This is the World's First 3D-Printed Carbon Bike

- Modern carbon-fiber bikes, stiffer and stronger than their metal counterparts at literally fractions of the weight, are technological marvels. But they have two drawbacks: The stuff is hella expensive, and it’s a quality-control nightmare.
Now, one tech company aims to change all that with the innovation of 3D printing.

Some of those claims are wildly inaccurate and some are just completely false. The weave is not cosmetic at all, it's weaved in that pattern to give strength in the x & y direction. It'd be a UD without the weave and provide no shear or torsional stiffness.
And that titanium claim? please...
wtf is that geometry tho?
What you see here is a frame with the structural integrity of a toothpick.
I think this is just a new Scam-digogo get-rich-quick scheme, and the bike will never make it to production (unlike SpeedX, which isn't saying much).

Did you make 100% carbon fiber? I want to make a bike frame with my 3d printer. which filament can i use? pla cf or nylon cf
...Which
CIA backed?
Most likely In-Q-Tel, the CIA's venture capital branch.
5 times stronger than titanium at a third of the weight. Unrivaled bullshit.
It is d process of 3d printing that makes parts week. The strength of 3d printed parts will always be weaker at layers, no matter what material they are using unless it is manufactured using sls, and using metals. The solution to this is to have a printer utilizing 5 axis, so it can print on all axis at one time to strengthen the part. Just my two cents.
However this isn't created as layers, Printwiz, and is nothing like conventional 3D printing. It's a continuous fiber process that lays down a criss-crossing network of fibers on multiple axes throughout the part, just like laying strips of unidirectional carbon fiber into a mold, creating fully-tuneable anisotropic strength (unlike traditional 3D printing's isotropic behavior - which, you're correct, would be terrible for something as dynamically complex as a bike frame.) There are continuous fibers running from the head tube to the dropouts, and the whole process is thermoplastic, not thermoset like traditional CF frame construction - meaning it comes off the print bed cured and with much more impact resistance.
Here is the problem. I can order about 500 bike frames "digitally machined" in China for about the price of one of these frames. I am also not investing $$$$$$ in a concept carbon fiber builder. Paint on carbon fiber bikes is expensive as well and it will not accept powder coating.
Looks like a NINER RDO Fork !!!!!!!!!!
"Five times stronger than titanium at a third of the weight". What? This statement kinda makes no sense. Actually, carbon can almost reach the strenght of a strong titanium alloy at a third of the density (weight). But only an unidirectional design. The downside of this design is, that it can't handle load from different directions as well and it's more vulnerable to impact damage. If it gets damaged, the cracks and fissures will continue to expand. Woven fibers don't have this issue, but the strength is lower. The best solution is a combination of both, but the strength is still highly dependend on a well component design. You can get stronger, more consistent and longer lasting components from titanium at not so much more weight. The greatest downside is that it's difficult to manufacture, which makes light and complex parts extremely expensive.
I'd like to add that critical carbon components, like the rims of a motorbike, require to be xrayed for internal cracks once per year. If your wheel explodes at 100+ mph, the bike and your remains could kill several other people aswell.
I want to know what price tag they would put on that bike
I recon getting the price below the average carbon bike is quite feasible, as the current carbon frame production process still involves manual steps mostly
You can buy an e-bike version of this very bike at emerybikes.com - check it out.
CF is not recyclable, at least not sustainably. So not on my list
The biggest problem with recycling carbon fiber is separating the matrix material from the actual carbon, because this material can't be melted. Making carbon with a 3d printer could make it possible to recycle
@@JWH.Design The material in these bikes actually can be melted because it is a thermoplastic similar to the plastic in your bottles or tupperware just way higher mechanical properties. Granted it will take a lot of heat... Majority of the traditional carbon fiber such as in airplanes is combined with thermosets, like epoxy resin, which can't be melted.
So is your laptop, so hand it over quick.
try wheelchairs guyzzz
This bike is not to my liking, it will be too expensive and would brake under my weight, I still prefer cro-moly MTBs.
whered you see the price?
so whatever happened to this?
still going, they have another company name called superstrata and they're taking early orders
Superstrata backers have gotten nothing but delays and excuses, you should see the comments on their Indiegogo campaign page.
Looks crap
It's principle is still layering carbon fibre, which still requires expoy, so many statements in this video aren't completely true. Check out Superstrata for an actual 3D printed bike, with customisable geometry to suit each person AND it doesn't look like some non cycling modern art moron designed it
Superstrata IS by this by this same company - you should look at the status of that project. Backers haven't gotten anything and it looks like a house of cards about to collapse.
why is it so expensive, though...
Please.push the technology, I don't wanna wait....🙄
stupid and heavy af
