Yes , We can beam the Loch Ness Monster with laser beams but its not easy. The trick is to give screens a 3D relief and everything is inside of this calculation.

I think less nasty acid is required than to beam Copper to Scotty

Israel is using sun rays to concentrate and use at a surgery. And stereolithography uses mirrors to illuminate the photopolymer but its not easy and very very expensive.

Buy an 30 dollars printer , find the acid , beam to the polyester and you are ready. Even buying simplest chemical costs more.

Than buy 20 dollar palladium , prepare 250 cl solution , pour on the matrix , wipe with steel plate and contact print on a paper.

Thats the most cost sensitive process. And quality approved long time ago. You can make color ones also.
