I've never done any EDM myself, but I've talked to some people who have.
From what they've told me, it's slow as hell, removes very little material at a time, and is only really good for the stupid hard stuff you can't reliably cut any other way. So it's the machine you go to when you break off a carbide tap in a half a million dollar injection mold, but forget exists the rest of the time.
Just curious, being that pic related is the answer to gun control...

3d printers are still a meme, if you want to make something useful and durable you need to be working with steel.
Come back to me when you have their budget.

Crates and crates of these fuckers hidden behind dry wall beside studs, tucked into metal vents, inside furniture, buried, under floorboards, inside hollow cinder blocks, in the cement of sidewalks with rebar. The government couldn't confiscate all these without demolishing the house hiding them and picking through the rubble by hand.
Something like that is what any authoritarian government deserves to deal with.

So what you are saying is make shotshell landmines with 3d printers. got it.

That's not Reddit spacing, you fucking newfag.
3D of the ones we can actually afford are useless for firearm making. If you're poor but still want to has, get a vertical drill press, you can make some neat shotguns with it.

Barrel is the really hard part, everything else yes.

you can easily 3D print in metal by taking a welder and using it as the extruder you can more than pull it off.
You'll still need to clean it up but it's still pretty good for getting something in the general shape.
If only people knew how easy it was to set up a machineshop, In India, they still use coal powered machines, one big steam engine and lots of pulleys.

You can rifle a barrel with a button and a hammer. Readily available tubes can be used for guns too, go for THICC walls and 4140 steel.
You do know that a lot of the mechanical properties get lost right? That thing is not melting the metal, every welding is a weak point for the piece. Also, what are you intending to do? What kind of piece? A sear/a trigger? A fucking drill press can make those with some modifications that are simpler -and about as cheap- as your fucking contraption. A receiver can be made using ready available capillary tubbing (for pistol cartridge firearms at least).
What's the goal of that thing and what advantage do you think it has?
Melting aluminium is also a viable option depending on your resources. Lost material casting is one of the few legitimate uses for 3D printers when it comes to firearm making.
