What it needs
- Desktop UV printers
- With prep eufyMake and xTool both describe printing directly on 3D-printed parts, with light sanding for slick PLA; the sources cover filament parts, not resin. [1] [2] [4]
- Primer or adhesion promoter
- Not stated
- White ink
- Not stated
- Flat or curved
- Not stated
How long it lasts
- Outdoors
- eufyMake says UV prints on plastic can be used outdoors (license plates, pool labels); the statement is not specific to this plastic. [3]
What goes wrong
- Parts can warp from lamp heat unless stuck firmly to an adhesive board (eufyMake).
- Rough or textured parts with more than about 1.5 mm height difference cause head strikes or lost detail (xTool).
Before you print
- Light sanding helps slick surfaces like PLA (eufyMake).
- Wipe dust off with a lint-free cloth; use alcohol for embedded grime (eufyMake).
- Press the part firmly onto the adhesive platform board (eufyMake).
