This is a cross-post with "It arrived!" but I figured it was of interest here, too.
I used FUD prints to make rubber molds, and then used those molds to produce wax positives for casting in sterling silver. I'm very happy with the results! This process is a lot more work than printing directly in silver, but its much cheaper (especially for making multiples), it easily allows multi-part pieces without having to pay the startup costs for each one, and overall allows a lot more control.
