Honestly as a non machinist this sort of thing is like science fiction to me. Just incredible
Modded Crafting Table in Real Life.
Was blown away to learn within the next decade they will be able to 3d print body parts and organs unlike transplants from donors you won’t have to worry about your body rejecting it because it will be printed using your own cells harvested in a large Petre dish.
Its bsicly evwn more bad asbtos powder
It seems to be a very expensive process. This type of machinery is for special type of applications and not for a part that can be manufactured with mill, lathe or punch press. I could see this being used by NASA, or the military.
Remember when that guy thought he was building his own transformers but it was really the severed head of Megatron….
@@stevieg2755
Everyone knew what it meant!!
Referance to ?
@@thekraken1173its a reference to the transformers series not shore wich one
@@user-jk8vh3cw2x it was tf animated, i think
Modded Crafting Table in Real Life is getting more real.
This has been the future of manufacturing for 20 years ever since I wrote my thesis on it. The problem is that it is only really useful for bespoke, customer-individualized products. It doesn't scale like casting, extruding etc does.
That's the problem with both additive and subtractive. A plastics guy once told me he considered a kitty litter scooping fork "sexy", because it was just a single press of a hot die. Ah, if only everything in life were that simple.
so its not really the future of manufacturing
@@Shrek_Holmes Not for mass production it isn't.
That definitely prevents it from being useful for cheap mass production. The thing that makes it interesting to me is having the ability to make things that are not possible to make any other way regardless of price.
Do you have your thesis hosted publicly somewhere? It would be interesting to read it with 2023 eyes.
Well the LEAP fuel nozzle tips think this is pretty much scalable. 😅
I love watching the design modifications that are coming out these days. Coupled with the additive it is going to change the way we build things well into the future. Cool video bro!
Super solid video Trevor! Great job explaining somewhat complex things in an easy way to understand!👏👏
Awesome video Trevor! It’s super cool to watch that thing print when I walk by it AND it’s even cooler to see how this thing actually works!! All around awesomeness
Thanks dude!
@@trevorgoforth8963no problem bromosapien
I sure hope you have an action plan in case there’s an accident that releases a lot of the powder. I worked with many hazardous materials as a chemist and would recommend that all operations with the powders be done in an area with substantial airflow away from the equipment and operators then passing thru an appropriate HEPA filter.
Nah, Silicosis is totally fine
Yeah, @freds4703, my eyes opened wide when I saw the powder. Enclosures should be required. That building will eventually get the same treatment given to buildings that had asbestos. Still, one has to admire the risk takers.
Having worked in composite industry, big companies don't have good engineering controls or even fit you for respirators unless you take initiative. Its kinda fucked
@@xxxBradTxxx silicosis is specifically with silicates, won't happen with this. still bad for you, but won't cause silicosis.
Is the powder lethal if inhaled?
This looks awesome! I work in the dental milling sector in Germany. We mainly produce milling machines, but we also have a cooperation with a laser sintering manufacturer. This allows us to directly re-mill the 3D printed parts with our milling machines to have a perfect result.
Please also show the further processing! Removing supports, fixturing it, machining of the connecting points, etc. These as-printed parts still need some love and care before they can be put to use (or, if these are test prints/prototypes, at least that they _could_ be put to use.
Oh, and thanks for showing the internal teardrop cross section. Makes perfect sense to apply this trick, but I wasn't aware of it until now.
Where I am we have a SLM machine, and we remove the part of the build plate with a wire EDM machine! Then the build plate is sent to a machinist to be resurfaced and get reused. If the parts need futher processing, its the same as any cast part.
Edit: We do use 17-4PH stainless, which is way better steel (1000MPa yield) than 316 (less than 300 MPa yield).
@@sergioro8_125
Some question.
How do the internal channel get finished?
Like if you want to push fluid through those channel, you want surface as smooth as possible, no?
@@jintsuubest9331 what I've seen is that for parts that require a better surface finish get sanblasted. But electropolishing may be a pretty good idea
So now do you need to face or thread the ports so you can connect things to them? What application are these going into?
