Do I still need a mold?
[Yes, unless you want to scan your part and use a rapid prototyping technique to produce a duplicate.]
And can I make a resin from a preexisting mold? They Are made with Poly 72-40 I believe.
[Sure, but the mold release you'd use varies depending on the type of mold and resin. Get advice from the manufacturers of the particular ones you're contemplating, and try a test first, before committing to a major project.]
