laser filler
You can add filler with a laser. Mold repairs are frequently done with filler. But this gun thing? I have never seen one live.

hand held laser welding
Has anyone been using laser on their metalshaping? It looks like magic in the video. They are no longer priced out of reach. Similar to high end TIG.

Great process, and versatile. I have made dedicated tools with broken broaches. But it was a lot of work and it only did one size.
Thanks for sharing.

drilling

I would use a router or chisel to cut the grooves in a wooden hammer form. Then pound it in with a rounded punch. You could also form the perimeter flange on the same hammer form. One of many ways.

CNC data
CAD and CAM systems can be crazy expensive. Not worth buying unless you are going to do a lot of it. A seat of Solidworks and MasterCam can run $20k (US) with all the add-ins.
