G-code and M-code are the foundational languages that drive CNC (Computer Numerical Control) machinery and 3D printers.

It looks to be the most exciting 3D printer to date, but can the 4-head design really hold up in a machine of this size?

[Dardy-7] has worked out how to use a lesser-used technique — incremental sheet forming — to get similar results with a CNC machine.
