European product designer Ralf Holleis created this stunning super lightweight track bike using 3D printing technology. The VRZ 2’s 3D printed lugs are made from titanium alloy and the bike’s frame is made from ultralight dry-carbon tubes. The bike also features ultralight wheels, a THM crankset, and a noiseless belt-drive – all of which add up to an incredibly light weight of 4.9 kg.
Holleis’ VRZ 2 bike sheds light on how much work is actually required to create a perfect 3D printed product. His process isn’t the most straightforward, but it can be used to create custom frames in a short period of time. Anyone interested in replicating his process can change the bike’s geometry to suit their own specifications, after which a piece of software will generate the lugs. These pieces are produced through the process of lasercusing, and then the printed parts are finished and bonded to the tubes.
Regardless of whether you would want to tackle a project like this on your own, it’s worth taking the time to watch the video below to see just how much work goes into many of the 3D-printed projects that continue to make the rounds online.
