- In this video we will be describing trials of our second 3D printed light anti armor rocket launcher. We discuss what lessons we've learned, what went wrong and what went right, as well as the function of these rockets.
Print at 45° for non shear strength. (45° layer lines are not perpendicular with linear or 90° shear forces)
Awesome work !!!
Thank you! Cheers!
I had the thought while watching, instead of printing the nose cones in 100% infill. Print the nose cone w/ most of the cone solid(base layers) and the tip being hollow so when impacting the target the point crushes. I think this would create a harder impact and the solid base able to transfer the force.
This,
It would also reduce the chance of deflection/ricochet I would think.
These guys are amazing, so glad to see this out in the open! It so nice for a change
Excited to see how this turns out! Make sure to scrub the files well so MIB don't take it down, seen too many launcher builds get dissapeared over the past few months
We have a MK3 we'll be testing soon. Biggest challenge so far has been incrementally improving accuracy. Rockets arent bullets that's for sure! Gotta get those warheads on foreheads.
By "get dissapeared" you mean: End up being too hard for the folks who attempt it because it's literally rocket science?
stl when!?!?!? seriously though excellent work guys this is epic!
Can't stop the signal
Rofl. This isn't a public release...
@@BroughtToYouByDDean not yet. It still has flaws that must be designed out.
@@BroughtToYouByDDean So what?
@@DandSCreationsRelease it so the community can fix it. Stop gate keeping.
@@carboncollapse8435Awcy has their launcher designs. Several others as well! Check out the odd sea
arrange files for 3D printing, download?
I read that most anti armor weapons use short action rocket motors that burn stupidly fast (in milliseconds). Increasing the burn rate might help accuracy (and velocity), but plastic is not the ideal material.
Not ideal by any means, but massively more accessible than most, if not all, alternatives.
What I have seen in my testing is that plastic and resin polymers can benefit from faster burn rate. Resin cracks if exposed to mid intensity heat because it experiences thermal stress when cooling but survives with short duration high temps. ordinary plastic on the other hand produces a carbon barrier that protects the plastic from temperature. The reaction is so fast that most of the plastic doesn't melt but small parts act as a sacrificial layer.
Nothing about it is ideal. But we're not trying to create an Ideal anti-tank rocket, just an effective one.
And honestly drone-drop would be a FAR more effective delivery means. Were just exploring what is possible with consumer 3D printing. The rocket motor in the next round burns .400ms
ATF watching these at full mast
any chance you are accepting beta testers or have a odysee page for the 3d files?
Is the rocket motor still accelerating the projectile at the moment the projectile hits the plywood?
Maybe the still-accelerating-motor's forward force is strong enough to counteract the backwards force imparted on the detonator at the moment the projectile hits the plywood?
Have you tried shooting the projectile into something that won't break (big piece of metal)?
sweet guys! been following for a while now cant wait until this gets a public release.
also maybe you guys should start thinking about 3d printing molds for your pieces instead of 3d printing the parts themselves. you can then inject these molds with high tensile liquid polymer like some sort of silicone or resin.
Using these molds, you could probably make fiberglass/resin (or some other kind of fiber reenforced resin, such as kevlar, nylon, cotton, ect) parts, such as the launch tube. AT-4 uses a fiberglass launch tube.
Then you just have a normal anti tank weapon. We're not trying to produce a normal anti-tank weapon. We're trying to make a rapidly deployable design that can be sent and produced anywhere in the world, with next to no skill.
You guys must have plot armor or some really incriminating shit on the youtube execs, anyone else with this kind of content would be branded the antichrist by the almighty YT algorithm, well done
Use tungsten carbide ball bearings, I think those are the heaviest you can get
cool
What Rocketmotor do you use? and how does the motor in the rocket launcher ignite when there is only a methanol explosion?
This isn't the alcohol launcher. It's fully pyrotechnic. Black powder boost charge and apcp rocket motor
Out of curiosity, why do a boost motor system instead of just a straight solid motor all the way through? Wear and tear on the launcher?
