We are back to testing shaped charges once again! Steve, with D&S creations returned, to visit us to test out the latest project he developed: 3D printed shapes charges. Traditionally, the liners of explosive shaped charges are made from machined metal or pressed from mixtures of composite alloys. An explosive payload is then pressed behind the cone to make one seamless item. The idea of a 3D printed shape charge liner is a literal game changer as one can manufacture a very specific cone with desired geometry with simply a 3D printer and some metal wire.
Steve brought four prototype shaped charges to the table. A 3D printed cone with a plastic secondary layer, a Pyrex cone, a 3D printed copper cone, and a machine formed copper cone. We will test each one against a steel slug and our Gemini liquid explosive to determine overall performance. The main purpose is to see if a 3D printed cone would be comparable or better to machined metal cones. If it is, then we have a revolutionary new method to manufacture shape charges.
We will be following this up with putting these on 3D printed rocket propelled ordnance.

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!
Hello friend I did enjoy the video and I hope your work and videos go well
Hey ukra-nazi supporter, if RF tanks are in short supply, then why are the ukrops begging every country to send them more tanks and vehicles? 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? Looking forward to seeing you on the 2 way range.
ahh, IWA, so close (living in Austria) yet so far (not qualified to visit). You don't need a self-sponsored tag-along for one day? I know you don't need a german translator though.. :-)
got a link to that copper filament?
We the fans understand all good things take time, especially after all the unfortunate business and massive set back you guys suffered, good to see that you are getting back to business as usual as well your commitment to quality over quantity content.
Can't wait to see what you have planned.
Sorry for the delay! It's just non-stop issues here. The house we were planning on living in still isn't done. So we are still camping and trying to film at the ranch. Once the house is up, we can finally get back to some regularity.
I only come on TH-cam for watching particular content. Your channel is one of the few channels I actually look forward to viewing. Thank you for your efforts.
hey jake, you might want to hide your publically viewable subscribed channel to that cannabis channel. ATF probably wouldn't like that. Just watching out for ya.
@Nick G I debated on that. I actually co-own a federally legal hemp business. This was disclosed to the ATF. They only are concerned if we start trying to move meth or nose candy. Lol
Hopefully things start getting better for you lads in 2023.

"Plastic in the front, copper in the back"
Sounds like the explosive version of a mullet.
😅
That copper filament was really a game changer.
It sure was. I think it was best not to go ahead and heat sinter it. Unless done in a form or on a mandrel the printed item can sag or otherwise lose symmetry.
@@markfergerson2145 print with ceramic sinter the ceramic, and use that for support.
Is it ?
Press forming is one of the easier forming operations.
@@dwwolf4636 Can you do that on a 100-200 € machine which has a footprint of less than 0,5 m²?
It is absolutely amazing what the copper filament was able to do. Especially since it is cheap(Relatively speaking anyway.) and can be burped out of a cheapo printer in very short order, and it's really easy/inexpensive to tweak the design. That really is fantastic and super interesting.
I've got a theory that the layered nature of 3D prints did something to help even out the shock wave as it traveled through. I'd be very interested to see if/how adjusting print parameters such as layer height and nozzle width could influence the lensing profiles of otherwise identical cones.
If you have the tools, the last option is both a lot cheaper and faster then 3d-print. But it was cool that it worked.
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.
@@excitedbox5705 Alrighty then. You do you, bud.
@@excitedbox5705 $26 dollars US per Kilo, assuming the cone is 4in wide by 3-4in tall 2mm thick at 50g a shot, a reasonably tuned 3d printer can knock out 4 in about 30-45 min. 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.
I think the 3D printed copper one allows you to do weirder and more varied layer thickness on the liner. So I highly suggest in testing more experimental prints with the 3D printed copper liner.
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.
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.
I’ve seen EFP’s that have indents on them (like mk2 grenades) so the EFP turn to many small pieces of shrapnel instead of a big piece of shrapnel
In Minecraft of course 😂
@@GeorgeWashingtonLaserMusket Science Madness forum has a whole section dedicated to energetics, and a host of threads dedicated shaped charges.
@@GeorgeWashingtonLaserMusket While a lot of this and similarly imilarly military applicable stuff is heavily classified, there's more in the public domain than most people seem to think, especially in brick and mortar libraries. Remember the guy who got a visit from the FBI for writing a science fiction story about nuclear bombs in the 1940s; his fictional design (which was not what the government had built but would have worked) was based on what was in the public domain at the time.
@@evansoutdoors4022 you dont know what EFP means.
have you experimented with linear shaped charges?
We have! We are going to do a video on that comparing commercial liners and our own ones. Especially now that we have the lab up and running.
You guys should try to make some explosive reactive armor to complement the shaped charge series.
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.
Very interesting video. Educational while being entertaining isn't easy to pull off, but once again you guys succeeded in spectacular fashion. Loved the way each explosion sounded better and better. Thanks for the new video.
Be safe out there, and take it easy.
