Last year we bought ink jet priner for printing "any material" and it's
not cheap. Definetly not a typical "homebrew" price. Anyway, it can
print any material like conductive, resistive or dielectric layers. We
print on ceramic (alumina) substrate, which finally requires fireing at
860°C, which is (again) not really homebrew task. There's many obstacles....
