How long it lasts

None of the sources gives dishwasher, outdoor or scratch figures for chrome-plated and polished metal. Test a sample the way it will be used before you sell it.

What goes wrong

Mirror-like surfaces reflect UV lamp light, and ink can harden near the print head and clog nozzles (Roland).
Highly polished metal can reflect UV light and affect print quality (eufyMake).
