Revolutionary 3D Printed Explosive Shaped Charges | Feat D&S Creations

[@OrdnanceLab]

Our first video of 2023 and we hope you enjoy it! We are busy getting the final details around the lab and range completed so we can get back to normal operations. We also have to get ready for SHOT show and IWA this year so we are doing our best to get filming done in between preparations for travel and also some testing we are doing for private contracts. We are getting back into shorts as YT supposedly fixed the algorithm for them. WE have a lot of fun ideas, too short for long videos, that we hope will do well in short video format. Stay tuned!

And if it's RF that is losing soldiers at a higher rate, why is it then that it is the ukrops that are having their 5th mobilization, whereas RF only had 1 partial mobilization?

not cheap, not available, not easy to produce compared to taking a piece of pipe section slicing it and rolling it flat and hammering/pressing it into a cone shape. 3D printing is slow, the filament is expensive, and you might not always have a 3D printer or electricity to print the cones.

For war time manufacture yeah that's shit, but for testing geometries for penetration ability … that's what rapid prototyping (i.e. 3d Printing) is built for. Once the shape has been finalized, print off a mold for casting in aluminum, and injection mold the plastic and copper suckers. Drives the cost through the floor and produces hundreds of thousands per hour at a proper factory, or hundreds a day using a home brew injection molder and any sufficient heat source. All that's left is explosives and delivery.

@@thomasschulz2167 I totally agree that 3D printing shouldn't be used for mass production but it's perfect for testing different geometries.

One of the cool things about the 3-D printed liner is that you could trivially tinker with different liner geometry including parabolas, conic sections, variable cross-sectional and radial thickness. Would be interesting to see what happens if you mounted a small tungsten pellet at the base or out front of the liner. I’m guessing there are all sorts of research papers available on liner development.

Edit, adding in 3D printed Wave Shapers like in the M380A1 HEAT round or a much more pronounced and variable-thickness cone should add more penetration.

Impressed that the copper liner was discussed. Most "shaped charge" you tube videos just kinda' leave the whole copper cone/penetrator out of the picture..

[@Mr.FraggOut]

You guys should try to make some explosive reactive armor to complement the shaped charge series.

[@alaric_]

One important thing to note: majority of the russian light IFV/APC used for troop transports use aluminium. The fronts use sloped armour but sides and the top extremely easy to penetrate with practically any shaped charge. Aluminium is light and easy to deform, it's mainly used against light shrapnel. Perhaps in the next tests, try the "least performing" charges against aluminium blocks and better performing with angled steel to see how they perform against them.

[@kaboom4679]

Very good proofs of concept . Be interesting to see what kind of consistent performance is achievable under less than ideal manufacturing conditions .

[@jakeaurod]

I'm curious what sort of effect you might get from winding copper wire around a conic form. Would some gauges be better than others? Would the pressure and heat of the explosion weld them into a liner or blow them apart? Would it help to bind them with glue or solder or some other sort of binder? Would a composite liner help? How about multiple layers of copper sheet wrapped around a cone and cut to fit? I just wonder what would be easier to make expediently if one did not have a 3D printer.

[@OrdnanceLab]

Oooh this is a very good topic to test.

[@acorgiwithacrown467]

I don't think that would work, the copper wire wouldn't deform evenly enough to form a concentric cone

[@mfree80286]

@@acorgiwithacrown467 I think it would work with a small penalty, just like the PLA/Cu print here did. 58mm pen versus 45mm pen may be down to 90% fill with homogenous 10% 'dead space' in the cone material and a little more loss due to overall density and maybe a need to change the cone angle due to that. PLA/CU also gives the opportunity to rapidly test iterations on cone angle, wall thickness and variations of wall thickness, maybe even formulaic solutions (lens curves on algebraic formulas to better take advantage of pressure/time curves for what's really an unenclosed explosive with these light printed containers).

What is the advantage of tantalum over copper? The liner doesn't melt anyway.

Tantalum has a much higher melting point, has a higher density and is very ductile. It can form a higher density and higher energy projectile. Copper is fine for most uses though tantalum will go through stuff that copper will not.

Fantastic video guys👍But think about using molybdenum as a liner material. There is a reason why the K-charge of General dynamics exists also with Mo-liner. There is a reason why companies like HC starck solution and Plansee manufacture Mo-liners. Not to mention that in 2007 ruag achieved penetration depths with molybdenum liners that were over 10 times deeper than the diameter of the charge.

