and this resin is quite different. But they do use iron oxide as a catalyst for the engine, and aluminum powder. IDK if PBAN is safe to 3d print (probably isn't) but there are some less chemically volatile stuff that gets better performance than the resin used here.
@@Scyth3934 lol, welcome to the nerd corner. We say stuff that either is concise or a long essay that English teachers want you to write in 10 minutes.
@@rocketcello5354 yes, pban+ap+ferric oxide+aluminum in just about every solid stage motor out there.
In my mind you'd just 3d print a mandrel or similar to asssit the grain casting, not printing the grain itself as the aluminum is so important to the mix.
Cannot believe I'm finding this channel just now, this is by far my favorite engineering channel now.
Integza, thanks for using my battleship nozzle idea, and the cause of the pulsing and under performance of the engine is because the engine is getting chocked, either by inefficient burning causing residue to block the nozzle ( which may be fixed by having the nozzle side down ) or by the nozzle being over constricted ( which I believe is what caused the sputtering )
Add aluminum powder to the mix. That should improve the performance. Perchlorate, aluminum and rubber is a solid rocket fuel. So you would have perchlorate aluminum and resin should perform decently if you can get it to print.
adding aluminum powder would mean adding more perchlorate, and the resin already has too much stuff floating in it
I think you need a thicker resin for that
Heh and if you just mix the aluminum and perchlorate, you get flash powder for firecrackers. Win-win

