Definitely cool. I’m a little concerned about durability and lifespan. I’d like to see some numbers and comparisons but it’s definitely an advance in tech.
This technology might be a game changer in space exploration. If we are able to create the base powder for these processes from raw materials without a foundry pressing and rolling billets off-world repair just became possible.
That is a great point. Even if you had a smaller version of this like something the size of a chair it could be game changing. Im curious how it would work in zero gravity or gravity equivalent to the moons gravity or mars gravity
I love this - 3D printing won't replace precision machining, but you just don't want to buy a huge solid block of some special alloy, have it shipped on a palette, only to mill 80-90% away again.
We got cold welding before GTA6. Seriously though, I hope you guys succeed. This could change how literally everything is manufactured. Thanks for making this.
I'm curious if any of the printed parts have been lab tested for micro fractures or strength and durability tested compared to machined parts? If they're able to meet or exceed the specs of a machined part. This will change the manufacturing industry. I'm also curious if they can adapt it to use aluminum, titanium and some other space age metals? What would really be cool is to make a small home or shop version that's affordable.
@@chiphill4856 6160 is only one type of aluminum and titanium and the other space aged materials were not mentioned. That's why I specifically listed those materials.
I doubt that titanium would be on the list due to its unique fusion properties. Maybe if they could do it with nitrogen in an air free environment it might work but oxidation prevents molten titanium from fusing to other molten titanium. That’s why you can’t traditionally weld it.
This is a cool but imprecise method. Definitely reduces the amount of material that will need to be machined away. I'd be interested to see how it compares to laser sintering in both precision and the resulting strength of materials. Seems like you would probably want to anneal the parts before machining.
Seen a concept of that around 20 years ago in a form of a conveyor belt and a nozzle that was placing the material - a lot simpler concept to what this is. Very nice!
How do the material metrics (tensile strength etc.) compare to traditional metal parts? Is there an advantage to this process compared with 3D printing/laser sintering.?
Apparently, for the limited materials they can handle, they're very similar in specs to normal cast parts edit: this is one of the 2 videos they link to at the end of this video: ua-cam.com/video/xWcgDoxXsJQ/v-deo.html It says it's "equivalent or better" than a cast part regarding properties such as the ones you mention
Now to get really cool. Seeing say 6 arms all working on the same part simultaneously would be awesome. Shouldn't be any reason you can't gang machine if you can nail the path planning software. Seriously, this is the kind of stuff we'll be doing in orbiting factories. A giant, multi-armed behemoth printing an entire ship structure in one piece with materials mined from metal rich asteroids. Add a bunch of mobile cnc machining centers to crawl around on the structure and finish the surface to size and spec.
What I dont understand is how they avoid oxidisation inside the part. When you look at the process in action, it all looks oxidized, then all of a sudden we see a table with nice refined parts. I can see on the parts that they have issues tho, what is their actual strength, and what needs to be done to further improve this process? You can especially see in the corners of the parts where they are unable to properly sand it, that there is still a bunch of oxidisation
I really doubt if that is practical. They have an earlier video of a smaller machine. The fine metal particles look like they go everywhere and into everything. The result would be similar - but more extreme - to what happens when you machine sintered metal parts. You end up with fine metal particles getting into the ways, ball screws, cable chains, tool changers, you name it. Then condensation rears its ugly head and you get dis-similar metal corrosion. Granted there are things you can do to control it, but it would likely always be less expensive just having a separate machining center.
I'm kind of betting that graphene parts can be made in the same way. Using Van der Waals forces. It would ensure that anything that isn't well bonded, and isn't graphene, gets knocked off.
@ I agree it ‘could’ cause issues, however, where I work it is common to weld high nickel alloys like inconell 625 & 685 to carbon steel. Even to 316 & 304 stainless. We also weld hastaloy 273 To the same alternative materials. We never have issues. Where there could be issues is in the application. Rocket engines and such. I think this could be applied to process control valves with hard service and cavitation issues. Rather than casting the body of the valve, print it like this but have the interior parts exposed to the process be strengthened with adding a high wear alloy. We have to send valves off to have welders weld a layer inside the entire valve body.
@ Sounds like a cool job! Welding is one thing, these printed parts are sintered, so I'm just not sure how that would work. Different alloys of the same base element may work as you stated. It would be cool to see if that would work.
What does the grain structure LOOK like? I assume a very HIGH heat treat temp IS required, along WITH finish machining. I dont see much if any advantage, your adding another VERY expensive HIGH maintenance machine to the process. Im not sure I would trust this process on very many applications.
To be fair, a lot of heat treatment requires high temps. That type of bronze heat treats at 800-1650°F, with stress relief at 600°F. You don't see the advantage of being able to print a part of any shape from powdered metal over machining a part from the appropriately sized bar stock? The amount of space you'd free up on a ship by eliminating the need for material stock and space for storing scrap and waste alone makes enough space for the machine. Not to mention advantages of only needing to machine the finish as opposed to the whole part? Chances are that most machine shops already have everything necessary for heat treating any parts that require it. But you go ahead and ho-hum about it like the guys who designed the thing haven't taken heat treatment and structural integrity or material properties into consideration.
@@bufordhighwater9872 As a CNC machinist for 25 years doing R&D in the Ortho field, on top of manufacturing processes involving CNC titanium additive PRINTING, near NET forgings, working hand and hand with EVERY design engineer in the industry a crossed the planet. I have seen BOTH SIDES of this. The only time I have seen an advantage is where it is impossible to machine SOME features in a monolithic billet of a very LARGE SIZE, and some very small like turbine blades that involve ports that cant be machined. Ho-hum indeed.
Hook it up to some mobile robotics and it could print the skyscrapers skeleton. Hauling powder into a densely populated area has got to be easier than what we are doing now. We can print out the hardware on different planets and have robots install the components after would allow for more different types of products to be manufactured.
Suprised the military isn't working on it. Being able to use 3d printers at forward bases would be dope. Start making a lot of the logistic vehicles, and machines, from parts they can 3d metal print. Could fit it on trailers that are towed. Would be cool to have an all in one, but feel like that is far off. (Meaning one that can print rubber, metal, plastic.) Someone else said perhaps graphene can be eventually used like this. That would be game changing.
Are 3d printed metals stronger and more superior to conventional metal processes or is it the same but more convenient with less material to take off a particular work pieces because its already in the ruff shape of the finished item and then all that needs to happen is to surface the item to finish the item and be ready to use wherever needed. If this new process makes the metal strong or the same as normal conventional processes then this is a brilliant technology that can advance productions and if this 3d printing technology isn't limited on size of the end product like how the 3d printer for concrete to build buildings that isn't size limited it can build on a massive scale. It's great when we find technologies that can actually do good things for humanity and not against humanity
That has got to be one of the coolest manufacturing advances.
No lasers
Additive manufacturing is out of my wheelhouse. I'm a non participating fan, this is awesome

