In this Instructable, user Aric Caley breaks down their resin printed display cup build:

I wanted to add that in comparison to existing fancy coffee cups:

1. Display cup has a removable, machine washable insert
2. The insert is borosilicate non reactive glass so no unwanted tastes are added to your drink
3. Its insulated but not continuously heated, which is good to preserve the taste of coffee in particular. You don’t want to keep cooking your coffee which imparts a bitterness to the flavor.
4. You can also eschew the glass insert and put a can of your favorite cold drink and it will keep it cold.
5. You can keep other cold drinks cold in the glass insert.
6. You can forgo the fancy electronics and just use a printed paper insert, eg a photo or a kids drawing.
