I was looking into chrome plating, and came up with a theoretical process on how you could chrome plate 3d parts. First, you would have to print the part of course, and assemble it. Sandblast it with extremely fine powder to get rid of the ridges on the print, and coat the whole thing in conductive paint. After that, electroplate it with copper, then nickel, and finally, electroplate it with chrome. Of course, i have not tried this yet, and it will be a while before i get my sand blaster up and running again. I have not used for five years now. I believe its from the correct period, the 30's!

Wouldn't another way of flattening be to just put the whole block on a hot surface and melt it flat? PLA melts around 190C and ABS around 220C
With ABS you could use a solvent like acetone instead of heat.
To prevent parts adhering you could put (say) strips of paper between. Just some ideas!
There are a few online notes about plating plastic. Vapour deposition is another way.