That's pretty badass.
So it's active forging with static welding.
Pretty interesting idea

2012: " I love this but 3d printing won't replace metal forging "
It already has. 😂
Alrdy has buddy
Additive manufacturing should not be thought of as a replacement or competitor to machining, it should be thought of as a partner process.
We got cold welding before GTA6.

Can't wait to see what we have in 5-10years these printers are evolving so fast

He gave a list of materials, 6061 aluminum was in there

@@jamesbarber5410 I have seen machines at Virginia Tech that produce powdered metal titanium. It has to be sintered in heat after printing.
Isn't Titanium just spark and burn when super heated? I'm not sure. Just know the chips from milling it are flammable.

AMAZING time to be alive 😎
Its incredible 😮
Material scion es are the leading edge of human progress.
We need more material svion e college's

I have a need for this.
They should print a benchy. Their main application being marine/ship parts, a benchy would be really funny
Did not find any info on the Titanspee3d on your website, but it looks great! Looking forward to the titanium availability.
coolest ever, awesome
This is soooo cool
This looks like futures technology 😊
Would this function the same way in space/low gravity since it's a such a high flow system?
This should be able to produce multi-metal structures. Producing bi-matalic strips for welding dissimilar metals would be an obvious use.
Is there a laser in the middle of the stream? Or is that light from the impact heat?
could you use a different gas????
Thanks
could you get it to go to mach 7 ???
Thanks
If you're trying to go mach 7, you mine as well try going mach 9
This is a much needed tool for when we travel to other planets and star systems.

They probably use an inert gas as the propellant.
How many kilogramms per hour?
Will you be adding in-situ machining to this process? Seems like the next logical step. Every so many layers of deposition switch over to machining.
I really doubt if that is practical. They have an earlier video of a smaller machine. The fine metal particles look like they go everywhere and into everything. The result would be similar - but more extreme - to what happens when you machine sintered metal parts.

this sounds too good
This could also be used in conjunction with other metal printing to add different alloys at different parts of the process…
Multiple materials in the same part may cause issues. Bonding between materials and differences in thermal expansion come to mind.
@ I agree it ‘could’ cause issues, however, where I work it is common to weld high nickel alloys like inconell 625 & 685 to carbon steel. Even to 316 & 304 stainless. We also weld hastaloy 273

@@daveyshmavey A more complete explanation of this process would be great content. It's pretty innovative to use kinetic energy in this way.
It's like sand casting without a mold.
And with a very very large amount of heat
Now we are in the future, can this thing do gyroids?
0:41 very distracted by that piece... The heck is wrong with it?
Curved pieces look like they’ve been hand ground
