- How It's Made: 3D Metal Printing (Courtesy of Ex One)
With steel 3D printing, your part is created by binding together layers of steel powder. Specifically, after a layer of steel powder is spread across the base of a “build box”, a special print head moves back and forth over the layer, and deposits binding agent at specific points, as directed by a computer and your design file. Once the layer is finished and it has been dried via powerful overhead heaters, a new layer of powder is spread, and the process begins again. In this way, layer by layer, from the bottom up, your part is created.
Once the printing is done, the build box is placed in a curing oven and your part is sintered. The extra powder that was not bound, and is not part of your design, is then removed. At this point, your part is still very fragile. This so called “green state” will be the base of some of the design rules and limitations that follow below. Finally, via the use of a flute system, your design is infused with bronze, which replaces the binding agent. Your part is now solid metal, and after the flutes are manually removed, it is tumbled and polished to produce a smooth finish.

Are all of you, dear commenters, really that silly? This technology is not about making door handles! It is about forming any shape of any structure you could ever dream of. Very fine porous metal materials for example (impossible before), precise knuckle transplants etc...
I wish I had a 3D metal printer. The things I could make would be endless.
+electronicsNmore Batarangs and stuff. :D
learn how to build one yourself, DiY exist builds on YT they work with 100W lasers.
The world is changing so fast, I'm just so happy to be a part of the journey!
Thank you for posting this. I was confused when I read the part about 'building from the bottom up'. This clarified that, thank you.
Not necessarily faster. It really depends on the part. Sometimes machining or other methods can be way faster.
Ok. Soon enough ill be able to build a robot army. Much aha
this takes the paper jam to a whole new level
THATS INCREDIBLE!!! WOW THIS IS LIKE SCIENCE AND ART HAD A BABY!!!!
Heating one piece at 2000 degrees for 24 hrs is a fraction of the cost of conventional methods??
Ist's just a question of isolation. It does not have to consume much energy.
If I had a dollar for every pixel in this video I'd have 5 dollars
+toasteh Actually nearly 1 cent
If I had a dollar for every time I saw this same line, I’d be a millionaire.
This technology is going to totally change the world!
this is mind blowing imagine what we can do with 3d printers 20 years from now, it'll be whole new world, I think this invention is as big as the internet.
This is old 3D metal printing. Now we use powerful lasers that are way faster!
immediately lost interest in the video because now all i want to know is how they make the stainless steel powder
Cryogenic Ball Milling
we need to do this on a larger scale. Epic statues for every city.
My young friend @Leo Kao shared this post to show that, although he just recently got interested in the subject matter of 3D printing, he is already well oriented as to where the disruptive technology is heading for. Super glad that he will continue to keep abreast with 3D printing (additive manufacturing) both for work and for personal interest. The video clip, btw, provides a good overview and intro to people new to the topic of 3D printing. Worth checking out for sure.
This took several days and pretty expensive stuff to do a couple of stainless steel door handlers... and he said it was cheaper and faster... really?!?! a blacksmith can do this faster AND cheaper! I can see how this can be interesting but not as he said!
Not for long at the rate this technology advances.
*****
I would like to see advances in energy science to make energy cheaper and easier to get. Not 3D printing whose only purpose is to put more junk in the world. Sorry I am a technology skeptic...
Not many blacksmiths around these days (in developed nations). Perhaps you're thinking of a machinist. And it's doubtful that a skilled machinist or blacksmith would be able to produce complex objects like the ones in the video in less time, much less with the same level of consistency.
Calvin Huang
:-) A machinist only needs a mold. It's way faster... and cheaper. Furthermore, there is value in "lack of consistency" because it makes each piece unique and potentially more valuable overtime.
Teralek It also throws the ideas of mass production, interchangeable parts, and machined quality completely out the window. Also no mold is ever going to give you the same level of quality as what you just watched. Forget about the issue of having to build a new mold for each design.
Cheaper?! That look like a very expensive and time consuming way of making door handles compared to a cast.
Cheaper if you make an unique object is probably what they meant.
***** perhaps. ???
innovation is rarely cheap from the start. you know you're iphone was costful and super weak the first one?
