Wood and bamboo. Things people make: signs, plaques, coasters, boxes in walnut, maple, cherry or pine. From the sources at the end, checked October 11, 2026; we haven't tested it ourselves.

What it needs

Desktop UV printers: With prep Makers say raw wood prints directly, but it should be flat, smooth and sealed if porous, and dark woods need a white base. [1] [3] [6]
Primer or adhesion promoter: Helps. A UV-compatible primer on porous or rough wood (xTool); eufyMake says UV usually needs no primer but advises sealing raw wood. [1] [2] [5] [6]
White ink: On dark or clear. xTool: darker woods need a white ink base layer first. eufyMake prints a white base first on wood so the grain does not interfere. [1] [4] [5]
Flat or curved: Flat or curved. Boards print flat. eufyMake notes UV printers can also print wooden cups with a rotary mode. [1] [5]

How long it lasts

Dishwasher: xTool says a UV ink layer cannot withstand dishwasher cycles. [2]
Outdoors: eufyMake says to seal outdoor or heavy-use wood prints with clear varnish. Longer says prints on wood and acrylic typically last about 5 to 7 years indoors. [5] [8]
Scratches and wear: xTool pairs wood boards with hard UV ink, which it calls scratch-resistant. Hard scraping, blades, keys or sanding will still remove UV ink; xTool says a clear UV varnish coat is the most effective fix. [2] [7]

What goes wrong

Dark woods look muted and murky without a white base layer.
Rough or heavily textured wood can exceed the roughly 1.5 mm gap under the printhead and cause head strikes or lost detail.
Warped boards change the printhead height and hurt quality; damp wood (over about 10% moisture) can warp mid-job or print unevenly.
Ink can soak into the grain of porous wood.

Before you print

Light-colored, fine-grain woods (maple, birch, basswood, pine) print best.
Sand along the grain through 120, 240 and 400 grit, then wipe with a lint-free cloth.
Wipe with isopropyl alcohol above 90% before printing to remove oils.
On porous or rough wood, apply a thin, even coat of UV-compatible primer and let it dry fully.
On dark wood, run several white passes before the color layers.
A clear gloss layer printed first closes the pores and keeps ink from bleeding into the grain.
Seal outdoor or heavy-use pieces with clear varnish.

Supplies

Look for an adhesion promoter sold for UV printing on solid wood, 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.
