FCA US LLC is using 3-D printing to open a unique window on the world of axle development.
Conventional methods of evaluating oil flow inside axles and pinion carriers involve cutting windows into the components and then observing the fluid’s movement using a dynamometer. But with movement, oil turns milky and blocks the view afforded by two-dimensional windows.
So FCA US engineers decided to add a third dimension to the process by printing see-through plastic components exclusively for test purposes. This new technology allows correlation to virtual analysis of fluid flow.