Izio Shaba How is the iPhone innovation for anything? The Mobira (Nokia + Salora) mobile phones from the 80s were big and expensive. They created the NMT standard. That's a better analogy. In the late 80s Nokia was developing GSM which became standard - and we're using the 3rd and 4th generation of it currently.
how do you sleep at night?
i know what you're gonna say; "between two blond models in a hundred million dollar mansion"
How its made. never gets old :)
It's incredible, really. It IS simple and it's baffling that it hasn't been made more popular quite a bit earlier. But actually, now seems like the perfect time for this to get expo'd.
I'd love to be a part of making stuff like this more advanced, clean, sleek, and such. Maybe this is what I want to do for a living. Making this stuff more precise and help lift it off the ground and add to the force pushing it towards the sky.
why not just 3d print a mold for it?
Exactly. 3DTOPO has a video on lost PLA casting. Print up the part with PLA, create a mold with plaster of paris/sand/water, heat the mold to burn off the PLA and then cast it with molten metal. Amazing precision and detail - and much quicker than this method (hours versus days). This is almost identical to the lost wax technique used for centuries to achieve fine detail in jewelry.
what? no, just PRINT THE MOLD. just... make the mold instead of the object at the start
maksuree
and then pour liquid metal into what.... PLA?
TS100 is on the right track..
Laser Gnomes Actually printing the mold wouldn't be hard at all. It would use the same powder method as in this video. The powder would be sand, resin would be sprayed on by the printing head. Once it's done it is ready for casting. Resin bonded sand is one of the most videly used methods in metal casting.
Mazakala Think about the actual shape of the mold for the peice shown. Then think about how the printer would actually print this shape from the ground up. This is the actually one of the big problems with additive manufacturing, you can't print things in mid air. Secondary machining(uber complicated) could be used, but this kind've defeats the purpose.
this technology is obsolete now days. There are better ways of 3d printing with metals now with printers that use lasers to melt the metals into fusing layer by layer. It been done even with titanium.
Of course there are. My employer has replaced 5 generations of 3-D printers in the last 3 years, that's how fast the technology has evolved.
May i got your suggestion about several brand of 3D printing with metals even with titanium? i would like buy one of your suggestion.
Thanks a lot gigicaly :)
please reply to my email : lifemax_4ever@yahoo.co.id
WOW metal work just got a whole lot more easy.
3D metal printing so good result thanks for sharing new friend here from Bali watching see u
4:52 BUUULLLSSSSHHHHIIIITTTTTTT!!!!!!!!
Sounds like a lot of nickle for the dime.
Sweet layout on how to metal print.
Can anyone tell me more about these "jets on the print head"
What was shown was very fast and short, and I have never seen one of these in real life.
Thanks in advance
I want a 3D printer for food! I want it to print food for me, wonder how that would taste? :p
Trust me, no you don't!
nunya biznez So you know how it tastes?
***** I used to work in a restaurant many years ago. It's damned hard to keep that equipment clean. I have worked with 3-D printers and they are far more complex. Keeping one thoroughly clean to make such food safe to eat would be impossible. Any food you eat produced by one would be a bacteriological menagerie.
they have a vid on it on Tested youtube channel they look good and they people who tried it say its great
(Correct me if Im Wrong) I heard that some company that consumed Zcorp developed printing sugar so now you can print anything in sugar and see how it disolves in tea.
This is why that gun control is just a myth. People can already make a gun with a simple lathe if they want, but eventually metal printers will be as common as ink printers are today.
you can make a fully working gun out of a normal 3D printer
a myth? look up the definition lol
MrGareth66 no you can't you need like I dunno multiple degrees of discrete geometry if im not mistaken so yeah only the people with big knowledge on computers and math can make the guns work
Kennedy Del Rosario Most of these gun files are FREE and widely available on the web. Once you have those files, anyone can do this fairly easily. Thats why the govt is having a cow. Because it is really easy. The only thing slowing it down right now is the cost of initial setup. Nothing more. Its all plug and play. If you want, you can pick up AUTOCAD programs and tutorials for not much more and learn on your own.
STOP IT NOW JAKE!!! These printers that could print using metal costs millions of dollars, and waste lots of energy do you really believe that it will be cheaper soon? I think it will never be cheap as plastic printers.
Question: is it has strong has the real thing such as a printed nail vs a molded one?
Wait, wouldnt the structure of crystal lattice be different from what you get with casting?
