The restoration of vintage cars, especially those with a very limited production run, can be very expensive, complicated and time consuming. Traditionally this process can take well over a year and be very costly to complete. German 3D printing manufacturer Voxeljet uses state-of-the-art techniques to reduce the amount of time and cost required to refurbish this vintage Ferrari 312P Racer, allowing the project to be completed in a few weeks at a fraction of the cost.
Voxeljet used reversed engineering by utilizing mobile measurement arms that were able to generate 3D data of the cylinder heads. Voxeljet then used precise 3D printers to create seven sand components, including one of each the upper and lower box, and 5 sand cores that formed the entire cast of the block.
“Reverse engineering with 3D printing is by far the most efficient method for reproducing components that are no longer available,” explained Voxeljet CEO Dr. Ingo. “Often, it is the only way to reproduce certain components quickly and at reasonable cost. Thus there is considerable demand for 3D printing in this area. We are of course very pleased that our technology was a contributing factor in the successful engine overhaul of a Ferrari 312P.”
The name 312P, explains that the racer featured 3 liter displacement, with 12 cylinders, the “P” represents that the racecar was a prototype. The car’s 60 degree V12 engine is capable of putting out 430 hp, a number that at the time was unheard of. The 312P was introduced in 1969, the year that Ferrari returned to racing after protesting a rule change that banned their previous racecar from competition.
