Absolutely incredible! This allows us engineers to design much more advanced parts with internal features that previously couldn't be manufactured. This technology is a game-changer. Stronger, lighter, better designs!
Yes and no. These machines are awesome, but control over the finished cured size just isn't there. You can't count on a part like that staying within any amount of tolerance less than a few thou at absolute best. I've seen shops have to run a part like that 5-10 times just to get one that was in tolerance. It's super sensitive to laser temperature, layer temperature, powder temperature, etc. Much less the final sintering stages have to be dead on repeatable.
@@BrettFleming I think your point is very important to consider. 3D printing plastic is the same way. Consequently, in my lab, a "tolerance" parameter is used in CAD to attempt to "dial it in". Any luck in your metal shop attempting a similar procedure? Imagine having also to build a climate-controlled room to house your already expensive machine!
Process time and scrap rate will change your mind about metal 3d printing. Good for prototyping and rapid iteration. Ask for a lead time on 10000 of what he just made and you will see what I mean. Also no economies of scale so cost doesn't come down much if any at high production volumes.
@@BrettFleming Spot on. Some traditional machining will always be needed but its pretty wild seeing it advance this fast and this much. DMG MORI has a Combo 5-axis Mill with swappable Metal 3D Printing head pretty cool seeing the promo video of it at least. Print, Machine, add more material, then machine that.

@@BeastMode-ts6eg Technology brings not progress, but an illusion of progress. On our deathbed, 3D printers cannot help us to get a better next life nor tell us what is our next life going to be like. And yes life does not end with the death of the body, as most Westerners are taught to think.

Must of been a old powder bed system, the NASA SLA printers back then had pretty high resolution. The guys who created them went on to found stratasys and objet (as well as created the modern STL format)
When plastic 3d printing came out I thought that’s cool. But printing with metal, that’s a whole new level👍 I’m 57 now and wish I was 18 again so I could see all of the awesome things that will be created using tech like this over the next 50 years. Simply amazing
I'm skeptical if there are applications beyond prototyping and maybe replacing the odd spare part that can't be found elsewhere. Think of the energy it takes to basically laser weld all of the powder into one part. Traditional methods are still faster and cheaper for mass production.
@@ramdas363 Metallic sintering is used quite a bit in Formula 1 for both Race and Wind tunnel parts, and has been for the past 15 years - In Inconel, Titanium, Aluminium and Maraging steel. But yes, the volumes are far of being considered mass production.
I remember seeing something 3D printed using plastic for the first time years ago, and I remember saying or thinking "this is gonna change the meaning of the word 'printing.'" This kind of technology just keeps getting more and more incredible. Just imagine having a machine that hasn't had parts made for it in 30 years, you send in the part that needs to be replaced to have a 3D model of it made on a screen, and then it gets printed.
They are now printing organic material. Within 50 years humans will have access to printed skin. Noses and ears will be the easiest. Bone and organs might take some extra work.
I fixed up a part on my 20 year old motorhome this way. I destroyed one of the fiberglass wheel arch trims in an altercation with a fence. I used photogrammetry to scan the good side of the van into a 3d model, loaded it into the PC and mirrored it, CAD'd up a model that roughly followed the same shape, printed off a test of the full piece in plastic (had to do it in like 11 parts and glue together since my printer only handles 22cm cubed build volume) to ensure it fit to the vehicle, then printed a mould using the same CAD file to lay up fiberglass into.
We have printed complex parts like that at work and proem we ran into was getting the powder out of the internal tubes. Flushing with water only made the problem worse. We ended up having to make powder evacuation holes and then plug them once the passage ways were clear. Good luck
@@mattcook544 oh bummer was it a total redesign or can you write in different steps and galleries??,just out of interest how far do you test the part that's been "printed" what's the typical life expectancy compared to cast parts for instance an exhaust manifold? Also Is the part weldable? Sorry for the questions it's absolutely fascinating
My experience is that this heavily dependent on passage size, and if there are and 'hard' bends. Sub 2.5mm passages seem to have a pretty bad form if they aren't going in roughly perpendicular to the layers. I'm not sure where the cutoff is that a 90 or 180 degree bend can be done without issues as I've never designed anything with big enough passages.
Now were talking! DAMN! I made my own DIY Multi metal 3d printer it prints 600x900x135mm, THEN CNC's after that process to tolerance. unlimimited tooling recycling! Love this!
Wow, this is incredible! As a technology enthusiast, I'm blown away by the capabilities of this industrial 3D printer. The fact that it can print fully formed complex metal parts is mind-boggling, and I can only imagine the possibilities this opens up for multiple industries. The level of precision and detail is remarkable, and it's amazing to see how far 3D printing technology has come. I can't wait to see how this innovation will revolutionize the manufacturing world and beyond. Great video, thanks for sharing!
It is pretty neat. The parent company to the one I work for uses mostly CNC's and screw machines, but back in April they bought a 3d metal printing place. Recently we been getting insert holders with more efficient cooling channels for things like a muratecs, and okumas. Along with a ton of new insert designs. Right now they are just working with tool and die making but planning on more complicated designs for general market to our suppliers our CNC's and screws can't make.
Awesome! As an additive process, 3D printing is perfect, but I still think it will take a long time to completely reduce costs. CNC machining is still an important way to maintain costs.
