- Gefertec is a German additive manufacturing firm which unveiled a new machine which builds fully dense metal parts by layering beads of fused metal not unlike MIG welding.
The parts can be finished using conventional machining to achieve a desired surface, holes, and tolerances.

My great grandfather fought in WW1. After the war he was pattern maker during WW2. He made the patterns for the Engines in B17s Bombers and P51s .After the war he worked for NASA where made parts for the Apollo space program. I wish he was still alive to see this technology he would have been captivated. The delight on his face when I bought my first apple computer and Epson inkjet printer he was fascinated and couldn't believe that 4 colors could print with such detail. He did mention in the 70s that one day they will be able to print metal parts. I guess he had the foresight back then that is reality now.
I remember a crafty old machinist who adapted a mig welder to his cnc machine. Wildest thing I ever saw him do was rebuild the port-bias area of one of our cylinder heads where we had gotten into the water jacket during a port and polish job.
Imagine a combination with a grinder that grinds after every several layers before new layers close access to created complicated cavities so you can obtain smooth surface of a complicated shape product.
theres one like that
This would be awesome for moderately large propellers for small ships. The current order time is often a month or more for a broken prop where a larger version of this could make one in a day or two.
it's like a FDM printer had an affair with a 3-axis CNC and a MIG welder... NEAT!
It's going to matter when you need to prints parts remotely on some base on demand in the middle of no where. Just remote print parts that get damaged in battle w/o requiring a fly in of new parts. Just fly in spools of material.
like on mars
Well done to the designer. Very clever well executed.
Definitely Worth Watching.
Thanks for Sharing.
That’s freaking awesome! You see how nice it looked after smoothing out?
Smoothing out? You mean machining to final size and shape??
@@ronoldenbeuving695 nah, they just throw it in a acetone vapor chamber for an hour and presto, perfect part.
I thought about building a machine like this once. The issue is that its often much slower to build up your part, then finish machine, instead of hogging it out of stock.Especially for parts that remain mostly solid.
Excellent for me its better than other methods
That's incredible!!
basically CNC MIG Welding, i love it.
That concept exists since at least 2013 when MTU made a proof of concept for ~1500 usd. This technology could actually become affordable once the first chinese companies start mass producing it. Exciting!
If you fill it the chamber full of argon make it air right are more heat it will flow better
True. I seen porosity in the part. Lots of it. There's plenty more below the surface. Full shielding gas would prevent this.
That's true...and we will spend less power to make
If it’s fully enclosed would creating a vacuum help? No gas at all? (I’m a welding n00b so could be way off)
@@AmnesiaPhotography It would create overheating issues without any air convection to cool things down
@@nczioox1116 So, first, isolate it for creating a vacuum, and later you fill it with Argon.
Whay pressure could be used?
High/low pressure can help with the process?
Dam
now I have to build one
How would this compare to casting for cost and time .
I admired this machine
Company that takes a welder and makes it work with a 3d printing type style machine ( like that used for plastic) and put the price under 1000 euro will be the first company to make billions.
Zekerias Varg......won’t be the first company to make billions. Many companies make billions
I'll add....they wont make billions...they will be stopped from selling it...after all...they 3d printed a working gun from a plastic printer remember? The media kicked and screamed people could make...actual...functional guns from PLA. Imagine the outcry using metal....
@@wadebrewer7212 wtf do you think cnc is then? lol
@@jsullivan05 computer numerically controlled? The same thing that runs your desktop deskjet printer. Runs a Haas....your fdm...laser cutting....plasma tables...pretty much any repeatable robotic process.
Not sure...please enlighten me....
@@wadebrewer7212 You can "print a gun" with a cnc machine, instead of an additive process, it's a subtractive process, and it's MUCH more accurate, give me a 3x6x6 chunk of aluminum and I can crank out an AR lower in about 25-30 minutes on my CNC machine, and I built it with a GRBL and steppers, drives, linear rails, and ball screws I bought from ebay for less than 400 bux total.
3D Print Metal, Hmmm This can also be used to make a Beyblade: D
beyblade beybade let it rip!!
cant wait to get my hands on one and print me an arsenal of guns.
VERY VERY GENIUS BRO
Amazing technology 👌
So how thick is the layer?
In space this could be a very useful. Instead of using bar stock in different shapes.
It seems like the problem with this method is that you get the limitations of both processes instead of the advantages of each. But still, there is a place for this tech. Very cool!
very cool, but that stuff must be torture for endmills
Even though there is not so much to cut away, what about the tempering? The heat affected zones were visible in the machined part, but it still looks more solid than lasered deposition.
Can't wait to make my metal bey-blade
Make sure to destroy those brats in the park, daring to challenge you with their miserable store bought beyblades ;9
@@LoboPreto lal
Multiaxis Arm/tentacle style welding robot would take a lot less material to manufacture than this kind of traditional "box", afterall with this process it's all about the parameters, when they are optimized it will give if not ready to use parts, almost ready to use, altough metal casting and pressing parts will most certainly be competitive in future applications too.
this will be a game-changer for repair as soon as more 3d parts start being used frequently and need repair.
