If you used reusable plates as a base - basically a removable 3D printer bed plate - and just printed the raised parts for a plate directly onto it, that would seem like a pretty quick, filament-light way to produce plates that could be used to run off a few copies, before scraping the filament traces off and printing another plate. I wonder how few layers you could get down to and produce decent results?