The key benefit to 3D printing is a near-complete freedom of design. Additive manufacturing enables you to produce shapes that are simply impossible with conventional CNC methods. Cost isn't the main issue. If that better shape creates a superior product, then the increased production cost can be worth it. Example: Companies are now 3D printing injection moulding dies with conformal cooling channels, so cooling channels that closely follow the injection cavity. The example I saw had a cooling time of 5 seconds before part ejection. The conventional injection mould for the same part required 30 seconds of active cooling before ejection. Chopping 25 seconds of the cycle time is *HUGE* so the one-time extra production cost over conventional CNC parts is accepted without any issue. I've seen a 3D printed elbow joint for a concrete pumping setup. It was 10x the price of a conventional cast and machined part. But the prototype had been in service for 11 months straight, where the conventional part had to be replaced every 6 weaks because of wear. The AM part was much more shape-optimized so it would 1) last much longer and 2) cause a lot less down-time. Again, production cost isn't the primary concern. GE did a clean-sheet design of a new turbofan for the Cesna Denali, their new Catalyst engine. That new engine is lighter, more fuel efficient _and_ more powerful, thanks to 3D printing. They consolidated what traditionally would require some 800 separate components into *12* printed parts. Assembly is much easer, and much less fault-prone, the number of parts that require stocking is massively reduced, etc. Again: if additive manufacturing is more expensive than CNC (and it most definitely is!) then there are several ways to offset this with other benefits. But you really need clean-sheet designs for this to really pay off.
You're absolutely correct, but in 20-30 years this technology will have probably advanced enough to give it the edge over CNC even cost wise. I love the possibilities it opens.
Right now, I think the technology is best used as a prototyping device - you can work through a large number of iterations much more quickly and once you're settled on a finalized part, then you can move to traditional manufacturing methods to bring the per piece costs down.
@@bobdole4916 The biggest benefit of additive manufacturing is the near-complete freedom of design. Sure, it's great for prototyping of parts that can be produced conventionally, but its real advantage is that you can create shapes that are otherwise simply impossible to produce. That allows for new levels of weight saving, for new levels of parts integration, for new levels of shape optimisation, and so on. The new GE Catalyst turbofan engine? Complete clean-sheet design, made by additive manufacturing: lighter, more fuel efficient _and_ more powerful, and some 800 components consolidated into just 12. Will be available in the single prop new Cesna Denali. Prototyping you say? Condolences by the way, for your namesake.
Freaking awesome! I have been into 3d printing as a hobby for years and am just waiting for the costs to come down for a more hobbie style metal printer.
How strong are parts form printing ? For example 10mm pipe form printer and same pipe right from nearest store will have same strenght ? Part you have there is amazing and i'm blown away. Absolutely impossible to make in traditional way.
The difference heavily depends on the materials. For steel the best 3D printed material is a lot weaker than what can be produces by other means (single crystal steel for aviation), on other materials their characteristics are near identical.
I mean - yes, this EXACT part is not possible to produce with other methods. You'd need to make it at least 3-parts with normal methods, but those are then also way faster and cheaper for larger production scale - and for nearly anything you want to actually produce that will make 3D printing not an option for scale production. But it is a great tool for research and small-scale production.
Wow, just wow. I am not an engineer, but anyone can see the amazing potential of 3D printing steel. We've seen plastic gadgets being printed for years, curiosities mostly. But complex steel parts, gamechanger! Engineer Designers may have been able to dream up parts that theoretically would function in a certain way on computer models and not be able to build them. This changes everything.
Very interesting. I’d like to see what would happen if you dropped it on the floor. Part of me thinks it will shatter like porcelain vase. I’m curious, so please drop it and let’s see what happens.
Metal printed parts have nearly the same properties as their cast counterparts. Usually around 95% if I recall. Should be as strong as a cast or milled part for most intents and purposes
Given that it's 316L and that it's a selective laser melting (SLM) printer, you're looking at 99,5% density or better. It will sit between cast 316L in terms of strenght, and billet 316L. The grain size will be better than as-cast, but it will not (yet) meet properties of forged 316L. Given that 316L is highly ductile, it will dent or bend, depending from the drop height and angle of impact. But it all depends on the printing method: the laser power, the spot size, the scanning pattern, single melting or remelting, layer height, the powder quality, and so on.
@@PrintsandProps See my other reply: properties depend on a lot of factors. Selective laser sintering (SLS) can get up to 95% density, Selective Laser Melting (SLM) which this TRUMP printer does, can surpass 99,5% density. 3D printed parts can exceed as-cast properties, getting close to forged billet.
@@yanicktanguay2746 uh...sorry but that is a terrible analogy. Do you have any science or engineering knowledge at all? There is this thing called Enthalpy of Fusion that you would know about if you could pass a college level science class. It takes a LOT of energy to change the phase of a metal from solid to liquid so it will fuse. Energy costs. And the components to handle and transform lots of energy cost lots of money. Advancements in technology can not change the laws of physics and thermodynamics.
@@shooter7a no I'm not a master or any scientific. But I'm only a student of 25 y/o I bet in 75 years. We will discovert many way to produce energy, maybe solar, hydrogen, nuclear...
I was wondering, how smooth are the printed surfaces? Since this part will be transporting a fluid through its tubes, I wonder if the surface left by the printer increases drag and turbulences
Because this is a heat transfer component I think the turbulence and increased surface area would be net positive. Based on how narrow the tubes are I would guess that pressure loss isn't something they are concerned about.
The surface finish is half the diameter of the particles, so pretty rough. Maybe 800 grit sandpaper. After looking it up the particles are around 30 micron.
The surface finish almost certainly does increase resistance, but 3D printing lets you reduce the size of the component so much that you often end up with lower overall drag.
@@JamesSeedorf I mean... valid point but I wasn't really wondering the efficency for that particular application. Rather in general for fluid transportation. I guess I should have phrased my question a bit differently^^
Neat, but it still has many limitations. I can't imagine the flow-rate for fluid lines being terribly healthy with such a rough surface. Pressure and stress-concentration limits are likely to suffer quite a bit as well. I can imagine that the more complicated the part, the more surface finishing is sure to be quite the new and challenging conundrum.
The material removal won't be uniform and will concentrate on points and areas like the outer side of a bend. Even an abrasive line that can be used both in tensing and compression has limits. And when dealing with high stress/pressure , any rough, sharp feature can became a focus for stress concentration and shearing/fracturing. Very smooth surfaces are necessary if you're working near the limits of a material.
