3D Printed Bike

thingiverse

This is something truly new, something anyone can do from now on - print their own bicycle frame right at home! With some SolidWorks skills under your belt, you can also craft a customized version that's tailored to perfect ergonomic needs. Designed by Stephan Schürmann. Here are the instructions: We printed the parts with XT-CF20 using an Ultimaker Original Plus equipped with a 0.8 Nozzle and 100% infill. To achieve great layer bonding, print slowly at a speed of 35mm/s. To build this bike, you'll need other components, so here's your shopping list: frame tubes, bottom bracket, bottom bracket housing, pedals, crankshaft, wheels, headset, fork, chain, sprocket, M6 screws - specifically for the seat clamp, 2K glue (a two-component gap-filling polyurethane adhesive), and handlebar (if you don't want to print it). Here are the tube sizes needed 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 We created a special glue distribution system because the glue is quite nasty stuff! You'll need a 2K polyurethane glue syringe with a mixing nozzle. After printing all parts, stack them together along with the tubes and push the glue through the inlets between the tubes and the 3D printed components. The runner system will guide the glue automatically to the right spots. This design is more of a proof of concept - it shows that such a project can be done with 3D printing. We've performed no safety testing or durability assessments whatsoever. Consequently, we cannot accept responsibility for anything you do (print) with the filament.
