We know that F1 teams over the years have gone through lots of fancy
processes and materials to cut the weight of parts and still be strong.
I've been looking on Youtube and found a process called "electric
discharge machining", which gives tolerances of the thickness of a thin
wire.

Would an F1 team use such machines to give effectively zero tolerance
cutting for mechanical parts? Looking at it it is amazingly accurate
cutting, far better than a CNC milling machine, but massively slower.

EDM (subtractive, precision tolerances, internal machining on conductive metals) vs. 3DP (additive, rapid prototyping of complex designs, light
weight structures in many materials, including metals)

How much actual metal is on an F1 car anymore? Not being snarky; beyond the powertrain (gears, engine, exhaust) is there anything that isnrCOt carbon
fiber anymore?

IrCOm not sure how much more you could shave off the powertrain without sacrificing safety or reliability.

EDM has been around for quite a while now and I dare say that if it brings a benefit to anything an
F1 team is doing they'll certainly be using it.

Steve Mould did an interesting vid on the accuracy and precision of wire
EDM a while back:

Spoiler: the two bits that fit together perfectly aren't cut from the
same block, as some material has to be lost.
