I'm trying to build an hybrid from two keyboards (an ibm M and a G15), but I need to make a new matrix. Designing the matrix it isn't dificult, But then I don't know how to "print" the matrix.

I found several companies that make flexible circuitry and some of them exactly like this, but all of them in large quantities.
Looking for DIY, I found in Instructables a guide to make flexible circuitry on copper. But it seems to bend and deform too easily, unlike a printed matrix.

Anyone know a company that does this in little quantities, or another method to make one?

Some people have had success with loading piezoelectric inkjet printers with conductive ink for doing circuits on mylar.

woah, that's awesome. if you try this let us know how it goes

Do you know what type of conductive ink, because the one I found costs 600€ a can. ^^U

Don't worry about that, if I can make a matrix I'll put on the forums the results ^^

Not sure, I can't find it either since I don't know brand names. I just remembered reading an article on it awhile back. Sorry I can't be more helpful.

could you bond the copper foil onto a polymer film base? that might help it keep shape
eta: it looks like the pyralux already has a kapton base but it's very thin.. could it be epoxied down to mylar or nylon after printing?
