You really need to contact companies who manufacture equipment for printed circuit board fabricators. The machines you refer to already exist. Chemical formulations include, in addition to ferric chloride , ammonia

eBay
or
Amazon [affil link] , cupric chloride, and sulfuric acid/hydrogen peroxide. What you use and how you use it depends upon the particular application. For a start, check out journals devoted to printed circuit fabrication (BIG hint on a starting place for an internet search)!
