So this is something truly new. From now on everybody can print their own bicycle frame at home.
With some SolidWorks skills you can also make your own customized version for best ergonomic.
Designed by Stephan Schürmann
We have printed the parts with XT-CF20 on an Ultimaker Original Plus with a 0.8 Nozzle and 100% infill.
Print slow (35mm/s) to get good layer bonding.
You will also need other parts, here's your shopping list:
bottom bracket housing
M6 screw + nur for the seat clemp
2k glue (We've used a two component gap filling polyurethane adhesive)
Handlebar (If you don't print it)
These are the tube sizes that you need for this design:
Head tube: D=36 d=34 L=180
Seat tube: D=28.6 d=27 L=651
Top tube: D=31.8 d=30.2 L=527
Down tube: D=35 d=33,4 L=627
Seat stays: D=16 d=14.4 L=581
Chain stays: D=19 d=17.4 L=365
The glue is a really nasty stuff, so we have invented a new glue distribution system. You need a 2k polyurethane glue syringe with a mixing nozzle. After printing the parts you stack them together with all the tubes and push the glue through the inlets between the tubes and the 3D printed parts. The runner system will guide the glue automatically to the right places.
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.
Therefor we can not take or accept responsibility for anything a user does (prints) with the filament.