@@FiltyIncognito might be true for pressure applications but then Porsche already used this tech for pistons years ago. In series production. Sure it's not perfect yet but especially for the automotive industry it can replace casting completely. Have you ever seen water channels in an engine block to be sanded or polished after casting
Honestly, I'm not sure how to succinctly reply. It'd be easier to just hand you a textbook on manufacturing processes. The limitations of 3D printing are well documented. It's a great publicity stunt, though.
@@FiltyIncognito im sure everyone who made breakthroughs and innovations only followed textbooks. If you understand engineering then you can understand improvements in tech, for now it's amazing. But it's not meant to replace other forms of manufacturing, just offer another option. If it can make impossible parts, even if not at peak efficiency, that sounds like a big win. Fine tuning and tech will get it to where it's most likely one day a major manufacturing process. I'd imagine it does have limitations, but doesn't everything?
It won't be cheap, but if there is no viable manufacturing alternative then you have to pay the price. I'm sure costs will come down as this becomes more mainstream.
Just as a best eyeballed guesstimate from someone that does this, you're probably looking at 2-3 days to print then another few hours to cut that off the build plate if that's all you want to do (there is often some post-processing depending on your needs). With just that, I'd say maybe around $10k.
This part looks 'designed to look cool' more than it being designed to be the best part for a given application. Do the curved heat exchanger tubes really add anything of value?
it's not even a heat exchanger large flanges on the side for coolant to be passed through would make sense . but it's really just a useless part that looks cool until you ask yourself WTF is that for.
I just finished designing and building a complex kitchen appliance with a PLA printer, and was blown away by the ability to adjust the design on the fly. Imagine having to make a separate injection mold for each design iteration! It really was fun. But to do it in metal...
Ok but what about the reliability of the part? I know it looks nice and optimal design but aerospace and car parts are put through repetitive and grueling stress and the question I'm asking is if that method of manufacturing can make parts which won't fall apart under those conditions.
So, do I assume correctly that this is a test-print with an opening in the side to showcase the innards? Because for a functioning part, that side opening doesn't make sense at all.
Neat part but completely wrong machine for it. The liquid jacket is completely non-functional and you can't print it functional because it would just encapsulate the powder. This part should have been made on a direct laser deposition machine and not an SLS.
@@Vel0cir you could get most powder out but there's still plenty of powder left in there to contaminate your cooling system and depending on which pump is used, completely destroy it.
Let's put it this way, the machine is great, the technology is great, but cut the crappy "music" like you are trying to build suspense, it ain't happening. It is false, fake, and definitely overblown. The part itself is enough.
Amazed with the shape you achieved! I am wondering just one thing, which treatment do you use to reduce the rugosity of the internal side of the pipes?
With this tech and others 3d printing in space is not impossible with any part now. This is amazing. Ever since i heard of 3d printing i had always had that lingering question. How do u 3d print metal. This is awsome. Super impressive.
And this is just one of _several_ methods of direct metal printing. There are powder bed methods and powder spraying methods. There are also wire-based methods. Heating sources can be laser, electron beam, arc or electrical resistance. And then there is indirect metal printing, with metal powder and a binder, which can be jetted or printed from filament, which needs de-binding and sintering as post-process. Really there is _so much_ going on in Additive Manufacturing, it's mesmerising!
@@jacobanderson6551 Bingo! Powder bed = small build volume, high resolution, low kg/hour build rates. Wire methods = large size, low resolution, high kg/hour build rates. (The Dutch company MX3D printed an award winning pedestrian bridge spanning over 12 m using Wire Arc Additive Manufacturing!) Powder spraying methods sit in the middle ground. And powder+binder followed by debinding+sintering has its own drawbacks but is much better suited for higher parts count production.
It's awesome but how strong is the part! If you want to sell the machines abilities, then you need to demonstrating the strength and quality of the parts created!!! Technology these days are absolutely amazing!!!
Truly amazing, but I do have one question, do parts like that need any sort of annealing or post heat treatment? I would think that it would be like welding layer after layer, I just sometimes think about sintering sort of effect,possibly due to appearance of outsides. I also am aware that it is 316L SS, which wouldn't need annealing and hardening after, but what about other materials like high carbon steels? Awesome result, and amazing tech. Thanks for showing us.
This printing technology honestly makes me think of the potential advancements we can make in space travel and what not. More efficient, faster space travel. Potentially unlocking things we deemed never possible.
the powerpack (turbopump assembly) on most modern rocket engines are made almost entirely with additive manufacturing. Laser powder bed machines such as the one in this video are responsible for nearly every rocket engine fuel injector made over the last 15 years. Space hardware is a unique industry with low volume requirements but extreme high precision, its basically the ideal industry for additive to get a foothold.
There is little that "better parts" is going to do to make space travel more efficient. The issue is thermodynamics. The potential energy of rocket fuels vs mass.
@@shooter7a so realistically, we need to look into alternative "fuel", whatever that may be. Then when we discover something different than what we have available now, the additive manufactured parts could play a bigger role with reimagined fuel source/engine designs.
"whatever that may be". LOL. Do you know anything about the history of rocket propulsion and rocket fuels? You act like chemists have not been trying for 50+ years to come up with something better. About 170 different propellants made of liquid fuel have been tested, excluding minor changes to a specific propellant such as propellant additives, corrosion inhibitors, or stabilizers. In the U.S. alone at least 25 different propellant combinations have been flown. As of 2020, no completely new propellant has been used since the mid-1970s. Sorry...there is nothing new out there to "find". Go learn about chemistry and thermodynamics.