Do a video about problems that sometimes happen in LPBF (parts brakeoff, recoater collision etc.)!
Loved this video! Great explanation of the benefits of additive manufacturing!
PAPR is great but you need a safety suit also. Tyvek, lab coat, or a cover-all all provide skin exposure protection. They should also be fire resistant.
I love that you can produce more optimized complex geometric shapes. What processes would be involved in inspection. I can't see how you could pull out dimensional characteristics from this. Let alone successfully establish which NDT type would be acceptable to use for its validation.
This is incredible! Great job guys you have the coolest toys. 👊
Great video! Would we by any chance have the opportunity to see how those supports are removed?
I had no idea that you actually have to use supports for metal powder bed fusion. I have some experience in SLS printing, that uses polymers instead of metals, and it is able to print complex geometries completely without supports.
afik, the metal curls up if the overhangs get too steep. You then have a bad day if the metal curls enough to catch the powder spreading knife. So support structures are the lesser evil.
Yeah, it's also to help stabilize the structure and give it dimensional accuracy.
3D metal printers rely on thermal conduction through the printed part in order to cool the material down fast enough. Without a solid connection to the build plate, a free-floating part won't be able to cool off enough through the relatively insulating powder, leading to warping and a stuck powder spreader.
The more you know.
@@martylawson1638 I wonder if 3d printing can be done underwater, in this case heat would dissipate immediately, on the other hand, locally boiling water can mess up metal powder around it, maybe it can be done indeed were high pressure?
3D Printing is mind blowing... It's fascinating in an almost fictional way (though not fictional in modern era) like transparent aluminum.
316L is often used in high temp environments where carbon creeping in the metal is common and can cause crevice corrosion and cracking. It's why I use ultra thin stainless 316L for high performance turbo headers.
Would a 3D-printed 316L component have properties similar to a casting? I mainly care about how weldable it is.
As a guy that went into vehicle and equipment maintenance in 1968, and watching shows like Star Trek, seeing the way parts, etc, can be fabricated for any need when needed and NOT needing an inventory to pull from, I'm 100% sure with the raw materials, the 3D printers for off world parts will be HUGE! 😁😁🥰
What a fascinating video! Thank you Trevor!
I would like to see the final product after the CNC processing
i would like to see how they make that powder
THE FUTURE!!!!! My dad was explaining this to me. Also about how they were making the blades on some jet turbine blades which needed to be composites. Easier to do with the 3D print method.
That's really badass! I love this creative side of technology. 👍🏻👍🏻✌🏼
Would be interesting to see the process from start to final end product. Any chance of that happening? :)
How is the smoothness of the parts, especially on the inside? It seems it would be difficult to do any post processing work on some of these printed parts.
Damn that's some sweet equipment! 250k for the machine is not that crazy expensive, thought it would be more.
Wondering how solid those prints are. Judging from the surface texture, I'm going to guess it may have micro air pockets inside.
These printer produce parts that are 99.9% dense.
probably more solid than cast iron since that has huge bubbles in it most of the time
It is ongoing research topic.
There are post process technique to back fill the air pocket, but it is not at big as other issues.
Individual grain structure, grain boundary, surface imperfection, support placement, movement during printing, post processing, etc.
This is still relatively new, and we are still learning about it.
I think the exact opposite, casting is much more prone to defects. Layering fine powder is sure to be more effective in avoiding inclusions.
Is this the same material used making sintered parts? (Powder metal pressed into a shape)
Correct me if I'm wrong, but isn't the lower carbon content for better weldability? Which is kinda important in this use case? Corrosion resistance should be similar
Cool. Can you port these for anything? Jic/ORB etc. Is this for low pressure only as the tear drop shape creates flat surfaces that weaken or Crack the manifold? Can you machine these to fit valve carts? Are these generally for mobile applications?
That’s insane!! Nice job Trevor!! 💥💥💥
love the demo at the end. other than with plastic 3d printers, you will not easily pull off that part.
Will there be another video of these parts being finished? EDMed, workholding to face and thread the ports?
