Software, 3D Printing Deliver Suspension Lightweighting for Eco-Friendly Vehicle

XponentialWorks is teaming with Arcimoto, Inc. to design and fabricate lightweighted components for Arcimoto’s Fun Utility Vehicle (FUV), with the goal of reducing cost, improving performance and efficiency, and making the vehicle more environmentally friendly.

This will allow Arcimoto’s electric vehicles to drive farther on a single charge, improve acceleration, and deliver better handling―all while reducing part-production costs. 

The project team used Paramatters software to redesign and fabricate new parts with geometries that mimic natural structure, according to XponentialWorks officials, and promises significant savings in part weight. Lightweighted parts include: a rear swing arm with weight reduced by 34 percent; knuckle, lightweighted by as much as 36 percent; upper control arm, with weight reduced by as much as 52 percent; and brake pedal, lightweighted by as much as 49 percent.

“The entire redesign, from concept to parts, took only four weeks,” says XponentialWorks founder Avi Reichental, “further demonstrating how 3D printing technology is completely changing how we design and manufacture products.” 

The Paramatters CogniCAD software employs artificial intelligence (AI) to create designs given design goals and materials parameters entered by engineers. The AI can explore nearly infinite design permutations based on the design concept, and provide an optimal solution to lightweight parts, according to XponentialWorks officials. CogniCAD also can combine all the different parts automatically into one homogeneous assembly, saving on manufacturing time and cost while providing valuable lightweighting. Then, as is the case with the Arcimoto FUV, the lightweighted parts can be 3D printed using steel to produce the final product, or 3D-printed molds are made to enable cast aluminum or iron parts.

“Our mission to right-size the footprint of daily mobility means a continued commitment to optimizing not just the vehicle platform architecture, but all of its constituent parts as well,” says Arcimoto CEO Mark Frohnmayer. “The speed at which the XponentialWorks team has made meaningful weight improvements to the FUV’s core components is truly impressive.”
