Laser 3D printing process creates plane parts on the fly

Researchers from RMIT University in Melbourne have been using laser metal-deposition technology to build and repair defence aircraft in a process that’s similar to 3D printing.plane 3d printed parts

The technology feeds metal powder into a laser beam, which when scanned across a surface adds new material in a precise, web-like formation. The metallurgical bond created has mechanical properties similar, or in some cases superior, to those of the original material.

The team believes the technology could be “game-changing” for the aviation industry

“It’s basically a very high-tech welding process where we make or rebuild metal parts layer by layer,” said Professor Milan Brandt who is working on the project.