7:11 "This is a grotesque oversimplification."
Thank you for saying this. 😂
Video Idea: it'd be cool if you used a raspberry pi/Arduino to make a code-able and remote ignition system. Be cool if you used step-up transformers and just send a plasma channel level arc through the combustion chamber to set the fuel. Also again, code-able. And if you when back to using propane and O2, you could have a pulse jet engine by simply setting an interval. All this could be down through Raspberry pis gpio and running it on something like MU (Python) or Node.js (JavaScript).
I actually think this wouldn't be too hard to do. There's not really any need for soldering and most of the heavy lifting would just be through code. And there's more then enough references online for this stuff. Like node.js blinking light, just use the same code but instead of an LED you can use your choice of ignition system
You could also build another test stand for this and add a pressure pad (FSR) to feed data into a pi and get very accurate pressure/thrust readings
Video Idea - Since all of us love rockets and some of us have 3D printers, your followers should try designing rocket nozzles (and try them out if they dare) and submit them to you somehow to see which rocket nozzle performed the best! Heck maybe a tomato shaped rocket nozzle would be the winner 😉
Try stacking a bunch of these together to make an auto detatching multistage rocket. As the fuel burns up it lights a second stage which burns/detaches the previous stage
Presumably the holy grail would be to print rocket nozzles in with the fuel so it's more self consuming than staged.
(Assuming nozzles that burn, just slower than the fuel)
I don’t know if you can get a good convergent nozzle that way but I know that a short unrestrained length of some fuses will fly many meters when burned. The core (slow black powder) burns faster than the jacket (cotton/lacquer) and directs the gas as it burns
A drone with rockets to get high speed!
some person did something similar with a extra motor and a FPV drone. just add a rocket, everything is better with rockets!
It looked like the bottom cap of the rockets were melting while being tested, resulting in deformation as it went. That might be introducing some inaccuracies in your force measurements.
And the fuel is burning up as the test is running, resulting in a lower reading. The rocked should be placed horizontally when testing it's force for more accurate measure.
An important part of rocketry you tracking the telemetry and performance of the rocket in-flight.
A video stress testing potential sensors / data loggers could be interesting, and perhaps you could make a custom PCB via your sponsor to integrate them?
Hi Integza, Thanks for another great video.
I feel something needs to be done with all this thrust, maybe try your best thrust engines on some rokets and test which one comes the furthest or highest!
Video idea: A comparison/explanation of store-bought rockets and 3d printed rockets and the difference in power, chemical makeup, etc
Idea: still along the lines of 3d printed rocket grains, instead of using a mixed resin as the grain fuel, use regular FDM with ABS/PLA/PETG. Using these FDM plastics, you can pass a gas like oxygen or another gas oxidiser through the grain and the PLA essentially turns into rocket fuel. Compare the different power outputs of each FDM plastic type, and the different gas oxidisers!
Pretty sure he has a video doing exactly that
Video idea: layer the fuel in this way: faster burning = inner layer, slower&longer burn = outer layer. Nitrocellulose should be the inner layer, maybe phosphorus as the second layer, and keep layering until you get to rocket sugar or something more slow burning. That should make the rocket burn fast, and when it's turn for the outer fuel layers the temperature inside the rocket chamber should be big enough to burn it fast enough to work well as a rocket. If faster burning fuel were to be in the outer layers, the rocket would explode because the pressure generated would be too great for the chamber. (So the idea is to keep constant pressure with the increasing temperature by picking slower burning fuels as time goes on).
Or the rocket explodes anyway and instead of rocket pieces everywhere you have burning fuel too🚀😂🔥
Its basically a continuation of my comment, good thinkin brother
I've enjoyed watching your process and admire how you have been trying so many different ideas to 3D print rocket parts! For a future video, I think it would be awesome if you 3D printed a piston engine like your steam engine, but powered by some sort of combustible fuel!
MakerJ101 at least I think that’s his name has a series where he builds one without a machine shop
for the pulsing rocket I think you were achieving too high of a pressure, thus it spiked, turned into a detonation, pressure dropped and it repeated
2 ideas to try;
First, I think you'll get more power if you add some sugar into this rocket-resin. Resin is a long chain molecule with its set, so it will burn slower than something like sugar. This will help you get a faster, hotter burn, without compromising the printing of the resin much. And it wouldn't take much sugar (by %) to get a good amount of improvement.
Second, since your machining skills have improved, try a revisit of the Tesla Turbine! Maybe power it with some rocket resin, and see that baby go nuts!
Video idea: well, more of a project idea I suppose. I really like this idea of 3d printing propellant grains, this could seriously be a game changer for solids/hybrids since you can print some really interesting grain geometries. Maybe you could make a video on making a data acquisition system that measures your rocket motor chamber pressure and thrust. Then, you could do another video on designing a rocket motor test bed that is reusable and can withstand multiple firings. Then finish it off with a test series and comparison of different propellant grain geometries and fuels. Then bonus video: build a high powered rocket and launch it with your best 3d printed fuel.
P.s. if you want any advice on building rocket motors/engines feel free to reach out to me. I'm a rocket propulsion engineer by profession and would love to collaborate with you.
Keep up the great work!
Love it BMFW!!!
I love that, might be a good idea to run it outside
I haven't finished yet, but I saw you were using a sparkler to ignite it, for cored rocket engines to work good, they need to be ignited at the end of the core farthest from the nozzle
Ref 3:25 => A more useful (assuming one is interested from a design standpoint) description of a rocket nozzle would be to state that the nozzle has a smaller diameter than the *_equivalent_* core diameter of the solid fuel (called 'grain'). Then it would have to be further explained that fuel grains may be *_cored_* in various shapes, so that the word "equivalent" means their *_effective circular diameter_* as IF they were cored in a cylinder shape. However as most small amateur rocket fuel grains *_are_* cored in a cylinder shape, it's easily comparable to the nozzle throat diameter.
Make a electric skate board and also attach two small rockets for a short boost
NASA uses Aluminum powder and Ammonium perchlorate. Try out this mixture in a new printed rocket.
You could also try to use Titanium powder, or maybe something like Magnesium.
Try replacing iron oxide with magnesium powder... I used by the past 50% Potassium chlorate and 50% magnesium power... It is a fast as your cellulose
Video Idea : “Build a Functional Jetpack Using 3D-Printed Parts and try it out.”
I think you can actually make rocket fuel with nitrocelulose, but you might need a bulkier chamber, would love to see that as a video
Yes that's just what Integza needs, more pressure and a stronger chamber... BOOM... Goodbye integza
Nitrocellulose is way to agressive in terms of burn rate over pressure. The higher your camber pressure gets the easier it will be to achieve even more just making it explode again. It’s not a fuel, its a explosive. Don’t kill yourselfe with it. It’s all fun as long as you don’t have a real pressure vessel surrounding ist. Then it get extremely dangerous
@@multidiamanthunter All rocket fuels are explosives.
It would be awesome to see you build a small Reaction Control System to use on a model rocket!
Future Video idea: You could build some kind of water cooling system to cool the overheating nozzle.
AZB said this first
Idea for some of your older projects? Husky high performance blow gun with ultimate flow tip. Look this up. That tip can nearly double the output when air is blown through it. Maybe it can be used on some of you're previous projects to increase thrust. The higher the output, the stronger the thrust.
video Idea: catapult-based space launchers that fire cargo off a track, nasa researched that some years ago and there was a startup called SpinLaunch trying it
*Integza* , since you have a problem with your engines melting down, use liquid nitrogen as fuel in a rocket engine :D (idea)
now thats some good thinking.
You should put the 3D printed rocket fuel into a aluminum casing to hold the pressure so that it can build thrust just like they use in model rockets 🚀
CAN ANYONE PLEASE JUST GIVE THIS MAN A METAL 3D PRINTER O:
Video idea: I would like to see one of your engines on a plane or something similar! I love flying vehicles!
Hey, Integza you should try to make a fine powder of nitrocellulose and mix it along with the oxidizer and resin to get a good fuel that can have a high burn rate
Nitrocellulose does not need an oxidizer, it is self contained already. That's why it can used as gunpowder.
Thanks for the awesome videos.I watch TKOR and it was to see that you’re working together with rockets and I’d love to see more rocket videos!

