Hey you 3D printing enthusiasts!
So this is what’s possible with everyday’s 3D printers and a suitable filament: the XT-CF20 bike
I’ve been working on this 3D printed bike during the past 5 months and now we are ready to publish this, it works like charm 🙂
We’ve used an Ultimaker Original Plus with a 0.8 nozzle to print these parts. Only the handle has been printed on the STACKER.
Printing the entire bike frame would take too much time and material, so we decided to print the lugs and connect tubes to them. The result is an amazingly strong bike frame at an acceptable weight.
The big benefit of making your own bike is that the sizes of the bike can be customized manually before 3D printing to preserve best ergonomics. Various types of tubing can be used including carbon, titanium, aluminum or bamboo.
3D printing allows a huge freedom of forms and allows unique features in the design. This has been used to implement a new kind of adhesive distribution system. With this technique one can assemble the bike and add an polyurethane adhesive which distributes itself to the right places without getting your hands dirty. The strength of the bike frame has been tested with a FEM analysis and, of course in real life use.
the XT-CF20 bike can be downloaded via GrabCAD: https://grabcad.com/library/xt-cf20-bike-3d-printed-bicycle-1

Woah, what possess I just read?? This will certainly
be actually eye-opening! I think that folks simply overlooked actions to make significant information today.
May be just https://restoringallthings.org perform that, as well.
Many thanks for such a fantastic article, I knew a great deal!
How many spools of XT-CF20 is this estimated to require?
3 or 4 spools

Hi Cagan. I think You’re absolutely right! If You had an accident with this bike, You definitely should get all the money from the manufacturer as a contribution. But wait, who manufactured the bike… You printed it… oh, it’s You! So, You already got all the money from the manufacturer! Be proud of Yourself!
Hi Jos
I really like the idea and the initiative. I have a question where I can find the material data (XT-CF20) for a Solidworks Simulation ? I would like to improve some parts but I can’t make any stress simulation without knowing the exact numbers for the XT-CF20 . As manufactures I supposed you have all that info and I would really appreciate your help.
Thank you!
Hi Jose,
Please check out our material data sheets here: http://colorfabb.com/materials.
This is the data we have readily available.
I see a SolidWorks simulation requires much more data, but please keep the following in mind.
All the data we have (also in the data sheet) is for the raw material.
The manner in which you process the material (type of printer, settings, environment, etc.) will heavily impact the final performance of the part in terms of strengths and weaknesses.
The SolidWorks simulation is also not equipped to handle variations in strength when comparing in-layer vs. perpendicular to the layer strengths.
If you have any questions regarding the strength simulations etc. I can put you in touch with Stephan who has built the bike, he can probably go more into detail.
Please contact us at support@colorfabb.com if you wish to discuss this with him.
to Cagan:
I think its very pusillanimous of you to be so worried about getting compensation. You downloaded the files, you made the bike, it’s up to you to test it and evaluate.
why are you looking to blame and/or get money from other people like that?
You don’t have to build the bike. No one is making you.
The CF team have made a fantastic contribution to the field. If you are afraid to use it- don’t.

Is there any guarantee certificate about this 3d printed bike. Can you guarantee me when I had an accident with a car because of a problem with this 3d printed bike at that moment? For example tubes or handle can be broken… Any guarantee certificate that you can supply to me?

One of my followers asked a question to me like that but I have no answer for him because I don’t know the quarantee scope of this 3d printed bike. Here is the question: “When someone had an accident with a product, if the reason of accident was the tool/vehicle in this case the one who had an accident because of this 3d printed bike has a right of compensation to the manufacturer…” So now, you can give me a clear explanation about the guarantee scope of this 3d printed bike. Thanks…

1- Who gives the guarantee certifiicate of this 3d printed bike? 2- When someone had an accident with a product, the one who had an accident has the right of a compensation to the manufacturer as legal… What is your answer about this problem? Is that all under my control???
Hi Cagan,
This design has to be seen as a proof of concept, demonstrating that such a project can be achieved with 3D printing.
We have done no amount of testing regarding safety and/or durability.
As with everything someone prints, they themselves are responsible for the use and safety of their own product.
We work to supply high quality materials but we have no influence over what people do with it when they receive the filament.
Printer type, settings, environment and just about everything else can have a big effect on the final outcome of a print as well.
Therefor we can not take or accept responsibility for anything a user does (prints) with the filament.
Please also take a look at our terms and conditions regarding this, here: http://colorfabb.com/terms-conditions/#guarantees
