Poly mugs

[harlequeen]

I have been trying to print some polymer mugs and I keep getting banding, even though there is no banding on the print. See the pictures below. Any ideas how I can correct this. I have an order to get out and can't send the elephant one like this.

I'm pressing on 190C for 160 sec in a mug press specifically for this size mug (6oz polymner). The fox was the first one I did, followed quickly by the other 2.


The pics aren't great as I'm using my phont indoors, but you should be able to see what I mean. Any help would be appreciated, I'm desparate. LOL

I take it you are using the metal inserts?

Looks like you forgot to preheat the puk fully up to printing temperature first.

Thanks all, I am using the insert but didn't pre-heat. I will give that a try.
