That is gunna need a lot of finishing!
Wow! Impressive progress in the last few years
Thank you for video.
From algorithms perspective it is trivially-parallelizable problem:D
Technology is advancing rapidly, love it.!
Nice let's just hope the finish gets smoother
Six years ago this method was almost twenty years old.
It blew my mind back then, but it has never actually managed to make it widely to the market and there is a reason for that. Actually more than one.
So awesome!
Volume Production 3D Printing. So fast and Save cost~🤩
I still remember as a kid me and my brother used talk that someday they will make a 3D printer.
That is so cool!
Incredible!
love it!
I'll take my compressor wheels billet, thank you very much!
1mm too small BOV and that thing explodes and engine is a goner xD
great, epic, emotional and artistic😍
Several bits to know.
Laser sintering was one of the first 3d-print technology's. This is very old news.
Laser sintering is astoundingly energy hungry! For every watt in the laser beam, ten other watts had to die. Then there is equipment cooling...
Parts made by this process are going to be porous and less dense than cast metal or machined parts.
They will be far weaker, and being porous, they can wick up all sorts of liquids.
Internal corrosion is a thing with such parts. Nothing on the surface, rotting from the inside.
The surface of printed parts is rough, so you have need for metal forming/finishing tools.
The equipment is NOT something you will ever see on a desk-top; 440 volt service, connections to water/chiller, drainage.
And you can't buy one without a training certificate at the job site!
Yeah, this will solve everything!
Got any citation to the energy efficiency? Also from what Ive read porosity is something now like 00.5%. Your right though, these things are overhyped
No porosity. SLS is DMLS is SLM etc. They're all the same, each company needs one to call their own, and all of them have achieved nearly zero porosity. With the proper heat treatments, these parts are some of the best you can make regarding materials properties, a leg up on castings.
@@AbstergoView you don't need citations for this. It is more or less common knowledge that lasers are not super efficient. Ruby laser is around 10% efficient. CO2 laser is around 30% efficient. Most UV lasers are around 1% efficient.
I think some diode pumped fiber lasers can manage around 70% but since metals are reflective most of that energy will not be absorbed.
@@iridium9512
Laser efficiency is a moot point considering this processes a miniscule fraction of material compared to any substractive fabrication methode... Stop making points up guys ;)
@@IRNeuuub auctally, the entire method have problem, the leftover powder need to be replaced after a few time, laser takes a whole lot of energy, the strength of the parts that came out of it is questionable
But wait, there is more
It's auctally a relative health hazard to operate these, specially with the powder, which if got into any orifice can be a huge problem
That's amazing.
Super cool!
so you vacuum the metal dust manually in a one million worth machine. Cool.
Do u know cost of this machine
@@varunsharma-kx1iz nope
excelent!
DMG MORI... at its best
It seems like you could literally have a dozen lasers working at the same time.
I think what would be really effective is printers that can make highly detailed molds for casting metal objects that would normally be difficult to design, set up, cast etc.
The only thing you are going to see these used for is creating thin-walled parts that can't be easily machined on conventional machines.
They will be out of the price range for any kind of independent workers, hobbyists, and will only be profitable for small runs of highly complex geometries.
They are also slow.
That's just the nature of additive.
It is actually used to build moulds that need to be tested as it is cheaper to make it this way than make an actual mould. It's not ideal for mass manufacturing though. The machine itself costs about 500k and that's for the smallest in size (500mm table). You can certainly build things that cannot be built in any other way though. It's truly remarkable, but it does lack the surface quality and tolerance.
Incrível! Maravilhado!
WOW! Talk about the future of manufacturing. In-house stock building then right over to the machining center for manufacturing. Scrap a part? Make another blank. Unbelievable! And it's only the beginning.
Pablo Casiano
elijah mikle though you are buying specially prepared powders instead of e.g. cast or rolled blocks, sheets etc.
And this is really slow vs. molded, stamped, etc. parts. It's another manufacturing process, and will be the best choice for some (not all) applications.
There is a chance in the future that we can easily process raw material to special powder.
And improving additive machine into next level, every home have one, There is no physic transaction but design/cad. We can print entire vehicle with just single click.
this is so great discovery
very good Technic
Parts after production need to polishing?
Welcome to the future
I love it.
Very beautiful and nice
it's amazing to see this things. Can I use this video for my compilation? I will give you credits of course.
Awesome...
wow....awesome
Dammit I'm supposed to be studying for a law exam but somehow I now find myself watching videos on metal 3D printing...
amamzing!
this kind of machine is power hungry..
I'm surprise they need support for it being powder SLM, guess it'd be similar to SLS but perhaps the extra heat means it's needed... feels almost like a step backwards to have to use support material.
wow
Why are you everywhere where I'm going x3
2:32 They still would require a huge amount of polishing ....
That's quit interesting
Now I know where to look for super fine Al powder.
cloud seeding corp.
amazing
the future of metalworks and more...
Awesome
Okay, so how do you clean the lattice sections away if they are fused metals? When these were made from plastic, you could carve them out with a sharp pocket knife. I'm thinking you need something stronger than that working with metal. Also, is it still possible to heat treat these (essentially cast) parts? Or is this unnecessary?
The support structures aren’t needed but if used are cut off with power tools. Inside lattice fill doesnt exist because parts are solid
You can heat treat them also, you can do the usually polymer quenchent techniques.
You use carefully designed "teeth" to minimize the surface contact. Then you break them off with a hammer, chisel, etc.
Gah! The voids in those parts!
Genuinely curious, but what's new about this? The convenient programming? SLM has been around for more than 20 years, no?
