European product designer Ralf Holleis has completed a new version of his 3D printed track bike made using titanium lugs. The new version is even lighter than the first and features a belt drive system rather than a traditional steel chain.
The original version weighed in at 5.68kg (12,49lbs) but the VRZ 2 is down to 4.9kg (10.78lbs). It features 3D printed titanium lugs and the frame tubes are made from ultralight dry-carbon. The reduced weight is due to an ultralight Lightweight carbon wheelset, a THM crankset with beltdrive.
The titanium lugs are made using a LaserCusing process which fuses titanium power with a laser into metal shapes. The frames geometry can be custom designed to fit each customer and custom software works out the angles for the lugs in order the frame to fit together correctly.
After the 3D printer creates the titanium lugs they are bonded to the carbon tubes and finished in a special protective coating.
