CHALLENGE

A client restoring a 1921 Kissel Gold Bug Speedster for the 2018 Pebble Beach Concours d’ Elegance in Monterey California, needed to have a full set of four hood latches recreated. The time constraint and one-off nature of the parts concluded there would not be an opportunity to utilize traditional manufacturing processes to meet the deadline.

SOLUTION

The client sent a borrowed hood latch to serve as a design guide. The parts were quickly modeled and produced in 316 Stainless Steel and infiltrated with bronze using ExOne’s metal 3D binder jetting technology. Turnaround time on the parts was under 4 weeks which provided enough time for chrome plating and installation before the vehicle was transported to California. The vehicle won “Best in Class” at the show and was featured on Motor Trend TV’s “Long Road to Monterey” program.

THE EXONE ADVANTAGE

ExOne’s ability to produce high-quality components directly from design files significantly minimized production time, allowing HV3DWorks to meet the customers’ deadline. The 316 Stainless Steel infiltrated with bronze was an ideal material choice for strength and durability.
