Desktop Metal’s 3D printer makes metal manufacturing less messy

1640 ratings | 232049 views
Metal fabrication with traditional processes like injection molding, can be noisy, create welding fumes and exhaust, and require the use of lots of chemicals by workers. Desktop Metal's new additive manufacturing method uses FDM techniques that are safer and easier to work with.

How does this get around the green part deformation during sintering as the polymer matrix (binder) burns off way before particle agglomeration begins? Also, what happens to the carbon that's left over during post processing?

So, basically, if you use a metal 3d printer from 3d systems or stratasys, and a 3d metal printer from Desktop Metal, to say print a 3cm by 3cm by 3cm stainless steel , or copper , cube - the cube created by a Desktop Metal 3d printer would weigh about 20 percent less , be less dense (mass/volume) than the metal cubes made by the other printers, right ? I say that because it sounds like he is suggesting that the inner metal lattice constructing the cube is akin to hollowed out swiss cheese - full of microscopic holes, as the binding polymer is removed - basically, the metal cube would look like a metal sponge on a microscopic level. No? Makes me wonder if the crown of gold which Archimedes had tested had been created by a Desktop Metal printer... So, why not "it is steel, but less dense than steel - good enough, right ?" metal parts ? Well, I would not wish to fly in an airplane built by such cheaper ( same volume, weigh less ) parts. Legislation is needed so that specially-marked defective parts can be traced back to the 3d printer and service bureau that create them. Water tasted better when it flowed through copper tubings, than plastic tubings, as it does now. Maybe thin copper skin tubing,, can be made, which will be cheap ?

not solid metal like laser sintered, sounds like epoxy mix with metal powder at a wild guess ?
Becky Russ (7 months ago)
when they can sinter metal powder similar the way the plastic 3d printer works through a fed tube. Using the bed as a ground and the powder as the hot

COST? and is this available in india
which company is that any information please

Looks grainy and cheap. I want a straight to mass production look not a prototype.
John theux (3 months ago)
The production system has a better resolution.
Ping Cheng Bon (1 year ago)
this is binder jet printing instead of fdm? it uses binder to bind the powder instead of polymer wire and melt it.
John theux (3 months ago)
The production system is binder jetting the studio system is between both in some way but it's considered as FDM.

Moore's law will bring the cost of these kinds of things down. I know this question has already run its course for some people but how do they intent to stop people from making weapons?
Brian G (1 year ago)
All hype. if you can't even address the strength of a finished part, it's obvious they are only pretty objects with no functionality.

Not all metal parts are structural my dude
SaltyBrains (1 year ago)
highly skeptical, nothing but talk and hot air unless they are willing in ANY of their demo videos to actually bake a part and show it's capabilities, strength, precision, and so on. blah blah blah blah blow me.
Mike Liu (1 year ago)
how much?
Elon Baartar (1 year ago)
so its NOT like a normal desk top 3d printer even though it was presented as "similar" because this thing when fresh out the printer is not complete, it needs a furnace to melt/heat treat? and yet the video was not showing the "furnace" unit openly as it did with the printer, its either intentionally hiding something or the video was not well thought-out
Matt Gough (6 months ago)
No it's pretty clear, infact you pretty much explained it in your comment, so it appears the video did explain it to you

but can it print glock 19 ?

Forged parts.... I don't think the chamber made out of this stuff is going to handle the 40,000 PSI of a 9mm +p+.
Kelly KitKat (1 month ago)
That definitely looks a lot safer than handling and touching metal powder. But not sure how safe that microwave oven is which can fuse metal.

Excellent work! Looks like a very handy process of manufacture.

HOW BIG OF A FUCKING PART CAN YOU PRINT???? why does no one say this???
LegendLength (1 year ago)
Good video but quite one sided with scaremongering about 'wearing suits' and lie by omission (e.g. says nothing about strength).
Funny Mario Bros (1 year ago)
have super quality plastic 3D printers finally reached $100 yet?
LegendLength (1 year ago)
From my casual watching on youtube the price point seems to be around $250 USD. Kind of talking out of my ass though.

Looks a lot like a normal FDM 3d printer with "metallic" filament....
John theux (3 months ago)
Real metallic filament because it's then sintered.
Daniel Peace (1 year ago)
This is expensive as fuck
james smith (1 year ago)
That to me sounds like it would be like pot metal .
Nathan Sharp (4 months ago)
theyre using a similar method in manufactering firing pins now. they use an injection mold process. I imagine the fillament is made of a similar feedstock.
yekcoh Kim (1 year ago)
polymer mix = increased porosity? Probably not a functional 3d print but good for prototyping.
John theux (3 months ago)
No, once the polymer is removed it's sintered and it shrink untile there is only metal.
no candy (1 year ago)
You'd be surprised. It's not going to replace a forged part, a lot of planetary gears and hypoid gears in tools, are made out of this same sintered metal material. Goes into the furnace, the fine porous structure kinda welds together.
DarkShadowsX5 (1 year ago)
prototyping and non high stress parts.
SHAMELESS US (1 year ago)
This looks really cool but something is off about making this printer.
ambrish sinha (1 year ago)
I would have liked if they have showed some microstructure of the final product. 'Printing' metal is less about 'time' and more about 'mechanical property' of the final product.