Video Idea: You mentioned, the last time you did a Tesla turbine video, that you were interested in progressively improving the turbine tech. I love combining different ideas from multiple people and I think I found a cool idea for a video.
Tom Stanton made a magnetically-levitated, flywheel-powered, alternator. The idea was to create something that had near-zero friction, which would allow nearly 100% efficiency.
It occurred to me that if you replaced the flywheel with a Tesla turbine, placed the levitation magnets on more than 2 sides of the center axle (to hold it in place better), and surrounded the axle with the turbine casing; you might be able to create a Tesla turbine that can actually spin an alternator at ridiculous speeds.
I would like to see something cool be made with conductive filament in a future video !
Video Idea: Add a nozzle to an Estes rocket and compare it against a stock version to see how much of an effect a nozzle has practically
You could try making an ethyl-alcohol and water fuel based engine like the german V2 rocket. This could be used in a liquid propellant engine something that would feel like an early year achievement.
Excellent video. My suggestion for an upcoming video: Build a 3D printed flying person with rockets attached to his/her backpack. Optionally: add a remote control.
Video idea: 3D printed 2 stage rocket tested with different types of fuel. Like gun power , sugar rockets , or even some sort of liquid fuel. And for the test try and get a speed test on them or how high they can go.
Cool video! But... I am wondering if you can experiment with railguns or coilguns (Maybe a Walter Catapult?) for giving your rockets an extra boost when they are taking off.
lol, that might be out of his budget.
I wish I could create these high-quality rockets. I remember once when one of Integza's videos gave me the inspiration to make a rocket which burnt my leg and nearly, my house.
I recommend checking "tech ingredients" on UA-cam. There are a lot of rocketry videos explaining everything step by step safely
@@emil8519 all i have are plastic bottles matches lighters and foil
@@miguelalejandrog.datiles9809 well yeah same thing with me. I recommended the channel if you're interested in rocketry and then decide if you actually want to make similar stuff. You obviously want to accure the products you need
Are you even trying if you're not nearly burning down your house?
Video idea: 3d print and launch a miniature v2 rocket.
I absolutely love your videos and just wanted to contribute my grain of salt to your testing: I've observed how you always use a scale to measure the thrust of your rockets, but I have the impression that you're not getting the accuracy you need and you can't read sudden peaks in power. I was thinking that you should maybe build an 'Integza official rocket testing stand' to try all of your rockets. I would start by having a look at strain gauges for mass measurement (like the ones that your scale has), or maybe some kind of rail where you can attach precise weights and compare designs.
After that, you could maybe make a special competition video, where you go back through your past designs and make some kind of ranking from best to worst (including a "best explosions" montage). I think a video like that would be awesome for new people to discover your channel.
Anyway, keep up the good work as always and don't hesitate contacting me if you need some info or ideas on the test stand (I'm an electrical engineer and I've build something similar in the past ;)
I bet a strain gauge -> Wheatstone bridge -> arduino ADC -> parallax DAQ Microsoft excel plugin would be perfect for this.
Great idea!

