The Swedish engineering company, Sandvik, was approached by GSD Global to improve e-bike production using titanium additive manufacturing. Together, the companies developed a 3D printed motor node, which they claim is both significantly lighter and cheaper to produce than the traditionally manufactured parts. A major advantage of this new technology is 75% cost reduction and substantial improvements in quality and sustainability as was claimed by GSD Global.
Using additive manufacturing for e-bikes
The titanium components, which hold the electric motor onto the bike frame, are notoriously difficult and costly to manufacture using CNC machining. To overcome this financial challenge, GSD Global, who has partnered with Bosch eBike systems for close to a decade, reached out to Sandvik to explore the possibility of using additive manufacturing to produce the premium e-bike part.
Higher quality and more durable
“Additive manufacturing proved to be the solution GSD Global was looking for as it enabled them to reduce the cost of the part by up to 75%. The printed component, made of Osprey Ti6Al4V powder, is also of a higher quality and is more durable than the original,” Sandvik explained.
