Case Study: Briggs Automotive Company achieves rapid, precision prototyping for the Mono R with Stratasys

BAC Mono R supercar breaks records with carbon fiber 3D printing

Briggs Automotive Company (BAC), creator of the Mono R supercar, faced a tight deadline to develop a highly complex, carbon‑fiber airbox needed for the Goodwood Festival of Speed. Traditional mold tooling and machining would have taken more than two weeks per prototype and risked compromising the intricate design and performance goals, so BAC turned to Stratasys for industrial additive manufacturing support using the F900 FDM production 3D printer.

Stratasys produced the airbox in FDM Nylon 12CF, a carbon‑fiber‑reinforced thermoplastic that endures temperatures above 140 °C, with F900 printing tolerances of 0.089 mm. The team printed accurate prototypes within hours, fitted them to the car for on‑track testing under >100 °C and high loads, and achieved prototype performance comparable to molded carbon‑fiber—slashing weeks from lead times and enabling rapid design iterations. Stratasys’ solution materially sped development and allowed BAC to incorporate additive manufacturing into future design processes.
