Talk:3D Printing restrictions and bans

There is theory for this

I do not own a 3d printer myself (yet), so I write this under the assumption that a 3d printer is executing code in a sense of a Turing machine ( I heard he term "G-Code" here and there).

https://en.wikipedia.org/wiki/Rice%27s_theorem

This is Rice's theorem, which had been proven. In layman's speak it says: "you cannot write a program that proves another program computes a something correctly". I think that would apply here.

And even if we would just look at a printed part on itself, we could understand it as its own program. Not literally, but imagine our world being a giant program and every part (your level of abstraction may vary between sub atomic to a whole car) being a piece of code and they all mingle together, giving us the experience we have.

Just my two cents. I hope it helps the argument. 217.89.146.254 07:19, 5 June 2026 (UTC)