RompotMechanikos (1 year ago)
but how much does it cost?
John theux (3 months ago)
50 000 for the studio system. 500 000 to several millions for the production system.
itwasaaron (1 year ago)
Could this work for hard plastics and metal? Or is it exclusively for metal? Could the parts be strong enough for industrial use, like bus engine parts?
Thunderjunk Mcbuttram (1 year ago)
hmm i dont think engine part more like door hinges. Edit: thinking about it maybe not even that. I see this a a fancy form of cast metal
Cheikh Diaw (1 year ago)
itwasaaron l was asking myself the same question.
kong DaBomb (1 year ago)
All I'm seeing is a lot of demo reel stuff but I want to see some actual applications. Everytime I see videos about this printer it's all talking I want to see the parts being tested for strength. I want to see the actual curing process. But every time it's just stock footage. This makes me feel very skeptical.
John theux (3 months ago)
+Bondy The production system is binder jetting.
John theux (3 months ago)
Bondy (6 months ago)
I don't believe the production machine is FDM. Not if it's 100 times faster. The studio system is the FDM system. I think the production machine needs to be a powder based system.
ctbram0627 (7 months ago)
Yes with SLS powder printing machines that cost hundreds of thousands of dollars. This FDM process has very bad limitations. Anything with overhangs for instance would require supports and then the underside of the surface is terrible. This would be cheaper but I am concerned the limitations would make it impractical except in the most specialized applications.
Karkat Vantas (9 months ago)
James Dean doesn't mean that this particular product is up to snuff to the large, very expensive manufacturer grade 3d printers that they use. I'd still like for a real review of the product too.
James Barratt (1 year ago)
How strong are the parts. Like a gear cog could it be used on a motorcross bike with a chain around it doing wheelies with two heavy blokes on the bike? Or only make teasponns which forever break as you try to lift candy floss to your lips?
John theux (3 months ago)
Rick Kilhoffer (6 months ago)
DroneFragger that statement is false every gear in a GM and Ford heavy duty transfer case is powdered metal and the transmission carrier units are powdered metal so saying they are weak and fragile is false information.
DroneFragger (10 months ago)
You're burning out the binder, what you're essentially doing is turning a solid part made of a metal epoxy into a sintered part made of just metal. Sintered parts are hella weak and brittle.
Gary McKinnon (1 year ago)
".. candy floss to your lips" :)
no candy (1 year ago)
A lot of the planetary gears in modern hand drills, are made from sintered powdered metal. I don't think it's going to replace forged Parts anytime soon.
ingusmant (1 year ago)
The small version looks like it has too low resolution for actual use
John theux (3 months ago)
Yeah, the studio system is shit but the production system is a game changer.
MD. MUBARAK HOSSAIN (1 year ago)
Oh, awesome. What nozzle they have used ? Where could I get it? Please could anyone help me?

There's nothing "desktop" about that! lol the furnace thing is the size of a car.
John theux (3 months ago)
There is no powder for the studio system, no health issues.

there are electric kilns that can fit on a desktop. theres actually a vessel u can buy that's microwavable that somehow fires ceramics.

soundseeker63 it might fit on my desk... if I move a few computers around.
Mike Kojoori (1 year ago)
How does the strength of the end product differ from forged or C&C counterparts.
Sharothii Esmat (1 year ago)
Additional process might be required like stress relieving or tempering to get a good impact strength. The good thing about this process is that we can achieve a 97% theoretical density not achievable by competitive PM process.
RompotMechanikos (1 year ago)
+Kamijo Touma, have you ever tested the tensile strength of cast iron? it's pretty shit too.
Omega Supreme (1 year ago)
I'd imagine tensile strength is crap especially since well they never mentioned it once. That's an obvious tell.
Matt Miller (1 year ago)
CNC*** and the strength isn't bad because its sintered just under its melting point, so the metal molecules are fully bonded when you take it out of the oven.
AKlover (1 year ago)
Metal requires heat treatment and tempering specific to the part, how is that accomplished here???
eugenioLU91 (1 year ago)
you can simply make all those treatments after printing... like the other big volume manufacturers are doing
stalker (1 year ago)
I guess 3d pritner produces super fragile structure which then is put into oven.

argh100100 (1 year ago)
RompotMechanikos Simply not true at all. Depends on the type of cast iron. And I don't know what product you're making, but most cast iron is not shattered easily with a hammer. It can even be very ductile.

racingdave cheaper than the 900 Fortus MC by stratysus
LegendLength (1 year ago)
Quality will be nothing compared to a milled part
Matt Miller (1 year ago)
You gotta spend money to make money. These prices are on par with other metal working machines like CNC Mills. If you want it to cost 10k you're going to get chinese garbage that may or may not work each time you turn it on.
