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


– My name is Jordan Myerberg, I’m a co-founder and CTO of Desktop Metal. And what we’ve done is developed and launched here
a 3D printer, for metal, that is safe and capable
of printing metal parts in your office. (synthesizer music) A lot of the state of
the art metal 3D printers use a powder bed, powder
bed fusion technique. Problem with powder bed is
that it’s messy, it’s unsafe and sometimes you have
to suit up completely, to operate with a machine
and with the powder. We wanted to get away from that. It’s expensive, it’s dangerous,
it’s not as accessible to everyone as say, FDM printing. So we took a very similar
approach to an extrusion technique to bind the powder into a
polymer matrix, extrude it, and then consolidate it in a furnace. Everybody knows FDM
printing, understands the techniques and limitations
that that process has and it’s very easy to operate. We’ve designed the software
from the ground up. We’ve started with a
slicer and the technique that’s used to print the
part, to support the part layer by layer, were telling the part, the operator the best
way to build that part. That is then transferred through
the cloud to the furnace. The furnace knows exactly
what has been printed and therefore knows the profile of which it needs to
center the blobject as. That creates a solid
part when you print it. Once you come take it out
of the furnace, the part can lift right off its supports. (mid tempo jazz music) So this is a step towards
direct manufacturing. We’re talking about a
prototyping process here where you can develop a functional part with the same materials
that you’re gonna use in mass production. And then we’ve launched
the production machine that you can then take
those same materials and launch into mass production. Printing process is
gonna be competitive with high volume manufacturing processes like metal injection molding for instance. So what you’re seeing
here, the studio system, is not scalable to mass production. We’re talking about one to
100 parts, so low volume. The Desktop Metal production
system is 100 times faster and it’s designed to
compete with the high volume manufacturing processes
that are commonly used in consumer electronics or in
the automotive industry. It’s designed to be a
mass production build box. So in other words,
printing hundreds of parts nested on top of one another. Not hundred of print beds,
but layers, so multiple layers with multiple parts on each layer, separated, on top of each other and then, when you take the parts
out of the printer, you put them into the furnace in the same kind of way, on layers, of kiln furniture and the
parts are consolidated. Very similar to the way
that metal injection molding is done, with the same materials
as metal injection molding. So if you’re a customer and you want to become more
flexible in your designs, you wanna use that in your manufacturing. You don’t have to change your alloys, you don’t have to change your systems. You’re using 316 or 17 four stainless now, you can use that exact same
material in our printers.

  1. 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?

  2. 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.

  3. 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?

  4. 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.

  5. Good video but quite one sided with scaremongering about 'wearing suits' and lie by omission (e.g. says nothing about strength).

  6. 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.

  7. Endurance have create a new 8.5W+ laser… Infinite power: can engrave on a stainless steel, aluminum, copper, etc.

  8. 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

  9. 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.

  10. 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.

  11. 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?

  12. this is binder jet printing instead of fdm?
    it uses binder to bind the powder instead of polymer wire and melt it.

  13. 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

  14. 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 ?

  15. 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?

  16. i bet the product is have terrible tensile strength compared casting methods…. but for non critical/structural application, additive method for metal manufacturing is interesting
