I wanted to share a project I have been working on for a few months. What I have developed allows for any 3D printer to be able to engrave and machine nearly any conductive metal using electrochemistry.

Would a tungsten needle work better than a common sewing needle?

... the "lifetime" would be higher, so yes! ... another option are graphite-electrodes - but not so good with the pencil sticks, but "industrial grade" graphite, as it's used with common EDM machining smoking smiley

Sewing needles are cheap and work. They also common in many different sizes. However, they can rust over time. Graphite is a good idea. I will have to see if I can find something that will not break during auto homing. The electrode also acts as a probe.
