Evolution of 3D Printed Drone Munitions 

Yep!

The one and only!

It is indeed.

@@TheArmourersBench old mc donald had a drone, heya heya ho!

@@channel_lurker And on that drone, he put a bomb. Heya heya ho.

I have only seen them vog convertions on defcad do you know their real origin?

If you know any other source than defcad please hint 🙏🙏

Good man you are

@BigMakBattleBlog thanks mate! That's easy though, sitting at home safe and sound. You do the real work. We only play a minor part.

Not all farms are just in Ukraine (wink wink)

@@Maskedbrawler I know, but it is more interesting how to include them as an organic part of a units supply/maintance section. Especially when it comes to metal printing in the future like it is done on some warships today.

@@gilde915 Yeah, most of the units are being supplied from all over Europe by decentralized hobbyist groups. Bigmac included.

@@gilde915 Somewhere in the back lines of defense sure, the closer you get the more difficult it is to preserve your equipment from constant artillery and drone attacks

@@Maskedbrawler Iam a former logistics guy, i watch those developments closely and they are fascinating. Iam thinking about small kits that can be delievered to the back of a line and the unit itself prints out the bulky part of the equipment, be it metal or plastic. Just think about how many different spare parts can be made on location and the relieve you put on a logistics train, with all the different sorts of equipment a military like UAF is using today. No need to ship it from lets say Poland just send them the file and they can do it themselves.

We were generally unhappy with 3D printed parts while I was in the military. Too fragile or brittle, even after heat treating. But, they did come in handy making replacement knobs and noncritical widgets.

Have you seen the 3d printed guns the used by people in Myanmar fighting the junta?

@@asicdathens I'm sure I could find it now lol

They'd probably say it was too delicate (the plastic cases) to permit the average joe throwing crates full on and off a truck.

3d printed casings. The explosives aren't printed, just the plastic shells.

Yep

Happliy recived

Because it's a bomb, not a rocket. Different principles at work.

​@@donwyoming1936 It's the same principle; spin stabilization is a passive method to provide better accuracy for an object in flight. Key difference being that the flight here is straight downward. As for why these aren't spin stabilized, it's probably because their "flight" duration is too short for it to stray too far off course.

Because fin and spin stabilization achieve the same purpose, and HEAT warheads need to be spin-compensated. The copper cone for a regular HEAT can be made through rudimentary means but a spin compensated cone needs to be pressed with complex dies.

@@ChucksSEADnDEAD Fins + a slight spin has the advantage that any flaw in the projectile shape (or center of mass) that would cause it to veer off course will instead cause it to move in a spiral, likely reducing the distance it travels off target. For low velocity projectiles such as these the spin wouldn't need to be significant - less than a hundred RPM maybe. It's certainly plausible that the utility is negligible for this particular use case however.

There are also such designs. That requires fins to be longer, which adds printing time for example. I'm sure there are other reasons also for more simple fin design.

i think he lost a few more teeth since last time

Soldiers can just use empty casings

@@finnthunder6542 too large.

@@sjansen66 also too light no? too much air resistance for the volume

PLA melts at about 180*C, deforms at about 75*C.

Nope. Even hot glue affects the casing.

It's for keeping the shrapnel in place.

I saw both - mechanical impact fuses and electronic - simple with 2 contacts and complex with board with axelerometer that will explode on impact or could be detonated on command. Different variations exists - everything you can imagine - even proximity fuses that will detonate 1-2 meters above the ground

ballbearings?

Anything metal they can get their hands on.

might be ballbearings, small nails, nuts and bolts etc.

Ideally metal shot or pellets, same as a shot gun uses. using junk means you don't get a good pattern that's both dense and fly's fair enough.

Availability and portability. Molding facilities have to be built, a print farm can be anywhere.

Most of these parts are being manufactured all over Europe from outside of Ukraine. Injection molding is very expensive to set up and very rigid. The shells you see in this clip have all gone through at least 10 design iterations each.

Injection mould tooling costs hundreds of thousands of dollars, and requires huge industrial machines to use. These can be made anywhere with power, on a machine you can carry.

A lot of these parts have gone through multiple designs before being considered 'finished'. Usually a batch is sent, the soldiers use and test them and send feedback which is then used to adapt. If we had to make a mould every time we change an itty bitty part of it we'd be paying thousands out of pocket every time. All of this is done on a voluntary and free basis, the crowdfunding we occasionally do is to let the moulding run for a long batch and to help out soldiers with generators and other equipment they need aside from 3d printed parts

@@Maskedbrawler Thanks so much for the detailed explanation. Much appreciated. I saw videos of the drone team going to the front line hiding under bunkers to fly drones.... I know there are technologies that a person can fly drone even at 500km away. Not sure if it would help if this method can help. If anyone want to know more, pls reply here.

I think it's a case of different jobs different designs.

We could insert a copper cone into any desighn easy. And we do.

