The fact that I have an FDM 3D printer in my house is pretty much fiction at least if I would view it from pre2000s. Consumer plastic SLS printing (the one presented by CNC Titans is a metal SLS printer) is just around the corner and who knows, in couple of years/decades we'll have this metal SLS printing for the masses: ua-cam.com/video/hLqSaEiXzIU/v-deo.html
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.
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! 😁😁🥰
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.
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
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!
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.
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?
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.
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.
@@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?
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
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.
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.
Could you help a little with these? i have been thinking about buying the printer and having a dental milling unit, could u tell me something or where to search?
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.
It's felt like forever that this next millenium was gonna look anything like "the Future" since those from the 1950's saw us interstellar and austere in our perfection in 2025. Seeing there's zero waste this way, endlessly recyclable when a change-order/better design comes along, lower energy use, safer than casting/etc, and allows for absolute quality, we are finally looking like an intelligent race that doesn't need to pump out a gazillion units of crap quality and toxic materials that break easily and just fill random piles called landfills. It's about damn time.
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.
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.
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'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. ua-cam.com/video/xg7pnrfPwNc/v-deo.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.
Can 3D printing alloy and metal ever break through? What I learned in engineering school was not even Sinterkng or casting materials make due for high stress apllications. The crystalline structure will never be optimal no matter how much you try to heat treat it afterwards. 3D printing is basically spot welding, right!? The stress uneven heat transfer, different crystalline patterns amd material pockets are all an issue
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,
@@trevorgoforth8963 that’s fair enough hell if you want you can design it and I’ll print it and send it to you I only got FDM though not nearly as cool as you !!
future as to replace standard steel manufacturing processes? not a chance. supplement for cheaper parts, sure. steel (Fe + C) has so many different options for how to make it for different applications, its ridicules. so bonding small particles like 3d printer does it looks similar to sintering. where with pressure resulting in heat you weld particles together, but with 3d printer you probably weld particles together with laser. sintered material is usually hard but not ductile. and not to mention you working with 20%Cr in your material. what happens with Cr when you heat the particle? does it stay where it should? does it flow to the outer edge.. whats the moleculal stucture of particle before and after bonding etc etc.. so sure 3d printer has some application, but to replace every steel manufacturing process this is just a clickbait. correct me if im wrong.
It's amazing how when you laser etch a 2D image in a repeating sequence and when it's done you get a 3D intracit print ,with exact tolerances! This is awesome , star trek tech 😂😂 now imagine letting Ai use this NOT!!!😂😂
With this technology, you could basically print a whole gun. Heck, you could do a lot with this. Manufacture casings for exotic munitions, make custom barrels for rifles. This is a massive game-changer.
Metal 3D Printing is an addition to manufacturing methods and not a replacement for existing technologies. You only have to look at the production times on these machines to know that. Of course, metal 3D printing can produce geometry that cannot be made any other way, but cost is still very important in mass production. When a designer constructs a part, he must also take into account how this part can be manufactured cost-effectively. If he does not do this, he is a bad designer and should take up another profession.
While metal 3D printing can be used for protoyping of mass produced parts, more often than not they are used as the final parts in low volume production where the designer will take advantage of the ability to design without the design limitations that come into play with more traditional manufacturing methods.
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.
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..
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
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 :) )

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

Progress Breathtaking
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
About time you guys thought of this, should have bin done back in the 90s.

Imagine this tech becoming inexpensive enough for remote places like Greenland.
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 :) )
It might be the future of engineering and prototyping. manufacturing will be done with a cheaper faster process in most cases.
Machinist here, at my job we talk smack on our PBF Techs (Powder Bed Fusion) that all they do is operate an oversized Microwave 😂😂
I'd love to see a strength test.
You're wearing space-age respirators when you handle this stuff, but you don't put on Tyvek suits?
