    Seven dome-shaped ceramic or 3D-printed reef structures are laid out on a weathered wooden dock or pier. The structures vary in color from terracotta red to tan/beige and show signs of marine biofouling, including barnacle and oyster shell encrustation, indicating prior underwater deployment. A wire mesh trap (likely a crab or lobster trap) and rope are visible in the background.

    Six 3-D printed oyster reefs sit waiting to be deployed into Mobile Bay in Coden, Alabama, July 9, 2026. The reefs were made from dredged sediment and printed out on a 3-D printer by the USACE Engineer Research and Development Center and brought to Mobile to help the oyster habitat in the Mobile Bay.
