I am familiar with laser welding, often repair or modify injection mould tools with the process. Basically it doesn't ruin the steel/ali and is far more localised to just the area you want to weld. For instance on a recent tool my client welded all the witness lines where inserts were and then machined back to the original surfaces leaving it witness line free. Childs play compared with this machine
I have never come across one of these amazing machines that DMG Mori have produced. Basically you build the part up you want from nothing with a laser metal deposition process then the machine is programmed to mill off unwanted/tight tolerance areas - all in one machine!
It's a pretty amazing process well worth watching the video
Extra reading here to explain the process and how it's different.
