Homebrew PCBs

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....
