[How do I?] Making Electrode

[am161363]

I wanna make electrode for this product to engrave it using sinker edm
Any ideas?

Sinker EDM only works on electrically conductive workpieces, so I trust you want to make a
cavity (like for a mold) in the shape of those pieces? One approach would be to electroplate
the forms with copper, then use the copper as a tool to spark-erode some lower melting
metal (maybe zinc alloy).

Another way would be to program a mill to cut the desired tool shape in a block of graphite.
Graphite has good durability, could cut steel effectively.

To replicate the whole surface might take multiple tools, of course.
