Will 3D Printing Help Repair Diesel Engines?

摘要

Cummins is working with Oak Ridge National Laboratory (ORNL) to develop a material to repair heavy-duty vehicle engines damaged by a million miles of ex- treme conditions under the hood. Instead of replacing an engine's cylinder head, the research team "scooped out" the worn section and used additive manufacturing, commonly known as 3D printing, to deposit a high-performance alloy better than the original casting.