I worked at a place that printed cobalt-chrome dental fixtures. It set up from metal powder kind of like this machine. The metal powder is expensive, and water soluble. We used a six micron sieve to reuse the old powder. I was told that wearing any covid face covering would be sufficient. It wasn't, so I wore the common respirator I was given for belt sawing through supports to freeing the pieces from a steel plate. That was also insufficient, because the powder particles may have been too small to be stopped by the filter to begin with, but they definitely were after being sieved down. When reaching into the machine I could feel the particles crossing my tongue and hitting my throat. On top of that, the fact the powder was water soluble means it can pass through the skin. The sieve process was done pneumatically with the 3D printer's door open for the air lines to reach in. The powder was everywhere, in the air and a thick layer on top of everything. Cobalt-chrome is very unhealthy. My whole body started to go numb. I had to quit the job. The people who wear there had a strange acne along their hairline, like their skin was starting to fall apart. It took many months before I could feel my heart beating again. It is still hard to detect. unlike it was before I took the job. I can feel sore spots in my lungs that haven't gone away. It is harder to breath. I feel like this business I worked for took decades off my life, and I my have extra difficulty having children. It is also very bad for the environment. They are killing people there to turn a profit. I often want to press legal charges to hold them responsible for their actions, but I doubt I have enough evidence to convict. I wish I had never worked there.
That's a very very tough spot to be in. I'm not a lawyer, but my impression from what you describe is that you really should consult a proper one to figure out your options. This is printing is with 316L, not cobalt-chrome, and nowadays health and safety surrounding powder handling are quite a bit different from the situation you describe. With these modern powder bed printers, safe powder handling (both from a explosion hazard and a health hazard) is pretty much assured.
Did you also get feedback from your client on the effect of surface quality on the flow of the fluids? As beautiful as this is (seriously) the surface still looks a bit like 180 grit sandpaper. But as always, thanks for sharing. You guys rock
since you have the cutaway put in, you should check for leaks in a way thats easy for viewers to see. You can fill that center bit with liquid and apply a pressure and see if any bubbles come up.
Woooooow, can any one imagine the scfi behind this tech. You should have prior exp in the field to understand it. Im only 25 yr and 3 years of exp and i'm impressed👏👏🔥🔥🔥🔥🔥🔥🔥
You deposite a thin layer of very fine metal powder with a special wiper. A laser (or in this case multiple lasers) locally melt the powder and let the particles fuse, only where the part is to be build. The wiper passes again to remove any spatter. Then the wiper makes another pass to deposite a new layer of metal power on top of the just printed/build layer and in go the lasers once again to selectively melt the next build layer. Then another wipe to remove spatter, and another wipe to deposite a fresh layer. "Rinse and repeat" untill done. Carefully remove printed part from the remaining unmelted powder.

2:25 what about realibility? i mean no need to be hardened or sinterized? i mean heat preparation to reduce stress ... that kind of thing we have to make to nowday materials. Or it can be used right from 3D print?
I am wondering tho: how good is the surface roughness on the inside of these tubes when printed? I can understand that will heavily affect you pressure losses within those channels.
It would be interesting to see finishing the ports, turn the faces and finishing the printed thread diameter. Like anyone else who is bit skeptical of the costly process, but also curious would like to see more detail in bond porosity, resolution control and consumable rates. Does the machine log the gas consumed to maintain the work envelope?
I honestly do believe that advances in 3D-Print can help to lift-up several research-areas (in practical and theoretical terms) when it comes to new materials, theoretical concepts, Applied Advanced Engineering (in every area, from construction to fluids and aerodynamics) Art and even food itself someday (which, when it comes to food, it shouldn't imo, but the reality is that we don't know what will be societal status-quo in the next 100-200 years tbh). Imo 3D-Print has the very real potential (when included in other areas of expertise) to kickstart a genuine new Industrial Revolution, and a much more advanced and sustainable one tbh.
Not sure if anyone asked and sorry if a repeat. What is the strength and or pressure limitations with using a powered material vs casting? Bending moment or vibration concerns mainly.
if i recall, there was a car made with parts that used this process, AI designed the parts to where they were crazy light, yet strong enough to handle being pretty integral parts, ie suspension arms and more than a few frame components
Does the part receive any heat treatment after fabrication such as sintering or HIP? How dense is the final metal? What does the raw material cost and how is it made. Can some parts be made from plain carbon steel? What technical advances been made over the last two years.
I started my technical career 43 years ago at a company that made powdered metal parts for the auto industry. Parts were pressed out of powdered metal using dies and punches. The green parts would be sintered on conveyor belts through long furnaces. At the time it was very high tech. Looking at the part made in the video now seems like magic. 3D models laser sintered into very unique and complex parts with out expensive tooling seems like we’re getting nearer to the replicator technology used in Star Trek. Simply amazing.
QUESTION: I have been searching for information on the heat treatment of 3D printed metals, hardening of steel to be exact, and have not found much on the matter. Can these components be heat treated after printing? Thanks in advance.
I'm so excited to see where additive manufacturing is going, take a look at some of the heat exchanger designs using triply periodic minimal surfaces that are being designed, it's changing the way we can think about designing from, best compromise to best theoretical solution.

I used photogrammetry to scan the good side of the van into a 3d model, loaded it into the PC and mirrored it, CAD'd up a model that roughly followed the same shape, printed off a test of the full piece in plastic (had to do it in like 11 parts and glue together since my printer only handles 22cm cubed build volume) to ensure it fit to the vehicle, then printed a mould using the same CAD file to lay up fiberglass into.
@@wyvvernstone “Your scientists were so preoccupied with whether or not they could, they didn’t stop to think if they should.”
We have printed complex parts like that at work and proem we ran into was getting the powder out of the internal tubes. Flushing with water only made the problem worse. We ended up having to make powder evacuation holes and then plug them once the passage ways were clear. Good luck
Did you try high frequency vibration and an air-blast to fluidize and clear the bulk of the powder?
Ultrasonic cleaning?? 🤔
@@hoping67 sadly didn't work. We ended up having to reprint the part.