As soon as these parts are proven to be as reliable or better than traditionally machined parts yes.
Awesome!
wouldn't this process cause significant warpage in the final part?
Wouldn't a 3d printed part then casted, create a more unified blank to machine?
Yes... for now.
Not for your hobbyist's benchtop, but an interesting technique for particular niches.
Guy in the beginning looks like a vampire...
He is! So what?
can't wait.. in 20-30 years these machines will cost $500
and than everyone prints his own gun^^
Can’t wait, in 20-30 years I won’t be living in America anymore.
“I can’t wait! Literally! I can’t wait 20-30 years because I’ll be dead.” Lmao! 🤣 😆 😂
Don't count on it.
More like 5-10 years
Cool stuff
I imagine that distortion would preclude precision parts.
Maybe include a small grinding head next to the welding head so you can grind a section right after welding 'hopefully' reducing warping
I'm sure they account for that by making the welded part bigger, then it can still be machined to the precise shape regardless of any warping from the welding stage
vehicle repairs and space colonization
Amazing
What is the scan rate?
Sorry guys I just dont see the point off the produce which then requires machining after. It's just nuts. You need to dramatically reduce the layer build size then I would have one
it would depend on the cost of the feed stock. it might enable building up parts of more exotic alloys, or combinations of alloys within the same part via material changes, that would be prohibitively expensive using any other process. Also, some parts may only require minimal machining, it really depends on the application.
That's brilliant. The money you'd save on cutting heads due to massive reduction in tooling time alone would pay for itself!
that's only for prototyping, not for mass production
These printed pieces does has the same resistance to stress like forged steel?
I assume no. Forging incudes hammering/ compression of the material altering its properties. This metal has only been melted. I also assume it can be treated and hardened afterwards to make it more durable.
Thing is, although many parts can be 3D printed, the method is not suitable for some components. Take turbine parts such as impellers, blades or where high torque loading is demanded for example. These parts will need to be forged/cast and then processed to help the grain flow in the metals work for best strength/durability, etc. Exciting technology though is 3D printing, will certainly change the world.
I see porosity. Using this process for metal will be limited.
I agree it is but he did say its not for high end high strength parts. Its perfect for low strength parts. I think its perfect use is repairing parts.We know a good welder can do it by hand. But a machine just left to do it under CAD. Perfect.
Yeah I thought I saw some holes too.. But hey, it all starts somewhere. As long as the tech isn't mature, there's still hope for better results.
@@NightRunner417 I'm sure they could flood a chamber with inert gas.
@@nonyerbidness475 If they're not already doing that then they deserve a good smack, lol. They should be doing Argon or Helium.
@@NightRunner417
Why not nitrogen? It is pretty inert and they can get it from the surrounding air with a compressor
I see huge potential in remanufacturing very expensive worn or damaged components! Just have the missing portions brought back into existence and then machine to original specifications....there are parts for Porsche transmissions just for one of many examples that are totally unavailable leaving the only option to throw away $20k transmissions NOT because it is not possible to repair but only because Porshe refuses to provide replacement parts! And the parts in question will never be in high enough demand for the aftermarket to come to the rescue hence after 15 model years old or so otherwise very nice and still highly desirable/valuable vehicles become worth hardly anything compared to the same car in good running condition....it is NUTS but processes like these could really save the day I am guessing?
Better to use a billet material for greatest strength. 3D printed sand molds would be second best for strength. This would have to much crystalized structure in the material, but still can see many advantages for some applications.
*too much
Resolution seems way too low for aerospace even after all that cnc
I wonder if I left one of these in my garage for a month it would print me a lambo 😕😎🤣
20T lambo?
This is only for making a new one, am I right ? Not rebuilding
What is the cost?
yah but how is the metal, mig welds are usually brittle. to me it seems better to cast
Cold spray could still out perform this process.
Cold spray is extremely cool. We have visited Spee3D and checked out their machine.
This process has all of the disadvantages of pure cnc machining and also of 3d printing. I'm not convinced the system complexity and likely strength/quality/consistency issues will be fully offset by the possible production speed or material cost benefits.
This system has a huge advantage in price of material, speed and strength of the product.
Can the machine print its self
And here is where it started.
Work on the resolution...could be a replacement for standard 3d printing!
they need to use much thinner wire for that which is not cheaply aviable as far as i know
no
@@marc_frank yes
@@hyperhektor7733 i meant wade brewer
there is sls for high quality and wide range of materials
this is is for large pieces to improve material use
@@marc_frank sure, but i still would try thinner wires
How much price in India
CNC MIG
You cannot weld in strenght, not going to work for that. Metal has to be formed and precipitated heat treated for max strength. You cannot do that in a welding process.