It has been said by many respected names that surround the science world that, people of this time have lost or have been forbidden the technology that was known over 15,000 years ago that may have ended Atlantis. This could very well be how the Egyptians created all that we see and wonder about now.
Who the fuck has said that? The bum at the side of the street?
Mike B your site is as empty as your head
That could very well be, however it's far more likely that your education is lacking and your credulity is in overdrive.
that's how one person can make gun factory in his garage...
Must be a big garage...
And someone insanely rich! Metal 3D printers are crazy expensive.
***** i m just trying to say that ppl can make guns without any serialnumbers and also can make it as they want so it ll be hard for Ballistic Identification.cuz just a pistol with unknown records and info is a big problem for society especially in right hands...
***** pump actions aren't banned, its not thousands of dollars, you can get handguns and i would like to see the source for you saying that gun crime went up.
yes or they can buy a lathe and milling machine and do the same thing easier and quicker and cheaper and not need high tech equipment. These are good for making complex shapes of one of a kind items fairly quickly but not too good for mass production. This is an R&D tool. Of course, if you had one in your garage you certainly could make a gun but you would still have to machine certain parts of the gun, for example you would still need to precisely bore out the barrel.
I saw a faster method while visiting SpaceX. A layer of metal powder was laid down (titanium powder when I was watching) and then a laser melts the powder together where the object is. More layers are added until the part is done. Made some surprisingly strong yet porous metal parts.
THATS AWESOME !!!!
*joke about how the video was filmed with a potato*
going to print myself a stainless steel bitch !
So where can i find someone to make some parts for me? I have had a hard time getting them cut. But the machine could just make them. Thanks, brett
Applications are more ornamental than anything else with the current technology. We've "3D printed" working gearbox prototypes using Direct Metal Laser Sintering (DMLS) but...they cannot handle and significant loads. The issue is that most traditionally machined components are made of steel that is heat treated to obtain the required strength properties. This cannot be done YET with sintered metal powder technology.
Having said this...the "3D printing concept" itself has enormous potential.
That is by far the ugliest door handle I've ever seen hands down.
This shit sucks! all that money and maintenance of the machine that does half a day on one object +all that powder is simply too expensive.
Best thing is just learn to sculpture out of wax and do your own bronze casting instead of losing your possible artist skills to a machine that is part of a future were no sculpturing artists exist.
Sculpting requires two sets of skills: creative/design abilities and manufacturing/fabrication abilities. A 3D printer can do the manufacturing part, allowing artists to focus on the creative aspects that machines are incapable of. This doesn't mean there won't be any sculptors in the future. It just means many sculptors will likely do digital sculpting using programs like ZBrush, rather than using wax or clay.
Do you have any idea how much engergy and time it would take to do that if you want to have certain shapes? Besides that,you would a metalblock to start from.And wait:What happends with metal which has been "lasered away"?
why a lot of people are complaining about these handles, it was just an experiment to show you how things are work! well, they won't make a gun or a car... :/ still so much time so they can make huge and complicating things.. they can also make 3d hearts so they can be planted in the human body.. don't tell me that you can make a cheap one :/ because something like these are priceless!
This is the future sure wish I invested in it at its inception
Mankind will eventually adapt to it, like it did with the TV, cars, phones etc. Might seem scary now, as it does to me, but we will eventually adapt, and in no time you will be saying: ''God, how did we live without this all this time?!''.
You guys should check out how far this technology has advanced. Shit's dope
So could you take what is printed, and this could apply to any 3D printed object, and break it down and re-use the powder, in essence recycle it?
Does it work faster? a few days for one item compaired to a few days for 1000s of items
No metal chip, no metal lost! I'love it!
lets see you make something like this with that much detail perfect... and without any imperfections...
How does the bronze make its way to the object?
True, and another funny thing is the even the tablets and smartphones we have now, with size and capability compared, is so much better than a big desktop computer from just a decade ago.
Yep. So get started on learning to use 3d design software! There are heaps of free models to download (Think: chess pieces etc) but the best thing about this tech is, "Think it, design it, print it out."
is this really better than sand casting? Seems to take a long time just to make one object.
Ohhhh...now I get it. Thanks.
Awesome technology... Wish I had one.
makes sense to make one, and to make a mold from that and streamline it like that?
very nice, i was not aware. Was it developed by defense distributed?