Techmite there is nothing new here, but I do wonder why it was taking forever to laser sintering each layer,when they have galvonometer based projectors out there.
nothing they are just trying to slow the world down
We should of have this in our homes by now and way faster now.
But it would kill so many companies.
Get a can of powder metal, glass or plastic and make what you want.
you can build a toy for your kid or rise a army in the dark . But this all cut out the middle guy. and that is were the real money is at
blackgriffinxx it's always easy if you aren't the one having to do it. Enlighten us: what are the six easy steps to build one of these? Include the parts list, assembly drawings, wiring diagrams, mechanical drawings, software, laser maintenance guide, ...
Not really, SLS was, which is primarily plastics. Of course, SLS used metal balls in binders to make a part and then burnt off the binder which left a porous metal part that needed to be infiltrated later. Not so accurate or practical. SLM directly melts metal powder. While the process has been there for 12+ years, with the advent of more powerful lasers, higher temperature materials can be welded with higher densities and hence the excitement
good animation
После работы лазера обработать напильником!? Падстулом))))))))))))))))))
My dad took a course of these type of machines he works with ricoh and he's one of the first in europe that did this course the procces might be slow but have you seen any other 3d printers print like this and with curves and such but the good part is 1 opf these can produce 100's of them in some machines because you can stack all the products and most companies that use these kind of printers have serveral and create lot's of them so they can be printing a batch when 1 is finished and by the time the already made ones are sold the next 10 orso batches will be done aswell and the powder that is not used can just be re-used if you do a 50/50 mix so it's also good because it's re usable

20+ years old tech. Nothing new here...
We see the future
surface finish has left the chat
Does it need the inert gas? What would happen if there was vacuum instead?
my uni has one of these kind of machines
Omg.. u make that likes cookies...
Basic question. How to Remove the supports and the print from the Build plate?
Internal stresses
need to heat treatment
We are already on the future D:
do u have a desktop solutions
That's it? Wow i could built it by myself
Very surprise. But I have one question. If make the impeller by using the this process, it looks like a included the small hole on the blade. In my understand, the cavitation occur most likely on the small hole. Are there have any solution?
How the powerful laser . 😱😱😱😱
it seems that for some purposes the part might as well have been cast as the part still needs finishing by a machine tool (the finish is not that great) over all a grate concept(old aswell) but it could do with improving
What kind of tolerances do the parts come out?
Why is there a need for support structure under the blades? Doesnt the powder provide enough stability to hold the blade while sintering?
2:31 Looks like a relatively poor quality with lots of final touch-ups required with all that webbing and rough surfacing.
Compared to the amount of cleanup and machining post lost wax casting, this is pretty minimal really.
clearing those supports for hanging parts take time too
so lets say we made a rc engine, like 1/10s have, will it break?
its called Selective Laser Sintering SLS and i'm pretty sure it's been around since the 70s
Zach Brown This is called Selective Laser Melting and is different than SLS.
@@RandomNumber141 Not really, its just a higher energy density.
Steven m Yep. Which means the powder is melted instead of sintered. Two distinct things in the world of powder bed fusion
can we use this method for production of lens or reflectors? please someone reply.
Let's see that turbo wheel spin up to 20k RPM.
Selective laser sintering has been around roughly forever this is the next logical step.
cute toy.. but can it make it faster and cheaper?
Will it make its own parts when it breaks?
this employee is so brave to "act" without wearing Hepa mask..
its wow
Any non-destructive testing on these parts?
can it do an automotive cylinder head fit for machining? what type of price range?
How does this work? Is there no previous part in the powdered metal or is it just created entirely by the laser?
Nope, just powder melted layer by layer by the laser into the finished part.
ARE THE SURFACES UNIFORMLY SMOOTH AND IS THE TENSILE STRENGTH THE SAME AS IF IT HAD BEEN CAST FROM ONE PIECE OF MATERIAL?
A 3D printer but they use metal. Pretty cool
Usable for detailed part that doesnt need strength but precission
It'll be a hard time machining the support structure!
Which material powder is made of??
Machine for gifts so far.
these components still need post processing on the surface of parts, the surface of components is not smooth, if you want to get parts with smooth surface, you need to select the processing of investment cast for fabricating the engine blades.
What was the run time on those impellers?
How many kilojoules per square inch? How much electricity does it take to make a block 1“ x 1“?
Will they eventually be making entire car bodies? Engines?
А не слишком ли они пористые?
2:12 my fav part of the job!
I want one to print my rc car parts at home lol
Every 3D printing video it is turbine blade
what power has that laser?
speed it up to 100k rpm and collect it parts far far avay :)
Can you make the machined surface really smooth?
This is funny I came up with an idear like this for a story but i used iron sand and forge it in a small forge into stripes to build a building in the story. had a small robot pick up iron sand under water
Esta tecnología podría crear nave de una sola pieza
3D 프린터 도면을 주시면 제가 로켓을 제조해서 행성 화성 가보겠습니다.
are these using fiber lasers or could I feasibly just DIY something with a diode pumped laser with a dropping Z axis.
The laser only needs to move X-Y, the bed that holds the parts moves in Z to allow for new powder layers.
Ну и что ? Это же полуполуфабрикат ,все в раковинах , пилить и пилить еще до готового изделия. А как с термическим внутренними напряжениями,которые обязательно себя проявят при нагреве вылезут наружу в виде дефектов , возможно даже в трещинах ,а учитывая параметры работы блиска : обороты, температура и т.д. - это вообще опасно для агрегата такие вот сыромятины ставить в движок...
That powder would burn nicely in atmo....
