Three-Dimensional Digitization for Reverse Engineering of Obsolete Automotive Components

The maintenance and restoration of classic vehicles frequently encounter the obsolescence of original components that are no longer available on the spare parts market. To address this constraint, the design workshop Azur Media 3D, based in Nice, specializes in the digitization of physical structures. The company was commissioned to fully scan a Ferrari F40. The technical objective was to generate an exact digital replica enabling reverse engineering, the design of custom parts, and the adaptation of replacement mechanical or structural components.

Geometric and Material Acquisition Constraints
Three-dimensional capture of an automotive body requires the acquisition of complex surface data, including sharp contours, hard-to-access cavities, and materials exhibiting different levels of reflectivity. The operation also requires preserving the integrity of existing surfaces, prohibiting the use of adhesive markers or any direct physical contact with the vehicle. To meet these requirements, the workshop selected the Artec Leo 3D scanner. This wireless device integrates onboard processing capabilities that provide real-time visual feedback on the quality of the captured mesh.

The absence of cables simplifies the operator’s movement around the vehicle, enabling geometric acquisition without additional positioning tools. “For the owner, the use of the Artec Leo was a prerequisite because it allows intervention without risk, with high precision, while remaining agile during capture,” explained Mathieu Fabris, Director of Azur Media 3D.

Data Processing and Operational Gains
The deployment of this acquisition solution enabled completion of the three-dimensional scanning phase in approximately one hour. The raw point clouds were subsequently processed using the Artec Studio software environment. The software utilizes alignment and fusion algorithms to clean the data and generate a solid model compatible with computer-aided design (CAD) tools. The automation functions integrated into the interface reduced modeling time significantly.

According to the company, this methodology generated an estimated productivity gain of nearly ten hours across the entire post-processing workflow. “What makes the difference is the ability to move quickly from capture to a usable model. Artec Studio allows us to work much faster while maintaining a high level of precision,” stated Mathieu Fabris.

Expansion of Industrial Applications
Beyond the preservation of historic vehicles and reduced-scale reproductions, the resulting three-dimensional models feed databases that can be utilized for additional engineering and archiving operations. Azur Media 3D is also deploying these acquisition technologies for applications involving heavy industrial vehicles. The company recently digitized the architecture of a Renault Trucks utility vehicle as part of a retrofit project adapting the vehicle to hydrogen-powered propulsion, demonstrating the integration of 3D scanning into reverse engineering and structural modification workflows.
