Glass, ceramic and stone. Things people make: coffee mugs, personalized gift mugs. From the sources at the end, checked October 11, 2026; we haven't tested it ourselves.

What it needs

Desktop UV printers: With prep Needs a rotary attachment and, on glazed ceramic, a glass and ceramic primer; keep the print off the rim. [1] [3]
Primer or adhesion promoter: Needed. Glass and ceramic primer for glossy or glazed ceramic (xTool); eufyMake recommends a UV pre-coating liquid for glazed ceramics. Matte ceramic needs none (xTool). [3] [4] [7]
White ink: On dark or clear. eufyMake: UV printing can lay down white first for dark mugs. [1]
Flat or curved: Rotary or curved. eufyMake rotary takes cups 80 to 245 mm tall and 45 to 100 mm across, has a "With Handle" mode and tilts up to 13 degrees for tapered cups. xTool needs its OR1 rotary for mugs. [1] [2] [3]

How long it lasts

Dishwasher: eufyMake: prints may not always be dishwasher safe; some users report they hold up. xTool: hand washing is usually recommended. [1] [5]

What goes wrong

If the mug is not level on the rotary, the design can look crooked or blurry (eufyMake).
xTool: UV-printed areas are not intended for direct contact with food or beverages.

Before you print

Supplies

Look for an adhesion promoter sold for UV printing on ceramic mugs (outside only), and read its data sheet for how long to let it dry: adhesion promoter (Amazon US), adhesion promoter (Amazon UK). Clean with isopropyl alcohol wipes first. Test one piece before a batch.