Best content creators on youtube!
Glad you appreciate the work!
@@OrdnanceLab this reminds me of the HEAT shells on tanks
So glad you guys are here and still on YT. Your content makes my day
Finally! Have been waiting for this video for forever.
Super cool. Love the fun, science based approach to your guys videos!
Wow! Amazing what you could 3d print. Great disclaimer about having all the correct papers on the wall. Keep up the great videos
Nice video. This one ought to really generate some calls to the RCMP.
I keep them on speed dial for when a new video posts.
Love the shape charge specials. Very cool MORE!
Very good proofs of concept .
Be interesting to see what kind of consistent performance is achievable under less than ideal manufacturing conditions .
whoops probably shouldn't have clicked the video with 'revolutionary' and 'shaped charges' in the title.
Dear SWAT: I will be waiting on my knees with my hands on my head and my dog is tied up 🥺
Great stuff thank for all you guys are doing 👍👍👍
Outstanding!!!!
Your fans understand and have nothing but best wishes for all of you! It seems that the more you can delay the charge wave front, the more power hits the surface. Full piece copper shaped cone.
Excellent footage guys!
Thanks my man!
It would be interesting to see these test EFP's scaled up to 84-90 mm, that size would put it in range of the AT 4 warhead. Imagine that with 3D printed cone and casing. Make the cone from copper and the charge sleeve from pla or some other polymer.
Try casting the copper liner. It'll be brittle, but hard to deform and might work well.
Copper is easily annealed. A few hours in an oven and it’d be soft again. I’d be curious to see of the softness effects the penetrating
You know it is gonna be good when the word 3D is in the title. Greetings from Spain. :D
Delightful. Thanks for sharing.
Gemini really is a great relaible consistent explosive, to my untrained eye at least, all those blasts were very similar in audio and appearance. Its a great explosive for this job as it almost removes a variable from the real sciencey stuff, like the way the penetrator develops according to shape and stand off required. Great work and, Fascinating stuff as always!!!
What exactly is Gemini? I can't find anything online, but from the results that do come up I assume it's another name for binary explosives in general?
Crazy stuff! Shaped charges are wild...
I'm always looking out for your videos. Keep making them and I'll keep watching
This is great, it could be used with a simple sling. Nice job.
Next objective : 3d print a plastic explosive lens and support structure to improve overall performance.
Love this channel, so great to see another vid drop!
Glad to see y’all back in the New Year! 🎉
I'm just glad to see you guys back.
Good to see you guys back!
Hmmm come a long way from the hell cannon lol
Great work guys!
Real cool !! 👍🏻👍🏻
I read everywhere that a RPG and other anti tank weapons can penetrate 900mm of steel or even more, i know it use more explosives and a bigger cone but it would be nice to see you test that. But awesome first vid of 2023.
Jake has the reactor up so we can now produce other explosives in 10 or more kilogram batches. So recreating an RPG with a clone correct warhead to test performance is now doable.
@@OrdnanceLab Would be so awesome to see. Love all ur vids. Nothing more beautiful than explosves.
This. Is. One. HECK of collab!
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.
Faster and easier to make a sand mold using a plastic 3d printed shape, then cast said shape.
According to the law of averages, you guys should be smooth sailing for at least the next 20 years.
3D printed + Explosive in the title. You guys are brave.
Damn. That part of "They're making rockets on my internet!" had me dieing.
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.
Oooh this is a very good topic to test.
I don't think that would work, the copper wire wouldn't deform evenly enough to form a concentric cone
@@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).
You are able to turn potential chemical energy into harmless fun , I guess it's called explosive magic.
This is very educational. I hope TH-cam doesn’t demonetize your channel.👌🏻 keep up the good work and stay safe👍🏻
Did Steve not get enough coffee before filming?
Sean drank all his energy drinks
@@OrdnanceLab 😆
Seems Steve is showing his human reaction to loss. My heart goes out to you, brother. It took me a year each to get over the loss of my mother and grandmother. They made me into the success I am today. I feel your loss. Time will help, but never heal one of life's greatest challenges! Kudos for all you guys do!!
@@qinarizonaful no, I'm just always muted. Dan lost his grandmother.
Think the best thing is this video is for "Educational purposes", As an engineer i love stuff like this and the possibilities it allows. As a human i worry about the other humans whos vision is slightly blurry haha.
Keep it up and development is the only way to take lives when needed and save lots of others.
You could use fluid 3D printing for castable burn out resin for vacuum casting. "VOGman" and "Clear Mind Jewellery" have examples of casted jewelry. Now if you would use that technique of vacuum casting. You could cast perfectly shaped copper shaped charge projectiles.
Greetings,
Jeff
the art of get on a watchlist as quick as possible
its so cool and so scary at the same time
Had the same idea. Cool to see it executed
Can we print it, yes we can.