Try to achieve propulsion using ionization of the air, I suppose you could use some other gas too if you want but where’s the fun in not bonding with the atmosphere
Not going to happen.. sorry but the amount of thrust you get from it is so insignificant and so hard to get. Even if he was somehow able to make one, he probably wouldn't be able to measure the thrust because it's so minimal

Can you try turning the nitrocellulose into a powder and mixing it with the resin and oxidizer? Ping pong balls are another source of nitrocellulose if you don't want to keep making it. And nitrocellulose dissolves in acetone so maybe try mixing it in the resin to see if it works as well
I would like to see you revamp the idea of the ceramic printed nozzle. You already had it working, just add some glazing to make it more impervious.

Hi Integza,
I think for your next video, you should make and launch a rockoon and shot for space.
The project would use the rocket components you have been testing, a weather balloon and a small payload maybe a tomato, if you want to put one in orbit or a small satellite.
i am not sure on the numbers, if it would make it in to low earth orbit or not but the weather ball would cut the distance the rocket has to travel to achieve it massively.
this would also give you a project that uses the 3d printers for structure of the rocket, cradle and a small amount of electronics, Arduinos, raspberry pi. this would be good for igniter, gps, and other parts of the projects.
this would also give you a chance to use Altium designer for a custom pcb for the controls of the rockoon.
hope you enjoy the idea.
looking forward to the next video.
It seems like you may have an issue with cooling as well as *ahem* explosions... I suggest that you try some good old fashioned Liquid Oxygen cooling! Keeps things nice and cold... Or hot... One or the other, I can never remember... Regardless, more thrust!! :D
You should try to funnel the exhaust gases from a rocket motor and use the gas to turn a tesla turbine with a generator or a propeller on it :D. It might be inefficient but it would be intresting!
Hi Integza
Maybe you will try to make a turbine herona "The device consisted of a fire-heated boiler and a proper turbine in the form of a ball mounted on an axis. On its circumference there were two nozzles directed in opposite directions. the nozzles. The recoil forces of the same direction but the opposite direction, caused by the steam exiting the nozzles, generated thrust and set the ball in rotation. " Happy New Year
I think we've all seen that seen that too many times, even with liquid nitrogen. Also how often does he work with metal, because what you're talking about is insane to try to make even with someone who's good at metalworking and soldering
You should 3d print the whole rocket that way so that the entire thing burns away when it launches, and there is nothing left. It simplifies the recovery mechanism a great deal, if there is nothing left to recover.
Keep it simple. A rocket propelled RC car and try use F1 style down force to keep it grounded
Looks awesome! You should do a video on thrust vectoring like SpaceX does. Test your programming skillz!
Definitely, Thrust Vectoring is awesome.
video idea: You should try to make a 3d printed vacuum/flame-licker engine, it sucks a small flame in a cylinder and that flame heats up the air inside and pushes the piston back.
This is false, flame lickers are vacuum engines. They extract power from hot gasses cooling, not cool gasses heating. Look it up