@@mattcook544 oh bummer was it a total redesign or can you write in different steps and galleries??,just out of interest how far do you test the part that's been "printed" what's the typical life expectancy compared to cast parts for instance an exhaust manifold? Also Is the part weldable? Sorry for the questions it's absolutely fascinating
My experience is that this heavily dependent on passage size, and if there are and 'hard' bends. Sub 2.5mm passages seem to have a pretty bad form if they aren't going in roughly perpendicular to the layers. I'm not sure where the cutoff is that a 90 or 180 degree bend can be done without issues as I've never designed anything with big enough passages.
Incredible. Still looking forward to that full depth slot through a china vise 👀 gonna be epic
We purchased the vise😂😂😂
Waiting for it to arrive
@@TITANSofCNC awesome!
Lol that was a great idea, i cant wait
As a one time machinist/tool and die man I have to say, I am AMAZED at the new technology that's come out the past 10 years.
This is some space age technology and the team you have is just awesome. One word comes to mind: wow!
Been around since the 70's too
@@jonhaze7537 insane when you think about it. Just like the SR-71 reading about the tech in that aircraft to be designed and built back then.
Now were talking! DAMN! I made my own DIY Multi metal 3d printer it prints 600x900x135mm, THEN CNC's after that process to tolerance. unlimimited tooling recycling! Love this!
Wow, this is incredible! As a technology enthusiast, I'm blown away by the capabilities of this industrial 3D printer. The fact that it can print fully formed complex metal parts is mind-boggling, and I can only imagine the possibilities this opens up for multiple industries. The level of precision and detail is remarkable, and it's amazing to see how far 3D printing technology has come. I can't wait to see how this innovation will revolutionize the manufacturing world and beyond. Great video, thanks for sharing!
i made chatgpt write that for me.
This technology is absolutely mind-blowing! I can't wait to see more videos about the capabilities of this printer!
It is pretty neat. The parent company to the one I work for uses mostly CNC's and screw machines, but back in April they bought a 3d metal printing place. Recently we been getting insert holders with more efficient cooling channels for things like a muratecs, and okumas. Along with a ton of new insert designs. Right now they are just working with tool and die making but planning on more complicated designs for general market to our suppliers our CNC's and screws can't make.
Awesome! As an additive process, 3D printing is perfect, but I still think it will take a long time to completely reduce costs. CNC machining is still an important way to maintain costs.
The key benefit to 3D printing is a near-complete freedom of design. Additive manufacturing enables you to produce shapes that are simply impossible with conventional CNC methods. Cost isn't the main issue. If that better shape creates a superior product, then the increased production cost can be worth it.
Example: Companies are now 3D printing injection moulding dies with conformal cooling channels, so cooling channels that closely follow the injection cavity. The example I saw had a cooling time of 5 seconds before part ejection. The conventional injection mould for the same part required 30 seconds of active cooling before ejection. Chopping 25 seconds of the cycle time is *HUGE* so the one-time extra production cost over conventional CNC parts is accepted without any issue.
I've seen a 3D printed elbow joint for a concrete pumping setup. It was 10x the price of a conventional cast and machined part. But the prototype had been in service for 11 months straight, where the conventional part had to be replaced every 6 weaks because of wear. The AM part was much more shape-optimized so it would 1) last much longer and 2) cause a lot less down-time. Again, production cost isn't the primary concern.
GE did a clean-sheet design of a new turbofan for the Cesna Denali, their new Catalyst engine. That new engine is lighter, more fuel efficient _and_ more powerful, thanks to 3D printing. They consolidated what traditionally would require some 800 separate components into *12* printed parts. Assembly is much easer, and much less fault-prone, the number of parts that require stocking is massively reduced, etc. Again: if additive manufacturing is more expensive than CNC (and it most definitely is!) then there are several ways to offset this with other benefits. But you really need clean-sheet designs for this to really pay off.
You're absolutely correct, but in 20-30 years this technology will have probably advanced enough to give it the edge over CNC even cost wise. I love the possibilities it opens.
Right now, I think the technology is best used as a prototyping device - you can work through a large number of iterations much more quickly and once you're settled on a finalized part, then you can move to traditional manufacturing methods to bring the per piece costs down.
@@bobdole4916 The biggest benefit of additive manufacturing is the near-complete freedom of design.
Sure, it's great for prototyping of parts that can be produced conventionally, but its real advantage is that you can create shapes that are otherwise simply impossible to produce.
That allows for new levels of weight saving, for new levels of parts integration, for new levels of shape optimisation, and so on.
The new GE Catalyst turbofan engine? Complete clean-sheet design, made by additive manufacturing: lighter, more fuel efficient _and_ more powerful, and some 800 components consolidated into just 12. Will be available in the single prop new Cesna Denali. Prototyping you say?
Condolences by the way, for your namesake.
@@Hydrazine1000 I hadn't considered products that would have a low production quantity - very good point.
Freaking awesome! I have been into 3d printing as a hobby for years and am just waiting for the costs to come down for a more hobbie style metal printer.
That could take a while, I an thinking $5k or less for "hobbyists" and even that isn't cheap.
How strong are parts form printing ? For example 10mm pipe form printer and same pipe right from nearest store will have same strenght ? Part you have there is amazing and i'm blown away. Absolutely impossible to make in traditional way.
The 3d printed wont be as strong
SLM printed parts typically have a martensite grain structure, not sure with this machine in particular since it's "multi-laser"
The difference heavily depends on the materials.
For steel the best 3D printed material is a lot weaker than what can be produces by other means (single crystal steel for aviation), on other materials their characteristics are near identical.
I mean - yes, this EXACT part is not possible to produce with other methods. You'd need to make it at least 3-parts with normal methods, but those are then also way faster and cheaper for larger production scale - and for nearly anything you want to actually produce that will make 3D printing not an option for scale production.
