[@EntropyValley]

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!

[@makennasmith1477]

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?!?!?

[@EntropyValley]

@@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!

Honestly, he probably shouldn't be burning anything inside his attic, but the ABS was really the thing that worried me 😬

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.

[@boksininkas_ltukaras5005]

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

"Sparkler" is the sparkly thing you put on birthday cake. love the video

[@KeithOlson]

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.

[@origenestudiossas]

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.

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.

[@TuxieBSOD]

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.

[@anthonyscaglione9183]

Melting the metal isnt terribly hard to do either, especially if you use something like aluminum which has a relatively low melting point

[@CTMKD]

I think he already tried, I don't know...

[@Davinator2662]

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

[@markfergerson2145]

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.

[@Davinator2662]

@@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

This is pretty interesting, you got yourself a new subscriber

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!

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.

[@mangomonad]

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

[@TylerM4936]

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.

[@fitzi]

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.

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.

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!

[@scar3xcr0]

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.

[@jameselliott9055]

Integza ~ awesome 👌

[@kleinebre]

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!

[@isaack2274]

They are just an excuse to burn things.

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!

[@ZDavidH]

Nice video, you have a new subscriber! Saludos desde España!

[@Mark6O9]

Thanks for getting recommend to me

[@ryanb6464]

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.

I think it is about time you start casting some of the parts

[@maybethistime6761]

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!
