Wood and bamboo. Things people make: plaques, signs, laser-cut blanks, coasters. From the sources at the end, checked October 11, 2026; we haven't tested it ourselves.

What it needs

Desktop UV printers
Prints as is xTool says MDF gives the most consistent results of the wood types because it has no grain variation. [1]
Primer or adhesion promoter
Not stated
White ink
On dark or clear. xTool: darker woods need a white ink base layer first. [1]
Flat or curved
Flat bed. xTool: UV printing works on flat, smooth wood surfaces. [1]

How long it lasts

Dishwasher
xTool says a UV ink layer cannot withstand dishwasher cycles. [3]
Scratches and wear
xTool pairs wood and MDF with hard UV ink, which it describes as scratch-resistant; a UV varnish coat is the most effective way to add more. [2] [3]

What goes wrong

  • Damp board (over about 10% moisture) can warp mid-job, change printhead height and print unevenly.
[1]

Before you print

  • Sand rough or untreated surfaces (120, 240, 400 grit) and wipe with a lint-free cloth.
  • Wipe with isopropyl alcohol above 90% before printing.
  • xTool's ink guide lists hard UV ink for wood and MDF.
