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.

[@rongarza9488]

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.

[@Shrek_Holmes]

so its not really the future of manufacturing

[@samsabruskongen]

@@Shrek_Holmes Not for mass production it isn't.

[@anon-means-anon]

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.

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! 😁😁🥰

[@freds4703]

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

[@rongarza9488]

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.

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.

[@jonanolakers1567]

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.

[@martylawson1638]

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.

[@EditOnRel3ase]

Yeah, it's also to help stabilize the structure and give it dimensional accuracy.

[@AJMansfield1]

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.

[@jonanolakers1567]

The more you know.

[@solarissv777]

@@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?

[@Hydrazine1000]

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.

[@sergioro8_125]

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).

[@jintsuubest9331]

[@odius5531]

Wondering how solid those prints are. Judging from the surface texture, I'm going to guess it may have micro air pockets inside.

[@trevorgoforth8963]

These printer produce parts that are 99.9% dense.

[@GraveUypo]

probably more solid than cast iron since that has huge bubbles in it most of the time

[@jintsuubest9331]

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.

[@Dick_Trady]

I think the exact opposite, casting is much more prone to defects. Layering fine powder is sure to be more effective in avoiding inclusions.

[@ThePolishedShooter]

Do a video about problems that sometimes happen in LPBF (parts brakeoff, recoater collision etc.)!

[@martylawson1638]

Didn't see any mounting bolts in those parts. Can the software add bosses for mounting the manifold to valves and structure?

[@markjones9481]

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.

316L is the weldable form of 316 stainless and if you weld something out of 316 the carbon bonds with the chromium to form chromium carbide robbing the product of its ability to resist corrosion so you effectively go from 18/10 stainless to a much lower corrosion resistant level of stainless steel. To make 316L in the initial steel making process they use calcium oxide instead of calcium carbonate to avoid adding any more carbon.

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.

[@Hydrazine1000]

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.

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.

[@Volt64bolt]

It’s mainly to help line stuff up, so that you don’t have islands that’s then have to connect accurately

[@jameslmorehead]

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.

[@faurana]

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.

[@timothystark5986]

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. kzbin.info/www/bejne/rpiaoaGom7WqhMU

[@trevorgoforth8963]

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.

[@sammyspaniel6054]

[@Caladain]

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?

[@trevorgoforth8963]

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.

[@Caladain]

@@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 :) )

[@lolglondar1345]

Very awsome work You been doing guys

[@mustjustbe]

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?

[@MRFano]

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 ?

[@trevorgoforth8963]

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.

[@salemyr]

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

That depends on the complexity of the part and if you can clean-sheet design the part for additive manufacturing. Just printing a part that was designed to originally be machined isn't likely to pay off, you'd leave too much benefit on the table. (I've seen a showcase where the printed part was more expensive by a factor of 10. But the improved wear life was also increased by at least that much. Net zero, right? It also reduced planned downtime tremendously and _THAT_ benefit made the 10x price hike an absolute no-brainer, less cost from downtime saved much more than the price of the part.)
