I use Orca mugs from MDP and after a few moths the coating started to come off the ones I used in the house and I don't have a dish washer, I swapped to 10oz mugs and they print without every little pressure, after reading these comments I think I'll switch to xpres

I don't have a dishwasher but they still faded, maybe it's an issue with your supplier as it only seems to be MDP mugs

The problem you have is that the coating has not been cured properly.
I have seen this a few times in my years and it can be sorted (not that you should have to). All you need to do is put the plain mug in an oven for 15-20 minutes to cure the polymer coating properly. Unfortunately there is no way you would know to do that so you are somewhat buggered.

Thought I'd revive this thread as I'm having this same issue with the 11oz Orca mugs from Xpres. Had 6 customers reporting their mugs fail now (albeit out of thousands) and all stock from Xpres.
First ones were purchased on or around October 2025.
Concerning that I'm not the only one and even more concerning that it's two suppliers so far.

Surely this shouldn't happen then if you're printing mugs in an oven? Our mugs are in the ovens for 17mins 50sec at 180 degrees and we've still seen this on a few mugs.