But it is a great tool for research and small-scale production.
Mind - BLOWN!!!!!!! The small scale surprised me, but that is only a matter of scale.
This is the level of 3d printing I expect from Titans of CNC !
Wow, just wow. I am not an engineer, but anyone can see the amazing potential of 3D printing steel. We've seen plastic gadgets being printed for years, curiosities mostly. But complex steel parts, gamechanger! Engineer Designers may have been able to dream up parts that theoretically would function in a certain way on computer models and not be able to build them. This changes everything.
Would have liked to know how long it took to print.
17 years
That's just sick, I'm floored by the level of detail....
Very interesting. I’d like to see what would happen if you dropped it on the floor. Part of me thinks it will shatter like porcelain vase. I’m curious, so please drop it and let’s see what happens.
Metal printed parts have nearly the same properties as their cast counterparts. Usually around 95% if I recall. Should be as strong as a cast or milled part for most intents and purposes
It will dent or bend at the impacted area instead of shatter
@@PrintsandProps I’m not sure they are quite at that level, especially in fatigue properties
It’s very impressive though
Given that it's 316L and that it's a selective laser melting (SLM) printer, you're looking at 99,5% density or better. It will sit between cast 316L in terms of strenght, and billet 316L. The grain size will be better than as-cast, but it will not (yet) meet properties of forged 316L. Given that 316L is highly ductile, it will dent or bend, depending from the drop height and angle of impact.
But it all depends on the printing method: the laser power, the spot size, the scanning pattern, single melting or remelting, layer height, the powder quality, and so on.
@@PrintsandProps See my other reply: properties depend on a lot of factors. Selective laser sintering (SLS) can get up to 95% density, Selective Laser Melting (SLM) which this TRUMP printer does, can surpass 99,5% density. 3D printed parts can exceed as-cast properties, getting close to forged billet.
Things have progressed very well since my first exposure to metallic 3D printing in engineering school in the early 2000s. 😁👍
Makes the octopus look old school
WoW what's next it's all evolving FAST, Titan keep on keeping on
I love the freedom of creativity that 3D printing gives us.
Can't wait till we get similar capabilities in our home 3D printers at affordable costs. That would be a game changer!
Never happen. You need to MELT/FUSE metal. That is never going to be cheap.
@@shooter7a that what they said in 1890 for car. Horse will always be faster and cheaper..
@@yanicktanguay2746 uh...sorry but that is a terrible analogy. Do you have any science or engineering knowledge at all? There is this thing called Enthalpy of Fusion that you would know about if you could pass a college level science class.

Advancements in technology can not change the laws of physics and thermodynamics.

Incredible part design and printer capability! Thanks for sharing.
TITAN FOR PRESIDENT!!!!!!!!
is the powder filtered and directly reused? in what percentage reused? how many times can it be reused?
In these types of machines the powder is re used. Nearly 100% of the powder is recoverable
I think the powder going bad issue is a thermoplastic thing
Jaw dropping stuff...and the music; right out of Terminator. There's no stopping it.
Looks like a heat defuser for a spaceship anyway designs like this is one of the reasons I got into 3D printing
This is awesome! Bring raw materials to space, 3d parts to build space stations, spaceships, just about anything.
I was wondering, how smooth are the printed surfaces? Since this part will be transporting a fluid through its tubes, I wonder if the surface left by the printer increases drag and turbulences
Because this is a heat transfer component I think the turbulence and increased surface area would be net positive. Based on how narrow the tubes are I would guess that pressure loss isn't something they are concerned about.
The surface finish is half the diameter of the particles, so pretty rough. Maybe 800 grit sandpaper. After looking it up the particles are around 30 micron.
@@d3m0n54in7 thanks
The surface finish almost certainly does increase resistance, but 3D printing lets you reduce the size of the component so much that you often end up with lower overall drag.
@@JamesSeedorf I mean... valid point but I wasn't really wondering the efficency for that particular application.
Rather in general for fluid transportation.
I guess I should have phrased my question a bit differently^^
I am truly amazed this is like getting to ultimate use of technologies for unbelievable advantages
Looks like they have really stepped up the parts finish since I last saw these in action!
Very good to print couple of items, can't see it being used in mass production.
Neat, but it still has many limitations. I can't imagine the flow-rate for fluid lines being terribly healthy with such a rough surface. Pressure and stress-concentration limits are likely to suffer quite a bit as well.
I can imagine that the more complicated the part, the more surface finishing is sure to be quite the new and challenging conundrum.
If stuff flows thru it, can you not sandblast the interior? With like, probing lines similar to those plumbing cameras or laproscopy tools?
The material removal won't be uniform and will concentrate on points and areas like the outer side of a bend. Even an abrasive line that can be used both in tensing and compression has limits.
And when dealing with high stress/pressure , any rough, sharp feature can became a focus for stress concentration and shearing/fracturing. Very smooth surfaces are necessary if you're working near the limits of a material.
@@FiltyIncognito might be true for pressure applications but then Porsche already used this tech for pistons years ago. In series production. Sure it's not perfect yet but especially for the automotive industry it can replace casting completely. Have you ever seen water channels in an engine block to be sanded or polished after casting
Honestly, I'm not sure how to succinctly reply. It'd be easier to just hand you a textbook on manufacturing processes.
The limitations of 3D printing are well documented.
It's a great publicity stunt, though.
@@FiltyIncognito im sure everyone who made breakthroughs and innovations only followed textbooks.
If you understand engineering then you can understand improvements in tech, for now it's amazing. But it's not meant to replace other forms of manufacturing, just offer another option. If it can make impossible parts, even if not at peak efficiency, that sounds like a big win. Fine tuning and tech will get it to where it's most likely one day a major manufacturing process. I'd imagine it does have limitations, but doesn't everything?
