Dutch Superbike producer Electrical Superbike Twente have collaborated with K3D, a 3D metallic printing firm, to provide a brand new cooling shell for its electrical bike motors.
This would be the first 3D metallic printed element utilized by Electrical Superbike Twente and paves the best way for the adoption of additive applied sciences throughout the electrical superbike racing business.
The collaboration started shortly after Electrical Superbike Twente encountered an issue whereas designing its second electrical bike. The staff realized that the manufacturing strategies they had been utilizing to provide the cooling shell had been insufficient for a excessive efficiency bike.

The restrictions of conventional manufacturing
Feitse Krekt, Technical Supervisor of this years Electrical Superbike Twente staff commented on the groups difficulties, “The cooling shell of the primary superbike encompass a number of components, which had been fairly laborious to provide, utilizing typical manufacturing strategies like turning and milling. For these manufacturing strategies, plenty of materials was wanted and due to this fact the top product turned out to be fairly heavy,”
He added, “Due to the turning course of, the wall thickness wanted to be larger than optimum, and we had been unable to chill the electrical motor as environment friendly as doable. Due to this fact we had much less energy than desired and typically wanted to decelerate to not overheat the electrical motor.”
On account of these points the superbike determined to contact K3D, a part of the Kaak Group, who focuses on metallic 3D printing. K3D was the primary firm within the Netherlands to amass a MetalFab1 3D metallic printer from Additive Industries, with which it has produced over 35,000 merchandise since 2016.

The choice to make use of K3D to provide this half gave them a freedom of design that conventional manufacturing strategies can’t present, as Jaap Bulsink, CTO of K3D explains, “The half has an optimum cooling efficiency because of the skinny walled design with inner channels on the best spot. This was solely doable with 3D metallic printing the place you have got optimum freedom of design. On prime of this the half had been designed for minimal weight. The half was printed first time proper and could be very correct and can be utilized immediately with none postprocessing.”
This isn’t the primary time 3D printing has been employed within the manufacture of electrical motorbikes. BigRep, based mostly in Germany, has created a totally practical 3D printed electrical bike, nonetheless the bike was solely made for design exploration functions and is at the moment not a viable business product. Elsewhere in bike design, earlier this 12 months BMW unveiled its 3D printed an idea body for the BMW S1000RR sports activities bike. It’s unlikely that this bike will ever see cabinets although both.
Electrical Superbike Twente is at the moment within the technique of assembling its bike, after which it is going to be examined and eventually revealed on the 24th of Might 2019, on the Kinepolis in Enschede, Netherlands.
