Case Study: Cummins achieves 50% faster restoration of its 1952 race car water pump with 3D Systems' Geomagic software and ProX metal 3D printing

Cummins Uses Geomagic Software and Metal 3D Printing to Get 1952 Race Car Running Again 50% Faster

Cummins faced a time-sensitive restoration challenge: the original, one-off water pump housing on its historic #28 1952 race car was severely corroded just weeks before the Goodwood Festival of Speed. Traditional sand-casting would have taken about 10 weeks, making a timely repair impossible without a faster, reliable manufacturing approach.

Cummins used CT scanning and 3D Systems’ Geomagic Control X and Design X to reverse-engineer the part, converted the model in PTC Creo, and had 3rd Dimension print the final component in corrosion-resistant LaserForm 316L stainless steel on a ProX DMP 320. The pump housing was 3D printed in three days and the full process took five weeks—50% faster than casting—mating perfectly with existing components and delivering like-new performance during multiple runs at Goodwood.