Incredible work !!!!
How would this method work for metal subject to repeated extremely high pressures, for example gun barrels and receivers?
much respect
when can we see the printed parts being put to use?
Great work Trevor.
what software did you all use from 4:10 - 5:15?
Didn't see any mounting bolts in those parts. Can the software add bosses for mounting the manifold to valves and structure?
About time you guys thought of this, should have bin done back in the 90s.
Incredible
Excellent !
Do they make a titanium powder as well?
You could build a Death Star with that type of engineering, it's clearly the future of the manufacturing
Awesome work Mr trevor BOOM 💥
Thanks Mohammed!
What about Oxygen getting in between the sintered pellets?
Interesting, but it seems slow and looks to be quite expensive. For specialized/custom parts only?
Maybe a dumb question but why does this type of 3D printing still need support?
Edit: Thanks a lot for the quick answers! I understand now.
It’s mainly to help line stuff up, so that you don’t have islands that’s then have to connect accurately
I've talked extensively with a major industrial 3D printer supplier (I've worked in the R&D field for over 13 years). Metal prints have a higher density after sintering, so it can sag into the un-sintered powder. When you expect micron accuracy, any sagging is unacceptable.
the granulate is a relatively good insulator compared to the sintered together metal (and baseplate) so without support you would have to wait extra long for the metal to cool down, additionally if it is entirely unsupported from even the side, it may very well shift when the next layer of granulate is layered over top.
hydraulic flow through non-straight pipes can also cause high mechanical stresses. these stresses are dependent on the flow rate of the fluid and the angle through which the fluid is changing directions. it has to do with the conservation of momentum. In underground water mains every time there is a change of direction you either need to use restrained joints or you pour a giant block of concrete called a thrust block to counteract these forces. th-cam.com/video/xg7pnrfPwNc/w-d-xo.html
Supports in this case are less about gravity and more about heat dissipation and ensuring you are anchored to the build plate so you don't get warpage from residual stress caused by the rapid heat input into the part.
Hey can you make aluminum car mouldings for the discontinued classic car market?
Just: Next Level Machining
Printing 😅
My son was working on these machines 😊
Amazing .we recently had a company in that can do this type of stuff showing us some parts .
Unreal what can be achieved
This process ,with this technology, can only be used for small production runs , I'd imagine.
Its used quite extensively within Aerospace and Formula 1, where typivcal levels of mass production isnt required.
SO, how does the inside of the channels look? is there a secondary process to remove the rough/porous surfaces on the inside top of the holes?
Yeh i think it likely that the gains are worth it over the worse surface in some applications especially if spade is an issue
Electrochemical polishing!
unnecessary to smoothen it when its out of stainless steel, except for maybe the outside so ppl can handle it without injuring themselves
Why wold powder bed printing need support structures?
Impressive.
I'm a Tool & Die Maker.. I didn't see things like this happening in the future when I was an Apprentice !!
How strong are metal 3d printed parts, is there some kind of post processing that can be done to combine the separate layers on a atomic level?
This is a huge technological advantage! As CNC could slowly fade away, just like blacksmithing, just something from the past.
Most Metallic sintered parts still require some degree of post machining on a CNC machine afterwards
Amazing technology! I’m sure that over time this process will become nothing but more affordable?
Awesome technology 👍
Maybe I missed it in a previous video on your 3d metal printing, but how do you clean the build plate? You wire EDM the part off, but that leaves bits on the plate. Do you chuck it and reface the plate? If so, is the build plate a consumable?
We usually put it in a lathe, mill, or surface grinder and face it until it cleans up all the way. The build plates have about 7mm of usable thickness before you need to get a new one. So in theory, if you are taking a .25mm clean up pass after every build, you can face the build plate 28 times before you need a new one.
@@trevorgoforth8963 Thanks for the reply! Are the build plates proprietary, or can you take raw stock, turn it to the right dimensions, and mount it to the printers mounting plate? (sorry if I'm getting the references wrong. There's near zero chance of me ever getting to play with one of these, so I'm living vicariously through your videos :) )
Обалденная технология,3D печать металлов это что то сверхъестественное.
