- 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...
Not necessarily faster. It really depends on the part. Sometimes machining or other methods can be way faster.
The world is changing so fast, I'm just so happy to be a part of the journey!
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.
Ok. Soon enough ill be able to build a robot army. Much aha
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.
Thank you for posting this. I was confused when I read the part about 'building from the bottom up'. This clarified that, thank you.
this takes the paper jam to a whole new level
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.
immediately lost interest in the video because now all i want to know is how they make the stainless steel powder
Cryogenic Ball Milling
This technology is going to totally change the world!
THATS INCREDIBLE!!! WOW THIS IS LIKE SCIENCE AND ART HAD A BABY!!!!
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.
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.
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."
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.
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 is old 3D metal printing. Now we use powerful lasers that are way faster!
How its made. never gets old :)
we need to do this on a larger scale. Epic statues for every city.
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
4:52 BUUULLLSSSSHHHHIIIITTTTTTT!!!!!!!!
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.
3D metal printing so good result thanks for sharing new friend here from Bali watching see u
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.
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"
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.
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.
Sounds like a lot of nickle for the dime.
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.
No metal chip, no metal lost! I'love it!
This is the future sure wish I invested in it at its inception
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.
*joke about how the video was filmed with a potato*
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?!''.
Options for creating fancy doorknobs.
A) Hire a crew of specialist metalworkers, people with artistic sense, technical skill, and an understanding of materials science to manually craft doorknobs.
B) Hire a full CAD/CAM crew to set up and service robotized tools to machine doorknobs.
C) Hire one CAD person to draw the doorknob, then hire several minimum wagers to push a few buttons, pour powder in a box, and chuck the whole mess in a kiln.
Guess which looks best to your average MBA?
going to print myself a stainless steel bitch !
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 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.
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!
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.
WOW metal work just got a whole lot more easy.
Sweet layout on how to metal print.
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.
You guys should check out how far this technology has advanced. Shit's dope
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.
This is a great tool for manufacturing; prototypes can be made quickly and Chipley
Yes plastic 3d printers are common with different levels of sophistication. Most work much like a normal inkjet printer, printing layers of plastic until the object is complete. Much simpler to use than a metal printer. There is sometimes some excess material that needs to be trimmed but you can make whatever you like.
lets see you make something like this with that much detail perfect... and without any imperfections...
3D printing is gonna take over world a day!
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.
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. :)
Because the process would be able to produce pieces that are more complex than Cast iron molding.
The design process to machine is also digital so a person could design such a piece and then network it to the machine.
It can be a very fast process and it now used in aerospace were exact structures are required.
They're already starting to print a house with these machines ! :o
It's amazing how simple it is, really; we should have came up with this at least a decade ago.
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.
you can make almost literally ANYTHING with this and there are still 45 people who don't want this!!!!!!!!
Technology is the human's most important skill....
And this would be the new form of blacksmithing.
And if would think the methods and tools blacksmiths use these days are the same 500 years ago, then oh boy ur in for a surprise.
In this age, people tend to keep everything preserved in one form or another.
Just like archery, martial arts or any sort of obsolete thing from long ago, blacksmithing will be preserved and practiced as a hobby in the future
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!
"I Wouldn't steal a car, but i would download one if I could" We are really close to this days :)
The energy used to make these few pieces should probably be enough to supply electricity to a small city for a whole week :D
quite right, the reason to make stuff at home, even if it's more expensive, is that nobody sells the precise thing you want.
So far the composite materials offer the best options for such things. This metal process clearly has limitations , given the types of metals used here and why. If the finished item could have been in stainless steel we'd have been talking. I think a composite plastic lower or even magazines would be better choices than bronze or similar low melting point metals.
the one in the video probably costs close to $500,000 but you can expect to pay about $1500 for one for your own use.
My engineering teacher has one in his class room, its really cool.
The copper infusion really blew my mind, I would have never thought of doing something like that.
The most difficult part of making a mold is building the positive plug, which often consists of sculpting or machining wax. In this instance the positive plug is built virtually and with much greater detail, then printed. That's where the time savings comes in.
This is the WORLD WIDE web, dude.
There's always a market for things made the good old fashioned way. Don't worry, blacksmiths will NEVER disappear. But, if you need something made quickly and within 1 micron of a certain dimension, then you simply can't do that with a hammer and anvil. If I could have a sword made by this or a blacksmith with a hammer, I'd choose the blacksmith any day.
THE FUTURE IS HERE BABY!!!!!!!!!!!!!
3D printing can produce complexities that cannot be achieved in molds. 3D printing can produce very complex designs very fast from the digital design to the machine process.
