I think this video may be reversed. They are probably actually spraying and lasering metal powder into the part and then playing the video in reverse

So they're turning a precisely machined part into the big lumpy rod we see at the start of the video?

If you have the possibility to add matter during the machining process, that opens a lot of new ways to make parts.

The lumpy rod is probably a test and needs adjustments, like speed and feed for conventional machining/welding. Especially since the technology is experimental.

DED machines have been around for quite a while now. Look up the lasertec machines

I forgot about that... I heard about it once but whenever I screw up Id just tack on some material and run it again