To reduce the rocket exhaust hitting the user. But we will be removing the charge for now, and then reapplying it once we have an accurate and reliable munition.
@@DandSCreations gotcha. Thank you! Something like the early German panzerschreck blast shield might help!
The rocket looks like straight out of half life 2
Welcome to the watchlist, everyone
And this is why I’m not an engineer lol.
Neither are we! Lol
@@DandSCreations Lord help us all
@@HarshmanHills I do have a degree in aviation so I should be able to get this right haha.
Wernher van braun once said “Basic research is what I'm doing when I don't know what I am doing.”
@@moldybread6720 haha indeed. Horizontal flight rockets have a whole slew of considerations more intense than vertically flown rockets. We have learned alot and did finally achieve stability. Now we just have to refine the design. Which I've already made massive improvements to. It's on our Facebook page.
Had a question for you guys, I have a PSRL ( 40 mm) and they won’t sell any Inert ammunition to me (or to anybody without a government contract) ,any chance you guys can possibly make an inert rocket that can just shoot out of it ?
In time we plan to.
One project at a time though
@@DandSCreations anyway, I could support y’all?
Hellyeah!!!
Crikey!
What’s the name of his facebook page he was talking about at the end?
D&S Creations
Would you sell designs for the anti tank 🙂
To a manufacturer yes
@@DandSCreations ok what’s your email or contact
@@yalmadiable are you an FFL SOT?
@@DandSCreations I’m not from the US!
@@yalmadiable sorry I can't sell to non US entities.
Have you considered electroforming for your copper liners?
It would make it much easier for you or more importantly your end user to be able to actually print the shaped charge in it's entirety then using conductive paint and a simple copper sulfate solution. electroform a copper layer onto the plastic liner, once its thick enough it's ready to go once you fill the warhead.
Electroplating may actually be very helpful to reinforce some of the parts that take the most stress. A thin layer of copper then nickel will increase the strength of the part by a significant degree and would only add a few ounces of weigh depending on how much strength you need.
We're already printing the liners, and they actually work, extremely well I might add. 95% as effective as machined cones, however now we can test exotic geometries which would be prohibitively expensive to machine, and it only takes about an hour to print one.
@@DandSCreations What do you use to print with copper?
@@dinkelheit88 copper infused filament
*Makes rocket too sensitive*
*Drops Rocket*
*💣 💥*
And these are legal how?
Merica thats how!
Are you guys studying past rocket data? Why not just copy what works instead of starting form the ground up.
Because nobody has ever made a 3D printed plastic anti tank rocket before. So copying a design made of steel and aluminum won't work. We did manage to achieve stability, and our HE rounds are getting really close too now.. the next version the MK3 has all the fixes and I'm pretty positive well be blowing holes in steel targets soon.
Get an OMG for your SR.... or come join the dark side in V400 land
Huh?
Oh, I have a Bambu X1-C
@@DandSCreations Your video of your super racer, the default extruder is a clone and problematic. an OMGV2 extruder with a Capricorn Bowden tube will make the print quality and reliability of the Super Racer go way up. The V400 is FLSUN's super racer on steroids, built in Klipper, 400mm/s print time, Even more volume for builds. Got one of each if you need help printing for your tests.
@@oldskoolbmw it's been doing great so far. I'm just going to run it until something breaks, then I'll upgrade it. The Bambu has been a dream though.
Just make a potato gun launcher that launches rockets, no need for rocket boosters.
We did that already. Works great but it's not portable. Trying to make a useful effective anti armor weapon.
possibly a co2 cartage with a burst disk ?
All the problems have been designed out. The newest version is in production. The booster isn't needed with a 150 lb thrust motor on the new design.
I like how people can make cool some-what accurate rockets but if they have any kind of guidance they are illegal.
These would be illegal because they have shaped charge warheads. But they are produced on location with a licensed manufacturer.