What is going to happen at some point is that graphene is going to be added to the process and this will then produce parts like we have never seen before.
They will be hundreds of times stronger and exhibit properties like we have never seen like materials that can be conductors and insulators all in one.
Agreeing with you enigmahood; fact is that you can indeed print moving parts. This may use a different type of resin that would make a gunshot hard to contain, but is proof of concept and all you would have to do is engineer a denser, more structurally sound resin or refine the metal printing process to a method similar to this:
/watch?v=8aghzpO_UZE
The scanner really does scan fully around the object and takes into account all moving parts on the inside.
it's called cold weld, it's a special metal glue, using some kinda of electrolysis with epoxy "charge" to make pieces join one in other, there's a lot of brands, most famous are JB-WELD, PRO-WELD and ULTRAMETAL from Diamant Polymer...
i already used JB-Weld, and it glued perfectly a metal box for prototyping, and how i don't have a "contact welding machine", the result for me was more than i exprected!
Yes, a magazine, not the actual gun.
In order to 3D copy a fully functional AR-15 you have to scan each piece (or download a file that has it pre-scanned,) of the Ar-15. If you just scan a full AR-15 you'll get a piece of plastic that looks like an AR-15 but doesn't have anything that its supposed to on the inside
@BobMcCob really brings a new meaning to "You wouldn't download a car"
You could also have open source projects, people sharing their designs online for free. People just download the blueprint for something they like, and the 3d printer uses that to make it. :>
Better and faster process of metal 3D now
the real world applications possibilities are endless
Arbeitsplatzkiller! Job killer!
OH NO! "How things are made" videos...i believe i will consume 7 or 8 of these now.
I know exactly how good they are. And right now, unless you've got a machine more expensive than your house, you aren't printing anything electronic. At the moment, you can use a printer to make the non-electric parts of another printer, since nobody makes a cheap printer that's small enough to do microprocessors.
Also, unless you only need one or two of whatever you sell, you'll need to injection mold it. It's much faster.
Also, they only print one texture. You better not need anything soft.
that wood be pretty awesome
Yes you are. You replying to my comment was proof of this.
Doesn't matter that it's no cost effective OR slower... The point is that it's those things only right now, and as the process is refined, you'll see more and more 3D printing, to the point that it's so quick and cheap, that someone in the future will shake their head that we utilized "reductive machining" instead of "additive machining" at all. Remember that the first PC couldn't do anything near what the one you are looking at can do.
That was my same reply when my boyfriend told me about this in a conversation! "Like the Fifth Element! It's Leelu!"
Also, using a mould process you'd have to add extra material to make up for the imprecise nature of it (such as for draft angles etc), and then machine it off later, wasting material.
Consider the amount of time and energy CURRENTLY required to make a door-handle in a factory, then transport that to a warehouse, to a store, and finally to your home. Now imagine an alternate scenario where you have a 3D printer on your kitchen counter, hop on the printing app store, buy a $0.99 door-handle design and instantly print it in about five minutes. That's what it will be like in about 2-3 years. It literally already exists; they're currently bringing it to market.
it's called a 2 component glue and you can find it everywhere. Also, mythbusters demonstrated lifting a car with one drop of ordinary superglue if i remember correctly...
That would give a whole new meaning to "pirated products"
It makes hand-crafted things all the more valuable though.
If that be the case, at least we can relegate all those skills to the hands of the hobbyists. They can preserve those skills for the rest of humanity.
"You wouldn't download a car"
HELL YES I WOULD AND NOW I CAN
Wait, wouldnt the structure of crystal lattice be different from what you get with casting?
Here,here friend.
I hate it when science gets used for war,and it does pretty much all the time.
And then people quote science as the big bad wolf,but scientists are often the kindest souls,and do not want their inventions used for war,but somehow,it almost always happens..
I totally agree,that would ruin such a beautiful thing...
Yeah, every decade had its major, world changing invention.
The Home Computer in the 1980's. Cellphones in the 1990's. Broadband internet in the 2000's. Which technology it may be in this decade remains to be seen. 3D displays without eye glasses, Lithium sulfur batteries, who knows?
And in the 2020's it may be 3D printing.
You are correct, I did not think about the weight of the material.
Its weight generally keeps this from being a problem. The metal falls quite quickly.
PS With 3D CAD rendering of parts of guns we now have the ability to end the gun control debate, but for now since most affordable 3D printers use polymers, so far it's only good for the receiver and the magazine (which are the main parts being controlled anyways). Search for: 3D printed magazine
"Little" that's actually a pretty big piece for 3d printing standards
Now I understand how universe was created... ;-)
Two words: Mass Production.
