What it needs

- Prints as is Mimaki and eufyMake show keycaps as a print target; neither says whether ABS or PBT needs primer. [1] [2]
- Primer or adhesion promoter
- Not stated
- White ink
- Not stated

- Flat bed. Mimaki prints off-the-shelf keycaps on its UJF-7151 plusII flatbed; the page does not mention a jig. [1]
How long it lasts
None of the sources gives dishwasher, outdoor or scratch figures for keyboard keycaps (ABS, PBT). Test a sample the way it will be used before you sell it.
Before you print
- eufyMake suggests decorating escape or function keys so textured prints do not affect daily typing.
