What it needs

With prep xTool says painted surfaces need a dedicated primer and uncertain coatings need a small test batch first, while eufyMake counts coated wood among surfaces with strong adhesion once prepared. [1] [2]

How long it lasts

Dishwasher
xTool says a UV ink layer cannot withstand dishwasher cycles. [1]
Scratches and wear
eufyMake: on prepared surfaces such as coated wood, adhesion resists normal handling, but extreme abrasion can still damage the print. [2]

What goes wrong

  • The whole print peels off if the primer is missing or wrong for the coating, or the surface was not cleaned.
  • Grease left on the surface makes ink bead and print patchy.

Before you print

  • For spray-painted or specially coated surfaces, xTool says to use a dedicated primer for that material.
  • For spray-coated, plated or baked-finish parts and unknown finishes, test a small batch first.
  • Wipe the print area in one direction with an alcohol-dampened lint-free cloth; xTool calls incomplete cleaning the leading cause of poor adhesion.
  • If primer is used, extend the primed area 1 to 2 mm beyond the design so edges do not lift.
  • eufyMake suggests lightly scuffing glossy items with fine sandpaper to give the ink grip.
