Except for the massive byproducts created on earth to get through the "more expensive" phase. It would be deeply deceptive and cynical to sell that as "green", surpassing even today's deceptive selling of carbon capture and storage technology on fossil fuel power plants.

There will be an industrial chain taking aluminum from lunar regolith that's catapulted out to a Lagrange point and then the raw aluminum or printed products will be lowered to more suitable orbits by ion engines that spit out ions from lunar soil. Hate to be the one to mention it, but the military may well be paying most of the freight to set most of this up (covertly or not) since space based you-name-it including hypersonic projectiles are going to be more and more useful as the decades pass.
