How do I access Engineering Items?

In order to make blue print based items, you need to have two things: an available Engineering Processing Station, and a Premium Account. You can find the EPS using the Finder icon on the bottom of the game screen, second from the right. There are multiple ways to achieve a Premium Account.

You can pay for one from the CE store, vote your way into one, buy one through the Festive Store, and even win one.

Watch for the frequent postings in the forum threads for those and other opportunities.