BOOM! Looks gorgeous I got plastic beaters for printers. But this makes me want the REAL. Glad I got to view this post in time ❤️
PLEASE TELL US HOW LONG IT WAS PRINTED? WHAT'S HARDNESS?
It’s like the material that you print with so if this was 316 it would be soft. We run 17/4 so you can heat treat it after and it gets “hard”
I absolutely love that yall are so passionate about this.
Great to see this stuff 😎👍 keep up the good work 🙂
What about porosity? How much leakage occurs at operating conditions? What sort of pressure can this manifold hold?
There is a good reason why they don't talk about it, the strength is much much lower.
What kind of print time is that? and what would each part cost? I have to imagine it's a lot
It won't be cheap, but if there is no viable manufacturing alternative then you have to pay the price. I'm sure costs will come down as this becomes more mainstream.
Just as a best eyeballed guesstimate from someone that does this, you're probably looking at 2-3 days to print then another few hours to cut that off the build plate if that's all you want to do (there is often some post-processing depending on your needs). With just that, I'd say maybe around $10k.
That part is so alien looking!
This part looks 'designed to look cool' more than it being designed to be the best part for a given application.
Do the curved heat exchanger tubes really add anything of value?
Not to mention the opening on the side...?
I guess being curved, they have extra length,hence extra surface for heat exchange
it's not even a heat exchanger large flanges on the side for coolant to be passed through would make sense . but it's really just a useless part that looks cool until you ask yourself WTF is that for.
I just finished designing and building a complex kitchen appliance with a PLA printer, and was blown away by the ability to adjust the design on the fly. Imagine having to make a separate injection mold for each design iteration! It really was fun. But to do it in metal...
Can't wait until metal 3d printing can become useable for home use.
Ok but what about the reliability of the part? I know it looks nice and optimal design but aerospace and car parts are put through repetitive and grueling stress and the question I'm asking is if that method of manufacturing can make parts which won't fall apart under those conditions.
I thought GE was using these for jet engine parts years ago.
For Raptors? 🤔
Good old Trumpf. Been programming all kinds of weird stuff on their CNC break. Can't say their proprietary software is the best but gotta do it.
So, do I assume correctly that this is a test-print with an opening in the side to showcase the innards? Because for a functioning part, that side opening doesn't make sense at all.
Likely a show piece yes
Came to ask the same thing, it must be a show piece to display the internal structure.
well I guess if you want to see if the internals turn out OK, you need to have a window in one first before you go making the real part.
How do you even model something that advanced, absolutly amazing
Neat part but completely wrong machine for it. The liquid jacket is completely non-functional and you can't print it functional because it would just encapsulate the powder. This part should have been made on a direct laser deposition machine and not an SLS.
It has ports for the heat exchange fluid, so you could get the powder out of those.
@@Vel0cir you could get most powder out but there's still plenty of powder left in there to contaminate your cooling system and depending on which pump is used, completely destroy it.
Holy cow! That is absolutely AMAZING!
How was the powder removal from those channels? And how did you arrive at Trumpf as your laser powder bed machine of choice?
I just hope manufacturers don't start using this method to create pieces that are impossible to service!
Great job on the print!
That's the whole perpus of doing it
You have to buy new.
It's a disposable world now.
Let's put it this way, the machine is great, the technology is great, but cut the crappy "music" like you are trying to build suspense, it ain't happening. It is false, fake, and definitely overblown. The part itself is enough.
Very American
i havent even watched the video and i already agree with you
Some of us LIKE it. It's appropriate to the feeling we have when watching it.
Amazed with the shape you achieved! I am wondering just one thing, which treatment do you use to reduce the rugosity of the internal side of the pipes?
i wonder the same, looks a bit rough
Extrusion honing would probably be the best
i just bought my first 3d printer... it's nothing much but I love the ability of converting 3d picture into an actual physial object i can touch
Amazing how far everything has come over the last 10 year 👏👏🤟👊
This is a massive game changer for the future. Almost as close as the invention of the semi-conductor.
Salute to the minds of these scholars
With this tech and others 3d printing in space is not impossible with any part now. This is amazing. Ever since i heard of 3d printing i had always had that lingering question. How do u 3d print metal. This is awsome. Super impressive.
And this is just one of _several_ methods of direct metal printing. There are powder bed methods and powder spraying methods. There are also wire-based methods. Heating sources can be laser, electron beam, arc or electrical resistance.
And then there is indirect metal printing, with metal powder and a binder, which can be jetted or printed from filament, which needs de-binding and sintering as post-process.
Really there is _so much_ going on in Additive Manufacturing, it's mesmerising!
Sounds like each meathod could be better for diffrent parts.
@@jacobanderson6551 Bingo! Powder bed = small build volume, high resolution, low kg/hour build rates. Wire methods = large size, low resolution, high kg/hour build rates. (The Dutch company MX3D printed an award winning pedestrian bridge spanning over 12 m using Wire Arc Additive Manufacturing!) Powder spraying methods sit in the middle ground.
And powder+binder followed by debinding+sintering has its own drawbacks but is much better suited for higher parts count production.
It's awesome but how strong is the part! If you want to sell the machines abilities, then you need to demonstrating the strength and quality of the parts created!!! Technology these days are absolutely amazing!!!
3d printing is truly a revolution.
Funnily enough I once got to do a placement at a Trumpf factory in Germany for a scool project... and man these machines are insane!
I just now found out that you could 3-D print alloy
steel like I "PMI" every day.
Stainless and INCO-601 thru INCO-800 to?
INCREDIBLE !!!!!
How long does it take to 3D print something like this? The detail and accuracy is incredible. Easy as scanning a 3D object and printing the result.
Love technology that helps improve lives.
it has the precision of a todler drawing a circle. Great
Truly amazing, but I do have one question, do parts like that need any sort of annealing or post heat treatment? I would think that it would be like welding layer after layer, I just sometimes think about sintering sort of effect,possibly due to appearance of outsides. I also am aware that it is 316L SS, which wouldn't need annealing and hardening after, but what about other materials like high carbon steels? Awesome result, and amazing tech. Thanks for showing us.
