It requires capability to 3D print metal in some form, yes, but represents quite an advance over the need of precisely machine the shaped charge cone, it seems.

For such low precision charges there is no need for complicated machining, and simple stamping works, like Germans did in WW2 with PzF steel liner.

Ok, thanks. I wonder if a metal 3D printer could be more affordable/easy to install and operate than a stamping press.

By being absolutely more flexible than a press.

Wait..a...second! 

Didn't you say that really good HEAT ammo wasn't possible until they got input for nuclear weapons programs? 

Or is the HEAT in the video the budget stuff?

This seems to be the correct assumption.

A 3D printer would be easier to install, but stamping (or more reasonably forging) would be far less expensive, and at least a couple of orders of magnitude faster. As I was tought at a metal 3D-printing class. 3D-printing is great...if you want to make one or very few parts, or if the geometry means you have no other option.

Research was published long time ago, so nowadays (well, since the early '80s) non-nuclear countries also produce good shaped charges.

Very non-precision.
