Printing ships?

How do you print ships? Do you need materials, or can you do it for credits

You can no longer do it with credits. You now must use materials by putting them in the chest, and remember to have a prismarine crystal in both slots of the furnace.
Build it like this except I think chest and furnace can be interchangeable.
Furnace* | Chest
Iron Block | Iron Block
*note you need a sign on the furnace and the prismarine crystals in both slots.

Also you can buy materials, off bazaar using /bazaar browse, or if you can’t find it or aren’t near it try going to a nearby Trade city and using the merchant to and a command that I don’t remember and buying materials from him for a set price per item.

Also this belongs in the Questions catergory