Why are some of the ports just open while others seem to have support structure?
Very excellent video, BTW!
Because these engineers are way smarter than your dumb&ss will ever be.
This channel is in my top 5 all time favorites, but TH-cam doesnt show any new videos in my feeds. 😠
Very cool!
Bravo guys!
Hello! titans of cnc
Can you make a video on basics on 3d printing. I want to know about which slicer software or which should I use as a student what are types of 3d printing I mean there are lots of information on internet. Because I found you guys are very good in this. So I want to know basics from you
Hello! Thank you for your suggestion! We appreciate your continued support. 😊
Those machines are pretty incredible, by holy cow does it require a support system and a half.
What's the max pressure rating for the material?
Yes!
Trumpf (the 3D printer manufacturer) should design and manufacture a complete enclosed workflow to avoid contaminating the room or operators handling cylinders.
The enclosure should include all of the vacuuming, etc. The cycle time is increased too much, moving from device to device to suction the powder in respirators.
Build a safer and more efficient system..
Amazing.
I don't have any experience in anything with the word manufacturing in it.
I am very curious how the strength of this compares to something like a machined part from a solid chunk of metal?
is there a way to harden it, without deforming it?
is this manifold convoluted just for the sake of demonstrating what this whole process can do? This seems very useful for very specific, complicated designs, but nothing on a mass produced scale that casting can do already.
I'd love to see a strength test.
That is really cool, I just hope that part doesn't go anywhere that needs regular maintenance, lol.
What Unites the Particles - Glue??
Wish they had a class on this and more cnc.
This is crazy!
thats fucking amazing
How do you make metal powder?
Thanks i now realize it´s not a click on the button to get 3d metal prints out. I was checking seriously how to start bussiness with this gear. I will need some friends and funding,
how do you separate the part from the plate? also isn't there any leftover on the plate after the separation ? do you need to plane it afterward ?
Usually you cut the parts off an a wire edm or a saw. The build plates can be faced off an reused. They have 7mm of usable thickness so if you face .25mm off of the plate after each build you can use the same plate 28 times before you need a new one.
What psi is it rated too??
What are those manifolds for?
This could be useful for prototyping, but for mass production, injection molding is still much faster than 3D printing and repeatable.
But infinitely more polluting, moreover it has reached it's peak as of technology, while 3d printing is just at its beginning
So it's essentially SLS just with metal powder instead of plastic powder?
при хранении порошка в бочках нет опасности что порошок будет слёживаться? если в мешках, то можно ещё переворачивать
Have a look at Additive Industries’ MetalFab system, a completely autonomus system. Which means you dont have contact with the powder.
Where is the finished product?
Not for critical use without Hot Isostatic Pressing to remove voids. Have you looked at the purchase, install and operating cost of a HIP? Seems to be kind of expensive to produce and operate something that can create 15-45,000 PSI at 900-2,400F. And the max size seems to be about 2 and then some meters by three and then some meters.
It depends on the application requirements and on the printing method. If this is Selective Laser Melting (SLM), which this is, then you get past 99.5% density. As opposed to the earlier inferior method of Selective Laser Sintering (SLS), which could only achieve up to 95% density. And yes, SLS printing a metal part for a safety-critical application would probably need a HIP treatment. But not this part, this is fully leak-tight.
Progress Breathtaking
It's not the future, stuff like this has been around for a while, the problem with printed metal (pressed metal powder parts also fall into this with the same flaw) is that the powder will not always fully melt or bond to the entire part so then you have random structural issues leading to increased random defects
Not to mention, very likely it won't be NSD under X Ray, plus not sure how would it fair meeting tensile test , or intergranular corrosion test, and impact test , specially at -196 degree Celsius.
Guess in future it will, for now seems challenging...but for sure, looks lot less messy 😊
I'm suprised the vacuuming from the part step is done in an open environment outside a chamber
Why Nitrogen over Argon for the purge gas?
