Thanks everybody for your answers.
I knew one could not get 0.1 mm. easily. As usual, I will be following most of
the ideas people from the list have given away (FREE!!, and this I really
appreciate).
In fact, the final part for my prototype would be made of metal. Again an easy
question, Which is the best RP method to make a mold to make rapid metal parts?
I know there are several indirect methods I can use, building a master pattern
with some RP machine... but, how about making the mold directly with an RP
method? In this case, I believe I should forget about good accuracies...

Thank you folks.
