Successfully printed out of stainless steel and antique bronze. Antique bronze really feels like it was forged long ago and survived through the ages, which is awesome. Stainless is ok, but looks unfinished. I tried printing it out of strong and flexible plastic to test the material, but it failed the final test, so it could not be printed... then again why would you want to have it in anything else than METAL anyway. Gold plated is the same process as antique bronze so it would print. Silver is untested, so I'm not sure if it would print or not.
