XponentialWorks, a combination of venture fund, advisory firm and product developer, has partnered with Arcimoto, an Oregon-based transportation innovator, to produce 3D print lightweight suspension components for Arcimoto’s Fun Utility Vehicle (FUV).
A rear swingarm, knuckle, upper control arm, and a brake pedal, were redesigned using ParaMatters generative design software CogniCAD. These parts were fabricated with the Eosint M 280 industrial metal 3D printer. Avi Reichental, founder and chairman of XponentialWorks, said:
“The entire redesign, from concept to parts, took only four weeks, further demonstrating how 3D printing technology is completely changing how we design and manufacture products.”
The Arcimoto FUV is a tandem two-seat, three-wheeled vehicle with a maximum speed of 75 mph (121 km/h) and priced from $19,900. In the essence of being energy efficient, Arcimoto sought to optimize several of its parts using additive manufacturing. ParaMatters’s CogniCAD enabled the automatic combination of different parts into one homogeneous assembly – a previously time-consuming activity.
Furthermore, the heavier components were lighted as a result of generative design. These will be validated to potentially replace the original parts. According to XponentialWorks, the weight of the rear swingarm was reduced by 34%, the knuckle component by 36%, the upper control arm by 52%, and the brake pedal by 49%. Mark Frohnmayer, CEO of Arcimoto, explained:
“Our mission to rightsize 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. The speed at which the XponentialWorks team has made meaningful weight improvements to core components of the FUV is truly impressive.”
