How long it lasts

None of the sources gives dishwasher, outdoor or scratch figures for AirPods and earbud cases. Test a sample the way it will be used before you sell it.

What goes wrong

  • Depending on the case type and material, printing may be difficult (Mimaki).
  • Soft rubber, silicone and low-surface-energy plastics shed ink (xTool).

Before you print

  • If the case is silicone, eufyMake says to prep it with a silicone primer or coating before printing.
