CRP’s Motorsports’ Materials
The tradeoff between material stiffness and the weight needed to achieve it is a constant challenge in developing components for motor racing applications.
Additive manufacturing group CRP Technology (crptechnology.com) says SLS material balances both. Recently, the materials and design firm showcased that by producing several parts for Nissan’s DeltaWing race car. Those 3D printed parts included electrical breakout boxes, transmission seal covers with integrated pressurized oil feed passages, and a tow hook plinth, created with Windform XT 2.0 composite. CRP Technology and its CRP USA studio used carbon-fiber reinforced Windform XT 2.0 to construct the gearbox side covers, as well.
CRP says it now has used a similar process and materials for one if its own products, the Energica (energicasuperbike.com) electric motorcycle, for the street cycle’s headlight covers.
After choosing the style of headlight cover, the part was cast in polyurethane and later scanned with a FARO (faro.com) laser. CRP processed the STL cloud point file of the cover and imported it into a CAD file for the final geometry of the component. CRP used its Windform GF 2.0 material to forge the headlight covers, which were smoothed manually and then painted silver.
