Metal and coated metal. Things people make: insulated tumblers, skinny tumblers, travel mugs, water bottles with a powder-coat finish. From the sources at the end, checked October 11, 2026; we haven't tested it ourselves.

What it needs

Desktop UV printers: Limited LogoJET sells powder-coated blanks as production-tested for its printers, but makers say coatings differ and a coated piece should be test-printed first. [1] [2]
Primer or adhesion promoter: Not stated
White ink: On dark or clear. eufyMake says white ink acts as a base layer on dark or transparent materials. [5]
Flat or curved: Rotary or curved. Needs a rotary attachment. eufyMake E1 rotary: 40 to 100 mm diameter, cylinders, cones and mugs. xTool OR1 for regular cylinders; handles, complex curves or big steps in height suit UV DTF better. [3] [4]

How long it lasts

Dishwasher: Hand wash. eufyMake: dishwashers are the enemy of printed drinkware. xTool: UV ink cannot withstand dishwasher cycles. [6] [7]
Scratches and wear: xTool: ink cannot withstand hard scraping with keys or blades. Roland suggests a gloss ink layer for extra protection on heavily used surfaces. [7] [9]

What goes wrong

Some coatings bond better than others (eufyMake, in its UV DTF cup-wrap guide).
A surface with a glass coating or water-repellent treatment is hard to get ink to stick to, even with primer (Roland).

Before you print

Test one coated tumbler first (eufyMake, in its UV DTF cup-wrap guide).
xTool lists the tumbler primer as 'chosen to match the body material'; the maker pages reviewed do not say which primer suits powder coat.
Test print on the actual object before a real run (Roland).

Supplies

Blanks: blank stainless tumblers (Amazon US). Clean with isopropyl alcohol wipes first. Test one piece before a batch.
