@@tonyg3091 yeah xD captain obvious! some are even cheaper like planext x.. but still most of titanium frames are too expensive or overpriced.. or both :D
It will be a decade or so probably before it'll be an affordable option. But. One of the huge benefits it that there is no complex tooling / molds. Like carbon and alloy frames that have all the hyroformed tubes as well as much more welds. No tooling investment means they can change / improve / customize the bike easier and faster.. more different sizes can be made...
We helped Sturdy with their development on this - fantastic to see the finished article. Here's an overview of the development process - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-4Ga77SL5XUU.html
The use of video of FDM printing is misleading. This is SLS (Selective Laser Sintering) and is not the same process as shown in this video. No you won’t be able to do this at home even if you can weld Ti. You’d need to send the design off to a SLS house to print in a giant vat of titanium powder. And you pay for that entire vat of powder regardless of how little you use to make the object.
Actually this process is EBM, not SLS, built on an ARCAM Q10. For both SLS and EBM you do not pay for the entire chamber of powder, the powder is very simply reclaimed for use, you pay for the machine time, a small portion of powder (between £100-£200 per kg, depending on material) and the skill of the AM engineer who is setting up the build. No lasers involved, just electron beams.
Yes and the questionable value of using titanium in the first place is greatly reduced by the fact that it's notoriously brittle where is hasn't been carefully heat treated for annealing and tempering. Such as welds. Of which this mix and match design has many. For a start only a few parts are 3d sintered. The rest is welded to normal pipes. It's the long way around to produce an inferior product. Justified by claiming some parts have to be wacky shapes, which isn't even true. Ollie might only be an organic chemist but even he should know being forced into dodgy heat treatments on metals is both polluting and expensive. Titanium is energetically very expensive to produce normally. For this tech, first you have to make it pure. Then you have to grind it into a powder then you have to melt it back into a solid. Then you have to melt the ends to join them. This is only ever going to be a niche technique. Hang it on the wall with the other models.
You say that you hadn't seen a titanium fork on a bike before, but in fact the largest titanium bike manufacturer in the USA "Lynskey" have been offering them on their bikes for about 20 years now.
3d printed is a bit misleading considering all the machine work that takes place afterwards. More like 40% of some of the frame components have been 3d printed is more accurate.
@@appa609 For sure and understood. My point was given the tubes are not printed can you really call it a printed frame? Seems more accurate to describe it as a "regular" frame with printed lugs doesn't it?
Title is a bit misleading, this bike has 3D printed elements, that doesn't make it a 3D printed bike. And this approach has been around for a while, companies have been building bikes with 3D printed lugs and also opening up their IP to others, case in point ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-GCg7OKaariQ.html So it's not like this fella discovered that the earth isn't flat, he's just using what's out there and building bikes on that.
If he is of the same breed like Florian Wiesmann (famous custom MTB builder from Switzerland), he definitely has absolutely no interest at all in mass production...
First: Why are you showing the same clips of something 3D printed in PLASIC over and over again? Secondly: I would have loved some more clips on how the thing is actually made.
Firstly guys why are you sat together not wearing masks? You have a duty to set an example to the public, and millions of subs you have. No wonder the UK is so destroyed with infection rates. Even if you don't think you need it, set an example. Secondly, why keep showing 3d printed plastic clips?
I think that Bastion, the Australian company was the first to use 3D printed components in bikes to final customer. They blend 3D printed titanium lugs with carbon tubes to make an amazing bike. All the frames are custom made!
i've always loved titanium bikes, even over carbon. a disc-braked titanium bike originally designed as a gravel bike is a little slower than a carbon-based road bike but is far more versatile - you can put wider tires on the thing and it makes a great off-road bike as well.
8:50 I'm sure the welds are strong enough and all that but the idea of having a joint 1/3 of the way down the fork blade just gives me the fear. Probably completely irrational of me but still...
Hasn't Ozzie brand Bastion been 3D printing Ti lugs on their frames for 4-5 years? Also, Merlin came out with Ti forks back in the 90s and they quickly abandoned them when they would flex so much under braking, the front wheel would rub against the down tube. Hopefully this dude can tune the stiffness to avoid that.