@@BigMakBattleBlog what about dropping some toe popper 1st on them then you have more time to come back with others? caltrop spikes ? rd flares think id have so many ideas over there . nerf screaming foot balls as duds to keep there nerves up

True enough. But that requires industrial equipment and all the associated infrastructure. These can be made literally anywhere with a domestic power supply, on a machine that weighs a few kilos and fits in the footwell of a car.

@@alun7006 But most of it is made nowhere near the front line. A lot of it comes from all over Europe. To mold this things or CNC them out of wood could accelerate the production rapidly. On the other hand: A lot of people have a 3D-Printer and can let it run at home while they do something else. It also depends on, if you have a shortage of casings, drones or explosives. If you do not have enough explosives, it does not matter, that the casing production is so slow.

Because 3d printers are pretty common and these can be made by anyone with 3d printer. Both in Ukraine and other countries. In material cost these are maybe around 1€/each.

To annoy you. Personally. They do it to annoy YOU. And 50 million other guys asking the same question over and over. They want you to get annoyed and be annoyed when you cut your nails so you cut them too far and it hurts. That's the only reason they do it that way. No other reason. Only that.

They have also been doing this

No.

Nope not happening, sorry that's all opsec for obvious reasons

If you want to help you can seek out Wildbees. You'll need to be vetted though.

@@Maskedbrawler How are STLs opsec when you post videos of them? It's a retarded thought. I can and will make my own it would just save me time.

Toy companies refuse to help, unless they are paid for manufacturing a mold and paid for the time and material to run their machines. For the PVC pipes, keep following Bigmac. ;)

@@sjansen66 No no it'll be wide Mac

Several of the parts being printed are injected molded but it costs money to run it and most of the printing is done on a voluntary basis and out of own pocket so fundraising takes a while

That presumes that 1) there is a factory in Ukraine that does that, 2) It was not yet bombed into oblivion by the Russians, and 3) they have the molds for those. With Russia bombing Ukraine's energy sector, those are more susceptible to power interruptions...

@@Maskedbrawler The Price per part would be cheaper and everyone that is 3d printing things would still be needed for a lot of things. But the parts that are tested and they need a big number of they should use injection molds instead.

@@theotherohlourdespadua1131 1. 2. You do not need a big factory, in principle you can put a machine into someone's garage and you do not need to mould the parts in Ukraine. 3. yes, you would need moulds of course. But it's simple to buy both machines and moulds on the open market. If you do not want to buy a machine, thousands of companies make injection moulded plastic parts just in Europe.

What's the point of a manufacturing method that outpaces drone construction? There's no advantage to stockpiling a million nade bodies while waiting for drone microchip shipments and for the build teams to solder them. 3d printing is perfect as each print farm has low investment cost and doesn't have the footprint of million dollar machinery which can be detected and targeted with cruise missile.

It's been tried and rejected.

pla is less hazardous to the environment compared to plastic bottles made from petg

@@Maskedbrawler To be honest, they have similar breakdown periods.

@@sjansen66 Theres nothing to talk bout when it comes to "breakdown" of this. - You be lucky if you find the metal shrapnell. Everything else has been atomized.. My thing is; why make thing to blow up when we have a lot of stuff we need to get rid off. The purpsoe was to get a standardized shape that behave in a known and predictable manner. Its to get it cheap and readily available everywhere. You can easily get that from bottles..

​@@martinwinther6013 You are severely underestimating the engineering behind those shells. There are that have quite advanced shrapnel patters, there are ones which have a HEAT charge and can punch through the top of a T72 and there are ones that are multipurpose. Try getting that into a cola bottle. By the way, Ukrainian drone operators started with cola bottles, even those 5L watercooler bottles for napalm-like charges and they are also dropping re-fused anti-tank mines. All have their own application.

They have actually been doing that.

They also 3D print things.

They try, we've seen more of their stuff tbh

A bot woukd say that.

@@ergosum5260 at this point i wouldn't be suprised

No drones won't be but I expect their uses will become further included into international treaties on the conduct of conflicts.

Serving member of the Ukrainian armed forces and paid as such.

And puts the vast majority of his pay back into gear/munitions for himself and his unit. Plus the thousands and thousands of £ of his own money he has spent to get there and stay there till he was taken in to the Ukranian army. He is there fighting for Ukraine as it is the right thing to do.

@@TheArmourersBench thank you for the clarification

@whatnowstinky Under the Hague Convention, particularly reflected in Article 47 of the Additional Protocol I to the Geneva Conventions (1977), paid volunteers fighting for or funding a foreign army may be classified as mercenaries if they meet specific criteria. This classification strips them of lawful combatant status, meaning they do not have the right to be treated as prisoners of war if captured. The International Convention against the Recruitment, Use, Financing, and Training of Mercenaries (1989) further criminalizes such activities, mandating that participating states prevent and punish the recruitment, financing, and use of mercenaries. Consequently, individuals engaging in these actions could face significant legal consequences under both international and domestic laws. And as you eloquently put it .....the money he is paid he puts back into the project.....that's the second part reply......
