Foundry can be accessed from the Bridge by going to Supply -> Foundry (bottom left). In the Foundry, Captains can craft gear using various materials, such as  Honkai Piece,  AE Imaginon, or the various types of Crystalyte obtained from Universal Mirage.

There's a restriction to how many items in total or per day can be crafted. 'Total' means that the Captain cannot own more than a certain number said gear, regardless of the way it was acquired.