This is a great tool for manufacturing; prototypes can be made quickly and Chipley
you can make almost literally ANYTHING with this and there are still 45 people who don't want this!!!!!!!!
So the final object is a kind of steel and bronze alloy ?
What kind of metal is the final product: bronze, stainless-steel or some other alloy?
This is crazy!
do they have a plastic 3d print capability yet? maybe with strong laser or something to bond the plastic
surely the final piece would be made up of a certain percentage of binder making it considerably weaker than a cast piece. Am i wrong or right, could someone please enlighten me
Very good! 👍
I strongly feel this can bring in a revolution in the medical sector to create best fir intricate joints and can be extended to back bone replacements as well :)
i am looking forward for that revolution that helps humanity.
how its made! i love this show
They're already starting to print a house with these machines ! :o
Arbeitsplatzkiller! Job killer!
Hi James. Fascinating new technology. real load strength, adequate shaft stress load capacity and tensile strength will be figured out in time. This paves the way for aircraft like we have never imagined before. Spaceships. Rockets. Huge metal printers to build aircraft! Oh my. Am I thinking correctly? Could those things be realized? Then there's the investment potential in a company like 3D systems, symbol DDD. Up 100% in the last year. Mind blowing. Exciting!
So you use CAD for outputting to that printer? Not Rhino?
I have a little tool & die background and can see how this concept will change the industry in certain areas, not all. This advancement shows the need to get an education and training if you want to exist in the future.
This is great for going right from a Mastercam file to having a prototype in your hand the next day. But for now, casting and stamping out parts is still way faster and more cost effective for mass production. To take most of a shift or longer to make just one part does not make sense to most manufacturers. But it does make sense to use this technology for making prototypes or a master mold which can than be used to make other molds or dies for mass production. My employer uses them to speed up the mold making process for use in lost wax manufacturing. Before, a model maker might take a week or longer to make one prototype or master mold or model. We used to have 20 model makers doing just that. Now we don't have model makers anymore. We have 3 3-D printers instead.
Any familiarity with the consumer CNCs like the shopbot? Sure looks tempting
LOVE LOVE LOVE!!!
What if we can buy stuff off the inter-tubes then it could print it right in are local printing stop. No shipping and handling .
I wanna know how they get the steel dust.
this thing is amazing.
3D printing is gonna take over world a day!
It's amazing how simple it is, really; we should have came up with this at least a decade ago.
that wood be pretty awesome
Where dose the binder go after its formed into metal, or did i miss that part.
When you use your CNC and cut away metal to form your object, what happens to the all the extra metal? I assume it's collected, recycled, reformed, reused, but you have to pay still for solid block each time you use the machine right? Either way, at present, I see a consumer version of a CNC or flowJet being far more feasible than this 3D metal printing..particularly with small pieces.
I don't know too much about 3d printing but..
Remember when computers used to be extremely large and sluggish and now they can be lifted by a finger.
Well could we possibly see a parallel to that within the world of 3d printing in the (near) future?
Just nice to think about how exponentially knowledge and technology grow. :)
awesome..but when are they going to get metal parts we can use for stress? like machine parts?
The energy used to make these few pieces should probably be enough to supply electricity to a small city for a whole week :D
so neat
I want to know which is best 3d machine and how much it cost for?
The copper infusion really blew my mind, I would have never thought of doing something like that.
that's so awesome
Very nice and interesting ...I hope one day they will shortify the process and make it user lesser big machines just like the process of computers started
great I really liked it
I believe it has capabilities that extend beyond simple caste work. The show here doesn't display it, but tools with moving parts can be constructed, which not only does the molding process, but the assembly as well.
Besides, the video is a couple years old. More effective 3D printing tools have been developed since then. Look at some more recent videos, it's surprising how accurate CAD designs can be constructed.
how do you make stainless steel powder?
in what other ways can metal 3d printing be used?
I'm confused about that part at the end. It can simulate "focus" (depth of field) or it produces an image in which you can focus with your eyes.
Which would require a hell of a lot more (depth) data.
Molds are great if you can afford getting the mold created. 3D Printing tackles that cost, as well as turnaround times. Originally called "rapid prototyping", 3D printing also allows you to build geometries unattainable via other means.
it's for flatrates with volume, am i right?
Unreal! Im wonder who designed the whole process-
