Won't bend uniformly. Have to solder cross-overs, etc.
If anyone ever came up with a laser printer cartridge that deposited
(real) conductive ink on flexible plastic sheet, they would make a
fortune.
the tricky bit would be getting the conductive particles to stick to
the charged drum (conductive particles won't stick to a charged surface)
and then they need to fuse at about 100C
Perhaps indium microspheres coated with some sort of flux-wax, but I think the
particles need to be magnetic too, lace them with iron fibres ...
perhaps toner loaded with carbon nanotubes instead, the particles
still need to be non-conductive until fused.
You might have more luck with a foil printer, buy you'd need to use a
metal less reactive than aluminium so it can be plated up to a
reasonable thickness after printing.
as I understand it foil printers work the same as thermal transfer
faxes. the back of a "web" is heated and a fusible adhesive binds it
to the paper, I don't know if you can put a foil cartridge in an
ordinary thermal printer.