Please don't underestimate, that will improve by the time
Could spacex print starship with this?
Prototype everything!
Everybody Gangsta till this printer cost below $1000.
Doesn´t sound like it is worth it. You still have to machine it so you loose the complexity advantage which is what makes 3d printing useful at all. In addition you now need 2 5 axis machines instead of one and you are getting charged an extreme premium for what is basically a wire tig welder on a robotic arm.
One day we will be able to print carbon fiber
Hi Thicc, there are a few companies that can print carbon fiber-filled materials, like Markforged. Check out this article - www.engineering.com/3DPrinting/3DPrintingArticles/ArticleID/19055/3D-Printing-with-Carbon-Fiber-Tracing-the-Lifecycle-Thread.aspx
That’s already being done.
Thanks both of you i didn’t know we could already print carbon fiber
@@athiccmotorcycle5437 Dont expect any kind of performance similar to carbon fiber parts though. Its like normal plastic filament with small carbon fiber particles. Which kind of defeats the purpose of the long strong strands that carbon fiber is known for. Its more of a gimmick for the time being.
most likely guns will be made if this makes to market
Prolly more suited for prototyping parts, too time-consuming in a production line.
But this type of printing will never make in production line... Because it takes a hell lot of time
Call me when you start making connecting rod For Turbo LS engines
Probably want to keep that forged
Engine blocks! No more open deck bulls**t. Thanks Ford...
lol. you can now close your own deck... - well it is a thought, once we can add on to existing parts (really is is just like CNC hardfacing) no more "manufacturers constraints, or "unrepairable parts (though as others have noted, techniques such as centrifugal casting and forging have their advantageous properties, sometimes it is easier to throw the old part in the recycling pot and start again.)..
Smaller arc with less heat...think nano. Your making the machine too big. This technology on a micro scale would be amazing! The sintering process is better at the moment but in a few years this technology will exponentially surpass the sintering process. Sintered parts are week and fragile...
You're.
I think sintered parts are month or day, not week.
Metal bending
Using process similar to mig welding? Let's see, wire fed through gun with electrical arc melting end of wire into puddle on part!
So what, are we going to change the name to GMP(rint)W?
Can't wait to fire up my metal printer in the morning.
I want to build my own private jet and take my family for a holiday in Milan. Hell I would travel world first class baby !!!! Extra leg room and french champagne !!! Can you 3d print french champagne too ?
Damon Blade it will still be insanely expensive to print it. Materials are cheap
I imagine printing the caviar would be easy though.
its just a mig welder
Big shit!
This is really kind of .... stupid. Mig weld these parts, then they have to be machined after. Just cast or machine out of a block of material.
If you can't melt the shavings and recycle into a new block then it is a much more waste of time, tool, money if you are up to making huge complex shapes that requires relatively little material for its starting block size.
Btw like this you are able to create hollow objects with complex structure inside what You couldn't if You are just machining a block.
@@resetcoder you can make hollow complex objects with lost wax castings though, or lost PLA using a cheap consumer 3D printer to make the molds.
@@cluebin8398 I know about different techniques, this is also one in the video. Pretty sure there are numerous use cases. Casting metal is a completely different job than just planning it in a CAD program and then upload it to this machine, and then you have a prototype for relatively little effort.
Video should come with a seizure warning.
Welder 1 milion de dóllar rs 300 year investiment return 😆😆😆😆😆😆😆😆😆😆😆😆😆😆😆😆
This is no better than machining. The metal that gets cut away gets recycled so there is no waste in machining. This device is just redundant
The surface finish is no good. And the time to make part from start to finish blasphemy.
Please don't underestimate, that will improve by the time
While additive manufacturing will continue to improve IMO the idea that it will completely replace conventional machining is at this time far fetched. For large volume production such as power train components for the automotive industry even with the continued improvements offered by both AM and casting processes items such as blocks, crankshafts, rods etc will continue to require finishing processes.
In reality additive manufacturing has been around for melennia. Think of jewelry built up from multiple pieces.. zits not what we think of as AM but it is really
those end results look terrrrrrrrrrrrible. even after machining!
But try to compare it to an iron CASTING .. then it looks a bit better
@@MikeBaxterABC does it? because castings are how a lot of them are made then machined. And they end up looking wayyyyyyyy better.
@@t_c5266 This true, I still like the 3DMP welder set up ... lets hope the second or third generation will be a bit nice finish! :) ... maybe combined with an onboard CNC machining system as well?
@@MikeBaxterABC yeah, first gen tech never is super good, i remember when i thought 3d printers were a stupid fad. but when this gets better, it'll probably be insanely good
not such a good product, it will still require a CNC to get to the finished part, also 4mm accuracy is just about useless in any industry and finally welded parts are always weaker than cast and machined parts, def a thumbs' down
