PROCESS (3d printed titanium lugs)

VRZ 1. a tack bike frame with 3d printed lugs from Ralf Holleis on Vimeo.



VRZ is a track bike frame with 3d printed titanium lugs glued together with carbon fiber tubes.

This method allows to build custom frames in a short period of time.
You could change the geometry to what ever fits you best, then the lugs gets generated by a software.
The generated 3D files are produced with laser-cuseing process. Afterwards the printed parts need to be finished and bonded to the tubes.
THE VRZ 2 Belt version is 4.9 kg !!!