It's literally impossible to say this line without using Bob the Builders voice.
wow right down the road from me guys NB. Great work gents, love it everytime
Your videos are always interesting and entertaining. Curious; how far into the ground the explosive pressure is forcing your test media?
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.
6:37 "Play it cool. It wasn't that much of a flinch...OH the camera was watching"
The president: you can't fight a tank with a ar15
The average 3d printing enthusiasts: and I took that personally.
yay! we're all on a list now!
Great stuff as ever! Would be interested to see how a cast copper cone would perform? Perhaps you could 3d print one, smooth it and make a silicone mold to make wax blanks to cast many? Keep up the good work y'all!
casting copper in a silicone mold? Not gonna happen. Silicone burns at a much lower temperature than even lead melts at.
@@arturjogi2667 no you cast the silicone mold, make wax blanks then use the lost wax casting method with some plaster around the wax blank. the hot metal burns out the wax and you're left with a metal piece in plaster. at no time does hot metal get near silicone. my mistake, i didn't explain all the steps very well. hope that helps! :)
How about using lead for a cone? Or even a segment testing different elements for the cones?
Titanium, osmium, maybe tungsten?
Might be fun
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.
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.
Wooohoooo new video!!!!!
Very cool testing on that! Copper Man Bunday and the material makes the difference! Excellent 👌 video
theres metal filled FDM filaments. i wonder how they would preform as a penetrator. or using say metal dust like the fine fine alu or iron dust you can buy sandwiched between two forms to act as a molded container to form the jet. ANYWAYS i love seeing any sort of EFP content! love to see more. id love to see a tandem charge head done with that 3d printed copper charge! two lenses would be insane!
90% copper filament was used for the 3rd liner.
Metal powders have been used as a liner. Mainly for bore hole related shaped charges. Dont eant solids to clog up that expensive drill attempt.
First charge made homeboy flinch lol
Don't forget to call the Mounties!
Jokes aside, this is pretty sick ngl. Maybe next time, we will see a homemade tandem shaped charge!
Reminds me of testing things on the demo range at Ft Hood. Got the range shut down twice and weight limits for the range reduced twice.
Very cool, I like the lab funnel. What's the angle on the machined one? 60 included? Looks about like a lathe center
3:28 Ear pro only works when it’s actually over your ears.
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.
I can’t wait to see what you guys have coming down the pipe this year.
Oh we have some fun projects planned!
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.
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.
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.
Wonderful video as always. Best of luck.
Yeah I’m likely never gonna do any of this, so I am glad I can see you do it. ;)
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.
Yo y’all dudes this is awesome. Thank you all so much you made my night. I appreciate y’all. Stay safe much love.
After a while you can hear if the shaped charge has penetrated just from the duller sound of the explosion. Presumably it's because you get better energy transfer or something.
"Quarter inch? Half an inch?" Sounds like a disappointing night
Man if y’all can make charges like this I can’t imagine how good the ones in actual weapons are
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..
I love your videos Man I love your content really really good happy y'all made this video keep going!
So a pressed copper cone wins. Just like the ones we have been using since the 1940's. Well done.
I used to work down the street from Raytheon. That place is like a fortress you can't get anywhere near that place without clearance. My mother's brother worked there in the early 80s. He developed guidance chips and other military weapons. He died from a strange form of cancer due to radiation exposure. HMMMMM 🧐
Homeboy flinched on 2nd charge too😂
awwww you literally have an ordnance lab out on the range as your supervisor haha. Doggo's are the best.
Very interesting. The fact that the D3 printed copper wasn't sintered and still performed so well is a surprise to me. It makes me wonder about specific hardnesses and alloys of copper. With the printer you can play with the shape, as others have mentioned. So many small details can be tweaked for maximum efficiency.
Those results absolutely blew me away (pun partially intended). I though there was *no way* that would ever work. Not only was I wrong, I was very wrong.
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. Similar to a plasma lance.
@@thomasschulz2167 makes sense. We used to make shape charges without any metal material. Lensing wasn't exactly the way we were trained to look at it.
"messed up with an f" is gonna be something i say on the daily hahaha
3:26 the way the right guys wears his helmet lmao
Make one out of tantalum. That has malleability similar to copper but a much higher melting point. 3D printed explosives is a very neat idea, as it could make precision shock wave shapes similar to machined charges but far safer to manufacture. 🤓
There’s no 3D printer tech for tantalum as far as I know, you can’t DMLS it. Maybe one of the binder print then sinter methods, but it’s higher temperature pressure required than other metals even inconel…
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.
Makes me reconsider getting rid of all the scrap copper I have.
I love the casual Borat references
You guys have way too much fun at work LOL
Have you guys ever used brass instead of copper for the liner? it's a alloy of copper but it might have different properties when lensing.
The 3d printed copper cone was my idea @Jake remember that?
awesome video guys!
Very nice! Can you use this technique to make a cutting charge? I always wanted to see how those work
Keep it up guys good work
Harder to tell but homeboy flinched on the 3rd charge too🤣🤣🤣🤣🤣