Q. How strong are the castings? A. It's expensive to find out and I've done various testing, which is expensive for testing but I did test many sorts of parts and it was expensive to test those part and shapes, which I tested. Expensively.
It is a nice looking bike, but at 1.2kg, that frame is heavier than my Litespeed T1 frame. I am sure it is more aero, but neither is a triathlon or TT frame.
Lots of Marketing shit chat. Where are the data from a test lab? I’d like to see test data from classic titanium tubes vs 3D printed titanium. I’d bet that 3D values are far below. No trust from my side until these numbers are on the table. Stoped watching after around 10min in as talk shifted to anodizing.
Steel tubes are drawn to get the crystals to align and the strength properties that they desire. Aluminum frames are heat treated to get the material to respond correctly. At the 6-minute point , the manufacturer addresses mechanical properties. He says that all these manufacturers use slightly different techniques. He says that the manufacturers hold on to that information. Therefore you don't know what you're buying.
Titanium has nothing to do with ride comport it’s just the limited design choices force designers to Bild an compliant frame If u threat carbon or alloy property u will get similar results only with some slightly differences in weight and shape
Shouldnt the cuts of 3D printing show how theese oarts are printed? As they are made with powder titanium that gers fused together, not filament based that is being cut to.
I own one. It is outstanding. That said it's a titanium lug/carbon tube composite, so not truly a "titanium" bike. But, yeah, 3D additive manufactured titanium parts with carbon tubes wound in-house at Bastion. So I'd argue in support of Bastion's claims that the carbon tubes offer stiffness whilst dissipating "road buzz" through the tube weave. Their whole approach was completely custom, from fit (with Riderfit on-site) to design. It definitely wasn't cheap, but it's a bike for life and a one-of-a-kind.
Personally speaking it would have been a great introduction to know how Tom got to where he is now? From School to College Uni. How he got into design and build etc... Good interview though.
More click bait GCN. It's NOT a 3D printed frame as implied, it's a lugged bike featuring tubes with 3D Printed Titanium Dropouts etc which Bastion Bikes have also been doing for years although they utilise carbon tubing. It's nothing new.
I get your point, bet say, handmade tubs also aren't made with bare hands and no other tech. Tools and materials used in them have a bit or lot of automation.
One of the very best GCN videos ever; Tom - eloquent superhero, Oli - enthusiastic and all the right questions, the bike - a gorgeous jawdropping masterpiece. Now, how does it ride?
@GEORGIOS PAPASOTIRIOU Allow me to elaborate on my point here. First, You borrow your mother in law's multi-million-dollar 3D printer to make yourself an equally multi-million-dollar 3D printer, remember to write your name on it. And then you use your own multi-million-dollar 3D printer to print a robot, remember to make it an engineering genius, then you're all set.
Very interesting video. I do hope GCN makes more videos like this in the future. Some single speed-fixed gear content would also be nice. There's interesting topics there too, without overlapping with road bikes
The new "start with a marketing poll" format is really off-putting. We all know that GCN needs to make money, and I've watched my share of GCN sponcon, but this is just too blatant for my taste.
I think it's engagement farming, not marketing. I doubt any big brands are paying for information on the consumer demand for additively manufactured titanium bikes 😂
"I thought it was going to be more than that ! " 🤣🤣🤣🤣 Seriously,as beautiful as it is surely its more about how long it takes to print a lug thats the costly part,still il stick with a carbon endurance frame that doesn't cost as much as a small hatch! Something like a allez sprint maybe!
Not worth it. The crystal structures formed in printed titanium arent solid and usually have small micro air pockets that will result in cracks. Crash the bike and it breaks the next thing you know you have half a bike frame in your abdomen 😊
It won't be long before some Chinese bike company starts 3D printing Titanium bikes and makes then affordable. These 3D printed lugs would fix all the quality issues you would normally get with Chinese Titanium frames.
Ollie ..did he say how long it takes to actually print the components? Also 10k for a bike of this quality...potentially made to fit you perfectly from the ground up..and the only one you will ever need for the rest of your life. Suddenly the price seems pretty damn bearable... ...
