Using 3D Printing to Repair Diesel Engines

Instead of replacing an engine’s cylinder head, a research team in Tennessee used additive manufacturing to deposit a high-performance alloy better than the original casting.

“Diesel engine maker Cummins, Inc., is working with Oak Ridge National Laboratory (ORNL) to develop a material to repair heavy-duty vehicle engines damaged by a million miles of extreme conditions under the hood.”

 

“The goal of the process, developed at the Department of Energy’s Manufacturing Demonstration Facility at ORNL, is to repair vital engine parts without recasting and installing new ones. By applying the 3D printed segment, the engine is made stronger and its servicable life is extended, as well as saving the cost of manufacturing and installation of a new block.”