[@tissuepaper9962]

Why go for 10x penetration when he can just print ten charges a lot cheaper? I know they don't add linearly, but it's not really relevant to my point. The entire purpose of this design is that it's extremely rapid and very cheap to produce compared to a more traditional shaped charge.

[@johnladuke6475]

That cost analysis is probably why _all_ shaped charges don't use molybdenum. Copper's not exactly cheap, but it's not quite so rare and expensive.

[@adelinyoungmark1929]

the interesting thing about copper cones is that not only can you 3d print them, but you can also make the electrolytically. basically you have your copper plating solution and a metal cone with some graphite paint (so the copper releases and still has good conductivity, silver paint works too) and you can make copper cones of any thickness depending on the time left in the plating solution.

For armor reference, most tanks in WWII and even modern day uses Rolled homogenous armor (RHA) for its steel armor (MBTs will have a mix of RHA, composites, heavy metals, and other materials in some areas that need the most protection like the front of the hull and the front of the turret, while the rest is typically just plane old RHA, though there could be composite screening, NERA, or ERA slapped on top to help defend against chemical and kinetic rounds in those areas.). I would say, the average side armor of a tank in WWII was between 30-50mm of RHA, while the front was typically thicker. The 3d printed copper would have gone through the side of many German tanks (All their light and medium tanks except Panther G and F), and the top of pretty much all of them. It could go through the top of pretty much every other tank in the war as well, and through the lower side plate behind the tracks of the Sherman. As for modern vehicles, this could easy go through a Bradley or BMP hull in many areas, and would do so against the BMP far easier as that has even less armor than the BMP, with most areas being less than 20mm thick, meaning it can be penned by .50 cal. For the Bradley, Im pretty sure it can go through the engine deck, the sides, and the rear, not sure about the front. The thing about MBTs though, is their armor is fairly classified, so maybe their top armor has some protective layer no one knows about that helps against these weaker shaped charge rounds, but based on what we know, most MBT's top armor is around 40mm thick for Nato, and slightly thicker for Russia and China I believe. I could be wrong.

[@PilotTed]

The shaped copper cone one with over 50mm of pen though, thats insane! FOr a home made shaped charge, that can go through most modern armor vehicles and tanks from the top, and many from the rear and side. Even some from the front. If you put a impact fuse and set em on a drone, this would be insane to drop onto an unsuspecting vehicle, and could mission kill it if you aimed for the engine or turret.

[@lukebaehr3851]

​@unexpectedspanishinquisiti3967 These guys actually did a video in the past explaining that using a drone to deploy explosives enters a whole other realm of the law (FAA), which is why they've never deployed munitions from drones...such a bummer; wish they could get creative with drones.

[@PilotTed]

@lukebaehr3851 Oh, I know, I wasn't saying they should do it. I'm just saying if someone does it against actusly tanks, these homemade shaped charges could prove very effective. They probably cost around $100 a piece, and it only takes maybe 2 on the engine deck to mission kill a modern MBT, which costs tens of millions of dollars.

[@lukebaehr3851]

@unexpectedspanishinquisiti3967 right! Far far cheaper than conventional munitions paid for by the taxpayers. What's the cost of a single replcement Javelin or Tow Missle? They are probably many 10s of thousands per unit, if not more. Not to mention the platform they're deployed from.

How about using lead for a cone? Or even a segment testing different elements for the cones? Titanium, osmium, maybe tungsten? Might be fun

[@acorgiwithacrown467]

I think with the more dense materials it would tend to shatter rather than form into a cone, tungsten in particular is not particularly malleable not to mention alot more expensive. Tantalum on the other hand sounds kind of ideal I doubt they haven't tested those materials before yet copper is still the go to for shaped charges.

[@johnladuke6475]

Hardness and density are likely less important than melting and evaporation points as far as determining whether a material behaves properly, shatters, or does some other crazy thing. Density would likely play a role in how much penetration is achieved, but it's possible that counterintuitively, less dense materials end up performing better as they convert to plasma. I'd bet that regardless of actual performance, the main reason copper is used as a standard rather than more exotic metals is due to cost of procurement and machining. Tungsten might perform 10% better, but for the cost of a tungsten liner you could maybe just triple the thickness of copper and get the same effect.

You can 3D print in tungsten (powder bed laser melting process). Some online 3D print services offer this material (beamler for instance). Probably fairly expensive. Would be interesting to see how it compares to copper...

