GRP turns to Additive Manufacturing for Lamborghini supercar exhaust
Graham Rahal Performance (GRP), a parts shop for high-performance cars based in Zionsville, Indiana, USA, has explained how its team designed and manufactured components for the Lamborghini Revuelto using an FX10 Additive Manufacturing machine from Markforged, Waltham, Massachusetts.

In its latest project, illustrated in a video released by GRP, the team explained how 316L stainless steel exhaust flanges were produced for the 1,000-horsepower hybrid supercar. Traditionally, these highly complex X-pipe components would require 30 – 40 hours of manual fabrication, often involving extensive cutting, grinding, and welding. Using the Markforged FX10, a Fused Filament Fabrication (FFF) Material Extrusion (MEX) AM machine, GRP reported reducing the process to a single digital design and build.
“What Markforged has done for us was a lot more cost-effective,” stated Rob Sorum, Fabrication Specialist. “I was surprised how well the 316L flange welded, with little to no contamination — and the flow was perfect.”
According to GRP, the result was a weld-ready, lightweight component with excellent flow characteristics and minimal post-processing. This saved fabrication time and cost while still delivering the performance characteristics suited for the demands of modern supercars.
Beyond high-profile builds like the Lamborghini project, GRP is also using the FX10 to meet everyday shop needs, including custom clamps, tooling, and fixtures. The Markforged FX10 features a modular build system that enables users to switch between metal and composite build engines. With a build volume of 375 x 300 x 300 mm, the FX10 is designed to enhance manufacturing productivity by producing strong and accurate tools and fixtures.