Mazak has an amazing line of conversational subtractive / additive hybrid machine.
This printing technology honestly makes me think of the potential advancements we can make in space travel and what not. More efficient, faster space travel. Potentially unlocking things we deemed never possible.
the powerpack (turbopump assembly) on most modern rocket engines are made almost entirely with additive manufacturing. Laser powder bed machines such as the one in this video are responsible for nearly every rocket engine fuel injector made over the last 15 years. Space hardware is a unique industry with low volume requirements but extreme high precision, its basically the ideal industry for additive to get a foothold.
There is little that "better parts" is going to do to make space travel more efficient. The issue is thermodynamics. The potential energy of rocket fuels vs mass.
@@shooter7a so realistically, we need to look into alternative "fuel", whatever that may be. Then when we discover something different than what we have available now, the additive manufactured parts could play a bigger role with reimagined fuel source/engine designs.
"whatever that may be". LOL. Do you know anything about the history of rocket propulsion and rocket fuels? You act like chemists have not been trying for 50+ years to come up with something better.
About 170 different propellants made of liquid fuel have been tested, excluding minor changes to a specific propellant such as propellant additives, corrosion inhibitors, or stabilizers. In the U.S. alone at least 25 different propellant combinations have been flown. As of 2020, no completely new propellant has been used since the mid-1970s.
Sorry...there is nothing new out there to "find". Go learn about chemistry and thermodynamics.

I worked at a place that printed cobalt-chrome dental fixtures. It set up from metal powder kind of like this machine. The metal powder is expensive, and water soluble. We used a six micron sieve to reuse the old powder. I was told that wearing any covid face covering would be sufficient. It wasn't, so I wore the common respirator I was given for belt sawing through supports to freeing the pieces from a steel plate. That was also insufficient, because the powder particles may have been too small to be stopped by the filter to begin with, but they definitely were after being sieved down. When reaching into the machine I could feel the particles crossing my tongue and hitting my throat. On top of that, the fact the powder was water soluble means it can pass through the skin. The sieve process was done pneumatically with the 3D printer's door open for the air lines to reach in. The powder was everywhere, in the air and a thick layer on top of everything. Cobalt-chrome is very unhealthy. My whole body started to go numb. I had to quit the job. The people who wear there had a strange acne along their hairline, like their skin was starting to fall apart. It took many months before I could feel my heart beating again. It is still hard to detect. unlike it was before I took the job. I can feel sore spots in my lungs that haven't gone away. It is harder to breath. I feel like this business I worked for took decades off my life, and I my have extra difficulty having children. It is also very bad for the environment. They are killing people there to turn a profit. I often want to press legal charges to hold them responsible for their actions, but I doubt I have enough evidence to convict. I wish I had never worked there.
That's a very very tough spot to be in. I'm not a lawyer, but my impression from what you describe is that you really should consult a proper one to figure out your options.
This is printing is with 316L, not cobalt-chrome, and nowadays health and safety surrounding powder handling are quite a bit different from the situation you describe. With these modern powder bed printers, safe powder handling (both from a explosion hazard and a health hazard) is pretty much assured.
Did you also get feedback from your client on the effect of surface quality on the flow of the fluids?
As beautiful as this is (seriously) the surface still looks a bit like 180 grit sandpaper.
But as always, thanks for sharing. You guys rock
since you have the cutaway put in, you should check for leaks in a way thats easy for viewers to see. You can fill that center bit with liquid and apply a pressure and see if any bubbles come up.
Woooooow, can any one imagine the scfi behind this tech. You should have prior exp in the field to understand it. Im only 25 yr and 3 years of exp and i'm impressed👏👏🔥🔥🔥🔥🔥🔥🔥
You deposite a thin layer of very fine metal powder with a special wiper. A laser (or in this case multiple lasers) locally melt the powder and let the particles fuse, only where the part is to be build. The wiper passes again to remove any spatter. Then the wiper makes another pass to deposite a new layer of metal power on top of the just printed/build layer and in go the lasers once again to selectively melt the next build layer. Then another wipe to remove spatter, and another wipe to deposite a fresh layer. "Rinse and repeat" untill done. Carefully remove printed part from the remaining unmelted powder.
As you've rightly noted, you don't have the maturity and knowledge necessary to enable you to UNDERSTAND this, but you're 'IMPRESSED'.

Not sure if anyone asked and sorry if a repeat.
What is the strength and or pressure limitations with using a powered material vs casting? Bending moment or vibration concerns mainly.
if i recall, there was a car made with parts that used this process, AI designed the parts to where they were crazy light, yet strong enough to handle being pretty integral parts, ie suspension arms and more than a few frame components
Does the part receive any heat treatment after fabrication such as sintering or HIP? How dense is the final metal? What does the raw material cost and how is it made. Can some parts be made from plain carbon steel? What technical advances been made over the last two years.
I started my technical career 43 years ago at a company that made powdered metal parts for the auto industry. Parts were pressed out of powdered metal using dies and punches. The green parts would be sintered on conveyor belts through long furnaces. At the time it was very high tech. Looking at the part made in the video now seems like magic. 3D models laser sintered into very unique and complex parts with out expensive tooling seems like we’re getting nearer to the replicator technology used in Star Trek. Simply amazing.
QUESTION: I have been searching for information on the heat treatment of 3D printed metals, hardening of steel to be exact, and have not found much on the matter. Can these components be heat treated after printing? Thanks in advance.
I'm so excited to see where additive manufacturing is going, take a look at some of the heat exchanger designs using triply periodic minimal surfaces that are being designed, it's changing the way we can think about designing from, best compromise to best theoretical solution.