[@EleaRevils]

That wont do you any good. the reason copper is used is because it reaches a certain acceleration where it becomes liquid or hydrodynamic and ''FLOWS'' through the armour. Now if you would use that tungsten as a solid penetrator, that would be effective. but then you are not making a anti armor rocket, but now you are designing a tankround. These charges have been around since 1886. And they still use copper today because it yields the best results. for a ligth caryable weapon.

[@pyalot]

@@EleaRevilsHeating and melting does not play a significant role in the physics of shaped charges. The effect creates a high velocity jet of material that acts as a projectile. Because it is a very small cross section (needle-like) moving very fast, it achieves a lot of penetration. I can imagine that shaping a correspondingly thinner solid tungsten cone would be very difficult, and that perhaps the thoughness of tungsten does not lend itself for the cone to easily form a clean jet. However, laser sintered tungsten powder is very different than solid tungsten. Much like the glass or copper infused 3d printer filament, it might „pulverize“ and yield to the explosive charge to form a clean jet. Shaped charges traditionally use copper because it is dense, inexpensive, easy to work into shape and malleable enough to yield to the explosive force. But back then laser sintering did not exist…

The fact that it wasn't sintered doesn't really matter. The base material can be what ever you want it to be, but to get the molten metal jet that does the penetrating you need to have enough copper mixed into the lens to do the job and designed in such a way that the jet will contact the smallest area on the armor allowing it to burn it's way through.

I’ve heard that magnesium is good but bronze cones or brass cones are just as good as pure annealed copper. You get significantly more penetration if the copper is annealed because it work hardens when it’s been formed into a cone and this slight bit of resistance can sap a little of the power of it turning inside out into a jet and also cracks can happen that let out hot gases which also effects penetration. It’s much better if you heat your copper up with a map gas torch first and dump it in some water to quench it. Not sure about printed cones though.

Very good "proof of concept", I'm surprised the layered plastic/copper liner (first sample) did so poorly and that the 3D-printed copper (third sample) did so well. A point of interest is that the smallest Panzerfaust (Klein) had roughly 3.5~4 times the explosive fill, so viewers expecting this tiny thing to do more than "scratch" tank armour was (perhaps) a bit too much.

Your videos are always interesting and entertaining. Curious; how far into the ground the explosive pressure is forcing your test media?

its so cool and so scary at the same time

I'd enjoy seeing a video on different thermites, particularly copper thermites as it reacts fast enough to be explosive when confined, and Thermate is the "military grade" variety of thermite. Thermites don't produce much gas so there's no possibility of them being anything but a generally weak low explosive, but they are still cool. I know other channels have already done extensive videos on thermites, but it's right up Oedanace Lab's alley. Codyslab had a video on copper thermite in a confined container but he had to take it down quite a while ago. Oh, and awesome video as always. Shaped charges still blow my mind.

Delightful. Thanks for sharing.

3D- printed copper liner: Check. 3D- printed rocket body: No problem. If you find a way to make an explosive filament, you could 3D- print the charge, as well.

3:26 the way the right guys wears his helmet lmao

[@napalmholocaust9093]

The Rpg7 has a focus ring made of plastic about an inch above the ignitor. You haven't mentioned it so I'll assume there isn't one. If its in other stuff you probably need it to be effective.

[@nehorlavazapalka]

It's completely f d up what they've done. They're using 3× less powerful explosive than they need and no wave shaper as you write. It's embarassing.

[@tmartin3151]

I can’t wait to see what you guys have coming down the pipe this year.

[@OrdnanceLab]

Oh we have some fun projects planned!

[@meanman6992]

Rockets! Where are the rockets!???

[@OrdnanceLab]

Next video. Jake is editing it.

[@dougmate2378]

wow right down the road from me guys NB. Great work gents, love it everytime

[@TheBic4]

What type of HE is used

[@NZMASTEROFGAME]

Wooohoooo new video!!!!!

[@acorgiwithacrown467]

Why not just make a 3d printed form to press copper plate into a copper cone? Coppers pretty soft, you could just hammer the form together.

[@deuscoromat742]

Better. Less complaining. Good start.

[@cgrosbeck]

What was the total weight on completed unit. One thing to consider is to vary the thickness and depth on the 3d printed coper cone, in order to get the proper liquefaction of the copper. Also there is the availability of 3d printed charge itself to increase the burn, think of solid rocket booster fuel shape.

[@akibi2352]

I LOVE YOU GUYS GREAT VIDEO

[@ArchonLicht]

What kind of filament did you use again? Copper what?

[@saddlepiggy]

Man if y’all can make charges like this I can’t imagine how good the ones in actual weapons are