You're making rather nice advancements with rockets! Since rockets occasionally touch on fluid dynamics, have you ever looked at supercavitation?
Video idea: You always use burning fuels to power your rockets, it would be cool to see you try powering a rocket with cold propelants like dry ice.
There's a reason propellants need to be hot - rockets convert thermal energy to kinetic energy. A cold propellant still has SOME thermal energy, but it's going to be extremely crappy

"If the value that comes out of the equation is greater than the speed of sound, congratulations, your rocket deserves a de laval nozzle" genius, love it! Very applause
Okay, I really need to win this so I can fix everything in my house. My best suggestion, looking more in-depth into the rocket itself. The differences in grain size, shape, and pressure etc and how best to make as efficient as possible.
Some rockets use the liquid fuel as a way to cool the rocket to keep it from melting. They pump it through tubes like a radiator but instead of a radiator its the nozzel. Maybe print something similar and try cooling the rocket with its own fuel?
Not in SRBs tho
Liquid fuel makes everything 9001% harder
It was used on the V-2 rockets to keep the steel from melting. They didn't have the advanced materials we do today.
Cardboard carbonise at 1000 C, so acts as a coolant as it gets consumed by the propellant burning. We use it as a liner in our reloadable rocket motors.
Estes and aerotech uses a bakalite plastic as a liner, this is an organic plastic that has been around for hundreds of years. They also use it in cookware.
What if you pressed a thin-walled metal tube into the shape of a nozzle? You can 3D print pressing dies and they perform suprisingly well!
Video Idea: You should try to make a rocket with the reactions you have used and make it 100% 3d printable. Maybe use the cotton as the propellant but more controlled.
Nikola would be proud! Keep at it! I'd love to see a 3D printed gyroscope, there are so many applications!

rocket exhaust to generate bubbles at the tip to greatly reduce drag.
I never thought resin 3D printing would be so explosive...
I would love to make a 3D printed engine that runs on some kind of fuel..
Could you make a actual rocket 3D printed that like in NASA with couple of engines. Just a small one. A verticle one.
great idea
I love it
You could make the grains out of 70/15/15 by mass AP/HTPB/Al, where AP is Ammonium perchlorate, HTPB is Hydroxyl-terminated polybutadiene and Al is aluminum. This mix is guaranteed to work impeccably and you could create the grains with 3D printed parts. Make sure though you don't do larger scale tests indoors, as if something goes wrong you won't be able to put out the fire and you could damage your belongings or even your health.
Make a LONG rocket? more fuel = more thrust right?
Not sure, but I think more length burns longer and more width burns stronger.
I love your vids and after watching this, I was thinking, is it possible to create a triple throat but one fuel chamber or three chambers, one throat? How inconsistent would it be? Also when you add the actual rocket to the motor in this video, how much faster would the thrust fade with the added weight?
These size rockets are too small for 3 nozzles, the size of the rocket would determine when 3 nozzles would become more efficent. Both costwise and fuel deliverywise.
Do you think that hydrogen balloons can double as fuel tanks for small rockets? Can you maybe try to build a weather-balloon-like device, that would take it to a high altitude, and when the lift of the lighter-than-air gas is no longer efficient, would compress the gas into a miniature engine to take the whole contraption even higher!
Video idea: Make an entirely 3d printed Squirrel Obstacle course ! Use your previously made 3d printed parts to make it even more interesting and ofc with a treat for them at the end! Good Luck!

*Integza* , since you have an issue with you engines melting down, why dont you liquid cool your engines just like the real ones.
(Idea)
Because regenerative cooling is only used on liquid-fueled rockets, they can't be used on SRB's. Also, a lot of the parts getting hot is the combustion chamber and regenerative cooling is generally only used on the nozzle. It is also extremely complicated, but it would be really cool to see Integza attempt this.
