Testing materials, choosing PA12-CF
After trying several materials, we are currently using PA12-CF to meet the strength requirements of this part.
PA12-CF is nylon 12 reinforced with carbon fiber. It is a 3D-printing material valued for its stiffness and dimensional stability.
Reinforcing across the print layers
Layer separation is one of the failure modes that needs attention in layer-by-layer 3D printing. Our prototype uses aluminium screws inserted perpendicular to the layer planes to reinforce the hub across the layers.
In this test, the reinforcement helped reduce breakage associated with layer separation.
Planned as a set with original aluminium parts
The aluminium components shown in the photos are currently borrowed from the Kyosho RB7.5. The retail version is planned to include our own original aluminium parts.
Three toe-in options planned
We plan to offer 0°, +0.5° and +1° toe-in options, at as accessible a price as possible so drivers can try different setups.
Testing and refinement will continue as we prepare for release.