Would be concerned about the rigidity of the fork when cornering and in descent. Wondering if it being a monocoque design (including steerer tube) would increase the rigidity without compromising suppleness? Overall though, a unique and beautiful bike.
Not the most beautiful bike, but definitely interesting and bold from the engineering point of view. What about the rider weight? How much the frame can withstand, when manufactured using this method?
Check out UHRWAHN BIKES IN GERMANY, similar process but in "Fe " sintering, 0,9 mm tubing almost exact looking lugs but "FE" powder technology use. Offered them Nanosteel tech but so far they think that powder is sufficient. Bikes are gorgeous pricy over 3 000,Euros
I'm actually in the market for a new bike (fresh from a bike fit) and would LOVE to have one of these...BESPOKE, BEAUTIFUL and, most importantly to me BRITISH.
Technically, the bike in not 3D printed. 3D printed elements included the frame lugs, fork, stem, and seatpost clamp. It is beautiful, but not in a class of its own. Bastion Cycles has long been delivering magnificent bespoke frames using 3D printed Ti lugs and Bossi Bicycles has modern looking bike with unique Ti cast lugs and Ti hydroformed tubes.
Nice looking bike. I like the anodizing for a bit of color. But those prices are OBSCENE !!! Also, for that price, I would want the finish to be perfect, which it is not. Also, can we stop with all the aero nonsense please? It's getting tiresome. A beautifully built classic road bike will look great for years to come, and is upgradeable, whereas all these aero bikes with specialized stems and bars and bits will gather dust in a few years because nobody will be able to find spare parts to replace broken or used ones...
Strange that the welding is performed without extra gas shielding devices. Ti has 4,5 in density compared to Al with 2,7. Steel is 7,8. Additive manufacturing will increase its market share as prices go down.
Why anyone would want frame for a lifetime? When elder you will not be able to ride what you used to lean over in your juice decades. Your kids will not ride bicycle because you pushed them too hard onto bike and they will have flying hoverboards on Mars, anyway. So only your other part left after you'll pass....same person who argued about dirty bike and money/time spent on it. Really?
Titanium cranks and stem?? What's the point, other than saying "I've got titanium cranks and stem"? There are much better material choices for those components, and yes, I own a titanium frame bike, two actually, that I thoroughly enjoy.
Nothing in this video shows us any "3d Printing". The stock footage is some 3d printer printing plastic on for an unrelated item. Would you like to see the thesis statement in the title supported by some footage? Let us know in the comments below!
Looks good and I'd buy it......if it's about £1500 as a frame set. The lugs aren't new bastion in Melbourne use this tech to make 3d titanium lugs then glue in carbon tubes.
Hot or not? Are you crazy? Surely the choice should be hot or very hot? Now, how much can I get for a kidney? I could save a bit by not needing mudguard lugs, this would be a fine weather bike only.
when asked about its strength he said very few ppl know its strength including myself but we're not going to tell you, which means its weak especially since having a rough vs polish finish makes a difference. imagine rough steel was weaker than polished steel ppl would laugh.
"Would you ride this beautiful 3D Printed Titanium bike?" It depends; would I need to wear the hat? Would I need to clip on two water bottles? How would I adjust the seat height?
Titanium cannot be 3D printed , only plastics and even concrete. The part could be printed in a type of plastic then that could be used as a mold to be sent to a foundry to make the titanium casting. To be accurate
No, I wouldn't ride it. If the testing that is going into durability and quality of the parts is that much of a secret then it is probably not as safe to ride as traditional building processes. 3D printing metals is not something we know enough about.
great video and work. I am riding a custom made titanium frame from the Swiss manufacturer highlite. 3D is interesting here but I miss these weldings on a traditional frame I have to say.
I respect and understand the simplicity of the single chain ring but for me, make it a compact double and it’s perfect. Absolutely love the material craftsmanship. I own a Moots Routt RSL and love it. Had a Pinarello Dogma 2 for several years and the Moots has become my one bike, all road and Swiss Army knife of any bicycle I’ve ever owned. Peace.
